Paul Wiegert

Paul Wiegert 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 Paul Wiegert rather than just read about it. In short: Paul Arnold Wiegert (born 1967) is a Canadian astronomer, discoverer of minor planets and professor at the University of Western Ontario.

Key takeaways

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

Reference excerpt

Paul Arnold Wiegert (born 1967) is a Canadian astronomer, discoverer of minor planets and professor at the University of Western Ontario. Wiegert studies unusual orbits of both observed objects and theorised classes of objects, for example, one early paper considers not-known-to-exist planets orbiting the nearby Alpha Centauri star system, while later papers extend that case to more general planetary stability in general binary systems (as exoplanet studies are finding increasingly frequently). This work in particular should be of interest to science fiction authors inventing universes. Other areas of work include identifying the orbits of minor planets in the Solar System, which by virtue of their potential instability could realistically become major threats to civilization when one impacts on Earth again, as they have in the past. The Minor Planet Center credits him with the discovery of 80 numbered minor planets between 2003 and 2008. Wiegert was also involved in the discovery of 3753 Cruithne, Earth's first known Trojan asteroid. He was also the a member of the team that identified 524522 Zoozve, as a quasi-satellite of Venus, in 2004, two years after the actual discovery of the object. The outer main-belt asteroid 15068 Wiegert was named in his honor.

Worked examples

Example 1 — a first encounter with Paul Wiegert

Start with the simplest possible case. Write down what Paul Wiegert 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 Paul Wiegert 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 Paul Wiegert 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 Paul Wiegert

In research: Paul Wiegert 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 Paul Wiegert 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: Paul Wiegert is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1967 births, 21st-century Canadian astronomers, Academic staff of the University of Western Ontario, so understanding it makes those chapters shorter.
In everyday life: Look for Paul Wiegert 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.
