Mykhailo Lysytsa

Mykhailo Lysytsa 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 Mykhailo Lysytsa rather than just read about it. In short: Mykhailo Pavlovych Lysytsa (Ukrainian: Михайло Павлович Лисиця; 15 January 1921, Vysoke – 10 January 2012, Kyiv) was a Soviet and Ukrainian physicist in the field of optics and spectroscopy, nonlinear optics and quantum electronics, solid-state physics and semiconductor physics. He was academician of the National Academy of Sciences of Ukraine (elected on 1 April 1982), Doctor of Physical and Mathematical Sciences (…

Key takeaways

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

Reference excerpt

Mykhailo Pavlovych Lysytsa (Ukrainian: Михайло Павлович Лисиця; 15 January 1921, Vysoke – 10 January 2012, Kyiv) was a Soviet and Ukrainian physicist in the field of optics and spectroscopy, nonlinear optics and quantum electronics, solid-state physics and semiconductor physics. He was academician of the National Academy of Sciences of Ukraine (elected on 1 April 1982), Doctor of Physical and Mathematical Sciences (1961), professor. He was awarded two State Prizes of Ukraine in Science and Technology. The asteroid 8064 Lisitsa was named after him.

Research At the beginning of his scientific career at Taras Shevchenko National University of Kyiv, he achieved first results in optics of thin metal layers, spectroscopy of organic liquids, and the creation of infrared radiation polarizers. Together with his students and postgraduates, he started research on semiconductor optics, which, since 1961, after his transition to the newly organized Academic Institute of Semiconductors, it became one of the main directions of his work. Lysytsa was one of the first among Ukrainian opticians to address the issues of laser physics and nonlinear optics in the early 1960s. Later, he became one the first among Ukrainian scientists to focus on fiber optics and co-authored with his students monograph on "Fiber Optics," which was soon translated into English.

Worked examples

Example 1 — a first encounter with Mykhailo Lysytsa

Start with the simplest possible case. Write down what Mykhailo Lysytsa 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 Mykhailo Lysytsa 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 Mykhailo Lysytsa 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 Mykhailo Lysytsa

In research: Mykhailo Lysytsa 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 Mykhailo Lysytsa 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: Mykhailo Lysytsa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1921 births, 2012 deaths, 20th-century Ukrainian inventors, so understanding it makes those chapters shorter.
In everyday life: Look for Mykhailo Lysytsa 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.
