A museum (/mjuːˈzəm/ mew-ZEE-əm; plural museums or, rarely, musea) is a building or institution that cares for and displays a collection of artifacts and other objects of artistic, cultural, historical, or scientific importance. Many public museums make these items available for public viewing through exhibits that may be permanent or temporary. The largest museums are located in major cities throughout the world, while thousands of local museums exist in smaller cities, towns, and rural areas. Museums have varying aims, ranging from the conservation and documentation of their collection, serving researchers and specialists to catering to the general public. The goal of serving researchers is not only scientific, but intended to serve the general public.

There are many types of museums, including art museums, natural history museums, science museums, war museums, and children's museums. According to the International Council of Museums (ICOM), there are more than 55,000 museums in 202 countries.

Etymology

The English "museum" comes from the Latin word, and is pluralized as "museums" (or rarely, "musea"). It is originally from the Ancient Greek Μουσεῖον (Mouseion), which denotes a place or temple dedicated to the muses (the patron divinities in Greek mythology of the arts), and hence was a building set apart for study and the arts, especially the Musaeum (institute) for philosophy and research at Alexandria, built under Ptolemy I Soter about 280 BC.

Purpose

The purpose of modern museums is to collect, preserve, interpret, and display objects of artistic, cultural, or scientific significance for the study and education of the public. From a visitor or community perspective, this purpose can also depend on one's point of view. A trip to a local history museum or large city art museum can be an entertaining and enlightening way to spend the day. To city leaders, an active museum community can be seen as a gauge of the cultural or economic health of a city, and a way to increase the sophistication of its inhabitants. To a museum professional, a museum might be seen as a way to educate the public about the museum's mission, such as civil rights or environmentalism. Museums are, above all, storehouses of knowledge. In 1829, James Smithson's bequest, that would fund the Smithsonian Institution, stated he wanted to establish an institution "for the increase and diffusion of knowledge".

Museums of natural history in the late 19th century exemplified the scientific desire for classification and for interpretations of the world. Gathering all examples for each field of knowledge for research and display was the purpose. As American colleges grew in the 19th century, they developed their own natural history collections for the use of their students. By the last quarter of the 19th century, scientific research in universities was shifting toward biological research on a cellular level, and cutting-edge research moved from museums to university laboratories. While many large museums, such as the Smithsonian Institution, are still respected as research centers, research is no longer a main purpose of most museums. While there is an ongoing debate about the purposes of interpretation of a museum's collection, there has been a consistent mission to protect and preserve cultural artifacts for future generations. Much care, expertise, and expense is invested in preservation efforts to retard decomposition in aging documents, artifacts, artworks, and buildings. All museums display objects that are important to a culture. As historian Steven Conn writes, "To see the thing itself, with one's own eyes and in a public place, surrounded by other people having some version of the same experience, can be enchanting."

Museum purposes vary from institution to institution. Some favor education over conservation, or vice versa. For example, in the 1970s, the Canada Science and Technology Museum favored education over preservation of their objects. They displayed objects as well as their functions. One exhibit featured a historical printing press that a staff member used for visitors to create museum memorabilia. Some museums seek to reach a wide audience, such as a national or state museum, while others have specific audiences, like the LDS Church History Museum or local history organizations. Generally speaking, museums collect objects of significance that comply with their mission statement for conservation and display.

Although most museums do not allow physical contact with the associated artifacts, there are some that are interactive and encourage a more hands-on approach. In 2009, Hampton Court Palace, a palace of Henry VIII, in England opened the council room to the general public to create an interactive environment for visitors. Rather than allowing visitors to handle 500-year-old objects, however, the museum created replicas, as well as replica costumes. The daily activities, historic clothing, and even temperature changes immerse the visitor in an impression of what Tudor life may have been.

Definitions by major museum professional organizations

Major museum professional organizations from around the world offer some definitions as to what a museum is and their purpose. Common themes in all the definitions are public good and care, preservation, and interpretation of collections.

The International Council of Museums' current definition of a museum (adopted in 1970): "A museum is a non-profit, permanent institution in the service of society and its development, open to the public, which acquires, conserves, researches, communicates and exhibits the tangible and intangible heritage of humanity and its environment for the purposes of education, study, and enjoyment."

A proposed change to this definition, which would have museums actively engage with political and social issues, was postponed in 2020 after substantial opposition from ICOM members.

The Canadian Museums Association's definition: "A museum is a non-profit, permanent establishment, that does not exist primarily for the purpose of conducting temporary exhibitions and that is open to the public during regular hours and administered in the public interest for the purpose of conserving, preserving, studying, interpreting, assembling and exhibiting to the public for the instruction and enjoyment of the public, objects and specimens or educational and cultural value including artistic, scientific, historical and technological material."

The United Kingdom's Museums Association's definition: "Museums enable people to explore collections for inspiration, learning and enjoyment. They are institutions that collect, safeguard and make accessible artifacts and specimens, which they hold in trust for society."

While the American Alliance of Museums does not have a definition their list of accreditation criteria to participate in their Accreditation Program states a museum must: "Be a legally organized nonprofit institution or part of a nonprofit organization or government entity; Be essentially educational in nature; Have a formally stated and approved mission; Use and interpret objects or a site for the public presentation of regularly scheduled programs and exhibits; Have a formal and appropriate program of documentation, care, and use of collections or objects; Carry out the above functions primarily at a physical facility or site; Have been open to the public for at least two years; Be open to the public at least 1,000 hours a year; Have accessioned 80 percent of its permanent collection; Have at least one paid professional staff with museum knowledge and experience; Have a full-time director to whom authority is delegated for day-to-day operations; Have the financial resources sufficient to operate effectively; Demonstrate that it meets the Core Standards for Museums; Successfully complete the Core Documents Verification Program." 

Additionally a there is a legal definition of museum in United States legislation in the authorizing the establishment of the Institute of Museum and Library Services: "Museum means a public, tribal, or private nonprofit institution which is organized on a permanent basis for essentially educational, cultural heritage, or aesthetic purposes and which, using a professional staff: Owns or uses tangible objects, either animate or inanimate; Cares for these objects; and Exhibits them to the general public on a regular basis." (Museum Services Act 1976) 

History

Ancient history

Bel-shalti-nannar's museum label (circa 530 BCE), first museum label known) in city of Ur (modern Tell el-Muqayyar, Iraq

One of the oldest museums known is Ennigaldi-Nanna's museum, built by Princess Ennigaldi in modern Iraq at the end of the Neo-Babylonian Empire. The site dates from c. 530 BCE, and contained artifacts from earlier Mesopotamian civilizations. Notably, a clay drum label—written in three languages—was found at the site, referencing the history and discovery of a museum item.

Ancient Greeks and Romans collected and displayed art and objects but perceived museums differently from modern day views. In the classical period the museums were the temples and their precincts which housed collections of votive offerings. Paintings and sculptures were displayed in gardens, forums, theaters, and bathhouses. In the ancient past there was little differentiation between libraries and museums with both occupying the building and were frequently connected to a temple or royal palace. The Museum of Alexandria is believed to be one of the earliest museums in the world. While it connected to the Library of Alexandria it is not clear if the museum was in a different building from the library or was part of the library complex. While little was known about the museum is was an inspiration for museums during the early Renaissance period. The royal palaces also functioned as a kind of museum outfitted with art and objects from conquered territories and gifts from ambassadors from other kingdoms allowing the ruler to display the amassed collections to guests and to visiting dignitaries.

