Ralph Elmer Wilson

Ralph Elmer Wilson is a astronomy 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 Ralph Elmer Wilson rather than just read about it. In short: Ralph Elmer Wilson (April 14, 1886 – March 25, 1960) was an American astronomer. Wilson was born in Cincinnati, Ohio, the son of Herbert Couper Wilson and Mary B.

Key takeaways

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

Reference excerpt

Ralph Elmer Wilson (April 14, 1886 – March 25, 1960) was an American astronomer. Wilson was born in Cincinnati, Ohio, the son of Herbert Couper Wilson and Mary B. Nichols. He earned his B.A. from Carleton College and entered the University of Virginia in 1906, where he earned his Ph.D. in 1910 based on his work at the Leander Mccormick Observatory working with Ormond Stone. He then worked at the Dudley Observatory, then at the Lick southern station in Santiago, Chile in 1913, and by 1939 at the Mount Wilson Observatory. In 1929, he became the associate editor of the Astronomical Journal. He was elected to the National Academy of Sciences in 1950. He published multiple papers on stellar absolute magnitudes, proper motions, and radial velocities of various stars, along with binary star systems and orbital derivations of spectroscopic binaries. Among his publications was the General Catalogue of Stellar Radial Velocities in 1953. The crater Wilson on the Moon is co-named for him, Alexander Wilson and Charles T. R. Wilson.

Worked examples

Example 1 — a first encounter with Ralph Elmer Wilson

Start with the simplest possible case. Write down what Ralph Elmer Wilson 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 Ralph Elmer Wilson 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 Ralph Elmer Wilson 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 Ralph Elmer Wilson

In research: Ralph Elmer Wilson 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 Ralph Elmer Wilson 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: Ralph Elmer Wilson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1886 births, 1960 deaths, 20th-century American people, so understanding it makes those chapters shorter.
In everyday life: Look for Ralph Elmer Wilson 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.
