James L. Elliot

James L. Elliot 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 James L. Elliot rather than just read about it. In short: James Ludlow Elliot (June 17, 1943 – March 3, 2011) was an American astronomer and scientist who, as part of a team, discovered the rings around the planet Uranus. Elliot was also part of a team that observed global warming on Triton, the largest moon of Neptune.

Key takeaways

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

Reference excerpt

James Ludlow Elliot (June 17, 1943 – March 3, 2011) was an American astronomer and scientist who, as part of a team, discovered the rings around the planet Uranus. Elliot was also part of a team that observed global warming on Triton, the largest moon of Neptune.

Career Elliot was born in 1943 in Columbus, Ohio and received his S.B. degree from the Massachusetts Institute of Technology (MIT) in 1965 and his Ph.D. degree from Harvard University in 1972. He held a postdoctoral position in Laboratory for Planetary Studies at Cornell University, and joined the faculty of Cornell's Astronomy Department in 1977. After he discovered Uranus's rings alongside Edward Dunham and Jessica Mink at Cornell, he returned to MIT in 1978 to serve as Professor of Physics, Professor of Earth, Atmospheric, and Planetary Sciences, and Director of the George R. Wallace, Jr. Astrophysical Observatory until his death on March 3, 2011. There is some debate on whether Elliot, et al. discovered the rings of Uranus, or whether William Herschel made an observation in 1797. However, scientific consensus seems to support Elliot as the discoverer.

Honors Main-belt asteroid 3193 Elliot, discovered by astronomer Edward Bowell at Anderson Mesa Station in 1983, was named in his honor. The official naming citation was published by the Minor Planet Center on 22 June 1986 (M.P.C. 10848). The crater Elliot on Pluto is also named in his honor.

List of discovered minor planets Elliot is credited by the Minor Planet Center with the discovery of seven minor planets, including the trans-Neptunian object (95625) 2002 GX32, which he co-discovered at CTIO in 2002.

Worked examples

Example 1 — a first encounter with James L. Elliot

Start with the simplest possible case. Write down what James L. Elliot 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 L. Elliot 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 L. Elliot 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 L. Elliot

In research: James L. Elliot 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 L. Elliot 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 L. Elliot is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1943 births, 2011 deaths, 20th-century American astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for James L. Elliot 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.