Also in Alexandria from the time of Ptolemy II Philadelphus (r. 285-246 BCE), was the first zoological park. At first used by Philadelphus in an attempt to domesticate African elephants for use in war, the elephants were also used for show along with a menagerie of other animals specimens including hartebeests, ostriches, zebras, leopards, giraffes, rhinoceros, and pythons.

Early history

The old Ashmolean Museum building

Early museums began as the private collections of wealthy individuals, families or institutions of art and rare or curious natural objects and artifacts. These were often displayed in so-called "wonder rooms" or cabinets of curiosities. These contemporary museums first emerged in western Europe, then spread into other parts of the world.

Public access to these museums was often possible for the "respectable", especially to private art collections, but at the whim of the owner and his staff. One way that elite men during this time period gained a higher social status in the world of elites was by becoming a collector of these curious objects and displaying them. Many of the items in these collections were new discoveries and these collectors or naturalists, since many of these people held interest in natural sciences, were eager to obtain them. By putting their collections in a museum and on display, they not only got to show their fantastic finds but also used the museum as a way to sort and "manage the empirical explosion of materials that wider dissemination of ancient texts, increased travel, voyages of discovery, and more systematic forms of communication and exchange had produced".

One of these naturalists and collectors was Ulisse Aldrovandi, whose collection policy of gathering as many objects and facts about them was "encyclopedic" in nature, reminiscent of that of Pliny, the Roman philosopher and naturalist. The idea was to consume and collect as much knowledge as possible, to put everything they collected and everything they knew in these displays. In time, however, museum philosophy would change and the encyclopedic nature of information that was so enjoyed by Aldrovandi and his cohorts would be dismissed as well as "the museums that contained this knowledge". The 18th-century scholars of the Age of Enlightenment saw their ideas of the museum as superior and based their natural history museums on "organization and taxonomy" rather than displaying everything in any order after the style of Aldrovandi.

The first "public" museums were often accessible only by the middle and upper classes. It could be difficult to gain entrance. When the British Museum opened to the public in 1759, it was a concern that large crowds could damage the artifacts. Prospective visitors to the British Museum had to apply in writing for admission, and small groups were allowed into the galleries each day. The British Museum became increasingly popular during the 19th century, amongst all age groups and social classes who visited the British Museum, especially on public holidays.

The Ashmolean Museum, however, founded in 1677 from the personal collection of Elias Ashmole, was set up in the University of Oxford to be open to the public and is considered by some to be the first modern public museum. The collection included that of Elias Ashmole which he had collected himself, including objects he had acquired from the gardeners, travellers and collectors John Tradescant the elder and his son of the same name. The collection included antique coins, books, engravings, geological specimens, and zoological specimens—one of which was the stuffed body of the last dodo ever seen in Europe; but by 1755 the stuffed dodo was so moth-eaten that it was destroyed, except for its head and one claw. The museum opened on 24 May 1683, with naturalist Robert Plot as the first keeper. The first building, which became known as the Old Ashmolean, is sometimes attributed to Sir Christopher Wren or Thomas Wood.

In France, the first public museum was the Louvre Museum in Paris, opened in 1793 during the French Revolution, which enabled for the first time free access to the former French royal collections for people of all stations and status. The fabulous art treasures collected by the French monarchy over centuries were accessible to the public three days each "décade" (the 10-day unit which had replaced the week in the French Republican Calendar). The Conservatoire du muséum national des Arts (National Museum of Arts's Conservatory) was charged with organizing the Louvre as a national public museum and the centerpiece of a planned national museum system. As Napoléon I conquered the great cities of Europe, confiscating art objects as he went, the collections grew and the organizational task became more and more complicated. After Napoleon was defeated in 1815, many of the treasures he had amassed were gradually returned to their owners (and many were not). His plan was never fully realized, but his concept of a museum as an agent of nationalistic fervor had a profound influence throughout Europe.

Chinese and Japanese visitors to Europe were fascinated by the museums they saw there, but had cultural difficulties in grasping their purpose and finding an equivalent Chinese or Japanese term for them. Chinese visitors in the early 19th century named these museums based on what they contained, so defined them as "bone amassing buildings" or "courtyards of treasures" or "painting pavilions" or "curio stores" or "halls of military feats" or "gardens of everything". Japan first encountered Western museum institutions when it participated in Europe's World's Fairs in the 1860s. The British Museum was described by one of their delegates as a 'hakubutsukan', a 'house of extensive things' – this would eventually become accepted as the equivalent word for 'museum' in Japan and China.

Modern history

American museums eventually joined European museums as the world's leading centers for the production of new knowledge in their fields of interest. A period of intense museum building, in both an intellectual and physical sense was realized in the late 19th and early 20th centuries (this is often called "The Museum Period" or "The Museum Age"). While many American museums, both natural history museums and art museums alike, were founded with the intention of focusing on the scientific discoveries and artistic developments in North America, many moved to emulate their European counterparts in certain ways (including the development of Classical collections from ancient Egypt, Greece, Mesopotamia, and Rome). Drawing on Michel Foucault's concept of liberal government, Tony Bennett has suggested the development of more modern 19th-century museums was part of new strategies by Western governments to produce a citizenry that, rather than be directed by coercive or external forces, monitored and regulated its own conduct. To incorporate the masses in this strategy, the private space of museums that previously had been restricted and socially exclusive were made public. As such, objects and artifacts, particularly those related to high culture, became instruments for these "new tasks of social management". Universities became the primary centers for innovative research in the United States well before the start of World War II. Nevertheless, museums to this day contribute new knowledge to their fields and continue to build collections that are useful for both research and display.

Exhibiting human remains of Native Americans.

The late twentieth century witnessed intense debate concerning the repatriation of religious, ethnic, and cultural artifacts housed in museum collections. In the United States, several Native American tribes and advocacy groups have lobbied extensively for the repatriation of sacred objects and the reburial of human remains. In 1990, Congress passed the Native American Graves Protection and Repatriation Act (NAGPRA), which required federal agencies and federally funded institutions to repatriate Native American "cultural items" to culturally affiliate tribes and groups. Similarly, many European museum collections often contain objects and cultural artifacts acquired through imperialism and colonization. Some historians and scholars have criticized the British Museum for its possession of rare antiquities from Egypt, Greece, and the Middle East.

Management

Honours board listing Directors of a Museum.

The roles associated with the management of a museum largely depend on the size of the institution, but every museum has a hierarchy of governance with a Board of Trustees or Board of Directors serving at the top. The Director is next in command and works with the Board to establish and fulfill the museum's mission statement and to ensure that the museum is accountable to the public. Together, the Board and the Director establish a system of governance that is guided by policies that set standards for the institution. Documents that set these standards include an institutional or strategic plan, institutional code of ethics, bylaws, and collections policy. The American Alliance of Museums (AAM) has also formulated a series of standards and best practices that help guide the management of museums.

