Paul M. Feehan

Paul M. Feehan 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 M. Feehan rather than just read about it. In short: Paul Matthew Niall Feehan (born 1961) studied electrical engineering at University College Dublin (BE 1982) and the University of Missouri at Rolla (ME 1984), before switching to mathematics. His 1992 Ph.D. on "Geometry of the Moduli Space of Self-Dual Connections on the Four-Sphere" was done at Columbia University under Duong Hong Phong.

Key takeaways

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

Reference excerpt

Paul Matthew Niall Feehan (born 1961) studied electrical engineering at University College Dublin (BE 1982) and the University of Missouri at Rolla (ME 1984), before switching to mathematics. His 1992 Ph.D. on "Geometry of the Moduli Space of Self-Dual Connections on the Four-Sphere" was done at Columbia University under Duong Hong Phong. He worked for several years at UC Berkeley, Harvard, and Ohio State University, and in 2000 was appointed Erasmus Smith's Professor of Mathematics at Trinity College Dublin. However, a year later he accepted a position at Rutgers, where he now does research in non-linear elliptic and parabolic partial differential equations, differential geometry, mathematical physics, and the applications of partial-integral differential equations to derivative security pricing and risk management. He is also the Director of the Mathematical Finance Master's Degree Program at Rutgers. In 2019 he became a Fellow of the American Mathematical Society.

Worked examples

Example 1 — a first encounter with Paul M. Feehan

Start with the simplest possible case. Write down what Paul M. Feehan 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 M. Feehan 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 M. Feehan 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 M. Feehan

In research: Paul M. Feehan 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 M. Feehan 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 M. Feehan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1961 births, 20th-century Irish mathematicians, 21st-century Irish mathematicians, so understanding it makes those chapters shorter.
In everyday life: Look for Paul M. Feehan 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.
