Jiří Baum

Jiří Baum is a biology 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 Jiří Baum rather than just read about it. In short: Jiří Baum (20 September 1900 – 1944, Warsaw) was a Czechoslovak zoologist, arachnologist, museum curator, explorer and writer. He served as the collector of the zoological department of the National Museum in Prague and is best known in his field for his 1933 book Through the African Wilderness and his 1935 zoological expedition in the Australian outback.

Key takeaways

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

Reference excerpt

Jiří Baum (20 September 1900 – 1944, Warsaw) was a Czechoslovak zoologist, arachnologist, museum curator, explorer and writer. He served as the collector of the zoological department of the National Museum in Prague and is best known in his field for his 1933 book Through the African Wilderness and his 1935 zoological expedition in the Australian outback. Baum was born in Prague in a business family. His father Josef Baum was a meat trader in Královské Vinohrady while his Františka Baumová was from a farming family in Nadějka. He went to the local grammar school before going to study in a business academy. In 1921 he and a classmate Viktor Mayer applied for a scholarship to the United States of America and he there for further studies. In 1922 he went to Brazil along with his sister Anna and her husband Robert Pollert to establish a farm. On returning he joined the natural sciences faculty at Charles University with a special interest in the arthropods. He travelled to Brazil in 1923-24 and West Africa in 1927 along with Albert Pilát (1903-1974). He fell sick with malaria afterwards. He received a doctorate in 1928 with a thesis on the spiders of Bohemia. Shortly after that he travelled to Malaysia and learned the Malay language. He wrote books for children and several travelogues. He took an interest in languages and learned Arabic, Swahili and Malay. In 1930 he translated a Malay fairy tale in "Pa Belalang". In 1931 he drove across Africa with the sculptor František V. Foit in a Tatra campervan. He took pictures documenting the travel. On his travels across Australia, Baum teamed with Walter Drowley Filmer due to his local expertise with spiders. One species of New-Guinean troglobitic cockroach Nocticola baumi was named in 2021 on honour of Jiří Baum. His last trip was to South Africa in 1938 and on his return he was involved in resistance against the Nazi invasion. He was arrested on June 10, 1943 and was transported to Terezín and later Auschwitz. He died in Warsaw from sepsis. A large collection of his photographs are now in the Archives of the National Museum in Prague.

Worked examples

Example 1 — a first encounter with Jiří Baum

Start with the simplest possible case. Write down what Jiří Baum claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, 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 Jiří Baum 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 Jiří Baum 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 Jiří Baum

In research: Jiří Baum appears in biology 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 Jiří Baum 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: Jiří Baum is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1900 births, 1944 deaths, 20th-century explorers, so understanding it makes those chapters shorter.
In everyday life: Look for Jiří Baum 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.
