Laird A. Thompson 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 Laird A. Thompson rather than just read about it. In short: Laird A. Thompson (born 6 September 1947), is a professor emeritus of astronomy at the University of Illinois Urbana-Champaign.

Key takeaways

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

Reference excerpt

Laird A. Thompson (born 6 September 1947), is a professor emeritus of astronomy at the University of Illinois Urbana-Champaign. Thompson graduated with a B.A. in both physics and astronomy from the University of California, Los Angeles in 1969. He received his Ph.D. in astronomy from the University of Arizona in 1974. He is professionally associated with the International Astronomical Union, the American Astronomical Society, the Astronomical Society of the Pacific, the International Society for Optical Engineering, and has served as an adjunct member of the Center for Adaptive Optics.

Work in Astronomy From 1974 to 1987, Thompson worked in extragalactic astronomy and he concentrated on clusters of galaxy, galaxy morphology, and galaxy redshift surveys. In 1978, along with Stephen Gregory, he discovered voids. In the early 1980s, he began to work on projects aimed at improving the image quality at ground-based telescopes. His first instrument was a microprocessor controlled tip-tilt system called ISIS which was built at the Institute for Astronomy for use at the Mauna Kea Observatory in Hawaii. From 1990 to present, Thompson has worked in adaptive optics.

Worked examples

Example 1 — a first encounter with Laird A. Thompson

Start with the simplest possible case. Write down what Laird A. Thompson 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 Laird A. Thompson 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 Laird A. Thompson 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 Laird A. Thompson

In research: Laird A. Thompson 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 Laird A. Thompson 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: Laird A. Thompson is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1947 births, American astronomers, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Laird A. Thompson 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.