  • Board of Trustees or Board of directors – The board governs the museum and is responsible for ensuring the museum is financially and ethically sound. They set standards and policies for the museum. Board members are often involved in fundraising aspects of the museum and represent the institution. Some museum use the terms "directors" and "trustees" interchangeably but both are different legal instruments. A board of directors governs a nonprofit corporation, a board of trustees is responsible for governing a charitable trust, foundation, or endowment. In the case of small museums and all volunteer museums, a board may be more hands-on in the day-to-day operations of the museum.
  • Director- The director is the face of the museum to the professional and public community. They communicate closely with the board to guide and govern the museum. They work with the staff to ensure the museum runs smoothly. According to museum professionals Hugh H. Genoways and Lynne M. Ireland, "Administration of the organization requires skill in conflict management, interpersonal relations, budget management and monitoring, and staff supervision and evaluation. Managers must also set legal and ethical standards and maintain involvement in the museum profession."

Various positions within the museum carry out the policies established by the Board and the Director. All museum employees should work together toward the museum's institutional goal. Here is a list of positions commonly found at museums:

  • Curator – Curators are the intellectual drivers behind exhibits. They research the museum's collection and topic of focus, develop exhibition themes, and publish their research aimed at either a public or academic audience. Larger museums have curators in a variety of areas. For example, The Henry Ford has a Curator of Transportation, a Curator of Public Life, a Curator of Decorative Arts, etc. Many art museums have curators dedicated to specific historic periods and geographic regions, such as American art and modern or contemporary art.
  • Collections Management – Collections managers are primarily responsible for the hands-on care, movement, and storage of objects. They are responsible for the accessibility of collections and collections policy.
  • Registrar – Registrars are the primary record keepers of the collection. They insure that objects are properly accessioned, documented, insured, and, when appropriate, loaned. Ethical and legal issues related to the collection are dealt with by registrars. Along with collections managers, they uphold the museum's collections policy.
  • Educator – Museum educators are responsible for educating museum audiences. Their duties can include designing tours and public programs for children and adults, teacher training, developing classroom and continuing education resources, community outreach, and volunteer management. Educators not only work with the public, but also collaborate with other museum staff on exhibition and program development to ensure that exhibits are audience-friendly.
  • Exhibit Designer – Exhibit designers are in charge of the layout and physical installation of exhibits. They create a conceptual design and then bring it to fruition in the physical space.
  • Conservator – Conservators focus on object restoration. More than preserving the object in its present state, they seek to stabilize and repair artifacts to the condition of an earlier era.

Other positions commonly found at museums include: building operator, public programming staff, photographer, librarian, archivist, groundskeeper, volunteer coordinator, preparator, security staff, development officer, membership officer, business officer, gift shop manager, public relations staff, and graphic designer.

At smaller museums, staff members often fulfill multiple roles. Some of these positions are excluded entirely or may be carried out by a contractor when necessary.

Protection

The cultural property stored in museums is threatened in many countries by natural disaster, war, terrorist attacks or other emergencies. To this end, an internationally important aspect is a strong bundling of existing resources and the networking of existing specialist competencies in order to prevent any loss or damage to cultural property or to keep damage as low as possible. International partner for museums is UNESCO and Blue Shield International in accordance with the Hague Convention for the Protection of Cultural Property from 1954 and its 2nd Protocol from 1999. For legal reasons, there are many international collaborations between museums, and the local Blue Shield organizations.

Blue Shield has conducted extensive missions to protect museums and cultural assets in armed conflict, such as 2011 in Egypt and Libya, 2013 in Syria and 2014 in Mali and Iraq. During these operations, the looting of the collection is to be prevented in particular.

Planning

Exhibit planning
 

The design of museums has evolved throughout history. However, museum planning involves planning the actual mission of the museum along with planning the space that the collection of the museum will be housed in. Intentional museum planning has its beginnings with the museum founder and librarian John Cotton Dana. Dana detailed the process of founding the Newark Museum in a series of books in the early 20th century so that other museum founders could plan their museums. Dana suggested that potential founders of museums should form a committee first, and reach out to the community for input as to what the museum should supply or do for the community. According to Dana, museums should be planned according to community's needs:

"The new museum ... does not build on an educational superstition. It examines its community's life first, and then straightway bends its energies to supplying some the material which that community needs, and to making that material's presence widely known, and to presenting it in such a way as to secure it for the maximum of use and the maximum efficiency of that use."

The way that museums are planned and designed vary according to what collections they house, but overall, they adhere to planning a space that is easily accessed by the public and easily displays the chosen artifacts. These elements of planning have their roots with John Cotton Dana, who was perturbed at the historical placement of museums outside of cities, and in areas that were not easily accessed by the public, in gloomy European style buildings.

Questions of accessibility continue to the present day. Many museums strive to make their buildings, programming, ideas, and collections more publicly accessible than in the past. Not every museum is participating in this trend, but that seems to be the trajectory of museums in the twenty-first century with its emphasis on inclusiveness. One pioneering way museums are attempting to make their collections more accessible is with open storage. Most of a museum's collection is typically locked away in a secure location to be preserved, but the result is most people never get to see the vast majority of collections. The Brooklyn Museum's Luce Center for American Art practices this open storage where the public can view items not on display, albeit with minimal interpretation. The practice of open storage is all part of an ongoing debate in the museum field of the role objects play and how accessible they should be.

In terms of modern museums, interpretive museums, as opposed to art museums, have missions reflecting curatorial guidance through the subject matter which now include content in the form of images, audio and visual effects, and interactive exhibits. Museum creation begins with a museum plan, created through a museum planning process. The process involves identifying the museum's vision and the resources, organization and experiences needed to realize this vision. A feasibility study, analysis of comparable facilities, and an interpretive plan are all developed as part of the museum planning process.

Some museum experiences have very few or no artifacts and do not necessarily call themselves museums, and their mission reflects this; the Griffith Observatory in Los Angeles and the National Constitution Center in Philadelphia, being notable examples where there are few artifacts, but strong, memorable stories are told or information is interpreted. In contrast, the United States Holocaust Memorial Museum in Washington, D.C. uses many artifacts in their memorable exhibitions.

Museums are laid out in a specific way for a specific reason and each person who enters the doors of a museum will see its collection completely differently to the person behind them- this is what makes museums fascinating because they are represented differently to each individual.

Financial uses

In recent years, some cities have turned to museums as an avenue for economic development or rejuvenation. This is particularly true in the case of postindustrial cities. Examples of museums fulfilling these economic roles exist around the world. For example, the spectacular Guggenheim Bilbao was built in Bilbao, Spain in a move by the Basque regional government to revitalize the dilapidated old port area of that city. The Basque government agreed to pay $100 million for the construction of the museum, a price tag that caused many Bilbaoans to protest against the project. Nonetheless, the gamble has appeared to pay off financially for the city, with over 1.1 million people visiting the museum in 2015. Key to this is the large demographic of foreign visitors to the museum, with 63% of the visitors residing outside of Spain and thus feeding foreign investment straight into Bilbao. A similar project to that undertaken in Bilbao was also built on the disused shipyards of Belfast, Northern Ireland. Titanic Belfast was built for the same price as the Guggenheim Bilbao (and which was incidentally built by the same architect, Frank Gehry) in time for the 100th anniversary of the Belfast-built ship's maiden voyage in 2012. Initially expecting modest visitor numbers of 425,000 annually, first year visitor numbers reached over 800,000, with almost 60% coming from outside Northern Ireland. In the United States, similar projects include the 81, 000 square foot Taubman Museum of Art in Roanoke, Virginia and The Broad Museum in Los Angeles.

