Islamic attitudes towards science

Muslim scholars have developed a spectrum of viewpoints on science within the context of Islam. Scientists of medieval Muslim civilization (e.g. Ibn al-Haytham) contributed to the new discoveries in science. From the eighth to fifteenth century, Muslim mathematicians and astronomers furthered the development of mathematics. Concerns have been raised about the lack of scientific literacy in parts of the modern Muslim world.

Islamic scientific achievements encompassed a wide range of subject areas, especially medicine, mathematics, astronomy, agriculture as well as physics, economics, engineering and optics.

Aside from these contributions, some Muslim writers have made claims that the Quran made prescient statements about scientific phenomena as regards the structure of the embryo, the Solar System, and the development of the universe.

Terminology

According to Toby Huff, there is no true word for science in Arabic as commonly defined in English and other languages. In Arabic, "science" can simply mean different forms of knowledge. This view has been criticized by other scholars. For example, according to Muzaffar Iqbal, Huff's framework of inquiry "is based on the synthetic model of Robert Merton who had made no use of any Islamic sources or concepts dealing with the theory of knowledge or social organization". Each branch of science has its own name, but all branches of science have a common prefix, ilm. For example, physics is more literally translated from Arabic as "the science of nature", علم الطبيعة ‘ilm aṭ-ṭabī‘a; arithmetic as the "science of accounts" علم الحساب ilm al-hisab. The religious study of Islam (through Islamic sciences like Quranic exegesis, hadith studies, etc.) is called العلم الديني "science of religion" (al-ilm ad-dinniy), using the same word for science as "the science of nature". According to the Hans Wehr Dictionary of Arabic, while علم’ ilm is defined as "knowledge, learning, lore," etc. the word for "science" is the plural form علوم’ ulūm. (So, for example, كلية العلوم kullīyat al-‘ulūm, the Faculty of Science of the Egyptian University, is literally "the Faculty of Sciences ...")

History

Classical science in the Muslim world

Work in the observatorium of Taqi al-Din

One of the earliest accounts of the use of science in the Islamic world is during the eighth and sixteenth centuries, known as the Islamic Golden Age. It is also known as "Arabic science" because of the majority of texts that were translated from Greek into Arabic. The mass translation movement, that occurred in the ninth century allowed for the integration of science into the Islamic world. The teachings from the Greeks were now translated and their scientific knowledge was now passed on to the Arab world. Despite these conditions, not all scientists during this period were Muslim or Arab, as there were a number of notable non-Arab scientists (most notably Persians), as well as some non-Muslim scientists, who contributed to scientific studies in the Muslim world.

A number of modern scholars such as Fielding H. Garrison, Sultan Bashir Mahmood, Hossein Nasr consider modern science and the scientific method to have been greatly inspired by Muslim scientists who introduced a modern empirical, experimental and quantitative approach to scientific inquiry. Certain advances made by medieval Muslim astronomers, geographers and mathematicians were motivated by problems presented in Islamic scripture, such as Al-Khwarizmi's (c. 780–850) development of algebra in order to solve the Islamic inheritance laws, and developments in astronomy, geography, spherical geometry and spherical trigonometry in order to determine the direction of the Qibla, the times of Salah prayers, and the dates of the Islamic calendar. These new studies of math and science would allow for the Islamic world to get ahead of the rest of the world. ‘With these inspiration at work, Muslim mathematicians and astronomers contributed significantly to the development to just about every domain of mathematics between the eight and fifteenth centuries"

The increased use of dissection in Islamic medicine during the 12th and 13th centuries was influenced by the writings of the Islamic theologian, Al-Ghazali, who encouraged the study of anatomy and use of dissections as a method of gaining knowledge of God's creation. In al-Bukhari's and Muslim's collection of sahih hadith it is said: "There is no disease that God has created, except that He also has created its treatment." (Bukhari 7-71:582). This culminated in the work of Ibn al-Nafis (1213–1288), who discovered the pulmonary circulation in 1242 and used his discovery as evidence for the orthodox Islamic doctrine of bodily resurrection. Ibn al-Nafis also used Islamic scripture as justification for his rejection of wine as self-medication. Criticisms against alchemy and astrology were also motivated by religion, as orthodox Islamic theologians viewed the beliefs of alchemists and astrologists as being superstitious.

Fakhr al-Din al-Razi (1149–1209), in dealing with his conception of physics and the physical world in his Matalib, discusses Islamic cosmology, criticizes the Aristotelian notion of the Earth's centrality within the universe, and "explores the notion of the existence of a multiverse in the context of his commentary," based on the Quranic verse, "All praise belongs to God, Lord of the Worlds." He raises the question of whether the term "worlds" in this verse refers to "multiple worlds within this single universe or cosmos, or to many other universes or a multiverse beyond this known universe." On the basis of this verse, he argues that God has created more than "a thousand thousand worlds (alfa alfi 'awalim) beyond this world such that each one of those worlds be bigger and more massive than this world as well as having the like of what this world has." Ali Kuşçu's (1403–1474) support for the Earth's rotation and his rejection of Aristotelian cosmology (which advocates a stationary Earth) was motivated by religious opposition to Aristotle by orthodox Islamic theologians, such as Al-Ghazali.

According to many historians, science in the Muslim civilization flourished during the Middle Ages, but began declining at some time around the 14th to 16th centuries. At least some scholars blame this on the "rise of a clerical faction which froze this same science and withered its progress." Examples of conflicts with prevailing interpretations of Islam and science – or at least the fruits of science – thereafter include the demolition of Taqi al-Din's great Constantinople observatory in Galata, "comparable in its technical equipment and its specialist personnel with that of his celebrated contemporary, the Danish astronomer Tycho Brahe." But while Brahe's observatory "opened the way to a vast new development of astronomical science," Taqi al-Din's was demolished by a squad of Janissaries, "by order of the sultan, on the recommendation of the Chief Mufti," sometime in 1580 CE on the grounds that it encouraged astrology and offended Allah to the point of punishing humanity by sending the plague. Though the causal logic may appear to be specious, Istanbul due it's centrality as a trade hub and large population was in fact a "plague hub" in that era.

Science and religious practice

Scientific methods have been historically applied to find solutions to the technical exigencies of Islamic religious rituals, which is a characteristic of Islam that sets it apart from other religions. These ritual considerations include a lunar calendar, definition of prayer times based on the position of the sun, and a direction of prayer set at a specific location. Scientific methods have also been applied to Islamic laws governing the distribution of inheritances and to Islamic decorative arts. Some of these problems were tackled by both medieval scientists of the Islamic world and scholars of Islamic law. Though these two groups generally used different methods, there is little evidence of serious controversy between them on these subjects, with the exception of the criticism leveled by religious scholars at the methods of astronomy due to its association with astrology.

