Paul L. Schechter

Paul L. Schechter 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 L. Schechter rather than just read about it. In short: Paul L. Schechter (born May 30, 1948) is an American astronomer and observational cosmologist.

Key takeaways

Paul L. Schechter 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 L. Schechter to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Paul L. Schechter from memory before moving on to harder problems.

Reference excerpt

Paul L. Schechter (born May 30, 1948) is an American astronomer and observational cosmologist. He is the William A. M. Burden Professor of Astrophysics, Emeritus, at MIT. Schechter received his bachelor's degree from Cornell in 1968, and his Ph.D. degree from Caltech in 1975. He held postdoctoral positions at the Institute for Advanced Study and the University of Arizona, then went to Harvard as an assistant professor. He moved to his present position at MIT in 1988. Schechter was elected to the U.S. National Academy of Sciences in 2003. Schechter is known for his work establishing what is now known as the Schechter luminosity function for galaxies, and for work with William Press on what is now termed the Press–Schechter formalism. He also developed accurate methods for measuring velocity dispersions of galaxies, analyzed the Virgocentric infall, and performed precise analyses of gravitational lenses. Notable past students include Robert A. Simcoe.

Worked examples

Example 1 — a first encounter with Paul L. Schechter

Start with the simplest possible case. Write down what Paul L. Schechter 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 L. Schechter 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 L. Schechter 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 L. Schechter

In research: Paul L. Schechter 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 L. Schechter 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 L. Schechter is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, 20th-century American Jews, 21st-century American Jews, so understanding it makes those chapters shorter.
In everyday life: Look for Paul L. Schechter 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.