Museums being used as a cultural economic driver by city and local governments has proven to be controversial among museum activists and local populations alike. Public protests have occurred in numerous cities which have tried to employ museums in this way. While most subside if a museum is successful, as happened in Bilbao, others continue especially if a museum struggles to attract visitors. The Taubman Museum of Art is an example of a museum which cost a lot (eventually $66 million) but attained little success, and continues to have a low endowment for its size. Some museum activists also see this method of museum use as a deeply flawed model for such institutions. Steven Conn, one such museum proponent, believes that "to ask museums to solve our political and economic problems is to set them up for inevitable failure and to set us (the visitor) up for inevitable disappointment."

Funding

Museums are facing funding shortages. Funding for museums comes from four major categories, and as of 2009 the breakdown for the United States is as follows: Government support (at all levels) 24.4%, private (charitable) giving 36.5%, earned income 27.6%, and investment income 11.5%. Government funding from the National Endowment for the Arts, the largest museum funder in the United States, decreased by 19.586 million between 2011 and 2015, adjusted for inflation. The average spent per visitor in an art museum in 2016 was $8 between admissions, store and restaurant, where the average expense per visitor was $55. Corporations, which fall into the private giving category, can be a good source of funding to make up the funding gap. The amount corporations currently give to museums accounts for just 5% of total funding. Corporate giving to the arts, however, was set to increase by 3.3% in 2017.

Exhibition design

Most mid-size and large museums employ exhibit design staff for graphic and environmental design projects, including exhibitions. In addition to traditional 2-D and 3-D designers and architects, these staff departments may include audio-visual specialists, software designers, audience research, evaluation specialists, writers, editors, and preparators or art handlers. These staff specialists may also be charged with supervising contract design or production services. The exhibit design process builds on the interpretive plan for an exhibit, determining the most effective, engaging and appropriate methods of communicating a message or telling a story. The process will often mirror the architectural process or schedule, moving from conceptual plan, through schematic design, design development, contract document, fabrication, and installation. Museums of all sizes may also contract the outside services of exhibit fabrication businesses.

Some museum scholars have even begun to question whether museums truly need artifacts at all. Historian Steven Conn provocatively asks this question, suggesting that there are fewer objects in all museums now, as they have been progressively replaced by interactive technology. As educational programming has grown in museums, mass collections of objects have receded in importance. This is not necessarily a negative development. Dorothy Canfield Fisher observed that the reduction in objects has pushed museums to grow from institutions that artlessly showcased their many artifacts (in the style of early cabinets of curiosity) to instead "thinning out" the objects presented "for a general view of any given subject or period, and to put the rest away in archive-storage-rooms, where they could be consulted by students, the only people who really needed to see them". This phenomenon of disappearing objects is especially present in science museums like the Museum of Science and Industry in Chicago, which have a high visitorship of school-aged children who may benefit more from hands-on interactive technology than reading a label beside an artifact.

Types

The National Mall in Washington DC is home to variety of museum types.

There is no definitive standard as to the set types of museums. Additionally, the museum landscape has become so varied, that it may not be sufficient to use traditional categories to comprehend fully the vast variety existing throughout the world. However, it may be useful to categorize museums in different ways under multiple perspectives. Museums can vary based on size, from large institutions, to very small institutions focusing on a specific subjects, such as a specific location, a notable person, or a given period of time. Museums also can be based on the main source of funding: central or federal government, provinces, regions, universities; towns and communities; other subsidised; nonsubsidised and private.

It may sometimes be useful to distinguish between diachronic museums - those that interpret the way in which its subject matter has developed and evolved through time (examples: Lower East Side Tenement Museum and Diachronic Museum of Larissa), and synchronic museums - those that interpret the way in which its subject matter exists at one point in time (examples:The Anne Frank House and Colonial Williamsburg). According to University of Florida's Professor Eric Kilgerman, "While a museum in which a particular narrative unfolds within its halls is diachronic, those museums that limit their space to a single experience are called synchronic."

In her book, Civilizing the Museum, author Elaine Heumann Gurian proposes that there are five categories of museums based on intention not content. Object Centered, Narrative, Client Centered, Community Centered, and National.

Museums can also be categorized into major groups by the type of collections they display, to include: fine arts, applied arts, craft, archaeology, anthropology and ethnology, biography, history, cultural history, science, technology, children's museums, natural history, botanical and zoological gardens. Within these categories, many museums specialize further, e.g. museums of modern art, folk art, local history, military history, aviation history, philately, agriculture, or geology. The size of a museum's collection typically determines the museum's size, whereas its collection reflects the type of museum it is. Many museums normally display a "permanent collection" of important selected objects in its area of specialization, and may periodically display "special collections" on a temporary basis.

Major museum types

The following is a list to give an idea of the major museum types. While comprehensive it is not a definitive list.

Legal framework of museums

Public vs. private museums

Private museums are organized by individuals and managed by a board and museum officers, but public museums are created and managed by federal, state, or local governments. A government can charter a museum through legislative action but the museum can still be private as it is not part of the government. The distinction regulates the ownership and legal accountability for the care of the collections.

Non-profit vs. for-profit museums

Nonprofit means that an organization is classified as a charitable corporation and is exempt from paying most taxes and the money the organization earns is invested in the organization itself. Money made by a private, for-profit museum is paid to the museum's owners or shareholders.

The nonprofit museum has a fiduciary responsibility in regards to the public, in essence the museum holds its collections and administers it for the benefit of the public. Collections of for-profit museums are legally corporate assets the museum administers for the benefit of the owners or shareholders.

Museums run by trusts vs. corporations

A trust is a legal instrument where trustees manage the trust's assets for the benefit of the museum following the specific wishes of the donor. This provides tax benefits for the donor, and also allows the donor to have control over how assets are distributed.

Corporations are legal entities and may acquire property in a way similar to how an individual can own property. Museums under incorporation are usually organized by a community or group of individuals. While a board of director's loyalty is to the corporation, a board of trustee's loyalty has to be loyal to the intention of the trust. The ramification is that a trust is far less flexible than a corporation.

Current challenges facing museums

Sustainability and climate change

Increasingly museums have been responded to the ongoing climate crisis through enacting sustainable museum practices, and exhibitions highlighting the issues surrounding climate change and the Anthropocene.

Decolonization of museums

Moai figure at the British Museum

During the beginning of the 21st century, a growing global movement for the decolonization of museums has arisen. Proponents of this movement argue that 'museums are a box of things' and do not represent complete stories; instead they show biased narratives based on ideologies, in which certain stories are intentionally disregarded. Through this, people are encouraging others to consider this missing perspective, when looking at museum collections, as every object viewed in such environments was placed by an individual to represent a certain viewpoint, be it historical or cultural.

The 2018 report on the restitution of African cultural heritage is a prominent example regarding the decolonization of museums and other collections in France and the claims of African countries to regain artifacts illegally taken from their original cultural settings.

