Mark Nelkin

Mark Nelkin 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 Mark Nelkin rather than just read about it. In short: Mark Samuel Nelkin (born 12 May 1931) is an American theoretical physicist. Under the direction of Professor Hans Bethe, he received his Ph.D. in theoretical physics from Cornell University in 1955.

Key takeaways

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

Reference excerpt

Mark Samuel Nelkin (born 12 May 1931) is an American theoretical physicist. Under the direction of Professor Hans Bethe, he received his Ph.D. in theoretical physics from Cornell University in 1955. From 1955 to 1962 he worked in the nuclear industry for General Electric in Schenectady and General Atomic in San Diego. In 1962 he became a member of the Cornell faculty. He was awarded a Guggenheim Fellowship in 1968. He retired from Cornell University as professor emeritus in 1993. After retirement he moved to New York City and remained active in refereeing articles for Physical Review Letters, Physical Review E, The Physics of Fluids, and the Journal of Fluid Mechanics.

He spent leaves from Cornell at the University of Paris, The Collège de France in Paris, The National Bureau of Standards in Gaithersburg, Maryland, Harvard University, and the Courant Institute of Mathematical Sciences at New York University. At the Collège de France in 1976, he gave a series of twelve lectures on turbulence at the invitation of Pierre Gilles de Gennes. Nelkin became a Fellow of the American Physical Society in 1984, having been nominated by their Division of Fluid Dynamics, for contributions to the advancement of physics by strong theoretical contributions in four areas beginning with the physics of thermal neutrons and its applications to nuclear reactors, kinetic theory of fluctuations in fluids, turbulence, and 1/f noise. Nelkin was married to the American sociologist of science Dorothy Nelkin until her death in 2003.

Worked examples

Example 1 — a first encounter with Mark Nelkin

Start with the simplest possible case. Write down what Mark Nelkin 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 Mark Nelkin 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 Mark Nelkin 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 Mark Nelkin

In research: Mark Nelkin 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 Mark Nelkin 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: Mark Nelkin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 20th-century American physicists, 21st-century American physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Mark Nelkin 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.
