Gregg Thompson (astronomer)

Gregg Thompson (astronomer) 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 Gregg Thompson (astronomer) rather than just read about it. In short: Gregg D. Thompson of Brisbane, Australia is an amateur astronomer.

Key takeaways

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

Reference excerpt

Gregg D. Thompson of Brisbane, Australia is an amateur astronomer.

Astronomy Gregg Thompson was one of the founding members of the Southern Astronomical Society (SAS). Before 1981 he started making a set of charts of bright galaxies, designed to help deep sky observers in their search for extragalactic supernovae. In 1985 he received the Amateur Achievement Award of the Astronomical Society of the Pacific, together with Robert Owen Evans, who had made several supernova discoveries using Thompson's charts. Evans wrote that the number of galaxies he was able to observe grew substantially after the charts were produced. Gregg Thompson also helped verify some of Evans' discoveries.

Public outreach In 1990 Gregg Thompson co-authored with James T. Bryan, Jr. the astronomical atlas The Supernova Search Charts and Handbook, containing 248 comparison charts of 345 of the brightest galaxies, highly valued especially by supernova hunters and recommended by the Supernova Search Committee of the American Association of Variable Star Observers. In 1993 he published The Australian Guide to Stargazing, a manual for both naked-eye and telescope observing of the sky of the Southern Hemisphere with explanatory diagrams, photographs and detailed drawings, describing the basics of the night sky observation to novice amateur astronomers.

Worked examples

Example 1 — a first encounter with Gregg Thompson (astronomer)

Start with the simplest possible case. Write down what Gregg Thompson (astronomer) 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 Gregg Thompson (astronomer) 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 Gregg Thompson (astronomer) 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 Gregg Thompson (astronomer)

In research: Gregg Thompson (astronomer) 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 Gregg Thompson (astronomer) 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: Gregg Thompson (astronomer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Australian astronomers, 21st-century Australian astronomers, Amateur astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Gregg Thompson (astronomer) 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.
