Gregory P. Laughlin 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 Gregory P. Laughlin rather than just read about it. In short: Gregory P. Laughlin is an American astrophysicist who is a professor of astronomy and astrophysics at Yale University.

Key takeaways

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

Reference excerpt

Gregory P. Laughlin is an American astrophysicist who is a professor of astronomy and astrophysics at Yale University. As a researcher, he is interested in hydrodynamic simulations, the characterization of extrasolar planets and planet-forming environments as well as the far future of the Universe. He has also published a paper on high-frequency trading and was involved in market prediction in 2014.

Education He received his Ph.D. in Astronomy and Astrophysics from UC Santa Cruz in 1994. He held an NSF/JSPS Fellowship in Tokyo and also did postdoctoral research at the University of Michigan and the UC Berkeley.

Career From 1999-2001, he worked for NASA as a Planetary Scientist at the Ames Research Center in California. In 1997, Laughlin published a 57-page paper in Reviews of Modern Physics about the far future of the universe that made the front page of the New York Times. This paper became the inspiration of the book The Five Ages of the Universe, which he wrote along with Fred Adams. He joined the UC Santa Cruz faculty in 2001. In 2004, he was recipient of an NSF CAREER award, and was promoted to Full Professor in 2007. In 2009, Laughlin calculated a value Earth at $5 quadrillion dollars to show a message of how precious the is and to not destroy it. In 2014, he published a paper on high-frequency trading, showing that even if a trader won only 51% of trades, they would be guaranteed to make a profit if they made enough trades. Next year in 2015, he co-founded the aggregated prediction platform Metaculus with Anthony Aguirre.

Worked examples

Example 1 — a first encounter with Gregory P. Laughlin

Start with the simplest possible case. Write down what Gregory P. Laughlin 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 Gregory P. Laughlin 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 Gregory P. Laughlin 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 Gregory P. Laughlin

In research: Gregory P. Laughlin 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 Gregory P. Laughlin 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: Gregory P. Laughlin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century births, American astronomer stubs, American astrophysicists, so understanding it makes those chapters shorter.
In everyday life: Look for Gregory P. Laughlin 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.
