Victor Vladimirovich Petryashov

Victor Vladimirovich Petryashov is a astronomy 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 Victor Vladimirovich Petryashov rather than just read about it. In short: Victor Vladimirovich Petryashov (16 March 1956 - 2 July 2018) was a Russian zoologist, carcinologist, hydrobiologist and biogeographer. His scientific research focused on taxonomy and distribution of malacostracan crustaceans, particularly orders Mysida, Lophogastrida and Leptostraca, and marine biogeography and hydrobiology of Arctic, Antarctic and temperate seas of the World, and he published over 120 works.

Key takeaways

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

Reference excerpt

Victor Vladimirovich Petryashov (16 March 1956 - 2 July 2018) was a Russian zoologist, carcinologist, hydrobiologist and biogeographer. His scientific research focused on taxonomy and distribution of malacostracan crustaceans, particularly orders Mysida, Lophogastrida and Leptostraca, and marine biogeography and hydrobiology of Arctic, Antarctic and temperate seas of the World, and he published over 120 works. V.V. Petryashov spent all his professional life in St. Petersburg in the Zoological Institute of the Russian Academy of Sciences. As a senior researcher he also curated the malacostracan crustacean collection of the Zoological Institute.

Worked examples

Example 1 — a first encounter with Victor Vladimirovich Petryashov

Start with the simplest possible case. Write down what Victor Vladimirovich Petryashov claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Victor Vladimirovich Petryashov 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 Victor Vladimirovich Petryashov 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 Victor Vladimirovich Petryashov

In research: Victor Vladimirovich Petryashov appears in astronomy 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 Victor Vladimirovich Petryashov 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: Victor Vladimirovich Petryashov is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1956 births, 2018 deaths, 20th-century Russian zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Victor Vladimirovich Petryashov 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.