Since 1868, several monolithic human figures known as Moai have been removed from Easter Island and put in display in major Western museums such as the National Museum of Natural History, the British Museum, the Louvre and the Royal Museums of Art and History. Several demands have been made by Easter Island residents for the return of the Moai. The figures are seen as ancestors and family or the soul by the Rapa Nui and hold deep cultural value to their people. Other examples include the Gweagal Shield, thought to be a very significant shield taken from Botany Bay in April 1770 or the Parthenon marble sculptures, which were taken from Greece by Lord Elgin in 1805. Successive Greek governments have unsuccessfully petitioned for the return of the Parthenon marbles. Another example among many others is the so-called Montezuma's headdress in the Museum of Ethnology, Vienna, which is a source of dispute between Austria and Mexico.

Laura Van Broekhoven, director of the Pitt Rivers Museum in Oxford, United Kingdom, stated in 2020 that "ethnographic museums should redress their coloniality. They should be a pluriverse that shows the rich diversity of ways of being and knowing, not centering whiteness as the only way of being. Museums ought to allow for everyone to understand each other better."

Environmental sensitivity

From Wikipedia, the free encyclopedia

Environmental sensitivity describes the ability of an individual to perceive and process information about their environment. It is a fundamental and basic trait found in many organisms and is crucial because it enables an individual to adapt to different environmental conditions. Levels of Environmental Sensitivity often vary considerably from individual to individual, with some being more and others less sensitive to the same conditions. Such differences have been observed across many species such as pumpkinseed fish, zebra finches, mice, non-human primates and humans, indicating that there is a biological basis to differences in sensitivity. Several psychological theories have been developed to explore and explain the differences and recently, these theories have been integrated by Prof Michael Pluess into a broader framework under the umbrella term of Environmental Sensitivity.

Theoretical background

The concept of Environmental Sensitivity integrates multiple theories on how people respond to negative and positive experiences. These include the frameworks of Diathesis-stress model and Vantage Sensitivity, as well as the three leading theories on more general sensitivity: Differential Susceptibility, Biological Sensitivity to Context, and Sensory processing sensitivity (see Figure 1 for an illustration of the different models). These will be described briefly in turn, before presenting the integrative theory of Environmental Sensitivity in more detail.

Figure 1. Illustration of the different models describing individual differences in Environmental Sensitivity: Diathesis-Stress (1.1) describes variability in response to adverse exposures, and Vantage Sensitivity (1.2) variability in response to supportive exposures, whereas the remaining three models Differential Susceptibility (1.3), Biological Sensitivity to Context (1.4), and Sensory Processing Sensitivity (1.5) describe individual differences in response to both negative and positive experiences. Consequently, Models 1.3, 1.4, and 1.5 reflect the combination of Models 1.1 and 1.2.

Diathesis-Stress

According to the long-standing Diathesis-stress model, people differ in their response to adverse experiences and environments, with some individuals more negatively affected by environmental stressors than others. The model proposes that such differences in response result from the presence of "vulnerability" factors, which include psychological (e.g., impulsive personality), physiological (e.g., high physiological reactivity) and genetic factors (e.g., genetic variation in the serotonin transporter [5-HTTLPR short allele]). In other words, the model suggests that individuals carrying certain vulnerability factors are at greater risk of developing problems when exposed to adverse environments. While the Diathesis-stress model is helpful in understanding differences in response to negative stressors, it does not consider or describe differences in response to positive experiences.

Vantage Sensitivity

The Vantage Sensitivity framework was developed in 2013 by Michael Pluess and Jay Belsky to describe individual differences in response to positive experiences and environments. While some people appear to benefit particularly strongly from positive experiences (e.g., positive parenting, supportive relationships, psychological interventions), others appear to benefit less. Although a relatively new concept, a growing number of studies provides evidence to support the framework. While the Vantage Sensitivity framework considers individual differences in response to positive experiences, it does not make predictions about the response to negative experiences.

Differential Susceptibility

Differential susceptibility, proposed by Jay Belsky, brings the differential responses to both positive and negative experiences together in one single model. Grounded in evolutionary theory, Belsky and colleagues sought to understand why and how children differ so fundamentally in their developmental response to external influences, with some being more and others less susceptible. Importantly, the theory finds that more susceptible individuals are not only more negatively affected by adverse experiences (as described in the Diathesis-stress model) but also particularly positively affected by the presence of favourable conditions (as described in the Vantage Sensitivity model). According to empirical studies, Differential Susceptibility is associated with various genetic, physiological and psychological factors, some of which are described below (see Empirical Evidence). Although early research suggested that differences in individuals' susceptibility are rooted in genetic factors, more recent research has shown that susceptibility is also influenced by prenatal and early postnatal environmental factors.

Biological Sensitivity to Context

The theory of Biological Sensitivity to Context by Tom Boyce and Bruce Ellis is based on evolutionary thinking and proposes that an individual's sensitivity to the environment is shaped by the quality of early life experiences. For example, particularly negative or especially positive childhood environments are understood to predict greater physiological reactivity later in life. In contrast, sensitivity is expected to be lowest for individuals with childhood environments that were neither extremely beneficial nor extremely adverse.

Sensory Processing Sensitivity

Sensory processing sensitivity (SPS) theory by Elaine N. Aron and Arthur Aron proposes that sensitivity is a stable human trait characterized by greater awareness of sensory stimulation, behavioural inhibition, deeper cognitive processing of environmental stimuli, and higher emotional and physiological reactivity. According to this theory, approximately 20% of people fall into the category of a Highly Sensitive Person (HSP), in contrast to the remaining 80% who are considered less sensitive. Furthermore, the theory suggests that the sensitivity trait is adaptive from an evolutionary perspective, and regards differences in sensitivity as genetically determined and expressed via a more sensitive central nervous system.

Environmental Sensitivity

The broad theory of Environmental Sensitivity. integrates all of the listed frameworks and proposes that although all people are sensitive to their environment, some individuals tend to be more sensitive than others. Furthermore, the theory of Environmental Sensitivity suggests that people vary in their sensitivity to the environment due to differences in their ability to perceive and process information about the environment. In other words, more sensitive individuals are characterised by heightened perception as well as deeper processing of external information due to neurobiological differences in the central nervous system, which are influenced by genetic as well as environmental factors. The integrative perspective of Environmental Sensitivity further proposes that whilst some individuals are more sensitive to both negative and positive experiences, others may be particularly vulnerable to adverse experiences (but not very sensitive to positive ones), whilst some may be especially responsive to positive exposure (but not vulnerable to negative ones).

Empirical evidence for individual differences in sensitivity

Differences in sensitivity have been studied in relation to a wide range of sensitivity markers, such as genetic, physiological and psychological ones. These are now discussed in turn.

Genetic markers of sensitivity

A growing number of studies provide empirical evidence to support individual differences in sensitivity at the genetic level. These include traditional Gene-environment interaction studies featuring Candidate genes, as well as more recent genome-wide approaches. As an example for the latter, Keers et al created a polygenic score for Environmental Sensitivity based on about 25,000 gene variants across the genome and then tested whether children at the extremes of this spectrum of genetic sensitivity differed in their response to the parenting quality they received. According to the results, children with high genetic sensitivity were more likely to develop emotional problems when experiencing negative parenting but also less likely to develop problems when parenting was positive. On the other hand, children with low genetic sensitivity were not as impacted by the experience of negative or positive parenting, and did not differ from each other in emotional problems based on parenting quality. Hence, this study provides important evidence that genetic sensitivity, measured across the genome, predicts children's sensitivity to both negative and positive environmental influences.

