Karel Kavina

Karel Kavina 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 Karel Kavina rather than just read about it. In short: Karel Kavina (September 4, 1890 – January 21, 1948, both in Prague) was a Czech botanist. Kavina was professor of botany at the Technical University in Prague.

Key takeaways

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

Reference excerpt

Karel Kavina (September 4, 1890 – January 21, 1948, both in Prague) was a Czech botanist. Kavina was professor of botany at the Technical University in Prague. He worked on systematics, plant morphology and anatomy, and bryology. He published several atlases and monographs and was editor-in-chief of two botanical journals. With Alfred C. Hilitzer he issued the exsiccata Cryptogamae Čechoslovenicae exsiccatae, editae ab instituto botanico Polytechnici Pragense, curantibus Prof. Dr. K. Kavina et Doc. Dr. A. Hilitzer (1933-1937). In 1938, botanist Albert Pilát published Kavinia, which is a genus of fungi in the Lentariaceae family. The genus contains five species, and has a largely European distribution. It was named in Kavina's honour.

Worked examples

Example 1 — a first encounter with Karel Kavina

Start with the simplest possible case. Write down what Karel Kavina 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 Karel Kavina 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 Karel Kavina 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 Karel Kavina

In research: Karel Kavina 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 Karel Kavina 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: Karel Kavina is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890 births, 1948 deaths, 20th-century Czech botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Karel Kavina 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.
