Reference excerpt

Sidney Robert Nagel is an American physicist and the Stein-Freiler Distinguished Service Professor at the University of Chicago, where he is affiliated with the Department of Physics, the James Franck Institute, and the Enrico Fermi Institute. His research focuses on complex everyday physics such as "the anomalous flow of granular material, the long messy tendrils left by honey spooned from one dish to another, the pesky rings deposited by spilled coffee on a table after the liquid evaporates or the common splash of a drop of liquid onto a countertop." His work includes high-speed photography of splashing liquids and drop formation. Nagel was born September 28, 1948, in New York, the son of Ernest Nagel and brother of mathematician Alexander Nagel. His academic career began as a research associate at Brown University in 1974, and from there he went in 1976 to the University of Chicago, becoming a full professor in 1984, and gaining his present position in 2001.

Education Nagel graduated with a B.A. from Columbia University in 1969. He then received a Ph.D. in physics from Princeton University in 1975 after completing a doctoral dissertation, titled "Infrared properties of metals and wavevector dependent local field effects", under the supervision of Stephen E. Schnatterly.

Worked examples

Example 1 — a first encounter with Sidney R. Nagel

Start with the simplest possible case. Write down what Sidney R. Nagel claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Sidney R. Nagel 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 Sidney R. Nagel 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 Sidney R. Nagel

In research: Sidney R. Nagel appears in astronomy 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 Sidney R. Nagel 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: Sidney R. Nagel is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, 21st-century American physicists, Brown University alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Sidney R. Nagel 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.
