Hans Bos 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 Hans Bos rather than just read about it. In short: Johannes Lukas "Hans" Bos (born 16 June 1950) is a Dutch biochemist and cancer researcher. He has been a professor of physiological chemistry at Utrecht University since 1991.

Key takeaways

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

Reference excerpt

Johannes Lukas "Hans" Bos (born 16 June 1950) is a Dutch biochemist and cancer researcher. He has been a professor of physiological chemistry at Utrecht University since 1991. He is also employed by the University Medical Center Utrecht.

Career Bos was born in Vlaardingen on 16 June 1950. He studied biochemistry at the Vrije Universiteit Amsterdam between 1969 and 1975. In 1980 Bos obtained his title of Doctor at the University of Amsterdam under Piet Borst, with a thesis titled: "Structural analysis of yeast mitochondrial DNA. The region of the 21S ribosomal RNA gene". He then started working under Alex van der Eb at Leiden University. In 1984 Bos started research on Ras mutations. In 1986 Bos became a lector at Leiden University. In 1991 he was appointed professor of physiological chemistry at Utrecht University. In 2013 the Dutch Cancer Society presented an international "Dream Team" on cancer research, the team was led by Bos and Hans Clevers. In 2015 Dutch newspaper de Volkskrant announced that Bos was the Dutch researcher who obtained most funds in the Netherlands during the previous ten years, obtaining over 31 million euro.

Honours and distinctions Bos was elected a member of the European Molecular Biology Organization in 1996. He was elected a member of the Royal Netherlands Academy of Arts and Sciences in 2006. In 2014 Bos won the Josephine Nefkens Prize for Cancer Research.

Worked examples

Example 1 — a first encounter with Hans Bos

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

In research: Hans Bos 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 Hans Bos 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 Bos is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, Academic staff of Utrecht University, Cancer researchers, so understanding it makes those chapters shorter.
In everyday life: Look for Hans Bos 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.