Modern science in the Muslim world

At the beginning of the nineteenth century, modern science arrived in the Muslim world, bringing with it "the transfer of various philosophical currents entangled with science" including schools of thought such as Positivism and Darwinism. This had a profound effect on the minds of Muslim scientists and intellectuals and also had a noticeable impact on some Islamic theological doctrines.

While the majority of Muslim scientists tried to adapt their understanding of Islam to the findings of modern science, some rejected modern science as "corrupt foreign thought, considering it incompatible with Islamic teachings", others advocated for the wholesale replacement of religious worldviews with a scientific worldview, and some Muslim philosophers suggested separating the findings of modern science from its philosophical attachments. Among the majority of Muslim thinkers, a key justification for the use of modern science was the benefits that modern knowledge clearly brought to society. Others concluded that science could ultimately be reconciled with faith. A further apologetic trend saw the emergence of theories that scientific discoveries had been predicted in the Quran and Islamic tradition, thereby internalizing science within religion.

According to 2013 survey by the Pew Research Center asking Muslims in different Muslim majority countries in the Middle East and North Africa if there was a conflict between science and religion few agreed in Morocco (18%), Egypt (16%), Iraq (15%), Jordan (15%) and the Palestinian territories (14%). More agreed in Albania (57%), Turkey (40%), Lebanon (53%) and Tunisia (42%).

The poll also found a variance in how Muslim population in some countries are at odds with current scientific theories about biological evolution and the origin of man. Only four of the 22 countries surveyed that at least 50% of the Muslims surveyed rejected evolution (Iraq 67%, Tajikistan 55%, Indonesia 55%, Afghanistan 62%). Countries with relatively low rates of disbelief in evolution (i.e. agreeing to the statement "humans and other living things have always existed in present form") include Lebanon (21%), Albania (24%), Kazakhstan (16%).

As of 2018, three Muslim scientists have won a Nobel Prize for science (Abdus Salam from Pakistan in physics, Ahmed Zewail from Egypt and Aziz Sancar from Turkey in Chemistry). According to Mustafa Akyol, the relative lack of Muslim Nobel laureates in sciences per capita can be attributed to more insular interpretations of the religion than in the golden age of Islamic discovery and development, when Islamic society and intellectuals were more open to foreign ideas. Ahmed Zewail who won the 1999 Nobel Prize in Chemistry and is known as the father of femtochemistry said that "There is nothing fundamental in Islam against science."

However, according to an Islamic scholar from Indonesia, Harun Nasution, said that the stagnation and decline of Islamic civilization in the fields of science and technology was caused by none other than the type of theology that was widely accepted in Islamic society. He blamed Ash'arite theology, which is widely accepted by Muslim society, as the cause of scientific stagnation in the Muslim world. According to him, Ash'arite teachings prioritize occasionalism and fatalism which create a distance between science and Muslim society. On the contrary, he advocated the revival of Mu'tazila thought, known for its rationality, as a potential solution for scientific revival in Muslim society.

Conflict with religion

The conflicts between Islam and science can become quite complicated. It has been argued that "Muslims must be able to maintain the traditional Islamic intellectual space for the legitimate continuation of the Islamic view of the nature of reality to which Islamic ethics corresponds, without denying the legitimacy of modern science within their own confines". While the natural sciences have not been "fully institutionalized" in predominantly Islamic countries, engineering is considered an applied science that can function in conjunction with religion, and it is one of the most popular career choices of Middle Eastern students. Islamic academic Abu Ammaar Yasir Qadhi has noted that important technological innovations—once "considered to be bizarre, strange, haram (religiously forbidden), bidʻah (innovation), against the tradition" in the Muslim world, were later accepted as "standard".

An issue for accepting scientific knowledge rises from the supposed origin: For Muslims, absolute truth comes from God, not from the flawed human pursuit of knowledge. Islamic values hold that "knowledge of reality [is] based not on reason alone, but also on revelation and inspiration".

A passage in the Quran encourages congruency with the truth attained by modern science: "hence they should be both in agreement and concordant with the findings of modern science". This passage was used more often during the time where "modern science" was full of different discoveries. However, many scientific thinkers through the Islamic word still take this passage to heart when it comes to their work. There are also some strong believers that modern viewpoints, such as social Darwinism, challenged all medieval world views, including that of Islam. Some did not even want to be affiliated with modern science, and thought it was just an outside look into Islam. Many followers tend to see problems regarding the integration of Islam with science, and there are many that still stand by the viewpoints of Ahmad ibn Hanbal, that the pursuit of science is still the pursuit of knowledge:

One of the main reasons the Muslim world was held behind when Europe continued its ascent was that the printing press was banned. And there was a time when the Ottoman Sultan issued a decree that anybody caught with a printing press shall be executed for heresy, and anybody who owns a printed book shall basically be thrown into jail. And for 350 years when Europe is printing, when [René] Descartes is printing, when Galileo is printing, when [Isaac] Newton is printing, the only way you can get a copy of any book in the Arab world is to go and hand write it yourself.

The reluctance of the Muslim world to embrace science is manifest in the disproportionately small amount of scientific output, as measured by citations of articles published in internationally circulating science journals, annual expenditures on research and development, and numbers of research scientists and engineers.[47] Concerns have been raised that the contemporary Muslim world suffers from scientific illiteracy.[7] Skepticism of science among some Muslims is reflected in issues such as the resistance in Muslim northern Nigeria to polio inoculation, which some believe is "an imaginary thing created in the West or it is a ploy to get us to submit to this evil agenda." In Pakistan, a small number of post-graduate physics students have been known to blame earthquakes on "sinfulness, moral laxity, deviation from the Islamic true path", while "only a couple of muffled voices supported the scientific view that earthquakes are a natural phenomenon unaffected by human activity."

In the early twentieth century, Iranian Shia Ulama forbade the learning of foreign languages and the dissection of human bodies in the medical school in Iran. On the other hand, contrary to the current cliché concerning the opposition of the Imamate Shiite Ulama to modern astronomy in the nineteenth century, there is no evidence showing their literal or explicit objection to modern astronomy based on Islamic doctrines. They showed themselves the advocates of modern astronomy with the publication of Hibat al-Dīn Shahristānī's al-Islām wa al-Hayʾa (Islam and Astronomy) in 1910. After that, Shia ulama not only were not against the modern astronomy but also believed that the Quran and Islamic hadiths admit it.

During the twentieth century, the Islamic world introduction to modern science was facilitated by the expansion of educational systems. For example, in 1900 and 1925, Istanbul and Cairo opened universities. In these universities, new concerns have emerged among the students. One major issue was naturalism and social Darwinism, which challenged some beliefs. On the other hand, there were efforts to harmonize science with Islam. An example is the nineteenth-century study of Kudsî of Baku, who made connections between his discoveries in astronomy and what he knew from the Quran. These included "the creation of the universe and the beginning of like; in the second part, with doomsday and the end of the world; and the third was the resurrection after death".