Physiological markers of sensitivity

Several empirical studies have reported differences in sensitivity to the environment in relation to individuals' physiological reactivity. Higher reactivity generally appears to reflect greater sensitivity. For example, research has shown that children with a higher physiological response to stress (indicated by the hormone cortisol) are more strongly affected by their family's financial situation. More specifically, a high cortisol response in children was associated with more positive cognitive development when family income was high, but with reduced cognitive development when family income was low. In contrast, family income was less relevant for the cognitive development of children who displayed low physiological reactivity (i.e., a low cortisol response). Similarly, adolescents with high cortisol levels have been found to report more stress when experiencing school-related challenges but also the lowest stress in less demanding situations, whereas adolescents with lower cortisol levels were generally less affected by either low or high school-related challenges 

Psychological markers of sensitivity

The majority of evidence for individual differences in sensitivity due to psychological markers of sensitivity is based on studies that investigate the interplay between infant temperament and parenting during childhood. Generally, higher fearfulness, fussiness, and negative emotionality in infancy have been associated with greater sensitivity to parenting quality. According to a large meta-analysis which summarises the findings from 84 individual studies, children that are characterised by a more sensitive temperament were more strongly affected by the parenting they receive. More specifically, sensitive children were more likely to develop problems when experiencing harsh and punitive parenting but also least likely to have problems when they were raised in emotionally warm and caring environments. Less sensitive children, on the other hand, did not differ much from each other whether they received more negative or more positive parenting.

Determinants of Environmental Sensitivity

An individual's level of Environmental Sensitivity is the result of a complex interplay between genes and environmental influences across development. Empirical studies suggest that genetic influences are important for the development of the trait, but only about 50% of the differences in sensitivity between people can be explained by genetic factors, with the remaining 50% being shaped by environmental influences (see Figure 2). Furthermore, the genetic component of sensitivity is most likely made up by a large number of genetic variants across the whole genome, each making a small contribution, rather than a few specific genes. Importantly, although sensitivity has a substantial genetic basis, it may be the quality of the environment when growing up that shapes this genetic potential for sensitivity further. For example, those carrying a larger number of sensitivity genes may develop a sensitivity that is more geared towards threat when growing up in a challenging or adverse environment (i.e., vulnerability as described in the Diathesis-Stress model), whereas those growing up in a predominately supportive and secure context may develop heightened sensitivity towards positive aspects of the environment (i.e., Vantage Sensitivity). Similarly, those that experienced similar levels of both negative and positive exposures during childhood may develop equal levels of sensitivity to negative and positive experiences (i.e., Differential Susceptibility).

Underlying biological mechanisms of Environmental Sensitivity

Environmental Sensitivity proposes that sensitivity is driven primarily by a heightened sensitivity of the central nervous system (i.e., neurosensitivity)(see Figure 2 for an illustration of the neurosensitivity hypothesis). In other words, sensitive people have more sensitive brains, which perceive information about the environment more readily and process such information in greater depth. This likely involves specific structural and functional aspects of various brain regions, including the amygdala and hippocampus. These characteristics of the brain are then responsible for the typical experiences and behaviours associated with high sensitivity, such as experiencing emotions more strongly, responding more strongly to stressful situations or change, having a higher physiological reactivity, processing experiences in depth by thinking a lot about them, appreciating beauty, and picking up on subtle details.

Figure 2. Illustration of the neurosensitivity hypothesis. Direct and interactive effects between sensitivity genes and environmental factors shape the sensitivity of the central nervous system. Heightened central nervous system sensitivity is then manifested in psychological/behavioral and physiological responsivity.

Measurement of Environmental Sensitivity

In the last few decades, researchers have identified a wide range of individual characteristics that reflect or are associated with sensitivity to environmental influences. These include specific aspects of child temperament (e.g., difficult temperament, negative emotionality, and impulsivity), physiological reactivity (e.g., high cortisol reactivity) and various genetic variants that can be combined into a polygenic score of sensitivity. However, although these characteristics are important and capture some aspects of sensitivity they cannot be considered precise measures in themselves. Given that sensitivity is a complex trait, similar to other personality dimensions, it is more helpful to measure sensitivity with questionnaires, interviews, or behavioural observations that focus on the assessment of the typical behaviours and experiences that reflect the core attributes of sensitivity (i.e., perception and processing).

Questionnaires

A series of such sensitivity scales have been developed and are briefly described below.

The Highly Sensitive Person Scale(HSP)

The Highly Sensitive Person Scale (HSP) is a 27-item self-report measure designed to assess Environmental Sensitivity in adults. Items are rated on a 7-point Likert scale from 1 = "Not at All" to 7 = "Extremely". Items search for a tendency to be easily overwhelmed by external and internal stimuli (e.g. "Do you find it unpleasant to have a lot going on at once?"), greater aesthetic awareness (e.g. "Do you seem to be aware of subtleties in your environment?"), and unpleasant sensory arousal to external stimuli (e.g. "Are you bothered by intense stimuli, like loud noises or chaotic scenes?"). The scale exists also in a brief version with 12 items.

Highly Sensitive Child (HSC) scale

The Highly Sensitive Child (HSC) scale is a 12-item self-report measure that is based on the adult HSP scale and has been designed to assess Environmental Sensitivity in children and adolescents between the ages of 8 and 18 years. Items included in the HSC scale are rated on a 7-point Likert scale from 1 = "Not at All" to 7 = "Extremely". Items are designed to capture different facets of sensitivity, such as the tendency to become mentally overwhelmed by both internal and external stimuli, greater appreciation of beauty, and overstimulation when experiencing intense sensory inputs. The HSC scale also exists in parent-rated version where parents can rate their child.

Observational measures

The Highly Sensitive Child – Rating System (HSC – RS) is an observational measure designed to assess Environmental Sensitivity in three-year-old children. Children's responses in a series of standardised situations are observed and rated by trained experts.

Sensitivity groups

Orchids, tulips and dandelions

Initially, several psychological theories of sensitivity differentiated between two basic groups of people: those that are highly sensitive and those that are not. The assumption was that about 20% of the general population are characterised by high sensitivity. Such individuals have been compared to the "Orchid", a plant that requires optimal conditions and care in order to flourish. In contrast, the remaining 80%, thought to be less sensitive, were compared to the "Dandelion", a plant that is robust and grows under many different conditions, to reflect this group's tendency to be less affected by the quality of the environment. More recently, this two-group hypothesis has been challenged by several studies reporting that sensitivity is more likely a common trait that is best considered a spectrum from low to high. This means that all people are sensitive but to different degrees. These studies found that people fall into three, rather than two, distinct sensitivity groups along a spectrum of sensitivity from low (30% of the population), to medium (40%), to high (30%). According to this research, the 40% that fall into the middle of the sensitivity continuum are referred to as "Tulips", a plant that is more delicate than the "Dandelion" but less fragile then the "Orchid".

