Levon Chailakhyan

Levon Chailakhyan 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 Levon Chailakhyan rather than just read about it. In short: Levon Mikhailovich Chailakhyan (Armenian: Լևոն Միքայելի Չայլախյան, Russian: Левон Михайлович Чайлахян; 21 June 1928 – 23 February 2009) was a Russian physiologist, biophysicist, and embryologist, also a member of the Russian Academy of Sciences. He was a director of the Institute of Theoretical and Experimental Biophysics of Russian Academy of Sciences, located in Pushchino, Moscow Oblast.

Key takeaways

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

Reference excerpt

Levon Mikhailovich Chailakhyan (Armenian: Լևոն Միքայելի Չայլախյան, Russian: Левон Михайлович Чайлахян; 21 June 1928 – 23 February 2009) was a Russian physiologist, biophysicist, and embryologist, also a member of the Russian Academy of Sciences. He was a director of the Institute of Theoretical and Experimental Biophysics of Russian Academy of Sciences, located in Pushchino, Moscow Oblast. Chailakhyan published more than 450 works in Russian, and other countries around the world, he was also awarded the medal of the All-Russia Physiological Society. Chailakhyan along with B.N. Veprintsev, T.A. Sviridova, V.A. Nikitin had cloned the first mammal, known as Masha the mouse, which was ten years before Dolly the Sheep.

Biography Levon Chailakhyan was born in Yerevan to Mikhail Chailakhyan and Tamara Karlovna Amatuni-Chailakhyan. He was ethnic Armenian. When he was 19, Levon began his education at the Biological Faculty of the Moscow State University, and graduated with specializing in Human and animal physiology.

Worked examples

Example 1 — a first encounter with Levon Chailakhyan

Start with the simplest possible case. Write down what Levon Chailakhyan 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 Levon Chailakhyan 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 Levon Chailakhyan 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 Levon Chailakhyan

In research: Levon Chailakhyan 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 Levon Chailakhyan 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: Levon Chailakhyan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2009 deaths, 20th-century Russian scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Levon Chailakhyan 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.