Late Ottoman Empire and Turkey

Ahmet Hamdi Akseki, supported by the official institute for religious affairs in Turkey (Diyanet), published various articles about the creation of humanity. He emphazises that the purpose of the Quran is to offer parables and moral lessons, not offering scientific data or accounts of history. To demonstrate the ambiguity of the Islamic tradition in regards to the Earth's age he brings forth several narratives embedded in Islamic exegesis.

First, he recounts several narratives about creatures preceding the creation of Adam. Such species include hinn, binn, timm, rimm. A second one adds the belief that, before God has created Adam, thirty previous races were created, each with a gap of thousand years in between. During that time, the earth has been empty, until a new creation began to be formed. Lastly, he offers a dialogue between the Andalusian scholar ibn Arabi and a strange man:

During his visit to Mecca, he came across a person in strange cloths. When he asked the identity of the strange man, the man said: "I am from your ancient ancestors. I died forty thousand years ago!" Bewildered by this response, Ibn al-‘Arabı¯ asked, "What are you talking about? Books narrate that Adam was created about six thousand years ago." The man replied "What Adam are you talking about? Beware of the fact that there were a hundred thousand Adams before Adam, your ancestor."

The latter, so Akseki, underlines that the idea of Young Earth creationism is a challenge of the Judeo-Christian tradition. He admits that material of a young earth does exists among Muslim commentators, as in the case of ibn Arabi himself, but these are used as supplementary materials borrowed from Jewish sources (Isra'iliyyat) and are not part of the Islamic canon.

Süleyman Ateş, who was president of the Directorate of Religious Affairs in 1976-1978 and issued a tafsir (Interpretation of the Quran), employed similar arguments to that of Aksesi, while using references to Quranic verses to support his arguments. Pointing at 32:7, stating "He began the creation of man from clay.", he points out that humanity was not, in contrast to the Biblical interpretation, created an instant, but emerged as a process. To further support his argument to be in line with Islamic tradition, rather than a secular one, he looked at the Islamic heritage of previous scholars evoking the idea of an evolutionary process, such as the 9th century theologian Jahiz and the 18th century Turkish scholar İbrahim Hakkı Erzurumi, both utilized as references of pre-Darwinian accounts of evolution.

Hasan Karacadağ in his movie Semum, features the trope of conflict between science and religion. When the victim of the movie (Canan) is possessed by a demon, her husband brings her to a psychiatrist (Oğuz) and later to an excorcist (Hoca). A discussion starts between them, those practise is more beneficial to help Canan. While the psychiatrist symbolizes an anti-theistic attitude, Hoca represents a most faithful believer. The psychiatrist calls the Hoca a charlatan and dismisses his belief-system entire, while the Hoca affirms the validity of science, but asserts that science is limited to the knowable world, thus impotent in supernatural matters (i.e. the "unknown"). The Hoca, by his reconciling approach, is depicted as superior, when the demonic cause of Canan's illness is shown. Yet, the film makes clear that the psychiatrist does not fail on behalf of being a scientist, but by his anti-theistism. Exercised properly, science and religion would go hand in hand. When the director was asked if he himself believes in the existence of demons, he said that in such a "chaotic space" it is unlikely that humans are alone. His popular cultural depiction of demons might be seen as a representation of what lies beyond the limits of science, Islam being a tool to guide people to the unknown and unexplainable.

Islamist movements

Islamist author Muhammad Qutb (brother, and promoter, of Muslim Brotherhood leader Sayyid Qutb) in his influential book Islam, the misunderstood religion, states that "science is a powerful instrument" to increase human knowledge but has become a "corrupting influence on men's thoughts and feelings" for much of the world's population, steering them away from "the Right Path". As an example, he gives the scientific community's disapproval of claims of telepathy, when he claims that it is documented in hadith that Caliph Umar prevented commander Sariah from being ambushed by communicating with him telepathically. Muslim scientists and scholars have subsequently developed a spectrum of viewpoints on the place of scientific learning within the context of Islam.

Until the 1960s, Saudi Sunni ulama opposed any attempts at modernisation, considering them heretical (bidah). They opposed the spread of electricity, radios, and TVs. As recently as 2015, Sheikh Bandar al-Khaibari rejected the fact that the Earth orbits the Sun, instead claiming that the Earth is "stationary and does not move". In Afghanistan, Taliban have turned secular schools into Islamic madrasas, prioritizing religious studies over material science.

Science and the Quran

Many Muslims agree that doing science is an act of religious merit, even a collective duty of the Muslim community. According to M. Shamsher Ali, there are around 750 verses in the Quran dealing with natural phenomena. According to the Encyclopedia of the Quran, many verses of the Quran ask mankind to study nature, and this has been interpreted to mean an encouragement for scientific inquiry, and the investigation of the truth. Some include, "Travel throughout the earth and see how He brings life into being" (Q29:20), "Behold in the creation of the heavens and the earth, and the alternation of night and day, there are indeed signs for men of understanding ..." (Q3:190)

Mohammad Hashim Kamali has stated that "scientific observation, experimental knowledge and rationality" are the primary tools with which humanity can achieve the goals laid out for it in the Quran. Ziauddin Sardar argues that Muslims developed the foundations of modern science, by "highlighting the repeated calls of the Quran to observe and reflect upon natural phenomenon".

The physicist Abdus Salam believed there is no contradiction between Islam and the discoveries that science allows humanity to make about nature and the universe; and that the Quran and the Islamic spirit of study and rational reflection was the source of extraordinary civilizational development. Salam highlights, in particular, the work of Ibn al-Haytham and Al-Biruni as the pioneers of empiricism who introduced the experimental approach, breaking way from Aristotle's influence, and thus giving birth to modern science. Salam differentiated between metaphysics and physics, and advised against empirically probing certain matters on which "physics is silent and will remain so," such as the doctrine of "creation from nothing" which in Salam's view is outside the limits of science and thus "gives way" to religious considerations.

Islam has its own world view system including beliefs about "ultimate reality, epistemology, ontology, ethics, purpose, etc." according to Mehdi Golshani.

Toshihiko Izutsu writes that in Islam, nature is not seen as something separate but as an integral part of a holistic outlook on God, humanity, the world and the cosmos. These links imply a sacred aspect to Muslims' pursuit of scientific knowledge, as nature itself is viewed in the Quran as a compilation of signs pointing to the Divine. It was with this understanding that the pursuit of science, especially prior to the colonization of the Muslim world, was respected in Islamic civilizations.

The astrophysicist Nidhal Guessoum argues that the Quran has developed "the concept of knowledge" that encourages scientific discovery. He writes:

The Qur'an draws attention to the danger of conjecturing without evidence (And follow not that of which you have not the (certain) knowledge of... 17:36) and in several different verses asks Muslims to require proofs (Say: Bring your proof if you are truthful 2:111), both in matters of theological belief and in natural science.

