Alan Paige Lightman (born November 28, 1948) is an American physicist, writer, and social entrepreneur. [1] [2] He has served on the faculties of Harvard University and Massachusetts Institute of Technology (MIT) and is currently a professor of the practice of the humanities at the Massachusetts Institute of Technology (MIT).
Lightman was one of the first persons at MIT to hold a joint faculty position in both the sciences and the humanities. [3] His thinking and writing explore the intersection of the sciences and humanities, especially the multilogues among science, philosophy, religion, and spirituality. [4] [5]
Lightman is a member of the United Nations’ Scientific Advisory Board, reporting directly to the Secretary General. The purpose of this Board is to advise UN leaders on breakthroughs in science and technology and mitigate potential risks, including ethical and social issues. [6]
Lightman is the author of the international bestseller Einstein's Dreams . [3] [7] and his novel The Diagnosis was a finalist for the National Book Award. [8] He is also the founder of Harpswell, a nonprofit organization whose mission is to advance a new generation of women leaders in Southeast Asia. [9]
Lightman hosts the public-television series Searching: Our Quest for Meaning in the Age of Science. [10]
He has received six honorary doctoral degrees.
Alan Lightman was born and grew up in Memphis, Tennessee. [11] His father Richard Lightman was a movie theater owner and played a major role in desegregating movie theaters in the South in 1962. [12] His mother Jeanne Garretson was a dance teacher and Braille typist.
Lightman graduated from White Station High School. [13] He graduated Phi Beta Kappa with an A.B. in physics from Princeton University in 1970 after completing a senior thesis, titled "Design and construction of a gas scintillation detector capable of time-of-flight measurements of fission isomer decays", under the supervision of Robert Naumann. [14] [15] He then received a Ph.D. in physics from the California Institute of Technology in 1974 after completing a doctoral dissertation, titled "I. Time-dependent accretion disks around compact objects. II. Theoretical frameworks for analyzing and testing gravitation theories", under the supervision of Kip S. Thorne. [16] [17]
Lightman was a postdoctoral fellow in astrophysics at Cornell University (1974–1976); an assistant professor at Harvard University (1976–1979); a senior research scientist at the Center for Astrophysics | Harvard & Smithsonian (1979–1989); and then a professor at the Massachusetts Institute of Technology (MIT) (1989– ). During this period he began publishing poetry in small magazines and eventually essays in Science 80, the Smithsonian, The New Yorker, and other magazines.
At MIT, in the mid-1990s Lightman chaired the committee that established the communication requirement for all undergraduates. In 2005, he was a cofounder of the Catalyst Collaborative at MIT, a partnership between MIT and Central Square Theater, in Cambridge, that sponsors plays involving science and the culture of science. [18] [19] In the same years, Lightman cofounded the graduate program in science writing at MIT.
In August 2023, Lightman was appointed a member of the United Nations’ Scientific Advisory Board, reporting directly to the Secretary General.
In his scientific work, Lightman has made contributions to the theory of astrophysical processes under extreme temperatures and densities. In particular, his research has focused on relativistic gravitation theory, the structure and behavior of accretion disks, stellar dynamics, radiative processes, and relativistic plasmas. Some of his significant achievements are his discovery, with Douglas Eardley, of a structural instability in orbiting disks of matter, called accretion disks, that form around massive condensed objects such as black holes, with wide application in astronomy; [20] his proof, with David L. Lee, that all gravitation theories obeying the Weak Equivalence Principle (the experimentally verified fact that all objects fall with the same acceleration in a gravitational field) must be metric theories of gravity, that is, must describe gravity as a geometrical warping of time and space; [21] his calculations, with Stuart L. Shapiro, of the distribution of stars around a massive black hole and the rate of destruction of those stars by the hole; [22] his discovery, independently of Roland Svensson of Sweden, of the negative heat behavior of optically thin, hot thermal plasmas dominated by electron-positron pairs, that is, the result that adding energy to thin hot gases causes their temperature to decrease rather than increase; [23] and his work on unusual radiation processes, such as unsaturated inverse Compton scattering, in thermal media, also with wide application in astrophysics. [24]
In 1990 he chaired the science panel of the National Academy of Sciences Astronomy and Astrophysics Survey Committee. He is a past chair of the High Energy Division of the American Astronomical Society.
Lightman's essays, articles, and stories have appeared in The Atlantic , Harper's Magazine , Nautilus , The New Yorker , The New York Times and other publications. [25] His books include:

