Hilbrand Boschma

Hilbrand Boschma 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 Hilbrand Boschma rather than just read about it. In short: Hilbrand Boschma (22 April 1893 – 22 July 1976) was a Dutch zoologist and director of the Rijksmuseum of Natural History in Leiden. Boschma studied botany and zoology at the University of Amsterdam.

Key takeaways

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

Reference excerpt

Hilbrand Boschma (22 April 1893 – 22 July 1976) was a Dutch zoologist and director of the Rijksmuseum of Natural History in Leiden. Boschma studied botany and zoology at the University of Amsterdam. He went to the former Dutch East Indies, where he studied embryology, functional morphology in reptiles and amphibians, and stony corals. He joined a Danish expedition to the Kai Islands in 1922 as an associate of the Danish zoologist Dr. Th. Mortensen and sampled and studied corals. He is taxon author of (among other invertebrate organisms) several different species of fire corals. Thereafter Boschma went back to The Netherlands to take up the post of chief assistant at the Zoological Laboratory of the State University at Leiden. In 1925 he started giving lectures in general zoology for medical students, and in 1931 he became professor of general zoology. In 1934 Boschma became director of the Rijksmuseum of Natural History in Leiden. He was the first director who was specialized in invertebrate animals. He was also a Member of the Royal Netherlands Academy of Arts and Sciences since 1946, Foreign Fellow of the Zoological Society of London, Honorary Foreign Member of the Société zoologique de France, and member of the International Commission on Zoological Nomenclature. He retired at age 65 in 1958, but continued giving lectures until 1963 and writing scientific articles until 1974. Boschma is commemorated in the scientific names of two species of reptile (Cryptophis boschmai and Draco boschmai), a lobster (Metanephrops boschmai), and a fish (Lophichthys boschmai).

Worked examples

Example 1 — a first encounter with Hilbrand Boschma

Start with the simplest possible case. Write down what Hilbrand Boschma 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 Hilbrand Boschma 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 Hilbrand Boschma 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 Hilbrand Boschma

In research: Hilbrand Boschma 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 Hilbrand Boschma 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: Hilbrand Boschma is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1893 births, 1974 deaths, 20th-century Dutch zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Hilbrand Boschma 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.
