Jan Greve

Jan Greve 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 Jan Greve rather than just read about it. In short: Jan Greve (?? – 1996) was a Norwegian psychiatrist who is best known for having used cannabis and LSD to treat his patients. In 1972 he was sentenced to one year in prison, of which nine months was probation, and his medical licence was revoked for two years.

Key takeaways

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

Reference excerpt

Jan Greve (?? – 1996) was a Norwegian psychiatrist who is best known for having used cannabis and LSD to treat his patients. In 1972 he was sentenced to one year in prison, of which nine months was probation, and his medical licence was revoked for two years. He resumed his practice following this time. Retrospectively, Greve has stated that he considered the case to be part of a witchhunt where deviations from the mainstream drug policy view was the real enemy.

Worked examples

Example 1 — a first encounter with Jan Greve

Start with the simplest possible case. Write down what Jan Greve 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 Jan Greve 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 Jan Greve 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 Jan Greve

In research: Jan Greve 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 Jan Greve 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: Jan Greve is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1996 deaths, Norwegian prisoners and detainees, Norwegian psychedelic drug advocates, so understanding it makes those chapters shorter.
In everyday life: Look for Jan Greve 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.
