Lisa Randall HonFInstP (born June 18, 1962) is an American theoretical physicist working in particle physics and cosmology. She is the Frank B. Baird, Jr. Professor of Science on the physics faculty of Harvard University. [1] Her research includes the fundamental forces of nature and dimensions of space. She studies the Standard Model, supersymmetry, possible solutions to the hierarchy problem concerning the relative weakness of gravity, cosmology of dimensions, baryogenesis, cosmological inflation, and dark matter. [2] She contributed to the Randall–Sundrum model, first published in 1999 with Raman Sundrum. [3]

Early life and education

Randall was born in Queens, New York City, New York. An alumna of Hampshire College Summer Studies in Mathematics, she graduated from Stuyvesant High School in 1980, [4] where she was a classmate of fellow physicist and science popularizer Brian Greene. [4] [5] She won first place in the 1980 Westinghouse Science Talent Search at the age of 18 and was also named a National Merit Scholar. At Harvard University, Randall earned both a BA in physics (1983) and a PhD in theoretical particle physics (1987) under Howard Georgi. [1]

Academia

Randall researches particle physics and cosmology at Harvard, where she is a professor of theoretical physics. Her research concerns elementary particles and fundamental forces, and has involved the study of a wide variety of models, the most recent involving dimensions. She has also worked on supersymmetry, Standard Model observables, cosmological inflation, baryogenesis, grand unified theories, and general relativity.

After her graduate work at Harvard, Randall held professorships at MIT and Princeton University before returning to Harvard in 2001. [6] Professor Randall was the first tenured woman in the Princeton physics department and the first tenured female theoretical physicist at Harvard. (Melissa Franklin was the first tenured woman in the Harvard physics department.) [7] [8]

Writing

Randall's books Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions and Knocking on Heaven’s Door: How Physics and Scientific Thinking Illuminate the Universe and the Modern World have both been on New York Times 100 notable books lists. [1]

Between the hardback and paperback release of Knocking on Heaven's Door, the quest for the discovery of the Higgs boson was actually completed, a subject discussed in the book. Scientists at the Large Hadron Collider found a particle identified as the Higgs boson. [9] [10] She said about the discovery, that even if people don't understand everything about it, "what an exciting thing it is that people are excited that there is something fundamentally new that has been discovered." [11] Randall has an e-book entitled Higgs Discovery: The Power of Empty Space. Before the Large Hadron Collider was operating, she wrote an article explaining the discoveries that were expected from using it. [12] She was commonly asked about the misconception that the LHC could make black holes that could destroy the planet. [13] She answered that it was "not even conceivable unless space and gravity are very different from what we thought." [12]

Randall wrote the libretto of the opera Hypermusic Prologue: A Projective Opera in Seven Planes on the invitation of the composer, Hèctor Parra, who was inspired by her book Warped Passages. [14]

Professional organizations

Randall is a member of the American Academy of Arts and Sciences (2004) and the National Academy of Sciences (2008), [2] the American Philosophical Society, [15] and a fellow of the American Physical Society.

Randall has helped organize numerous conferences and has been on the editorial board of several major theoretical physics journals. [1] [6]

Awards and honors

In autumn 2004, she was the most cited theoretical physicist of the previous five years. Professor Randall was featured in Seed magazine's "2005 Year in Science Icons" and in Newsweek 's "Who's Next in 2006" as "one of the most promising theoretical physicists of her generation". In 2007, Randall was named one of Time magazine's 100 Most Influential People (Time 100) under the section for "Scientists & Thinkers". Randall was given this honor for her work regarding the evidence of a higher dimension. [16]

Other honors:

Personal life

In an interview she was asked whether she believes in God, she said:

"... I probably don't believe in God. I think it's a problem that people are considered immoral if they're not religious. That's just not true. This might earn me some enemies, but in some ways they may be even more moral. If you do something for a religious reason, you do it because you'll be rewarded in an afterlife or in this world. That's not quite as good as something you do for purely generous reasons." [27]

Randall's sister, Dana Randall, is a professor of computer science at Georgia Tech. [28]

Particle physics Branch of physics concerning the nature of particles

Particle physics or high energy physics is the study of fundamental particles and forces that constitute matter and radiation. The fundamental particles in the universe are classified in the Standard Model as fermions and bosons. There are three generations of fermions, but ordinary matter is made only from the first fermion generation. The first generation consists of up and down quarks which form protons and neutrons, and electrons and electron neutrinos. The three fundamental interactions known to be mediated by bosons are electromagnetism, the weak interaction, and the strong interaction.

In physics, Randall–Sundrum models are models that describe the world in terms of a warped-geometry higher-dimensional universe, or more concretely as a 5-dimensional anti-de Sitter space where the elementary particles are localized on a (3 + 1)-dimensional brane or branes.

Hierarchy problem Unsolved problem in physics

In theoretical physics, the hierarchy problem is the problem concerning the large discrepancy between aspects of the weak force and gravity. There is no scientific consensus on why, for example, the weak force is 1024 times stronger than gravity.

Tom Kibble British physicist

Sir Thomas Walter Bannerman Kibble, was a British theoretical physicist, senior research investigator at the Blackett Laboratory and Emeritus Professor of Theoretical Physics at Imperial College London. His research interests were in quantum field theory, especially the interface between high-energy particle physics and cosmology. He is best known as one of the first to describe the Higgs mechanism, and for his research on topological defects. From the 1950s he was concerned about the nuclear arms race and from 1970 took leading roles in promoting the social responsibility of the scientist.

<i>Warped Passages</i> Book by Lisa Randall

Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions is the debut non-fiction book by Lisa Randall, published in 2005, about particle physics in general and additional dimensions of space in particular. The book has made it to top 50 at amazon.com, making it the world's first successful book on theoretical physics by a female author. She herself characterizes the book as being about physics and the multi-dimensional universe. The book describes, at a non-technical level, theoretical models Professor Randall developed with the physicist Raman Sundrum, in which various aspects of particle physics are explained in a higher-dimensional braneworld scenario. These models have since generated thousands of citations.

The J. J. Sakurai Prize for Theoretical Particle Physics, is presented by the American Physical Society at its annual April Meeting, and honors outstanding achievement in particle physics theory. The prize consists of a monetary award, a certificate citing the contributions recognized by the award, and a travel allowance for the recipient to attend the presentation. The award is endowed by the family and friends of particle physicist J. J. Sakurai. The prize has been awarded annually since 1985.

Physics beyond the Standard Model Theories trying to extend known physics

Physics beyond the Standard Model (BSM) refers to the theoretical developments needed to explain the deficiencies of the Standard Model, such as the inability to explain the fundamental parameters of the standard model, the strong CP problem, neutrino oscillations, matter–antimatter asymmetry, and the nature of dark matter and dark energy. Another problem lies within the mathematical framework of the Standard Model itself: the Standard Model is inconsistent with that of general relativity, and one or both theories break down under certain conditions, such as spacetime singularities like the Big Bang and black hole event horizons.
