Hans Trass

Hans Trass 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 Hans Trass rather than just read about it. In short: Hans-Voldemar Trass (2 May 1928 – 14 February 2017) was an Estonian ecologist and botanist. He was a member of the Estonian Academy of Sciences since 1975 and president of the Estonian Naturalists' Society from 1964 to 1973 and 1985 to 1991.

Key takeaways

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

Reference excerpt

Hans-Voldemar Trass (2 May 1928 – 14 February 2017) was an Estonian ecologist and botanist. He was a member of the Estonian Academy of Sciences since 1975 and president of the Estonian Naturalists' Society from 1964 to 1973 and 1985 to 1991. In 1992, Trass was awarded the Acharius Medal by the International Association for Lichenology. Trass was married to Estonian actress Raine Loo. The couple had a son, composer and organist Toomas Trass. Trass died in Tartu, Estonia, on 14 February 2017, aged 88.

Worked examples

Example 1 — a first encounter with Hans Trass

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

In research: Hans Trass 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 Hans Trass 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 Trass is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1928 births, 2017 deaths, 20th-century Estonian botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Hans Trass 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.
