L. S. Stepanyan

L. S. Stepanyan is a biology 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 L. S. Stepanyan rather than just read about it. In short: Leo Surenovich Stepanyan (Лео Суренович Степанян) (19 March 1931 – 16 February 2002) was an Armenian ornithologist, best known as the author of the Conspectus of the ornithological fauna of the USSR, a taxonomic work in Russian on birds of the Soviet Union. Leo was born in Yerevan on 19 March 1931, the son of Suren, a family physician, and Julia.

Key takeaways

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

Reference excerpt

Leo Surenovich Stepanyan (Лео Суренович Степанян) (19 March 1931 – 16 February 2002) was an Armenian ornithologist, best known as the author of the Conspectus of the ornithological fauna of the USSR, a taxonomic work in Russian on birds of the Soviet Union. Leo was born in Yerevan on 19 March 1931, the son of Suren, a family physician, and Julia. In 1950 he graduated from Leo High School in Yessentuki and then moved to Lomonosov Moscow State University, where he met G. P. Dementieev and other ornithologists. After his graduation in 1955 he spent two years at the Zoological Museum of the university (Zoological Museum of the Moscow State Lomonosov University – ZMMU), where he met ornithologists from all over the USSR who came to examine the collection. From 1957 he taught zoology and under the guidance of S. P. Naumov and A. V. Mikheev, he and some students made expeditions to the Tien Shan, the Pamirs, the Urals and other regions to collect bird specimens. He published several papers on the results of these collection trips. In 1975 he was invited by the Institute of Evolutionary Morphology and Ecology of Animals and became part of the scientific team that went on the research vessel "Callisto" to the islands of the southwest Pacific. He also made expeditions to Mongolia, Vietnam (eleven expeditions from 1978 to 1990) and North Korea. His major works included the Birds of Vietnam and the Conspectus of the ornithological fauna of the USSR (1990). He died on 16 February 2002.

Worked examples

Example 1 — a first encounter with L. S. Stepanyan

Start with the simplest possible case. Write down what L. S. Stepanyan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 L. S. Stepanyan 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 L. S. Stepanyan 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 L. S. Stepanyan

In research: L. S. Stepanyan appears in biology 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 L. S. Stepanyan 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: L. S. Stepanyan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 2002 deaths, 20th-century Russian biologists, so understanding it makes those chapters shorter.
In everyday life: Look for L. S. Stepanyan 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.
