Reference excerpt

Gualtherus Carel Jacob Vosmaer (Oud-Beijerland, August 19, 1854 - Leiden, September 23, 1916 ) was a Dutch zoologist.

Biography GCJ Vosmaer was born in 1854 in Oud-Beijerland, where his father, the poet and critic Carel Vosmaer was then a clerk at the subdistrict court. He studied in The Hague and subsequently at the University of Leiden, where he obtained his doctorate in 1880 with a thesis on sponges ("Leucandra aspera and the Canal System of Sponges"). In 1882 he became Anton Dohrn's assistant at his zoological station in Naples. In 1889 he returned to the Netherlands and became assistant to Professor Ambrosius Hubrecht in Utrecht. Later he became a private teacher and lecturer in Utrecht and in 1904 he became professor of zoology in Leiden.

Work Vosmaer was a specialist in the field of sponges, describing many species. In Naples he examined the sponges in the Bay of Naples. He also described the sponges collected during the Willem Barents expedition to the North Atlantic and Arctic Ocean in 1880-1881 and during the Siboga expedition of 1899-1900. The genus Vosmaeropsis Dendy, 1893, is named for him.

Worked examples

Example 1 — a first encounter with Gualtherus Carel Jacob Vosmaer

Start with the simplest possible case. Write down what Gualtherus Carel Jacob Vosmaer claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Gualtherus Carel Jacob Vosmaer 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 Gualtherus Carel Jacob Vosmaer 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 Gualtherus Carel Jacob Vosmaer

In research: Gualtherus Carel Jacob Vosmaer appears in science 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 Gualtherus Carel Jacob Vosmaer 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: Gualtherus Carel Jacob Vosmaer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1854 births, 1916 deaths, 19th-century Dutch zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Gualtherus Carel Jacob Vosmaer 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.
