Biography Igor Troitski was born into a family of medical doctors. His mother – Bronislava Grigoryevna Lipnitskaya (1914–1996) – was a gynecologist. His father – Nikolai Alekseyevich Troitski (1896–1965) – was a professor in hospital therapy, who came into the field of medicine after graduating from theological seminary. Troitski spent The Great Patriotic War years (1941–1945) in evacuation in Northern Kazakhstan with his mother and grandmother. From 1945 to 1952, he lived in the village Saltykovka near Moscow, and then moved to Moscow with his family. In 1958, he graduated from high school № 453 with a Gold Medal. In 1958–1959, Troitski worked as a carpenter in Moscow ancillary production. In 1965, after graduating from the Moscow Institute of Physics and Technology, he received the qualification of an engineer-physicist and entered postgraduate studies. His scientific supervisor was the founder of the Soviet and Russian strategic missile and space defense system, Dr. Vladislav Repin. From 1965 to 1971, Troitski worked at the United Design Bureau (UDB) under the code name UDB "Vympel". In 1969, he received a Candidate of Sciences degree (a Soviet equivalent of Doctor of Philosophy [PhD]) and in 1978, he defended his subsequent dissertation and became a Doctor of Technical Sciences. In 1971, Troitski moved to Research and Production Association under the code name RPA "Astrofizika", where he was the Head of theoretical laboratory working on the development of optimal systems for laser locators. At the same time, from 1971 to 1988, he taught at the department of laser ranging systems of the Moscow Institute of Physics and Technology. During this period, Troitski partnered with others in the field to publish many textbooks, articles and books on the problems of statistical theory of holography, laser ranging and adaptive optics. In 1981, Troitski headed the research department focused on the development of systems using powerful laser installations, and was responsible for organizing and conducting experimental work on the effect of powerful laser radiation on various objects. From 1988 to 1992, Troitski worked at the S. I. Vavilov Institute of History of Natural Science and Technology of the USSR Academy of Sciences. In parallel, he lectured at the Bauman Moscow Higher Technical School. During this time, his research interests were focused on the creation of statistical theory of tomography. In 1994, Troitski took an active part in organizing the "Optics from Russia in New York" exhibition. In 1995, he coordinated and headed the optical research laboratory in New Jersey, where scientists and engineers from several Moscow institutes were invited under the SABIT program. The laboratory engaged in research on the creation of optical images based on the breakdown effect in various transparent materials and on the development of new holographic systems.

In 1995, Troitski, along with two Russian scientists and American partners, organized a joint company Laser-Tech Design for production of optical images by using lasers in various transparent materials. The company was based in Las Vegas, Nevada. In 1997, he formed a company, Igor Troitski, LLC. From 1998 to 2001, he was a co-owner of Crystal Magic, based in Orlando, Florida. The company produced laser images of Disney characters. In 2001, Troitski became a US citizen while retaining his Russian citizenship. In 2012, he concluded his research and production activities and focused on literary work. He wrote and published two autobiography books on his life in the USSR and the USA.

Family Igor Troitski was married two times. He shares a daughter Maria (born 1971) with his first wife – Tatiana Gorshkova. He shares a daughter Anna (born 1985) and grandson Yulian (born 2013) with his second wife – Olga Kharitonova. He currently lives in Las Vegas, Nevada, USA.

Worked examples

Example 1 — a first encounter with Igor Troitski

Start with the simplest possible case. Write down what Igor Troitski 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 Igor Troitski 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 Igor Troitski 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 Igor Troitski

In research: Igor Troitski 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 Igor Troitski 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: Igor Troitski is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1941 births, 20th-century American physicists, 20th-century Russian memoirists, so understanding it makes those chapters shorter.
In everyday life: Look for Igor Troitski 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.