Voyager Golden Record

From Wikipedia, the free encyclopedia

The Voyager Golden Record
 
Cover of the Voyager Golden Record
 
The golden record's location on Voyager (middle-bottom-left)

The Voyager Golden Records are two phonograph records that were included aboard both Voyager spacecraft launched in 1977. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form who may find them. The records are a sort of time capsule.

Although neither Voyager spacecraft is heading toward any particular star, Voyager 1 will pass within 1.6 light-years' distance of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years.

Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space, but the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet."

Background

The Voyager 1 probe is currently the farthest human-made object from Earth. Both Voyager 1 and Voyager 2 have reached interstellar space, the region between stars where the galactic plasma is present. Like their predecessors Pioneer 10 and 11, which featured a simple plaque, both Voyager 1 and Voyager 2 were launched by NASA with a message aboard—a kind of time capsule, intended to communicate to extraterrestrials a story of the world of humans on Earth.

This is a present from a small, distant world, a token of our sounds, our science, our images, our music, our thoughts and our feelings. We are attempting to survive our time so we may live into yours.

Contents

The contents of the record were selected for NASA by a committee chaired by Carl Sagan of Cornell University. The selection of content for the record took almost a year. Sagan and his associates assembled 115 images and a variety of natural sounds, such as those made by surf, wind, thunder and animals (including the songs of birds and whales). To this they added audio content to represent humanity: spoken greetings in 55 ancient and modern languages, including a spoken greeting in English by U.N. Secretary-General Kurt Waldheim and a greeting by Sagan's six-year-old son, Nick; other human sounds, like footsteps and laughter (Sagan's); the inspirational message Per aspera ad astra in Morse code; and musical selections from different cultures and eras. The record also includes a printed message from U.S. president Jimmy Carter.

The collection of images includes many photographs and diagrams both in black and white, and color. The first images are of scientific interest, showing mathematical and physical quantities, the Solar System and its planets, DNA, and human anatomy and reproduction. Care was taken to include not only pictures of humanity, but also some of animals, insects, plants and landscapes. Images of humanity depict a broad range of cultures. These images show food, architecture, and humans in portraits as well as going about their day-to-day lives. Many pictures are annotated with one or more indications of scales of time, size, or mass. Some images contain indications of chemical composition. All measures used on the pictures are defined in the first few images using physical references that are likely to be consistent anywhere in the universe.

The musical selection is also varied, featuring works by composers such as J.S. Bach (interpreted by Glenn Gould), Mozart, Beethoven (played by the Budapest String Quartet), and Stravinsky. The disc also includes music by Guan Pinghu, Blind Willie Johnson, Chuck Berry, Kesarbai Kerkar, Valya Balkanska, and electronic composer Laurie Spiegel, as well as Azerbaijani folk music (Mugham) by oboe player Kamil Jalilov. The inclusion of Berry's "Johnny B. Goode" was controversial, with some claiming that rock music was "adolescent", to which Sagan replied, "There are a lot of adolescents on the planet." The selection of music for the record was completed by a team composed of Carl Sagan as project director, Linda Salzman Sagan, Frank Drake, Alan Lomax, Ann Druyan as creative director, artist Jon Lomberg, ethnomusicologist Robert E. Brown, Timothy Ferris as producer, and Jimmy Iovine as sound engineer. It also included the sounds of humpbacked whales from the 1970 album by Roger Payne, Songs of the Humpback Whale.

The Golden Record also carries an hour-long recording of the brainwaves of Ann Druyan. During the recording of the brainwaves, Druyan thought of many topics, including Earth's history, civilizations and the problems they face, and what it was like to fall in love.

After NASA had received criticism over the nudity on the Pioneer plaque (line drawings of a naked man and woman), the agency chose not to allow Sagan and his colleagues to include a photograph of a nude man and woman on the record. Instead, only a silhouette of the couple was included. However, the record does contain "Diagram of vertebrate evolution", by Jon Lomberg, with drawings of an anatomically correct naked male and naked female, showing external organs. The person waving on the diagram was also changed: on the Pioneer plaque, the man is waving, while on the "Vertebrate evolution" image, the woman is waving.

The pulsar map and hydrogen molecule diagram are shared in common with the Pioneer plaque.

The 115 images are encoded in analogue form and composed of 512 vertical lines. The remainder of the record is audio, designed to be played at 16+23 revolutions per minute.

Jimmy Iovine, who was still early in his career as a music producer, served as sound engineer for the project at the recommendation of John Lennon, who was contacted to contribute but was unable to take part.

Sagan's team wanted to include the Beatles song "Here Comes the Sun" on the record, but the record company EMI, which held the copyrights, declined. In the 1978 book Murmurs of Earth, the failure to secure permission for the song is cited as one of the legal challenges faced by the team compiling the Voyager Golden Record. In the book, Sagan said that the Beatles favoured the idea, but "[they] did not own the copyright, and the legal status of the piece seemed too murky to risk." When asked about the obstacle presented by EMI with regard to "Here Comes the Sun", despite the artists' wishes, Ann Druyan said in 2015: "Yeah, that was one of those cases of having to see the tragedy of our planet. Here's a chance to send a piece of music into the distant future and distant time, and to give it this kind of immortality, and they're worried about money ... we got this telegram [from EMI] saying that it will be $50,000 per record for two records, and the entire Voyager record cost $18,000 to produce." However, this was denied in 2017 by Timothy Ferris; in his recollection, "Here Comes the Sun" was never considered for inclusion.

In July 2015, NASA uploaded the audio contents of the record to the audio streaming service SoundCloud.

Playback

Explanation of the Voyager record cover diagram, as provided by NASA

In the upper left-hand corner of the record cover is a drawing of the phonograph record and the stylus carried with it. The stylus is in the correct position to play the record from the beginning. Written around it in binary notation is the correct time of one rotation of the record, 3.6 seconds, expressed in time units of 0.70 billionths of a second, the time period associated with a fundamental transition of the hydrogen atom. The drawing indicates that the record should be played from the outside in. Below this drawing is a side view of the record and stylus, with a binary number giving the time to play one side of the record—about an hour (more precisely, between 53 and 54 minutes).

The information in the upper right-hand portion of the cover is designed to show how pictures are to be constructed from the recorded signals. The top drawing shows the typical signal that occurs at the start of a picture. The picture is made from this signal, which traces the picture as a series of vertical lines, similar to analog television (in which the picture is a series of horizontal lines). Picture lines 1, 2 and 3 are noted in binary numbers, and the duration of one of the "picture lines," about 8 milliseconds, is noted. The drawing immediately below shows how these lines are to be drawn vertically, with staggered "interlace" to give the correct picture rendition. Immediately below this is a drawing of an entire picture raster, showing that there are 512 (29) vertical lines in a complete picture. Immediately below this is a replica of the first picture on the record to permit the recipients to verify that they are decoding the signals correctly. A circle was used in this picture to ensure that the recipients use the correct ratio of horizontal to vertical height in picture reconstruction. Color images were represented by three images in sequence, one each for red, green, and blue components of the image. A color image of the spectrum of the sun was included for calibration purposes.

The drawing in the lower left-hand corner of the cover is the pulsar map previously sent as part of the plaques on Pioneers 10 and 11. It shows the location of the Solar System with respect to 14 pulsars, whose precise periods are given. The drawing containing two circles in the lower right-hand corner is a drawing of the hydrogen atom in its two lowest states, with a connecting line and digit 1 to indicate that the time interval associated with the transition from one state to the other is to be used as the fundamental time scale, both for the time given on the cover and in the decoded pictures.

