Reference excerpt

James Walter Warwick (1924–2013) was an American astronomer, a pioneer of low frequency radio astronomy.

Biography Warwick was born on May 22, 1924 in Toledo, Ohio. During the war, he served in the U.S. Army Air Corp as a Boeing B-29 Superfortress radar bombardier in the South Pacific. After the war he studied at Harvard University, and got his BA, MA, and PhD (1951) there. After graduation he worked on solar flares at Harvard College Observatory's Sacramento Peak Station in New Mexico, and the High Altitude Observatory in Boulder, Colorado. In 1955, he moved to University of Colorado Boulder, where he founded the Department of Astrogeophysics. He retired in 1989. Warwick was the principal investigator for Voyager program's Planetary Radio Astronomy instrument. He then left the University of Colorado Boulder, and founded Radiophysics, Inc. Warwick participated in IAU commissions on Radio Astronomy and on Solar Radiation. Warwick played clarinet in an army band during the war. At 39, he took cello lessons. He played cello and clarinet for the Boulder Philharmonic Orchestra and played at a local church. He was married three times.

Worked examples

Example 1 — a first encounter with James W. Warwick

Start with the simplest possible case. Write down what James W. Warwick 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 James W. Warwick 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 James W. Warwick 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 James W. Warwick

In research: James W. Warwick 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 James W. Warwick 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: James W. Warwick is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 births, 2013 deaths, American astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for James W. Warwick 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.
