Reference excerpt

Karl August Otto Hoffmann (25 October 1853 in Beeskow – 11 September 1909) was a German botanist and a high school teacher in Berlin. Author of Sertum plantarum madagascariensium, the genus Hoffmanniella in the family Asteraceae was named after him by Rudolf Schlechter. The plant genus of Hoffmannanthus (also in the family of Asteraceae was named after him in 2014. He studied mathematics and natural history at the University of Berlin, later performing graduate studies at the University of Göttingen. Beginning in 1877, he taught classes at the Friedrichswerdersches Gymnasium in Berlin. He died in September 1909, following an operation for appendicitis. He donated his impressive herbarium to the Berlin Herbarium. With Georg Carl Wilhelm Vatke, he processed botanical specimens collected by Johann Maria Hildebrandt in Madagascar. He also worked with the Madagascar collections of Christian Rutenberg and the botanical specimens collected by Friedrich Wilhelm Alexander von Mechow and Julius Eduard Teusz in the interior of Angola. He is best known for his investigations of the family Asteraceae, of which he is the binomial author of many species. He provided analyses of Asteraceae specimens collected by Auguste Chevalier in Africa and by Per Karl Hjalmar Dusén in Patagonia and Tierra del Fuego. He made major contributions in Engler and Prantl's Die Natürlichen Pflanzenfamilien involving Asteraceae (806 genera).

Worked examples

Example 1 — a first encounter with Karl August Otto Hoffmann

Start with the simplest possible case. Write down what Karl August Otto Hoffmann 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 Karl August Otto Hoffmann 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 Karl August Otto Hoffmann 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 Karl August Otto Hoffmann

In research: Karl August Otto Hoffmann 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 Karl August Otto Hoffmann 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: Karl August Otto Hoffmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1853 births, 1909 deaths, 19th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Karl August Otto Hoffmann 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.
