Nikolai Kasterin

Nikolai Kasterin 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 Nikolai Kasterin rather than just read about it. In short: Nikolai Petrovich Kasterin (1869–1947) was a physicist and a student of Aleksandr Stoletov. His 1903 doctoral dissertation, portions of which were published in German in the Proceedings of the Royal Academy of Sciences in Amsterdam under the sponsorship of Heike Kamerlingh Onnes, is considered to be a pivotal contribution to multiple scattering theory (MST) by such experts as Paul Peter Ewald and Jan Korringa.

Key takeaways

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

Reference excerpt

Nikolai Petrovich Kasterin (1869–1947) was a physicist and a student of Aleksandr Stoletov. His 1903 doctoral dissertation, portions of which were published in German in the Proceedings of the Royal Academy of Sciences in Amsterdam under the sponsorship of Heike Kamerlingh Onnes, is considered to be a pivotal contribution to multiple scattering theory (MST) by such experts as Paul Peter Ewald and Jan Korringa. The MST formalism is widely used for electronic structure calculations as well as diffraction theory, and is the subject of many books. He lived in the Russian Empire and later the Soviet Union.

Biography Kasterin studied at the Physical-Mathematical Faculty of Moscow University under the supervision of Aleksandr Stoletov. He graduated in 1892 and continued to work for Stoletov as a laboratory assistant. In 1896-1899, he trained abroad. In 1899, Kasterin returned to Moscow University where he became an assistant professor and taught theoretical physics. In 1905, Kasterin defended his doctoral dissertation "On the propagation of waves in non-uniform medium". In 1906, Kasterin became a professor at the Department of Physics of Novorossiyskii University in Odessa. He also headed the Institute of Physics. From 1906 to 1922, he was the Chairman of the Department of Physics at Novorossiyskii University. In 1922, Kasterin moved to the Biophysics Institute in Moscow. Since 1930, he was a consultant for various scientific institutions including CAGI, Angarsrtoy and the National Institute of Building Materials. Kasterin authored more than forty scientific publications in theoretical physics. He was also known for his works opposing special relativity. In the summer of 1944, N. P. Kasterin’s work was criticized by the physics community of the USSR Academy of Sciences. On July 11, a letter from four academicians was sent to V. M. Molotov on behalf of A. F. Ioffe. In this letter, the work of N. P. Kasterin and A. K. Timiryazev was presented as a textbook example of pseudoscience.

Worked examples

Example 1 — a first encounter with Nikolai Kasterin

Start with the simplest possible case. Write down what Nikolai Kasterin 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 Nikolai Kasterin 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 Nikolai Kasterin 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 Nikolai Kasterin

In research
Nikolai Kasterin 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 Nikolai Kasterin 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
Nikolai Kasterin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1869 births, 1947 deaths, Moscow State University alumni, so understanding it makes those chapters shorter.
In everyday life
Look for Nikolai Kasterin 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.