Guessoum cites Ghaleb Hasan on the definition of "proof" according the Quran being "clear and strong... convincing evidence or argument." Also, such a proof cannot rely on an argument from authority, citing verse 5:104. Lastly, both assertions and rejections require a proof, according to verse 4:174Ismail al-Faruqi and Taha Jabir Alalwani are of the view that any reawakening of the Muslim civilization must start with the Quran; however, the biggest obstacle on this route is the "centuries old heritage of tafseer (exegesis) and other classical disciplines" which inhibit a "universal, epistemiological and systematic conception" of the Quran's message. The philosopher Muhammad Iqbal considered the Quran's methodology and epistemology to be empirical and rational.

Guessoum also suggests scientific knowledge may influence Quranic readings, stating that "for a long time Muslims believed, on the basis on their literal understanding of some Quranic verses, that the gender of an unborn baby is only known to God, and the place and time of death of each one of us is likewise al-Ghaib [unknown/unseen]. Such literal under-standings, when confronted with modern scientific (medical) knowledge, led many Muslims to realize that first-degree readings of the Quran can lead to contradictions and predicaments."

Islamists such as Sayyid Qutb argue that since "Islam appointed" Muslims "as representatives of God and made them responsible for learning all the sciences," science cannot but prosper in a society of true Islam. (However, since Muslim majority countries governments have failed to follow the sharia law in its completeness, true Islam has not prevailed and this explains the failure of science and many other things in the Muslim world, according to Qutb.)

Others claim traditional interpretations of Islam are not compatible with the development of science. Author Rodney Stark argues that Islam's lag behind the West in scientific advancement after (roughly) 1500 CE was due to opposition by traditional ulema to efforts to formulate systematic explanation of natural phenomenon with "natural laws." He claims that they believed such laws were blasphemous because they limit "God's freedom to act" as He wishes, a principle enshired in aya 14:4: "God sendeth whom He will astray, and guideth whom He will," which (they believed) applied to all of creation not just humanity.

Taner Edis wrote An Illusion of Harmony: Science and Religion in Islam. Edis worries that secularism in Turkey, one of the most westernized Muslim nations, is on its way out; he points out that the population of Turkey rejects evolution by a large majority. To Edis, many Muslims appreciate technology and respect the role that science plays in its creation. As a result, he says there is a great deal of Islamic pseudoscience attempting to reconcile this respect with other respected religious beliefs. Edis maintains that the motivation to read modern scientific truths into holy books is also stronger for Muslims than Christians. This is because, according to Edis, true criticism of the Quran is almost non-existent in the Muslim world. While Christianity is less prone to see its Holy Book as the direct word of God, fewer Muslims will compromise on this idea – causing them to believe that scientific truths simply must appear in the Quran. However, Edis argues that there are endless examples of scientific discoveries that could be read into the Bible or Quran if one would like to. Edis qualifies that Muslim thought certainly cannot be understood by looking at the Quran alone; cultural and political factors play large roles.

Miracle literature (Tafsir'ilmi)

Starting in the 1970s and 1980s, the idea of the presence of scientific evidence in the Quran became popularized as ijaz (miracle) literature. The genre of interpreting the Quran as revealing scientific truths before mankind's discovery is also known as Tafsir'ilmi. This approach gained much popularity through French author Maurice Bucaille, whose works have been distributed through Muslim bookstores and websites, and discussed on television programs by Islamic preachers. The movement contends that the Quran abounds with "scientific facts" that appeared centuries before their discovery by science and which "could not have been known" by people at the time. By asserting the presence of scientific truths stemming from the Quran, it also overlaps with Islamic creationism. This approach has been rejected by orthodox theologians who argue that the purpose of the Quran is religious guidance and not for proposing scientific theories.

According to author Ziauddin Sardar, the ijaz movement has created a "global craze in Muslim societies", and has developed into an industry that is "widespread and well-funded". Individuals connected with the movement include Abdul Majeed al-Zindani, who established the Commission on Scientific Signs in the Quran and Sunnah; Zakir Naik, the Indian televangelist; and Adnan Oktar, the Turkish creationist.

Enthusiasts of the movement argue that among the [scientific] miracles found in the Quran are "everything, from relativity, quantum mechanics, Big Bang theory, black holes and pulsars, genetics, embryology, modern geology, thermodynamics, even the laser and hydrogen fuel cells". Zafar Ishaq Ansari terms the modern trend of claiming the identification of "scientific truths" in the Quran as the "scientific exegesis" of the holy book.

An example is the verse: "So verily I swear by the stars that run and hide ..." (Q81:15–16), which proponents claim demonstrates the Quran's knowledge of the existence of black holes; or: "[I swear by] the Moon in her fullness that ye shall journey on from stage to stage" (Q84:18–19) refers, according to proponents, to human flight into outer space.

Embryology in the Quran

One claim that has received widespread attention and has even been the subject of a medical school textbook widely used in the Muslim world[84] is that several Quranic verses foretell the study of embryology and "provide a detailed description of the significant events in human development from the stages of gametes and conception until the full term pregnancy and delivery or even post partum."

In 1983, an authority on embryology, Keith L. Moore, had a special edition published of his widely used textbook on embryology (The Developing Human: Clinically Oriented Embryology), co-authored by a leader of the scientific miracles movement, Abdul Majeed al-Zindani. This edition, The Developing Human: Clinically Oriented Embryology with Islamic Additions, interspersed pages of "embryology-related Quranic verse and hadith" by al-Zindani into Moore's original work.

At least one Muslim-born physician (Ali A. Rizvi) studying the textbook of Moore and al-Zindani found himself "confused" by "why Moore was so 'astonished by'" the Quranic references, which Rizvi found "vague", and insofar as they were specific, preceded by the observations of Aristotle and the Ayr-veda, and/or easily explained by "common sense".

Some of the main verses are

  • (Q39:6) God creates us "in the womb of your mothers, creation after creation, within three darknessess," or "three veils of darkness". The "three" allegedly referring to the abdominal wall, the wall of the uterus, and the chorioamniotic membrane.
  • Verse Q32:9 identifies the order of organ development of the embryo—ears, then eyes, then heart.[
  • Verses referring to "sperm drop" (an-nutfa), and to al-3alaqa (translated as "clinging clot" or "leech like structure") in (Q23:13-14); and to "sperm-drop mixture" (an-nuṭfatin amshaajin) in (Q76:2). The miraculousness of these verse is said to come from the resemblance of the human embryo to a leech, and to the claim that "sperm-drop mixture" refers to a mixture sperm and egg.
  • (Q53:45-46) "And that He creates the two mates—the male and female—from a sperm-drop when it is emitted," allegedly refers to the fact that the sperm contributes X and Y chromosomes that determine the gender of the baby.

