Otto Ernst Heinrich Klemperer

Otto Ernst Heinrich Klemperer 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 Otto Ernst Heinrich Klemperer rather than just read about it. In short: Otto Ernst Heinrich Klemperer (1899 – 1987) was a physicist expert in electron optics. He was granted his doctorate by the Humboldt-Universität zu Berlin in 1923.

Key takeaways

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

Reference excerpt

Otto Ernst Heinrich Klemperer (1899 – 1987) was a physicist expert in electron optics. He was granted his doctorate by the Humboldt-Universität zu Berlin in 1923. His thesis advisor was Hans Geiger. He continued to work with Geiger in the 1930s. Klemperer was co-inventor in 1928 of the Geiger-Klemperer ball counter, "the first major advance in the design of proportional counters". During the 1930s, he worked at the Cavendish Laboratory at the University of Cambridge on discrepancies between Fermi's theory of β-decay and the observed radiation properties of rubidium and polonium. He was later an assistant professor and Reader in Physics at Imperial College, London, where he wrote the third edition of his book on electron optics with Mike Barnett. The conductor Otto Klemperer was his father's cousin. His uncle was the Romanist Victor Klemperer.

Worked examples

Example 1 — a first encounter with Otto Ernst Heinrich Klemperer

Start with the simplest possible case. Write down what Otto Ernst Heinrich Klemperer 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 Otto Ernst Heinrich Klemperer 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 Otto Ernst Heinrich Klemperer 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 Otto Ernst Heinrich Klemperer

In research: Otto Ernst Heinrich Klemperer 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 Otto Ernst Heinrich Klemperer 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: Otto Ernst Heinrich Klemperer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1899 births, 1987 deaths, 20th-century German physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Otto Ernst Heinrich Klemperer 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.
