Modest Ilyin

Modest Ilyin 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 Modest Ilyin rather than just read about it. In short: Modest Mikhailovich Ilyin or Iljin (Модест Михайлович Ильин; 17 October 1889, Góra Kalwaria - 9 May 1967, Leningrad) was a Russian botanist. He was the keeper of the Herbarium of the Leningrad State University (now the Herbarium of the Komarov Botanical Institute) for many decades.

Key takeaways

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

Reference excerpt

Modest Mikhailovich Ilyin or Iljin (Модест Михайлович Ильин; 17 October 1889, Góra Kalwaria - 9 May 1967, Leningrad) was a Russian botanist. He was the keeper of the Herbarium of the Leningrad State University (now the Herbarium of the Komarov Botanical Institute) for many decades. Ilyin was raised in Krasnoyarsk. Influenced by Arkady Tugarinov (the director of the Krasnoyarsk Museum), he developed an interest in natural sciences, particularly botany. In 1909, he enrolled in the Faculty of Medicine at Tomsk University. There, he attended botanical lectures by Vasily Sapozhnikov (the university's dean). In 1912, Ilyin moved to Saint Petersburg, deciding to continue his studies at Saint Petersburg University. He also worked as an assistant to Boris Fedtchenko and Vladimir L. Komarov at the university herbarium. In 1916, he graduated from Saint Petersburg University and became a curator at the herbarium. Ilyin taught botany at Leningrad University for decades and described a large number of new species from a wide variety of plant families, especially from Central Asia. In 1935, Ilyin was awarded the degree of Doctor of Biological Sciences without defending a dissertation. He was named an Honored Scientist of the RSFSR in 1960. He was buried at the Northern Cemetery in Saint Petersburg. The genus Iljinia and many species of plants were named after him.

Worked examples

Example 1 — a first encounter with Modest Ilyin

Start with the simplest possible case. Write down what Modest Ilyin 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 Modest Ilyin 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 Modest Ilyin 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 Modest Ilyin

In research: Modest Ilyin 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 Modest Ilyin 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: Modest Ilyin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1889 births, 1967 deaths, 20th-century Russian botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Modest Ilyin 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.
