Thor Rhodin

Thor Rhodin 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 Thor Rhodin rather than just read about it. In short: Thor Nathaniel Rhodin (December 9, 1920 – February 17, 2006) was an American professor of Applied and Engineering Physics at Cornell University and the University of Chicago's James Franck Institute, and is credited with pioneering work in the birth and evolution of surface science beginning with his research on surface sensitivity using auger electron spectroscopy. He played a major role, over several decades, in s…

Key takeaways

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

Reference excerpt

Thor Nathaniel Rhodin (December 9, 1920 – February 17, 2006) was an American professor of Applied and Engineering Physics at Cornell University and the University of Chicago's James Franck Institute, and is credited with pioneering work in the birth and evolution of surface science beginning with his research on surface sensitivity using auger electron spectroscopy. He played a major role, over several decades, in shaping the development of the field from fundamental work, using the field ion microscope, on the imaging and bonding of individual atoms at surfaces to the fundamentals of surface catalysis of hydrocarbon chemistry by the transition metals.

Education B.S. 1942 (Haverford College); Ph.D. 1946 (Princeton University)

Academic genealogy Thor Rhodin was a student of Hugh Scott Taylor. Taylor was a student of Frederick George Donnan and Henry Bassett [Ref.1]. Donnan was trained by Friedrich Wilhelm Ostwald. Ostwald's adviser was Schmidt, Carl, who was a student of Justus von Liebig. Bassett was trained by Adolf von Baeyer and Victor Villiger. Baeyer was a student of Robert Bunsen and Friedrich August Kekulé. Bunsen was a student of Friedrich Stromeyer. Kekulé was a student of Heinrich Will.

Worked examples

Example 1 — a first encounter with Thor Rhodin

Start with the simplest possible case. Write down what Thor Rhodin 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 Thor Rhodin 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 Thor Rhodin 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 Thor Rhodin

In research
Thor Rhodin 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 Thor Rhodin 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
Thor Rhodin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1920 births, 2006 deaths, American physicists, so understanding it makes those chapters shorter.
In everyday life
Look for Thor Rhodin 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.

Why does Thor Rhodin matter?

Because it connects several physics ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Thor Rhodin?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
