Lars Vatten

Lars Vatten is a astronomy 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 Lars Vatten rather than just read about it. In short: Lars Johan Vatten (20 August 1952 - 14 July 2025) was a Norwegian epidemiologist. He did research on cancer, perinatal and cardiovascular epidemiology.

Key takeaways

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

Reference excerpt

Lars Johan Vatten (20 August 1952 - 14 July 2025) was a Norwegian epidemiologist. He did research on cancer, perinatal and cardiovascular epidemiology.

Biography Vatten was born in Trondheim, Norway, studied medicine at the University of Tromsø (he was made MD in 1980) and received a Master of Public Health in 1988 from the University of North Carolina. Two years later the University of Trondheim awarded him a PhD. He initially worked for his internship at the Molde County Hospital from 1980 to 1981 and Sunndal Municipality from 1981 to 1982. After serving at the Royal Norwegian Navy he became a family doctor at the University of Trondheim from 1983 to 1986. After a year of training in occupational medicine he joined the Norwegian Cancer Society as a research fellow 1987-1990. From 1990 to 1996 he worked at the Norwegian Research Council. From 1996, he was professor and chair of the Epidemiology Department at the Norwegian University of Science and Technology in Trondheim. In 1997–2002 he was adjunct lecturer in cancer epidemiology at the Harvard School of Public Health in Boston. He also was professor in epidemiology at the University of Bergen, Norway, 2002–2003 and from 2007 to 2008 he was a senior research fellow at the International Agency for Research on Cancer, Lyon, France. Since 2008 he held an honorary professorship at Bristol University and was a visiting scientist of the Harvard School of Public Health (now Harvard T.H. Chan School of Public Health) from 2009. From 2010 Lars Vatten was also a senior research fellow of the International Prevention Research Institute, Lyon.

Scientific merits Vatten's specific field of research was epidemiological research. He contributed to the fields of cancer, perinatal and cardiovascular epidemiology. He published more than 200 articles in scientific journals and is co-author of some books. Lars Vatten was a member of The Royal Norwegian Society of Sciences and Letters. In 2010 he received King Olav V's Prize for Cancer Research from the Norwegian Cancer Society.

Worked examples

Example 1 — a first encounter with Lars Vatten

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

In research: Lars Vatten appears in astronomy 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 Lars Vatten 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: Lars Vatten is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1952 births, 2025 deaths, Cancer researchers, so understanding it makes those chapters shorter.
In everyday life: Look for Lars Vatten 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.
