Lawrence Maxwell Krauss (born May 27, 1954) is an American theoretical physicist and cosmologist who is Foundation Professor of the School of Earth and Space Exploration at Arizona State University and director of its Origins Project.[2] He is known as an advocate of the public understanding of science, of public policy based on sound empirical data, of scientific skepticism and of science education and works to reduce the impact of what he opines as superstition and religious dogma in pop culture.[3] Krauss is also the author of several bestselling books, including The Physics of Star Trek and A Universe from Nothing, and chairs the Bulletin of the Atomic Scientists Board of Sponsors.[4]

Biography

Early life and education

Krauss was born in New York City, but spent his childhood in Toronto, Ontario, Canada.[5] Krauss received undergraduate degrees in mathematics and physics with first class honours at Carleton University (Ottawa) in 1977, and was awarded a Ph.D. in physics at the Massachusetts Institute of Technology in 1982.[6][7]

Personal life

On January 19, 1980, he married Katherine Kelley, a native of Nova Scotia. Their daughter, Lilli was born November 23, 1984. Krauss and Kelley separated in 2010 and were divorced in 2012. Krauss married Australian/American Nancy Dahl on January 7, 2014, and spends some of the Arizona summer in Australia at the Mount Stromlo Observatory.[8][9]

Career

After some time in the Harvard Society of Fellows, Krauss became an assistant professor at Yale University in 1985 and associate professor in 1988. He was named the Ambrose Swasey Professor of Physics, professor of astronomy, and was chairman of the physics department at Case Western Reserve University from 1993 to 2005. In 2006, Krauss led the initiative for the no-confidence vote against Case Western Reserve University's president Edward M. Hundert and provost Anderson by the College of Arts and Sciences faculty. On March 2, 2006, both no-confidence votes were carried: 131–44 against Hundert and 97–68 against Anderson.

In August 2008, Krauss joined the faculty at Arizona State University as a Foundation Professor in the School of Earth and Space Exploration at the Department of Physics in the College of Liberal Arts and Sciences. He also became the Director of the Origins Project, a university initiative.[10] In 2009, he helped inaugurate this initiative at the Origins Symposium, in which eighty scientists participated and three thousand people attended.[11]

Krauss appears in the media both at home and abroad to facilitate public outreach in science. He has also written editorials for The New York Times. As a result of his appearance in 2004 before the state school board of Ohio, his opposition to intelligent design has gained national prominence.[12]

Krauss attended and was a speaker at the Beyond Belief symposia in November 2006 and October 2008. He served on the science policy committee for Barack Obama's first (2008) presidential campaign and, also in 2008, was named co-president of the board of sponsors of the Bulletin of the Atomic Scientists. In 2010, he was elected to the board of directors of the Federation of American Scientists, and in June 2011, he joined the professoriate of the New College of the Humanities, a private college in London.[13] In 2013, he accepted a part-time professorship at the Research School of Astronomy and Astrophysics in the Physics Department of the Australian National University.[9]

Krauss is a critic of string theory, which he discusses in his 2005 book Hiding in the Mirror.[14] Another book, released in March 2011, was titled Quantum Man: Richard Feynman's Life in Science, while A Universe from Nothing —with an afterword by Richard Dawkins—was released in January 2012 and became a New York Times bestseller within a week. Originally, its foreword was to have been written by Christopher Hitchens, but Hitchens grew too ill to complete it.[15][16] The paperback version of the book appeared in January 2013 with a new question-and-answer section and a preface integrating the 2012 discovery of the Higgs boson at the LHC.

A July 2012 article in Newsweek, written by Krauss, indicates how the Higgs particle is related to our understanding of the Big Bang. He also wrote a longer piece in the New York Times explaining the science behind and significance of the particle.[17]

Scientific work

Krauss mostly works in theoretical physics and has published research on a great variety of topics within that field. His primary contribution is to cosmology as one of the first physicists to suggest that most of the mass and energy of the universe resides in empty space, an idea now widely known as "dark energy". Furthermore, Krauss has formulated a model in which the universe could have potentially come from "nothing," as outlined in his 2012 book A Universe from Nothing. He explains that certain arrangements of relativistic quantum fields might explain the existence of the universe as we know it while disclaiming that he "has no idea if the notion [of taking quantum mechanics for granted] can be usefully dispensed with".[18] As his model appears to agree with experimental observations of the universe (such as of its shape and energy density), it is referred to as a "plausible hypothesis".[19][20]

Initially, Krauss was skeptical of the Higgs mechanism. However, after the existence of the Higgs boson was confirmed by CERN, he has been researching the implications of the Higgs field on the nature of dark energy.[21]

Atheist activism

Krauss describes himself as an antitheist[22] and takes part in public debates on religion. Krauss featured in the 2013 documentary The Unbelievers, in which he and Richard Dawkins travel across the globe speaking publicly about the importance of science and reason as opposed to religion and superstition. The documentary also contains short clips of prominent figures such as Ayaan Hirsi Ali, Cameron Diaz, Sam Harris, and Stephen Hawking.[23]

In his book, A Universe from Nothing: Why There is Something Rather than Nothing (2012), Krauss discusses the premise that something cannot come from nothing, which has often been used as an argument for the existence of a Prime mover. He has since argued in a debate with John Ellis and Don Cupitt that the laws of physics allow for the universe to be created from nothing. "What would be the characteristics of a universe that was created from nothing, just with the laws of physics and without any supernatural shenanigans? The characteristics of the universe would be precisely those of the ones we live in." [24] In an interview with The Atlantic, however, he states that he has never claimed that "questions about origins are over." According to Krauss, "I don't ever claim to resolve that infinite regress of why-why-why-why-why; as far as I'm concerned it's turtles all the way down."[25]

Krauss has participated in many debates with theologians and apologists, including William Lane Craig and Hamza Tzortzis.[26] The debate with Tzortzis resulted in controversy when Krauss complained to the iERA organisers about the gender segregation of the audience; he only stayed when men and women were allowed to sit together.[27] Later, in discussions around secular liberal democracies and homosexuality, Krauss was asked "Why is incest wrong?" and answered that "Generally incest produces genetic defects" leading to "an ingrained incest taboo in almost all societies" though it could be theoretically permissible under rare circumstances where contraception is used.[28][29]

Honors

Krauss is one of the few living physicists described by Scientific American as a "public intellectual"[20] and he is the only physicist to have received awards from all three major American physics societies: the American Physical Society, the American Association of Physics Teachers, and the American Institute of Physics. In 2012, he was awarded the National Science Board's Public Service Medal for his contributions to public education in science and engineering in the United States.[30]

During December 2011, Krauss was named as a non-voting honorary board member for the Center for Inquiry.[31]

Bibliography

Krauss has authored or co-authored more than three hundred scientific studies and review articles on cosmology and theoretical physics.
