Lisa Randall

Lisa Randall is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lisa Randall rather than just read about it. In short: Lisa Joy Randall (born June 18, 1962) is an American theoretical physicist and Frank B. Baird, Jr.

Key takeaways

  • Lisa Randall belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Lisa Randall to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Lisa Randall from memory before moving on to harder problems.

Reference excerpt

Lisa Joy Randall (born June 18, 1962) is an American theoretical physicist and Frank B. Baird, Jr. Professor of Science at Harvard University. 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. She co-developed the Randall–Sundrum model, first published in 1999 with Raman Sundrum.

Early life and education Randall was born in Queens, New York City, New York. She graduated from Stuyvesant High School in 1980, where she was a classmate of fellow physicist and science popularizer Brian Greene. She won first place in the 1980 Westinghouse Science Talent Search at the age of 18 and was also named a National Merit Scholar. She attended Harvard University, where she took Math 55, earned a BA in physics in 1983 and a PhD in theoretical particle physics in 1987 under Howard Georgi.

Work 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. 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.)

Writing and science popularization 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. 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. 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." 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. She was commonly asked about the misconception that the LHC could make black holes that could destroy the planet. She answered that it was "not even conceivable unless space and gravity are very different from what we thought." 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.

Professional organizations Randall is a fellow of the American Physical Society (2003) and a member of the American Academy of Arts and Sciences (2004), the National Academy of Sciences (2008), and the American Philosophical Society (2010). Randall has helped organize numerous conferences and has been on the editorial board of several major theoretical physics journals.

Awards and honors In autumn 2004, she was the most cited theoretical physicist of the previous five years. 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 in theoretical physics. Other honors:

J.J. Sakurai Prize for Theoretical Particle Physics 2019 Andrew Gemant Award, 2012 Golden Plate Award of the American Academy of Achievement, 2008 Lilienfeld Prize, 2007 E. A. Wood Science Writing Award, 2007 Klopsteg Memorial Award from the American Association of Physics Teachers (AAPT), 2006 Premio Caterina Tomassoni e Felice Pietro Chisesi, from the Sapienza University of Rome, 2003 National Science Foundation Young Investigator Award, 1992

Personal life

Randall's sister, Dana Randall, is a professor of computer science at Georgia Tech. Randall is an avid climber. A rockface along the Mill Creek near Dumont in Colorado, is named Lisa Randall Wall after her by a local climbing society. In a climbing accident, after falling from the cliff despite proper safety measures, she injured her heel.

Religious beliefs When asked whether she believes in God, Randall 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."

Epstein controversy Randall maintained multiple years of contact with financier and later convicted sex criminal Jeffrey Epstein, beginning in 2004, and continued after his 2008 conviction. In emails between the two contained in the Epstein files released by the Department of Justice, Randall joked with Epstein about his house arrest, which he was placed under after his conviction for soliciting sex with a minor in 2008, as well as Randall's lack of "Jew credit." Randall also visited Epstein's private Caribbean island and flew on his private jet in 2014. When asked to respond to Nature's request for comments, she declined.

Worked examples

Example 1 — a first encounter with Lisa Randall

Start with the simplest possible case. Write down what Lisa Randall claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lisa Randall before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lisa Randall ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lisa Randall

In research
Lisa Randall appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Lisa Randall in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Lisa Randall is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, 20th-century American physicists, 20th-century American women physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Lisa Randall outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
