Nikolai Borisovich Delone

Nikolai Borisovich Delone 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 Borisovich Delone rather than just read about it. In short: Nikolai Delaunay, Jr. (aka Delone, Nikolai Borisovich; 22 May 1926 – 11 September 2008) was a Soviet physicist born in Leningrad, USSR (now Saint Petersburg, Russia).

Key takeaways

Nikolai Borisovich Delone 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 Borisovich Delone to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Nikolai Borisovich Delone from memory before moving on to harder problems.

Reference excerpt

Nikolai Delaunay, Jr. (aka Delone, Nikolai Borisovich; 22 May 1926 – 11 September 2008) was a Soviet physicist born in Leningrad, USSR (now Saint Petersburg, Russia).

Life Delaunay was born in Leningrad on 22 May 1926. He was the son of Boris Delaunay, a mathematician known for creating the Delaunay triangulation. He graduated from the Moscow Engineering Physics Institute in 1951, and obtained his PhD at the Lebedev Physical Institute in the late 1950s. Delaunay is recognized for the first observations of multiphoton ionization, in 1965. Delaunay, along with Maxim Ammosov and Vladimir P. Krainov, developed the ADK formula, relating tunneling ionization in laser fields. He was also a lecturer at the Moscow Institute of Physics and Technology. After the dissolution of the Soviet Union, he travelled abroad and worked on international collaborations on multiphoton physics. His son was Vadim Delaunay, a poet and dissident, who participated in the 1968 Red Square demonstration of protest against military suppression of the Prague Spring.

Publications Delone published over 200 scientific papers, a four-book series on the physics of strong laser fields and on multiphoton physics, and a series of high-school level Russian textbooks.

Worked examples

Example 1 — a first encounter with Nikolai Borisovich Delone

Start with the simplest possible case. Write down what Nikolai Borisovich Delone 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 Borisovich Delone 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 Borisovich Delone 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 Borisovich Delone

In research: Nikolai Borisovich Delone 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 Borisovich Delone 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 Borisovich Delone is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1926 births, 2008 deaths, 20th-century Russian physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Nikolai Borisovich Delone 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.