Manufacturing

Gold plating at the James G. Lee Record Processing center in Gardena, California (left), and preparation for the record's packaging before the launch of Voyager 2

Blank records were provided by the Pyral S.A. of Créteil, France. CBS Records contracted the JVC Cutting Center in Boulder, Colorado to cut the lacquer masters which were then sent to the James G. Lee record-processing center in Gardena, California to cut and gold-plate eight Voyager records. After the records were plated they were mounted in aluminum containers and delivered to JPL.

The record is constructed of gold-plated copper and is 12 inches (30 cm) in diameter. The record's cover is aluminum and electroplated upon it is an ultra-pure sample of the isotope uranium-238. Uranium-238 has a half-life of 4.468 billion years. It is possible (e.g., via mass spectrometry) that a civilization that encounters the record will be able to use the ratio of remaining uranium to the other elements to determine the age of the record.

The records also had the inscription "To the makers of music – all worlds, all times" hand-etched on its surface. The inscription was located in the "takeout grooves", an area of the record between the label and playable surface. Since this was not in the original specifications, the record was initially rejected, to be replaced with a blank disc. Sagan later convinced the administrator to include the record as is.

Journey

The golden record is attached to the spacecraft.

Voyager 1 was launched in 1977, passed the orbit of Pluto in 1990, and left the Solar System (in the sense of passing the termination shock) in November 2004. It is now in the Kuiper belt. In about 40,000 years, it and Voyager 2 will each come to within about 1.8 light-years of two separate stars: Voyager 1 will have approached star Gliese 445, located in the constellation Camelopardalis, and Voyager 2 will have approached star Ross 248, located in the constellation of Andromeda.

In March 2012, Voyager 1 was over 17.9 billion km from the Sun and traveling at a speed of 3.6 AU per year (approximately 61,000 km/h (38,000 mph)), while Voyager 2 was over 14.7 billion km away and moving at about 3.3 AU per year (approximately 56,000 km/h (35,000 mph)).

In May 2005, it was reported that Voyager 1 had entered the heliosheath, the region beyond the termination shock. The termination shock is where the solar wind, a thin stream of electrically charged gas blowing continuously outward from the Sun, is slowed by pressure from gas between the stars. At the termination shock, the solar wind slows abruptly from its average speed of 300–700 km/s (670,000–1,570,000 mph) and becomes denser and hotter.

Of the eleven instruments carried on Voyager 1, four are still operational and continue to send back data. It is expected that there will be insufficient energy to power any of the instruments beyond 2025.

On September 12, 2013, NASA announced that Voyager 1 had left the heliosheath and entered interstellar space, although it still remains within the Sun's gravitational sphere of influence.

Depictions in culture

A copy of the record on display at the Udvar-Hazy Center in Washington Dulles International Airport

Several works of science fiction, such as the 1979 film Star Trek: The Motion Picture, the 1984 film Starman, the 2000 film Battlefield Earth, and the animated television show Beast Wars feature extraterrestrial intelligences discovering the record and turning their attention to Earth as a result.

In a Saturday Night Live segment ("Next Week in Review") in episode 64 of the show's third season (originally aired 1978), Steve Martin's character, a psychic named Cocuwa, announced that extraterrestrials had responded to the record with the four words "Send more Chuck Berry".

The recording is a major plot piece of "Little Green Men", a season 2 episode of The X-Files.

On Star Trek: Voyager, the Greetings from Earth on the golden record are sent to Voyager by Rain Robinson in Season 3, Episode 8 "Future's End".

In the 2004 episode of The West Wing, "The Warfare of Genghis Khan" (season 5 episode 13), the golden record is referenced. In particular, Josh Lyman (played by Bradley Whitford), notes the inclusion of Blind Willie Johnson's "Dark Was the Night, Cold Was the Ground" on the record as inspirational.

It was also referenced in the 2005 animation known as Fafner in the Azure as being one of the objects that the aliens discover.

In 2014, the podcast The Truth produced an episode titled "Voyager Found", where the Voyager crash-lands on the property of Dawn and Tad, an alien couple, who decide to play the record.

In 2014, composer Dario Marianelli wrote a Voyager Concerto for Violin and Orchestra, which was premiered in Brisbane, Australia in November that year by the Queensland Symphony Orchestra (QSO), and in Stockholm the following April (2015), by the Swedish Radio Orchestra. The QSO, with British violinist Jack Liebeck, performed the piece over several concerts at the Queensland Performing Arts Centre; each performance was preceded by a lecture by physicist professor Brian Cox, who talked at length about NASA's Voyager Mission, and introduced the concerto. The 30-minute piece, in one single movement, depicts the journey of the Voyager through the Solar System, using as references some of the music that is on board each probe, on the Golden Record.

The Voyager probes are a visitable landmark in the 2014 space-trading/simulation game Elite: Dangerous. It is possible to see the golden record on the probe models.

English folk artist Jim Moray released the song "Sounds of Earth" on his 2016 album Upcetera. Named after the golden record, it tells the story of the project with a particular focus on the relationship between Carl Sagan and Ann Druyan.

Grace Petrie, an English songwriter and folk singer, released a track by the name of "The Golden Record" on her 2017 album Heart First Aid Kit, which is a love song based upon the story of Carl Sagan and Ann Druyan, referencing the additions made to the record intended to depict the sound of human beings in love.

The 2017 documentary The Farthest, directed by Emer Reynolds, features those who worked on the Golden Record and Voyager missions including Frank Drake, Timothy Ferris, and Nick Sagan.

Troop Zero, a 2019 American comedy-drama film, inspired by Alibar's 2010 play Christmas and Jubilee Behold The Meteor Shower, focuses on the story of a scout group competing to have their voices included on the Golden Record.

The 2019 death metal album Death Atlas by Cattle Decapitation opens with a track that samples the greetings on the golden record in their entirety.

The 2020 indie rock album Possession by Joywave features sounds from the record.

Publications

Most of the images used on the record (reproduced in black and white), together with information about its compilation, can be found in the 1978 book Murmurs of Earth: The Voyager Interstellar Record by Carl Sagan, F. D. Drake, Ann Druyan, Timothy Ferris, Jon Lomberg, and Linda Salzman. A CD-ROM version was issued by Warner New Media in 1992. Author Ann Druyan, who later married Carl Sagan, wrote about the Voyager Record in the epilogue of Sagan's final book Billions and Billions (1997).

To celebrate the 40th anniversary of the record, Ozma Records launched a Kickstarter project to release the record contents in LP format as part of a box set also containing a hardcover book, turntable slipmat, and art print. The Kickstarter was successfully funded with over $1.4 million raised. Ozma Records then produced another edition of the three-disc LP vinyl record box set that also includes the audio content of the Golden Record, softcover book containing the images encoded on the record, images sent back by Voyager, commentary from Ferris, art print, turntable slipmat, and a collector's box. This edition was released in February 2018 along with a 2xCD-Book edition. In January 2018, Ozma Records' "Voyager Golden Record; 40th Anniversary Edition" won a Grammy Award for best boxed or limited-edition package.