However,

  • The "three darknesses" or three walls (Q39:6) could easily have been observed by cutting open of pregnant mammals, something done by human beings before the revelation of the Quran ("dissections of human cadavers by Greek scientists have been documented as early as the third century BCE").
  • Contrary to the claims made about Q32:9, ears do not develop before eyes, which do not develop before heart. The heart begins development "at about 20 days, and the ears and eyes begin to develop simultaneously in the fourth week". However, the verse itself does not mention or claim the order of how the embryo will form first in the womb. "Then He proportioned him and breathed into him from His [created] soul and made for you hearing and vision and hearts; little are you grateful."
  • The embryo may resemble a leech (ala "clinging clot" or "leech like structure" of al-3alaqa in Q23:13-14), but it resembles many things during the eight week course of its development—none for very long.
  • While it is generally agreed the Quran mentions sperm (an-nutfa in several verses), "sperm-drop mixture" (an-nuṭfatin amshaajin in Q76:2) of a mixture of sperm and egg is more problematic as nowhere does the Quran mention the Egg cell or ovum—a rather glaring omission in any description of embryo development, as it the ovum the source of more than half the genetic material of the embryo.
  • With mention of male sperm but not female egg in the Quran, it seems likely Q53:45-46—"And that He creates the two mates, the male and female, from a sperm-drop when it is emitted"—is talking about the erroneous idea that all genetic material for offspring comes from the male and the mother simply provides a womb for the developing baby (as opposed to the sperm contributing the X and Y chromosomes that determine the gender of the baby). This idea originated with the ancient Greeks and was popular before modern biology developed.

In 2002, Moore declined to be interviewed by The Wall Street Journal on the subject of his work on Islam, stating that "it's been ten or eleven years since I was involved in the Quran."

Some researchers have proposed an evolutionary reading of the verses related to the creation of man in the Quran and then considered these meanings as examples of scientific miracles.

Criticism

Critics argue, verses that proponents say explain modern scientific facts, about subjects such as biology, the origin and history of the Earth, and the evolution of human life, contain fallacies and are unscientific.

As of 2008, both Muslims and non-Muslims have disputed whether there actually are "scientific miracles" in the Quran. Muslim critics of the movement include Indian Islamic theologian Maulana Ashraf Ali Thanwi, Muslim historian Syed Nomanul Haq, Muzaffar Iqbal, president of Center for Islam and Science in Alberta, Canada, and Egyptian Muslim scholar Khaled Montaser.

Pakistani theoretical physicist Pervez Hoodbhoy criticizes these claims and says there is no explanation that why many modern scientific discoveries such as quantum mechanics, molecular genetics, etc. were discovered elsewhere.

Giving the example of the roundness of the earth and the invention of the television, a Christian site ("Evidence for God's Unchanging World") complains the "scientific facts" are too vague to be miraculous.

Critics argue that while it is generally agreed the Quran contains many verses proclaiming the wonders of nature,

  • it requires "considerable mental gymnastics and distortions to find scientific facts or theories in these verses" (Ziauddin Sardar);
  • that the Quran is the source of guidance in right faith (iman) and righteous action (alladhina amanu wa amilu l-salihat) but the idea that it contained "all knowledge, including scientific" knowledge has not been a mainstream view among Muslim scholarship (Zafar Ishaq Ansari); and that "Science is ever-changing ... the Copernican revolution overturning polemic models of the universe to Einstein's general relativity overshadowing Newtonian mechanisms". So while "Science is probabilistic in nature" the Quran deals in "absolute certainty". (Ali Talib);

Nidhal Guessoum says that the central issue in the Islam-science discourse is the hierarchical positioning or place of the Quran in the scientific enterprise.

Mustansir Mir argues for a proper approach to Quran with regard to science that allows multiple and multi-level interpretations. He writes:

From a linguistic standpoint, it is quite possible for a word, phrase or statement to have more than one layer of meaning, such that one layer would make sense to one audience in one age and another layer of meaning would, without negating the first, be meaningful to another audience in a subsequent age.

History of science and technology

The history of science and technology (HST) is a field of history that examines the development of the understanding of the natural world (science) and humans' ability to manipulate it (technology) at different points in time. This academic discipline also examines the cultural, economic, and political context and impacts of scientific practices; it likewise may study the consequences of new technologies on existing scientific fields.

Academic study of history of science

History of science is an academic discipline with an international community of specialists. Main professional organizations for this field include the History of Science Society, the British Society for the History of Science, and the European Society for the History of Science.

Much of the study of the history of science has been devoted to answering questions about what science is, how it functions, and whether it exhibits large-scale patterns and trends.

History of the academic study of history of science

Histories of science were originally written by practicing and retired scientists, starting primarily with William Whewell's History of the Inductive Sciences (1837), as a way to communicate the virtues of science to the public.

Auguste Comte proposed that there should be a specific discipline to deal with the history of science.

The development of the distinct academic discipline of the history of science and technology did not occur until the early 20th century. Historians have suggested that this was bound to the changing role of science during the same time period.

After World War I, extensive resources were put into teaching and researching the discipline, with the hopes that it would help the public better understand both Science and Technology as they came to play an exceedingly prominent role in the world.

In the decades since the end of World War II, history of science became an academic discipline, with graduate schools, research institutes, public and private patronage, peer-reviewed journals, and professional societies.

Formation of academic departments

In the United States, a more formal study of the history of science as an independent discipline was initiated by George Sarton's publications, Introduction to the History of Science (1927) and the journal Isis (founded in 1912). Sarton exemplified the early 20th-century view of the history of science as the history of great men and great ideas. He shared with many of his contemporaries a Whiggish belief in history as a record of the advances and delays in the march of progress.

The study of the history of science continued to be a small effort until the rise of Big Science after World War II. With the work of I. Bernard Cohen at Harvard University, the history of science began to become an established subdiscipline of history in the United States.

In the United States, the influential bureaucrat Vannevar Bush, and the president of Harvard, James Conant, both encouraged the study of the history of science as a way of improving general knowledge about how science worked, and why it was essential to maintain a large scientific workforce.

Academic study of the history of science as an independent discipline was launched by George Sarton at Harvard with his book Introduction to the History of Science (1927) and the Isis journal (founded in 1912). Sarton exemplified the early 20th century view of the history of science as the history of great men and great ideas. He shared with many of his contemporaries a Whiggish belief in history as a record of the advances and delays in the march of progress.

The History of Science was not a recognized subfield of American history in this period, and most of the work was carried out by interested scientists and physicians rather than professional historians. With the work of I. Bernard Cohen at Harvard, the history of Science became an established subdiscipline of history after 1945.

Encyclopedia

From Wikipedia, the free encyclopedia
A laptop shows a Wikipedia page on "Encyclopedia", beside stacked volumes and an open page of the Encyclopædia Britannica.

An encyclopedia is a reference work or compendium providing summaries of knowledge, either general or special, in a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name by thematic categories, or, in the case of online encyclopedias, they are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on factual information concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.

Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a vernacular language), size (few or many volumes), intent (presentation of a global or a limited range of knowledge), cultural perspective (authoritative, ideological, didactic, utilitarian), authorship (qualifications, style), readership (education level, background, interests, capabilities), and the technologies available for their production and distribution (hand-written manuscripts, small or large print runs, Internet). As a valued source of reliable information compiled by experts, printed versions found a prominent place in libraries, schools, and other educational institutions.

In the 21st century the appearance of digital and open-source versions such as Wikipedia (together with the wiki website format) has vastly expanded the accessibility, authorship, readership, and variety of encyclopedia entries.

Etymology

Medieval manuscript containing the Greek phrase "enkúklios paideía"
A 15th-century manuscript of Institutio Oratoria. The Greek root of the word encyclopedia is highlighted.

The word encyclopedia comes from the Koine Greek ἐγκύκλιος παιδείαtransliterated enkúklios paideía 'general education', from enkúklios (ἐγκύκλιος) 'circular, recurrent, required regularly, general' and paideía (παιδεία) 'education, rearing of a child'; together, the phrase literally translates as 'complete instruction, complete knowledge'. However, the two separate words were reduced to a single word due to a scribal error by copyists of a Latin manuscript edition of Quintillian in 1470. The copyists took this phrase to be a single Greek word, enkuklopaideía, with the same meaning, and this spurious Greek word became the Neo-Latin word encyclopaedia, which was in turn borrowed into English. Because of this compounded word, readers since the fifteenth century have often, and incorrectly, thought that the Roman authors Quintillian and Pliny described an ancient genre. Following Noah Webster's spelling reform, the spelling of the word varies between encyclopedia in American English, encyclopaedia in British English (although the spelling encyclopedia is increasingly gaining acceptance), and encyclopædia in certain specialized cases.[]

Characteristics

The modern encyclopedia evolved from the dictionary in the 18th century; this lineage can be seen in the alphabetical order of print encyclopedias. Historically, both encyclopedias and dictionaries have been compiled by well-educated authors, but they are significantly different in structure. A dictionary is a linguistic work that primarily focuses on an alphabetical listing of words and their definitions. Synonymous words and those related by the subject matter are to be found scattered around the dictionary, giving no obvious place for in-depth treatment. Thus, a dictionary typically provides limited information, analysis or background for the word defined. While it may offer a definition, it may leave the reader lacking in understanding the meaning, significance or limitations of a term, and how the term relates to a broader field of knowledge.

To address those needs, an encyclopedia article is typically not limited to simple definitions, and is not limited to defining an individual word, but provides a more extensive meaning for a subject or discipline. The Merriam-Webster definition of encyclopedia states that it is "a work that contains information on all branches of knowledge or treats comprehensively a particular branch of knowledge usually in articles arranged alphabetically often by subject". In addition to defining and listing synonymous terms for the topic, the article can treat the topic's more extensive meaning in more depth and convey the most relevant accumulated knowledge on that subject. An encyclopedia article also often includes many maps and illustrations, as well as bibliography and statistics.

In addition, sometimes books or reading lists are compiled from a compendium of articles (either wholly or partially taken) from a specific encyclopedia.

Four major elements

Four major elements define an encyclopedia: its subject matter, its scope, its method of organization, and its method of production:

  1. Encyclopedias can be general, containing articles on topics in every field (the English-language Encyclopædia Britannica and German Brockhaus are well-known examples). General encyclopedias may contain guides on how to do a variety of things, as well as embedded dictionaries and gazetteers. There are also encyclopedias that cover a wide variety of topics from a particular cultural, ethnic, or national perspective, such as the Great Soviet Encyclopedia or Encyclopaedia Judaica.
  2. Works of encyclopedic scope aim to convey the important accumulated knowledge for their subject domain, such as an encyclopedia of medicine, philosophy or law. Works vary in the breadth of material and the depth of discussion, depending on the target audience.
  3. Some systematic methods of organization are essential to making an encyclopedia usable for reference. There have historically been two main methods of organizing printed encyclopedias: the alphabetical method (consisting of several separate articles, organized in alphabetical order) and organization by hierarchical categories. The former method is today the more common, especially for general works. The fluidity of electronic media, however, allows new possibilities for multiple methods of organization of the same content. Further, electronic media offer new capabilities for search, indexing and cross reference. The epigraph from Horace on the title page of the 18th century Encyclopédie suggests the importance of the structure of an encyclopedia: "What grace may be added to commonplace matters by the power of order and connection."
  4. As modern multimedia and the information age have evolved, new methods have emerged for the collection, verification, summation, and presentation of information of all kinds. Projects such as Interpedia, Everything2, Microsoft Encarta, h2g2, and Wikipedia are examples of new forms of the encyclopedia as information retrieval becomes simpler. The method of production for an encyclopedia historically has been supported in both for-profit and non-profit contexts; such was the case of the Great Soviet Encyclopedia mentioned above which was entirely state-sponsored, while the Britannica was supported as a for-profit institution.

Encyclopedic dictionaries

Some works entitled "dictionaries" are similar to encyclopedias, especially those concerned with a particular field (such as the Dictionary of the Middle Ages, the Dictionary of American Naval Fighting Ships, and Black's Law Dictionary). The Macquarie Dictionary, Australia's national dictionary, became an encyclopedic dictionary after its first edition in recognition of the use of proper nouns in common communication, and the words derived from such proper nouns.

Differences between encyclopedias and dictionaries

There are some broad differences between encyclopedias and dictionaries. Most noticeably, encyclopedia articles are longer, fuller, and more thorough than entries in most general-purpose dictionaries. There are differences in content as well. Generally speaking, dictionaries provide linguistic information about words themselves, while encyclopedias focus more on the concepts for which those words stand. Thus, while dictionary entries are inextricably fixed to the word described, encyclopedia articles can be given a different entry name. As such, dictionary entries are not fully translatable into other languages, but encyclopedia articles can be.

In practice, however, the distinction is not concrete, as there is no clear-cut difference between factual, "encyclopedic" information and linguistic information typically found in dictionaries. Thus, encyclopedias may contain material that is also found in dictionaries, and vice versa. In particular, dictionary entries often contain factual information about what the word refers to.

Pre-modern encyclopedias

Two pages from medieval manuscript of Pliny's Natural History
Pliny the Elder's Natural History is one of the oldest extant encyclopedias.

The earliest encyclopedic work to have survived to modern times is the Natural History of Pliny the Elder, a Roman statesman living in the 1st century AD, a work indebted to Varro (1st century BCE).  He compiled a work of 37 chapters covering natural history, architecture, medicine, geography, geology, and all aspects of the world around him.[] This work became very popular in antiquity, was one of the first classical manuscripts to be printed in 1470, and has remained popular ever since as a source of information on the Roman world, and especially Roman art, Roman technology and Roman engineering.

