Richard J. O'Connell

Richard J. O'Connell is a physics 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 Richard J. O'Connell rather than just read about it. In short: Richard John O'Connell (August 27, 1941 – April 2, 2015) was an American geophysicist working on the internal dynamics of the Earth and how they evolved over time and are observed at the surface. He received his B.S., M.S., and Ph.D. degrees from California Institute of Technology, and spent most of his further academic career at Harvard University.

Key takeaways

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

Reference excerpt

Richard John O'Connell (August 27, 1941 – April 2, 2015) was an American geophysicist working on the internal dynamics of the Earth and how they evolved over time and are observed at the surface. He received his B.S., M.S., and Ph.D. degrees from California Institute of Technology, and spent most of his further academic career at Harvard University. O'Connell received the Inge Lehmann Medal from American Geophysical Union in 2000, the Arthur L. Day Medal from Geological Society of America in 2001, and the Augustus Love Medal from the European Geosciences Union in 2008. He was a fellow of the American Geophysical Union, the American Association for the Advancement of Science, and American Academy of Arts and Sciences.

Worked examples

Example 1 — a first encounter with Richard J. O'Connell

Start with the simplest possible case. Write down what Richard J. O'Connell claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, 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 Richard J. O'Connell 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 Richard J. O'Connell 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 Richard J. O'Connell

In research: Richard J. O'Connell appears in physics 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 Richard J. O'Connell 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: Richard J. O'Connell is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 2015 deaths, American geophysicists, so understanding it makes those chapters shorter.
In everyday life: Look for Richard J. O'Connell 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.
