Key takeaways

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

Reference excerpt

Jack Herschel Freed (born April 19, 1938) is an American chemist known for his pioneering work in electron paramagnetic resonance (aka electron spin resonance) spectroscopy. He is the Frank and Robert Laughlin Professor of Physical Chemistry, emeritus, at Cornell University.

Biography Jack Freed was born in New York City. He received his bachelor's degree in chemical engineering in 1958 from Yale University and his Ph.D. in chemistry in 1962 from Columbia University. Freed is currently the Frank and Robert Laughlin Professor of Physical Chemistry, emeritus, in the department of chemistry and chemical biology at Cornell University. In 2001, Freed founded the National Biomedical Center for Advanced Electron Spin Resonance Technology (ACERT) funded by National Institutes of Health and has been its director since then. In 2004, he was an editor for Journal of Physical Chemistry. Before that he was a fellow in numerous places such as Alfred P. Sloan Foundation, American Academy of Arts and Sciences, American Physical Society, John Simon Guggenheim Memorial Foundation, Hebrew University Institute for Advanced Studies, and Weizmann Institute of Science. In 2023, he received two grants totalling $7.8 million over five years from the National Institutes of Health to use electron-spin resonance (ESR) for the benefit of public health. Located in Baker Lab on Cornell’s Ithaca campus, this national resource will provide cutting-edge ESR spectroscopy for biomedical researchers engaged in projects aimed at understanding and combating diseases and ailments. The resource is the only one in the U.S of its kind.

Worked examples

Example 1 — a first encounter with Jack H. Freed

Start with the simplest possible case. Write down what Jack H. Freed 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 Jack H. Freed 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 Jack H. Freed 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 Jack H. Freed

In research: Jack H. Freed 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 Jack H. Freed 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: Jack H. Freed is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, 21st-century American physicists, Columbia Graduate School of Arts and Sciences alumni, so understanding it makes those chapters shorter.
In everyday life: Look for Jack H. Freed 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.
