Vladimír Porubčan

Vladimír Porubčan 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 Vladimír Porubčan rather than just read about it. In short: Prof. RNDr.

Key takeaways

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

Reference excerpt

Prof. RNDr. Vladimír Porubčan, DrSc., (born 1940) is a Slovak astronomer. He is a member of Astronomical Institute of Slovak Academy of Sciences, Department of Interplanetary Matter. His field of interest contains meteors, meteor streams, meteorites, asteroids, and comets. His significant works along with RNDr. Jáh Štohl, DrSc. considerably explained origin of Taurid meteor complex. He made multiple meteor observations and data analyses on forward scatter radar at Modra Observatory and backscatter radar at Ondřejov Observatory. He is also an acting professor at Faculty of Mathematics, Physics and Informatics, Comenius University, Bratislava. Asteroid 6311 Porubčan was named in honour of him.

Worked examples

Example 1 — a first encounter with Vladimír Porubčan

Start with the simplest possible case. Write down what Vladimír Porubčan 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 Vladimír Porubčan 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 Vladimír Porubčan 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 Vladimír Porubčan

In research: Vladimír Porubčan 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 Vladimír Porubčan 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: Vladimír Porubčan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1940 births, European astronomer stubs, European scientist stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Vladimír Porubčan 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.
