Pyotr Kropotkin (geologist)

Pyotr Kropotkin (geologist) is a earth science 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 Pyotr Kropotkin (geologist) rather than just read about it. In short: Pyotr Nikolayevich Kropotkin (Russian: Пётр Никола́евич Кропо́ткин; November 24, 1910, Moscow – 17 January 1996, Moscow) was a Soviet Russian geologist, tectonician, and geophysicist. Kropotkin came from an aristocratic family, he was the grand-nephew of the anarchist prince Peter Kropotkin.

Reference excerpt

Pyotr Nikolayevich Kropotkin (Russian: Пётр Никола́евич Кропо́ткин; November 24, 1910, Moscow – 17 January 1996, Moscow) was a Soviet Russian geologist, tectonician, and geophysicist. Kropotkin came from an aristocratic family, he was the grand-nephew of the anarchist prince Peter Kropotkin. His main publications were devoted to tectonics and its relationships with magmatism and to tectonic and geophysical problems. He developed a theory of the Earth's outgassing and abyssal inorganic origin of petroleum and coined the terms "cold outgassing". Kropotkin graduated from Moscow Geological Exploration Institute (MGRI) in 1932. He took part in prospecting for oil in the West Urals. Since 1936 he was with Geological Institute of Russian Academy of Sciences (RAS). He was elected a RAS Academician in 1992 and was awarded the Demidov Prize in 1994.

Worked examples

Example 1 — a first encounter with Pyotr Kropotkin (geologist)

Start with the simplest possible case. Write down what Pyotr Kropotkin (geologist) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, 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 Pyotr Kropotkin (geologist) 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 Pyotr Kropotkin (geologist) 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 Pyotr Kropotkin (geologist)

In research: Pyotr Kropotkin (geologist) appears in earth science 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 Pyotr Kropotkin (geologist) 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: Pyotr Kropotkin (geologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1910 births, 1996 deaths, Corresponding Members of the USSR Academy of Sciences, so understanding it makes those chapters shorter.
In everyday life: Look for Pyotr Kropotkin (geologist) 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.