The Spanish scholar Isidore of Seville was the first Christian writer to try to compile a summa of universal knowledge, the Etymologiae (c. 600–625), also known by classicists as the Origines (abbreviated Orig.). This encyclopedia—the first such Christian epitome—formed a huge compilation of 448 chapters in 20 books based on hundreds of classical sources, including the Naturalis Historia. Of the Etymologiae in its time it was said quaecunque fere sciri debentur, "practically everything that it is necessary to know". Among the areas covered were: grammar, rhetoric, mathematics, geometry, music, astronomy, medicine, law, the Catholic Church and heretical sects, pagan philosophers, languages, cities, animals and birds, the physical world, geography, public buildings, roads, metals, rocks, agriculture, ships, clothes, food, and tools.

Another Christian encyclopedia was the Institutiones divinarum et saecularium litterarum of Cassiodorus (543–560) dedicated to the Christian divinity and the seven liberal arts. The encyclopedia of Suda, a massive 10th-century Byzantine encyclopedia, had 30,000 entries (broadly alphabetically arranged), many drawing from ancient sources that have since been lost, and often derived from medieval Christian compilers.

The Yongle Encyclopedia is the largest paper encyclopedia of world history

From India, the Siribhoovalaya (Kannada: ಸಿರಿಭೂವಲಯ), variously dated to c. 800 AD, the 15th century, or an even more recent time, is a work of Kannada literature written by Kumudendu Muni, a Jain monk. It is unique because rather than employing alphabets, it is composed entirely in Kannada numerals. Many philosophies which existed in the Jain classics are eloquently and skillfully interpreted in the work.

The 2nd century BC reference work Shiben has been described as a Chinese encyclopedia of genealogies, while the Huanglan, completed in the 220s, was an early leishu encyclopedia. The Yiwen Leiju, completed in 624, was a landmark literature encyclopedia of the early Tang dynasty; other important leishu encyclopedias from the Tang include the Chuxue ji and Liutie. The Tongdian, Tongzhi and Wenxian Tongkao were three comprehensive institutional encyclopedias of the Tang, Song and Yuan dynasties, and were collectively referred to as the Three Tongs (Santong). The enormous encyclopedic works of the Four Great Books of Song, compiled by the 11th century during the early Song dynasty (960–1279), was a massive literary undertaking for the time. The last encyclopedia of the four, the Prime Tortoise of the Record Bureau, amounted to 9.4 million Chinese characters in 1,000 written volumes. The Yongle Encyclopedia (completed 1408) comprised 11,095 volumes, making it the largest paper encyclopedia in world history.

There were many great encyclopedists throughout Chinese history, including the scientist and statesman Shen Kuo (1031–1095) with his Dream Pool Essays of 1088; the statesman, inventor, and agronomist Wang Zhen (active 1290–1333) with his Nong Shu of 1313; and Song Yingxing (1587–1666) with his Tiangong Kaiwu. Song Yingxing was termed the "Diderot of China" by British historian Joseph Needham.[]

Printed encyclopedias

Britannica 15th edition printed encyclopedias, 2002

Before the advent of the printing press, encyclopedic works were all hand-copied and thus rarely available, beyond wealthy patrons or monastic men of learning: they were expensive, and usually written for those extending knowledge rather than those using it. The introduction of printing from Asia allowed a wider diffusion of encyclopedias and every scholar could have his or her copy. Nuremberg Chronicle from 1493 is one of the best-documented early printed books—an incunabulum—and one of the first to successfully integrate illustrations and text. Both Latin and German editions were printed by Anton Koberger in Nuremberg. The De expetendis et fugiendis rebus by Giorgio Valla was posthumously printed in 1501 by Aldo Manuzio in Venice. This work followed the traditional scheme of liberal arts. However, Valla added the translation of ancient Greek works on mathematics (firstly by Archimedes), newly discovered and translated. The Margarita Philosophica by Gregor Reisch, printed in 1503, was a complete encyclopedia explaining the seven liberal arts.

Financial, commercial, legal, and intellectual factors changed the size of encyclopedias. Middle classes had more time to read and encyclopedias helped them to learn more. Publishers wanted to increase their output so some countries like Germany started selling books missing alphabetical sections, to publish faster. Also, publishers could not afford all the resources by themselves, so multiple publishers would come together with their resources to create better encyclopedias. Later, rivalry grew, causing copyright to occur due to weak underdeveloped laws. John Harris is often credited with introducing the now-familiar alphabetic format in 1704 with his English Lexicon Technicum: Or, A Universal English Dictionary of Arts and Sciences: Explaining not only the Terms of Art, but the Arts Themselves – to give its full title. Organized alphabetically, its content does indeed contain an explanation not merely of the terms used in the arts and sciences, but of the arts and sciences themselves. Sir Isaac Newton contributed his only published work on chemistry to the second volume of 1710.

Encyclopédie

Indeed, the purpose of an encyclopedia is to collect knowledge disseminated around the globe; to set forth its general system to the men with whom we live, and transmit it to those who will come after us, so that the work of preceding centuries will not become useless to the centuries to come; and so that our offspring, becoming better instructed, will at the same time become more virtuous and happy, and that we should not die without having rendered a service to the human race in the future years to come.

— Diderot

The Encyclopédie, ou dictionnaire raisonné des sciences, des arts et des métiers (French for 'Encyclopedia, or a Systematic Dictionary of the Sciences, Arts and Crafts'), better known as the Encyclopédie (French: [ɑ̃siklɔpedi]), was a general encyclopedia published in France between 1751 and 1772, with later supplements, revised editions, an index, and translations. It had many contributors, known among contemporaries as the Encyclopédistes. It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert.

The Encyclopédie is most famous for representing the thought of the Enlightenment. According to Diderot in the article "Encyclopédie", the Encyclopédie's aim was "to change the way people think" and to allow people to inform themselves. Diderot hoped the Encyclopédie would disseminate a vast amount of knowledge to the present and future generations. Thus, it is an example of democratization of knowledge, though the high price of the first edition especially (980 livres) prevented it from being bought by much of the middle class.

The Encyclopédie was also the first encyclopedia to include contributions from many named contributors, and it was the first general encyclopedia to describe the mechanical arts in much detail. In the first edition, seventeen folio volumes of text were accompanied by eleven volumes of engravings. Later editions were published in smaller formats and with fewer engravings in order to reach a wider audience within Europe.

Encyclopædia Britannica

The Encyclopædia Britannica (Latin for 'British Encyclopaedia') is a general-knowledge English-language encyclopaedia. It has been published since 1768, and after several ownership changes is currently owned by Encyclopædia Britannica, Inc. The 2010 version of the 15th edition, which spans 32 volumes and 32,640 pages, was the last printed edition. Since 2016, it has been published exclusively as an online encyclopaedia at the website Britannica.com.

Printed for 245 years, the Britannica was the longest-running in-print encyclopaedia in the English language. It was first published between 1768 and 1771 in Edinburgh, Scotland, in weekly instalments that came together to form three volumes. At first, the encyclopaedia, from edition to edition, grew quickly in size. The second edition was extended to 10 volumes, and by its fourth edition (1801–1810), the Britannica had expanded to 20 volumes. Since the beginning of the twentieth century, its size (at least in terms of total word length) has remained roughly steady, at about 40 million words.

