Petar Đurković

Petar Đurković 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 Petar Đurković rather than just read about it. In short: Petar Đurković (Петар Ђурковић, 1908–1981) was a Serbian astronomer known for discovering two asteroids in 1936 and 1940, respectively. One is named for the Serbian scientist Milutin Milanković, the other for Zvezdara, the hill in Belgrade where the Belgrade Astronomical Observatory is located.

Key takeaways

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

Reference excerpt

Petar Đurković (Петар Ђурковић, 1908–1981) was a Serbian astronomer known for discovering two asteroids in 1936 and 1940, respectively. One is named for the Serbian scientist Milutin Milanković, the other for Zvezdara, the hill in Belgrade where the Belgrade Astronomical Observatory is located. Asteroid 1555 Dejan, discovered by Fernand Rigaux, was named after Đurković's son (H 137). Đurković was the director of Belgrade Observatory 1965-1970. He was also president of the Astronomical Society Ruđer Bošković, the oldest astronomical society in the Balkans.

Worked examples

Example 1 — a first encounter with Petar Đurković

Start with the simplest possible case. Write down what Petar Đurković 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 Petar Đurković 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 Petar Đurković 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 Petar Đurković

In research: Petar Đurković 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 Petar Đurković 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: Petar Đurković is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1908 births, 1981 deaths, 20th-century astronomers, so understanding it makes those chapters shorter.
In everyday life: Look for Petar Đurković 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.
