Norair Sisakian

Norair Sisakian is a chemistry 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 Norair Sisakian rather than just read about it. In short: Norair Martirosovich Sisakian (Sissakian) (Armenian: Նորայր Մարտիրոսի Սիսակյան; Russian: Норайр Мартиросович Сисакян, 25 January 1907 – 12 March 1966) was a Soviet biologist of Armenian origin who worked as an engineer in the Soviet space program, working mainly on biomechanics effects. Sisakian is also one of the founders of space biology, an outstanding organizer of science, a member of the Pugwash movement.

Key takeaways

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

Reference excerpt

Norair Martirosovich Sisakian (Sissakian) (Armenian: Նորայր Մարտիրոսի Սիսակյան; Russian: Норайр Мартиросович Сисакян, 25 January 1907 – 12 March 1966) was a Soviet biologist of Armenian origin who worked as an engineer in the Soviet space program, working mainly on biomechanics effects. Sisakian is also one of the founders of space biology, an outstanding organizer of science, a member of the Pugwash movement. He was a Member of the Presidium of the Academy of Sciences of the Soviet Union, a member of the Armenian Academy of Sciences, the vice-president of the International Academy of Astronautics, the Chairman of the Committee on Bioastronautics of the International Astronautics Federation. In 1964 he was unanimously elected as a President of the 21st session of the UNESCO General Conference.

Biography Sisakian finished the Yerevan State University and then the Moscow Agricultural Academy in 1932. From 1935 he worked in the Moscow Institute of biochemics after A. N. Bach. Professor of the Moscow State University. During his life Sisakian created fourteen laboratories and the Puschin center of the Russian Academy of Sciences. He is well known for his concept on chloroplasts as poly-functional cell structures. He greatly contributed to the Soviet space program. A crater on the Far side of the Moon was named in his honor. In 2001 the "Academician Norair Martirosovich Sissakian" book was released by the Russian publishing house "Nauka". A school and a prospect in Yerevan are named after him. A museum of Sisakian was opened in his hometown Ashtarak, Armenia. In 2007 Sisakian's name was added to the List of notable dates of UNESCO. His son, Alexei Sisakian (1944–2010), was a well-known physicist, academic of the Russian Academy of Sciences and Armenian Academy of Sciences, the vice-president of "Dubna" International University, director of the Joint Institute for Nuclear Research in Dubna, Russia.

Worked examples

Example 1 — a first encounter with Norair Sisakian

Start with the simplest possible case. Write down what Norair Sisakian claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Norair Sisakian 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 Norair Sisakian 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 Norair Sisakian

In research: Norair Sisakian appears in chemistry 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 Norair Sisakian 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: Norair Sisakian is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1907 births, 1966 deaths, 20th-century Armenian scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Norair Sisakian 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.
