Lyman Spitzer

Lyman Spitzer 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 Lyman Spitzer rather than just read about it. In short: Lyman Spitzer Jr. (June 26, 1914 – March 31, 1997) was an American theoretical physicist, astronomer and mountaineer.

Key takeaways

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

Reference excerpt

Lyman Spitzer Jr. (June 26, 1914 – March 31, 1997) was an American theoretical physicist, astronomer and mountaineer. As a scientist, he carried out research into star formation and plasma physics and in 1946 conceived the idea of telescopes operating in outer space. Spitzer invented the stellarator plasma device and is the namesake of NASA's Spitzer Space Telescope. As a mountaineer, he made the first ascent of Mount Thor, with Donald C. Morton.

Early life and education Spitzer was born to a Presbyterian family in Toledo, Ohio, the son of Lyman Spitzer Sr. and Blanche Carey (née Brumback). Through his paternal grandmother, he was related to inventor Eli Whitney. Spitzer graduated from Scott High School. He then attended Phillips Academy from 1929 to 1931 and went on to Yale College, where he graduated Phi Beta Kappa in 1935 and was a member of Skull and Bones. During a year of study at St John's College, Cambridge, he was influenced by Arthur Eddington and the young Subrahmanyan Chandrasekhar. Returning to the U.S., Spitzer received his Ph.D. in physics from Princeton University in 1938 after completing a doctoral dissertation, titled "The spectra of late supergiant stars", under the direction of Henry Norris Russell.

Mountaineering In 1965, Spitzer and Donald Morton became the first to climb Mount Thor 1,675 m (5,495 ft), located in Auyuittuq National Park, on Baffin Island, Nunavut, Canada. As a member of the American Alpine Club, Spitzer established the "Lyman Spitzer Cutting Edge Climbing Award" (Now called the "Cutting Edge Grant") which gives $12,000 to several mountain climbing expeditions annually.

Science

Spitzer's brief time as a faculty member at Yale was interrupted by his wartime work on the development of sonar. In 1947, at the age of 33, he succeeded Russell as director of Princeton University Observatory, an institution that, virtually jointly with his contemporary and friend Martin Schwarzschild, he continued to head until 1979. Spitzer's research centered on the interstellar medium, to which he brought a deep understanding of plasma physics. In the 1930s and 1940s, he was among the first to recognize star formation as an ongoing contemporary process. His monographs, "Diffuse Matter in Space" (1968) and "Physical Processes in the Interstellar Medium" (1978) consolidated decades of work, and themselves became the standard texts for some decades more. Spitzer was the founding director of Project Matterhorn, Princeton University's pioneering program in controlled thermonuclear research, renamed in 1961 as Princeton Plasma Physics Laboratory. He was an early proponent of space optical astronomy in general, and in particular of the project that became Hubble Space Telescope. In 1981, Spitzer became a founding member of the World Cultural Council.

Death

Spitzer died suddenly on March 31, 1997, after completing a regular day of work at Princeton University. He was buried at Princeton Cemetery and was survived by wife Doreen Canaday Spitzer (1914-2010), four children, and ten grandchildren. Among Spitzer's four children is neurobiologist Nicholas C. Spitzer, who is currently professor and vice chair in neurobiology at UC San Diego.

Worked examples

Example 1 — a first encounter with Lyman Spitzer

Start with the simplest possible case. Write down what Lyman Spitzer 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 Lyman Spitzer 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 Lyman Spitzer 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 Lyman Spitzer

In research
Lyman Spitzer 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 Lyman Spitzer 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
Lyman Spitzer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 1997 deaths, 20th-century American physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Lyman Spitzer 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.