The Britannica's rising stature as an authoritative and scholarly work helped recruit eminent contributors, and the 9th (1875–1889) and 11th editions (1911) are landmark encyclopaedias for scholarship and literary style. Starting with the 11th edition and following its acquisition by an American firm, the Britannica shortened and simplified articles to broaden its appeal to the North American market. Though published in the United States since 1901, the Britannica has for the most part maintained British English spelling.

In 1932, the Britannica adopted a policy of "continuous revision," in which the encyclopaedia is continually revised and reprinted, with every article updated on a schedule. The publishers of Compton's Pictured Encyclopedia had already pioneered such a policy.

The 15th edition (1974–2010) has a three-part structure: a 12-volume Micropædia of short articles (generally fewer than 750 words), a 17-volume Macropædia of long articles (two to 310 pages), and a single Propædia volume to give a hierarchical outline of knowledge. The Micropædia was meant for quick fact-checking and as a guide to the Macropædia; readers are advised to study the Propædia outline to understand a subject's context and to find more detailed articles.

In the 21st century, the Britannica faced strong competition: in particular from the digital and multimedia encyclopaedia Microsoft Encarta, and later from the online peer-produced encyclopaedia Wikipedia. Despite (or perhaps because of) such competition, Britannica retained its reputation for authoritative, comprehensive, structured, and scholarly treatments of included subjects. While it continued to score well in assessments of its overall quality, as compared to its competitors, it could not (as an expert-authored compilation of a limited number of articles on only important subjects), match their breadth of coverage and continuous updating.

In March 2012, it announced it would no longer publish printed editions and would focus instead on the online version.

Brockhaus Enzyklopädie

The Brockhaus Enzyklopädie (German for Brockhaus Encyclopedia) is a German-language encyclopedia which until 2009 was published by the F. A. Brockhaus printing house.

The first edition originated in the Conversations-Lexikon published by Renatus Gotthelf Löbel and Franke in Leipzig 1796–1808. Renamed Der Große Brockhaus in 1928 and Brockhaus Enzyklopädie from 1966, the 21st thirty-volume edition contains about 300,000 entries on about 24,000 pages, with about 40,000 maps, graphics and tables. It is the largest German-language printed encyclopedia in the 21st century.

In 2008, F. A. Brockhaus began the changeover to an online encyclopedia and the discontinuation of the printed editions. The rights to the Brockhaus trademark were purchased by Arvato, a subsidiary of the Bertelsmann media group. After more than 200 years, the distribution of the Brockhaus encyclopedia ceased completely in 2014.

Encyclopedias in the United States

In the United States, the 1950s and 1960s saw the introduction of several large popular encyclopedias, often sold on installment plans. The best known of these were World Book and Funk and Wagnalls. As many as 90% were sold door to door. Jack Lynch says in his book You Could Look It Up that encyclopedia salespeople were so common that they became the butt of jokes. He describes their sales pitch saying, "They were selling not books but a lifestyle, a future, a promise of social mobility." A 1961 World Book ad said, "You are holding your family's future in your hands right now," while showing a feminine hand holding an order form. As of the 1990s, two of the most prominent encyclopedias published in the United States were Collier's Encyclopedia and Encyclopedia Americana.

Digital encyclopedias

Physical media

By the late 20th century, encyclopedias were being published on CD-ROMs for use with personal computers. This was the usual way computer users accessed encyclopedic knowledge from the 1980s and 1990s. Later, DVD discs replaced CD-ROMs, and by the mid-2000s, internet encyclopedias were dominant and replaced disc-based software encyclopedias.

CD-ROM encyclopedias were usually a macOS or Microsoft Windows (3.0, 3.1 or 95/98) application on a CD-ROM disc. The user would execute the encyclopedia's software program to see a menu that allowed them to start browsing the encyclopedia's articles, and most encyclopedias also supported a way to search the contents of the encyclopedia. The article text was usually hyperlinked and also included photographs, audio clips (for example in articles about historical speeches or musical instruments), and video clips. In the CD-ROM age, the video clips usually had a low resolution, often 160x120 or 320x240 pixels. Such encyclopedias which made use of photos, audio and video were also called multimedia encyclopedias.

Microsoft's Encarta, launched in 1993, was a landmark example as it had no printed equivalent. It featured around 25,000 articles, supplemented with 7,000 high-quality images, 9 hours of audio files, and 30 videos. After sixteen years, Microsoft discontinued the Encarta line of products in 2009 with the rise of the Internet. Other examples of CD-ROM encyclopedia are Grolier Multimedia Encyclopedia and Britannica.

Digital encyclopedias enable "Encyclopedia Services" (such as Wikimedia Enterprise) to facilitate programmatic access to the content.

Online

Wikipedia is an example of an online encyclopedia, the content of which is created by volunteer contributors.

An online encyclopedia, also called an Internet encyclopedia, is a digital encyclopedia accessible through the Internet. Some examples include pre-World Wide Web services that offered the Academic American Encyclopedia beginning in 1980, Encyclopedia.com since 1998, Encarta from 2000 to 2009, Wikipedia since 2001, Encyclopædia Britannica since 2016, and Grokipedia since 2025.

Free encyclopedias

List of other free encyclopedias, from Enciclopedia Libre.

The concept of a free encyclopedia began with the Interpedia proposal on Usenet in 1993, which outlined an Internet-based online encyclopedia to which anyone could submit content that would be freely accessible. Early projects in this vein included Everything2 and Open Site. In 1999, Richard Stallman proposed the GNUPedia, an online encyclopedia which, similar to the GNU operating system, would be a "generic" resource. The concept was very similar to Interpedia, but more in line with Stallman's GNU philosophy.

It was not until Nupedia and later Wikipedia that a stable free encyclopedia project could be established on the Internet.

The English Wikipedia, which was started in 2001, became the world's largest encyclopedia in 2004 at the 300,000 article stage. By late 2005, Wikipedia had produced over two million articles in more than 80 languages with content licensed under the copyleft GNU Free Documentation License. As of August 2009, Wikipedia had over 3 million articles in English and well over 10 million combined articles in over 250 languages. Today, Wikipedia has 7,173,228 articles in English, over 60 million combined articles in over 300 languages, and over 250 million combined pages including project and discussion pages.

Since 2002, other free encyclopedias appeared, including Hudong (2005–) and Baidu Baike (2006–) in Chinese, and Google's Knol (2008–2012) in English. Some MediaWiki-based encyclopedias have appeared, usually under a license compatible with Wikipedia, including the Spanish encyclopedia Enciclopedia Libre (2002–2021) and the English encyclopedias Conservapedia (2006–), Scholarpedia (2006–), and Citizendium (2007–).
