Pyotr Lukirsky

Pyotr Lukirsky 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 Pyotr Lukirsky rather than just read about it. In short: Pyotr Ivanovich Lukirsky (Russian: Пётр Иванович Лукирский; 13 December 1894 – 16 November 1954) was a Soviet physicist who specialized in experimental physics in radiation and optics. He was a student of Abram Ioffe and became a fellow of the Physico-Technical Institute.

Key takeaways

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

Reference excerpt

Pyotr Ivanovich Lukirsky (Russian: Пётр Иванович Лукирский; 13 December 1894 – 16 November 1954) was a Soviet physicist who specialized in experimental physics in radiation and optics. He was a student of Abram Ioffe and became a fellow of the Physico-Technical Institute. He contributed to industrial developments as well as to crystallography and basic physics.

Life and work Lukirsky was born in Orenburg where his father was a land surveyor. He was educated at Novgorod where the family moved and in 1912 he joined St. Petersburg University and graduated in 1915. He attended the seminars in physics of A. F. Ioffe. In 1918 he became a fellow at the physics institute founded by Ioffe and began to work on electron scattering from the surface of liquid mercury. He experimentally measured Planck constant with great accuracy. He also worked on X-ray (10–150 Å) scattering, conducted experiments on the polarization of X-rays, Compton scattering and photoelectric ion emission (the so-called photoeffect). In the 1930's he was a research consultant in the production of vacuum tubes at the Svetlana plant. He was also a noted lecturer and taught at the Leningrad University from 1919 to 1938. In 1938 he was arrested on charges of "fascist" activities by the NKVD (as part of Stalin's Great Purge which targeted a number of other physicists including Pyotr Kapitsa and Matvei Bronstein. Bronstein had been involved in the hiring of Lukirsky.) and sent to a labour camp in Usollag and was rehabilitated only in 1942 after numerous petitions from his colleague physicists. After his release he returned to the Physico-Technical Institute, heading it from 1945. He also worked at the Radium Institute from 1943 and was involved in problems in nuclear physics.

Worked examples

Example 1 — a first encounter with Pyotr Lukirsky

Start with the simplest possible case. Write down what Pyotr Lukirsky 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 Pyotr Lukirsky 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 Lukirsky 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 Lukirsky

In research: Pyotr Lukirsky 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 Pyotr Lukirsky 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 Lukirsky is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1894 births, 1954 deaths, Academic staff of Saint Petersburg State University, so understanding it makes those chapters shorter.
In everyday life: Look for Pyotr Lukirsky 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.
