Kip Thorne

Kip Thorne 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 Kip Thorne rather than just read about it. In short: Kip Stephen Thorne (born June 1, 1940) is an American astrophysicist and author. He shared the 2017 Nobel Prize in Physics with Rainer Weiss and Barry C.

Key takeaways

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

Reference excerpt

Kip Stephen Thorne (born June 1, 1940) is an American astrophysicist and author. He shared the 2017 Nobel Prize in Physics with Rainer Weiss and Barry C. Barish "for decisive contributions to the LIGO detector and the observation of gravitational waves". With John A. Wheeler and Charles Misner, he coauthored the general relativity textbook Gravitation in 1973. He has also written popular science, notably Black Holes and Time Warps in 1994 which was awarded the Phi Beta Kappa Award in Science for that year. Thorne was the Richard P. Feynman Professor of Theoretical Physics at Caltech from 1991 until 2009. A longtime friend and colleague of Stephen Hawking and Carl Sagan, he advised Sagan on the physics of wormholes for his novel Contact. He was a scientific consultant for Christopher Nolan's films Interstellar and Tenet. He received the 2018 Lewis Thomas Prize for science writing.

Life and career

Thorne was born on June 1, 1940, in Logan, Utah. His father, D. Wynne Thorne (1908–1979), was a professor of soil chemistry at Utah State University, and his mother, Alison (née Comish; 1914–2004), was an economist and the first woman to receive a PhD in economics from Iowa State College. Raised in an academic environment, two of his four siblings also became professors. Thorne's parents were members of the Church of Jesus Christ of Latter-day Saints (LDS Church) and raised Thorne in the LDS faith, though he now identifies as an atheist. Shortly before his mother's death, she urged Kip and his siblings to leave the LDS Church because of its discrimination against women, which they all did. Regarding his views on science and religion, Thorne has stated: "There are large numbers of my finest colleagues who are quite devout and believe in God .... There is no fundamental incompatibility between science and religion. I happen to not believe in God." Thorne excelled at academics early in life, winning recognition in the Westinghouse Science Talent Search as a senior at Logan High School. He received his BS in physics degree from Caltech in 1962, and his master and PhD in physics from Princeton University in 1964 and 1965 under the supervision of John Archibald Wheeler with a doctoral dissertation on Geometrodynamics of Cylindrical Systems. He returned to Caltech as an associate professor in 1967 and became a professor of theoretical physics in 1970, becoming one of the youngest full professors in the history of Caltech at age 30. He became the William R. Kenan Jr. Professor in 1981, and the Feynman Professor of Theoretical Physics in 1991. He was an adjunct professor at the University of Utah from 1971 to 1998 and Andrew D. White Professor at Large at Cornell University from 1986 to 1992. Since 2009, Thorne has been the Feynman Professor of Theoretical Physics, emeritus. Thorne and Linda Jean Peterson married in 1960. Their children are Kares Anne and Bret Carter, an architect. Thorne and Peterson divorced in 1977. Thorne was set up on a blind date with Lynda Obst, later a film producer, by physicist Carl Sagan. They dated in 1979–1980, and parted and remained friends, to the extent that they later collaborated on the movie Interstellar. Thorne and his second wife, Carolee Joyce Winstein, a professor of biokinesiology and physical therapy at USC, married in 1984. In 2015, he collaborated with Obst and Stephen Hawking on a movie script, for which they wrote several drafts. Throughout the years, Thorne has served as a mentor and thesis advisor to many students who became leaders in observational, experimental, or astrophysical aspects of general relativity. Approximately 50 physicists have received PhDs at Caltech under Thorne's personal mentorship. Thorne is known for his ability to convey the excitement and significance of discoveries in gravitation and astrophysics to both professional and lay audiences. His presentations on subjects such as black holes, gravitational radiation, relativity, time travel, and wormholes have been included in PBS shows in the U.S. and on the BBC in the United Kingdom. In 2017, Thorne gave the George Gamow Memorial Lecture at the University of Colorado Boulder, on “Probing the Warped Side of the Universe with Gravitational Waves: From the Big Bang to Black Holes.”

Research

Thorne's research has principally focused on relativistic astrophysics and gravitation physics, with emphasis on relativistic stars, black holes and especially gravitational waves. He is perhaps best known to the public for his controversial theory that wormholes can conceivably be used for time travel. However, Thorne's scientific contributions, which center on the general nature of space, time, and gravity, span the full range of topics in general relativity.

Worked examples

Example 1 — a first encounter with Kip Thorne

Start with the simplest possible case. Write down what Kip Thorne 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 Kip Thorne 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 Kip Thorne 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 Kip Thorne

In research
Kip Thorne 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 Kip Thorne 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
Kip Thorne is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, 21st-century American physicists, Albert Einstein Medal recipients, so understanding it makes those chapters shorter.
In everyday life
Look for Kip Thorne 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.
