Hans Höppner

Hans Höppner is a science 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 Hans Höppner rather than just read about it. In short: Hans Höppner (8 February 1873, in Bremen – 24 April 1946, in Krefeld) was a German botanist and entomologist. He worked as a secondary school teacher in the city of Krefeld.

Key takeaways

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

Reference excerpt

Hans Höppner (8 February 1873, in Bremen – 24 April 1946, in Krefeld) was a German botanist and entomologist. He worked as a secondary school teacher in the city of Krefeld. Here, he oversaw the local natural science museum, its herbarium and also worked on the museum's entomological collections. Höppner issued the exsiccata Orchidaceae exsiccatae. Mitteleuropäische Orchideen (1917–1932). Known for investigations of flora native to the Lower Rhine, he also made numerous taxonomic contributions within the botanical family Orchidaceae. In the field of entomology, he published a regional study on bees called Die Bienenfauna der Dünen und Weserabhänge zwischen Uesen und Baden (1901).

Principal works Flora des Niederrheins : zum gebrauch in schulen und afu ausflügen, 1907 - Flora of the Lower Rhine. Flora des Westfälisch-Rheinischen Industriegebietes unter Einschluß der Rheinischen Bucht, 1926 - Flora of the Rhenish-Westphalian industrial area, including the Rhine basin.

Worked examples

Example 1 — a first encounter with Hans Höppner

Start with the simplest possible case. Write down what Hans Höppner 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 Hans Höppner 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 Hans Höppner 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 Hans Höppner

In research: Hans Höppner 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 Hans Höppner 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: Hans Höppner is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1873 births, 1946 deaths, 20th-century German botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Hans Höppner 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.
