George B. Field

George B. Field 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 George B. Field rather than just read about it. In short: George B. Field (October 25, 1929 – July 31, 2024) was an American astrophysicist, Harvard University professor and founder director of the Harvard–Smithsonian Center for Astrophysics.

Key takeaways

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

Reference excerpt

George B. Field (October 25, 1929 – July 31, 2024) was an American astrophysicist, Harvard University professor and founder director of the Harvard–Smithsonian Center for Astrophysics. The Wouthuysen–Field coupling, a theoretical model used to study the phase transitions of the early universe, is named after him.

Early life, family and education Field was born in Providence, Rhode Island. His father Winthrop Brooks Field and mother Pauline Woodworth Field were Harvard and Radcliffe graduates, respectively. He was interested in astronomy at an early age, but at the urging of his father he studied chemical engineering at the Massachusetts Institute of Technology. Disliking engineering, he later switched to physics and astrophysics. After MIT, he attended graduate school at Princeton University, where his PhD advisor was Lyman Spitzer. At Princeton he had his first child, Christopher Field in 1957. Four years later, he had a daughter, Natasha Field, both with former wife Sylvia Field. From 1981 onward he was married to Susan Field.

Career He first worked on plasma oscillations and took a postdoctoral position at Harvard with Edward Mills Purcell. His interests evolved toward cosmology and the physics of the interstellar medium of galaxies. He was briefly on the faculty at Princeton before joining the faculty of the Department of Astronomy at the University of California, Berkeley where he remained until 1973. He left to become the founding director of the Center for Astrophysics (CfA) | Harvard & Smithsonian, an organizational structure that unified the Smithsonian Astrophysical Observatory (a government agency) and the Harvard College Observatory (a private institution) under a single management. Field served as Director until 1982, after which he remained the Robert Wheeler Wilson Professor of Applied Astronomy at Harvard until retirement. He was succeeded in the CfA Directorship by Irwin I. Shapiro. In the early 1980s, Field chaired an influential National Academy of Sciences decadal study that recommended priorities for US astronomical research. It was the third of what has become an extended series of Astronomy and Astrophysics Decadal Surveys, with format and goals now emulated by similar surveys in other disciplines. After his incumbency as CfA Director, his research focused on the theory of accretion disks in active galactic nuclei; cosmic birefringence; magnetohydrodynamics and magnetic fields in astronomy; and the structure of molecular clouds.

Doctoral students Among his doctoral student mentees were: Eric G. Blackman, Sean M. Carroll, Carl E. Heiles, Richard Conn Henry, Christopher McKee, Péter Mészáros and Paul R. Shapiro.

Worked examples

Example 1 — a first encounter with George B. Field

Start with the simplest possible case. Write down what George B. Field 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 George B. Field 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 George B. Field 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 George B. Field

In research
George B. Field 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 George B. Field 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
George B. Field is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1929 births, Fellows of the American Physical Society, Harvard University staff, so understanding it makes those chapters shorter.
In everyday life
Look for George B. Field 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.
