Jan K. S. Jansen

Jan K. S. Jansen 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 Jan K. S. Jansen rather than just read about it. In short: Jan Kristian Schøning Jansen (16 January 1931 – 8 January 2011) was a Norwegian physiologist. He was born in Oslo as a son of professor of medicine Jan Birger Jansen (1898–1984) and Helene Sofie Schøning (1902–1976).

Key takeaways

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

Reference excerpt

Jan Kristian Schøning Jansen (16 January 1931 – 8 January 2011) was a Norwegian physiologist. He was born in Oslo as a son of professor of medicine Jan Birger Jansen (1898–1984) and Helene Sofie Schøning (1902–1976). He was married to Lisbeth Bjørneby from 1954 to 1974 and to Helen Troye from 1981. He finished his secondary education at Berg Upper Secondary School in 1949 and studied at the University of Oslo under his father and Birger Kaada. He specialized in neurophysiology. His early research focused on afferent impulses to the cerebellar hemispheres from the cerebral cortex and subcortical nuclei, using electro-anatomical studies in cats. He took the cand.med. degree in 1955, and in 1957 he took the dr.med. degree with the thesis Afferent impulses to the cerebellar hemispheres from the cerebral cortex and certain subcortical nuclei. An electro-anatomical study in the cat. In 1959 he started studies at the University Laboratory of Physiology in Oxford. He won the Andres Jahre Prize for Young Researchers together with Per Andersen in 1967. He was hired as a docent at the University of Oslo in 1968, worked under Stephen Kuffler and John Nicholls at Harvard University from 1969 to 1970, and was a professor at the University of Oslo from 1979 to 1995. He was a member of the Norwegian Academy of Science and Letters from 1977, and chairman of the Nansen Fund.

Worked examples

Example 1 — a first encounter with Jan K. S. Jansen

Start with the simplest possible case. Write down what Jan K. S. Jansen 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 Jan K. S. Jansen 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 K. S. Jansen 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 K. S. Jansen

In research
Jan K. S. Jansen 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 Jan K. S. Jansen 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 K. S. Jansen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1931 births, 2011 deaths, Academic staff of the University of Oslo, so understanding it makes those chapters shorter.
In everyday life
Look for Jan K. S. Jansen 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.
