Philip J. Hanlon

Philip J. Hanlon 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 Philip J. Hanlon rather than just read about it. In short: Philip James Hanlon (born April 10, 1955) is an American mathematician. He served as the 18th president of Dartmouth College from June 2013 to June 2023 and as the 13th provost and executive vice president for academic affairs of the University of Michigan from 2010 to 2013.

Key takeaways

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

Reference excerpt

Philip James Hanlon (born April 10, 1955) is an American mathematician. He served as the 18th president of Dartmouth College from June 2013 to June 2023 and as the 13th provost and executive vice president for academic affairs of the University of Michigan from 2010 to 2013.

Early life and education Hanlon was born and raised in Gouverneur, New York. He attended Dartmouth College, graduating Phi Beta Kappa with a Bachelor of Arts in 1977. While an undergraduate, he was a member of Alpha Delta, the fraternity that was a partial inspiration for the 1978 film Animal House. He earned a doctorate at the California Institute of Technology in 1981. His doctoral dissertation Applications of the Quaternions to the Study of Imaginary Quadratic Ring Class Groups was supervised by Olga Taussky-Todd.

Career After completing his postdoctoral work at the Massachusetts Institute of Technology, Hanlon joined the faculty of the University of Michigan in 1986. He moved from associate professor to full professor in 1990. He was the Donald J. Lewis Professor of Mathematics. He was the associate dean for planning and finance for the University of Michigan College of Literature, Science, and the Arts from 2001 to 2004 and the vice provost from 2004 to 2010. In 2010, he was appointed as the provost of the University of Michigan. In June 2013 he became the 18th president of Dartmouth College. On January 25, 2022, Hanlon announced he would be stepping down as president in June 2023.

Worked examples

Example 1 — a first encounter with Philip J. Hanlon

Start with the simplest possible case. Write down what Philip J. Hanlon 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 Philip J. Hanlon 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 Philip J. Hanlon 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 Philip J. Hanlon

In research: Philip J. Hanlon 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 Philip J. Hanlon 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: Philip J. Hanlon is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1955 births, California Institute of Technology alumni, Combinatorialists, so understanding it makes those chapters shorter.
In everyday life: Look for Philip J. Hanlon 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.