In 2003, Lightman made his first trip to Southeast Asia, to Cambodia. There he met a Cambodian lawyer named Veasna Chea Leth who told him that when she had been going to university in Phnom Penh in the mid-1990s, she and a handful of female students lived underneath the university building, in the two-meter crawl space between the bottom of the building and the mud, because there was no housing for female university students. [32] [33] [34] Lightman and Chea together conceived the idea of a dormitory for female university students in Phnom Penh. That first facility was completed in 2006, the first dormitory for college women in the country.
During this work, Lightman founded Harpswell, [1] a nonprofit organization whose mission is to support emerging women leaders in Southeast Asia. Harpswell now operates two centers in Phnom Penh. In addition to providing housing, food, and medical care, the facility operates a program in leadership skills and critical thinking. The in-house program includes English instruction, computer literacy, debate, analytical writing, comparative genocide studies, strategies for civic engagement, leadership training, and discussion and analysis of national and international events. As of fall 2023, the Cambodian program has about 250 graduates and about 76 current students.[ citation needed ]
In 2017, Harpswell launched a new program in leadership for young professional women [35] from all ten countries of Southeast Asia: Laos, Myanmar, Thailand, Vietnam, Cambodia, Malaysia, the Philippines, Indonesia, Singapore, and Brunei, plus Nepal. The Harpswell-ASEAN Women's Leadership Summit consists of a ten-day summer program in Penang Malaysia, with lectures and workshops in critical thinking, civic engagement, Southeast Asian geography and society, technology and communication, and gender issues. The program has a total of 25 participants each year, who are flown to Penang from their respective countries.
A black hole is a region of spacetime wherein gravity is so strong that no matter or electromagnetic energy can escape it. Albert Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of no escape is called the event horizon. A black hole has a great effect on the fate and circumstances of an object crossing it, but it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly.

In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, into an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes.
Einstein's Dreams is a 1992 novel by Alan Lightman that was an international bestseller and has been translated into thirty languages. It was runner up for the 1994 L. L. Winship/PEN New England Award. Einstein's Dreams was also the March 1998 selection for National Public Radio's "Talk of the Nation" Book Club. The novel has been used in numerous colleges and universities, in many cases for university-wide adoptions in "common-book" programs. New York Times book critic Michiko Kakutani wrote about the book: "As in Calvino's work, the fantastical elements of the stories are grounded in precise, crystalline prose. As in Jorge Luis Borges's ficciones, carefully observed particulars open out, like doors in an advent calendar, to disclose a magical, metaphysical realm beyond."

An accretion disk is a structure formed by diffuse material in orbital motion around a massive central body. The central body is most frequently a star. Friction, uneven irradiance, magnetohydrodynamic effects, and other forces induce instabilities causing orbiting material in the disk to spiral inward toward the central body. Gravitational and frictional forces compress and raise the temperature of the material, causing the emission of electromagnetic radiation. The frequency range of that radiation depends on the central object's mass. Accretion disks of young stars and protostars radiate in the infrared; those around neutron stars and black holes in the X-ray part of the spectrum. The study of oscillation modes in accretion disks is referred to as diskoseismology.

Veasna Chea Leth is a lawyer from Cambodia, who was the first female law student at the Royal University of Law and Economics. During her studies in the 1990s she lived in an underground space under the university due to the lack of female dormitories. During her work as a lawyer she raised awareness of the issues that Cambodian women face in accessing university education, due to a lack of appropriate accommodation. This led to the author Alan Lightman establishing the Harpswell Foundation to support women, of which she is an Honorary Board Member.
