Johann Heinrich Diemer 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 Johann Heinrich Diemer rather than just read about it. In short: Johann Heinrich (Harry) Diemer (7 November 1904 – June 1945) was born in Dronrijp, the Netherlands. His father was the reverend N.

Key takeaways

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

Reference excerpt

Johann Heinrich (Harry) Diemer (7 November 1904 – June 1945) was born in Dronrijp, the Netherlands. His father was the reverend N. Diemer, who served at the Reformed Church at Vijfhuizen. He studied biology at the University of Leiden. He studied the ideas of Abraham Kuyper, Herman Bavinck and Jan Woltjer, and soon became an adherent of Herman Dooyeweerd and D. H. Th. Vollenhoven's Reformational philosophy. He gave much of his free time to the Association for Calvinistic Philosophy; he was secretary to the editorial board for its journal Philosophia Reformata from its inception in 1936. During the Second World War, he became acquainted with the young biology student Jan Lever, the later professor of zoology at the Vrije Universiteit Amsterdam. After the War, Lever spoke highly of Diemer as a biologist and theoretician, and he dedicated his book, Creatie en Evolutie (1956), to Diemer. In January 1945 Diemer was arrested by the Nazis and was sent to the Neuengamme concentration camp. He died in 1945, shortly after having been liberated by the British.

Worked examples

Example 1 — a first encounter with Johann Heinrich Diemer

Start with the simplest possible case. Write down what Johann Heinrich Diemer 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 Johann Heinrich Diemer 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 Johann Heinrich Diemer 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 Johann Heinrich Diemer

In research: Johann Heinrich Diemer 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 Johann Heinrich Diemer 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: Johann Heinrich Diemer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1904 births, 1945 deaths, 20th-century Dutch biologists, so understanding it makes those chapters shorter.
In everyday life: Look for Johann Heinrich Diemer 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.
