Patrick N. Keating

Patrick N. Keating 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 Patrick N. Keating rather than just read about it. In short: Dr. Patrick N.

Key takeaways

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

Reference excerpt

Dr. Patrick N. Keating was a theoretical physicist who contributed to several fields of solid-state physics, including semiconductors, semi-insulators and the basic properties of solid materials, and to other fields including optics, liquid crystals, acoustic holography, and signal processing. He was best known for the Keating Model of interatomic forces in tetrahedrally-coordinated solids (P. N. Keating, Effect of Invariance Requirements On The Elastic Strain Energy of Crystals, With Application to the Diamond Structure, Phys. Rev. 145, 637 (1966), which was determined to be one of the 50 highest-impact papers over a century of Physical Review publications).

Biography Dr. Keating was born in England and educated as a physicist there (University of Nottingham) and in the United States (University of Michigan, 1969). He served as Director and General Manager of both the Advanced Technology Center and the Microelectronics Center of Allied-Signal Corporation (now part of Honeywell Inc.), and lived in Maryland, Florida, and Delaware with his wife of 30 years, Julie Scott Keating. He had two married daughters, Clare and Fiona. Keating was an enthusiastic tennis player, golfer, sailor, and aviator, and held an FAA pilot's license. He died in Lakewood Ranch, Florida, on 21 January 2019. In addition to his contributions to the science of Physics, Dr. Keating's research interests included Climate Science, and a research paper in that field was published in the International Journal of Climatology.

Worked examples

Example 1 — a first encounter with Patrick N. Keating

Start with the simplest possible case. Write down what Patrick N. Keating 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 Patrick N. Keating 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 Patrick N. Keating 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 Patrick N. Keating

In research: Patrick N. Keating 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 Patrick N. Keating 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: Patrick N. Keating is common in secondary-school and first-year university syllabi. It links to neighbouring topics British physicist stubs, British physicists, British theoretical physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Patrick N. Keating 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.
