Manfred Donike

Manfred Donike is a chemistry 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 Manfred Donike rather than just read about it. In short: Manfred Donike (23 August 1933, Köttingen, Rhine Province – 21 August 1995, on a flight from Frankfurt am Main to Johannesburg) was a German cyclist and chemist, known for his research on doping. Donike lived in Rölsdorf.

Key takeaways

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

Reference excerpt

Manfred Donike (23 August 1933, Köttingen, Rhine Province – 21 August 1995, on a flight from Frankfurt am Main to Johannesburg) was a German cyclist and chemist, known for his research on doping. Donike lived in Rölsdorf. Donike studied chemistry in Cologne and graduated in 1965. By 1972, Donike had developed a procedure capable of accurate detection of banned substances and their metabolites through analysis, using gas chromatography and mass spectrometry, of urine. In 1977, Donike was hired by the German Sport University Cologne to lead the biochemistry department. In 1960 and 1961, Donike competed in the Tour de France. His son, also called Manfred, competed at the 1984 Summer Olympics. Donike died of a heart attack on 21 August 1995 in an aeroplane while en route to Johannesburg, South Africa.

Worked examples

Example 1 — a first encounter with Manfred Donike

Start with the simplest possible case. Write down what Manfred Donike claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, 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 Manfred Donike 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 Manfred Donike 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 Manfred Donike

In research: Manfred Donike appears in chemistry 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 Manfred Donike 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: Manfred Donike is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1933 births, 1995 deaths, 20th-century German chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Manfred Donike 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.
