Karl Rebane

Karl Rebane 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 Karl Rebane rather than just read about it. In short: Karl Rebane (11 April 1926 – 4 November 2007) was an Estonian physicist. Biography He studied at the Tallinn Technical University from 1947 to 1949, and graduated from the Leningrad University in 1952.

Key takeaways

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

Reference excerpt

Karl Rebane (11 April 1926 – 4 November 2007) was an Estonian physicist.

Biography He studied at the Tallinn Technical University from 1947 to 1949, and graduated from the Leningrad University in 1952. He graduated from Leningrad University in 1955 with a doctorate in solid state theory. He also obtained a Doctor of Sciences in Theoretical Physics in 1964 from the Belarusian AS. He became a faculty member at Tartu University in 1955. He was Professor and Chair of the Experimental Physics Department between 1958 and 1960, and was Professor and Chair of the Joint Department of Laser Optics at the Institute of Physics between 1974 and 1993. He was president of the Estonian Academy of Sciences from 1973 to 1990.

Early life Karl Rebane was born in Pärnu, Estonia. His father, Karl Rebane Sr., was a bookkeeper. He was the second oldest out of five children. His brothers were Jaan Rebane, Toomas Rebane (:et) and Jüri Rebane. The war reached Estonia in 1941 and his family evacuated to a small village in the oblast of Chelyabinsk where he worked at the local kolkhoz and attended a school for displaced Estonian children in Verkhneuralsk. In the spring of 1944, he was called into military service and joined Eesti Laskurkorpus, an Estonian division of the Red Army, where he was a crew member of a 45 mm antitank gun. He was wounded in battle on November 23, 1944, on the Sõrve peninsula, Estonia.

Family He was married to Ljubov Rebane, and had two children, Inna and Aleksander Rebane. He also had three brothers, Jaan, Toomas, and Jüri Rebane.

Worked examples

Example 1 — a first encounter with Karl Rebane

Start with the simplest possible case. Write down what Karl Rebane 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 Karl Rebane 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 Karl Rebane 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 Karl Rebane

In research: Karl Rebane 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 Karl Rebane 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: Karl Rebane is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2007 deaths, 20th-century Estonian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Karl Rebane 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.
