Key takeaways

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

Reference excerpt

Jan Cornelis Maria van Hest (born 28 September 1968) is a Dutch scientist of organic chemistry, best known for his research regarding polymersomes and nanoreactors. He currently holds the position of professor of bioorganic chemistry at Eindhoven University of Technology and is scientific director at the Institute of Complex Molecular Systems. Among the awards he has received, he was one of the recipients of the 2020 Spinoza Prize.

Biography Van Hest received his MSc degree in Chemical Engineering with distinction from the Eindhoven University of Technology in 1991. He subsequently obtained his PhD in macro-organic chemistry from the same university in 1996 under the supervision of Bert Meijer. His doctoral thesis 'New molecular architectures based on dendrimers' was awarded the DSM Science and Technology award and the SNS Bank Prijs for best thesis in fundamental engineering sciences. In 1996, van Hest received a NWO Talent stipend for a post-doc position on polypeptide engineering at University of Massachusetts Amherst where he collaborated with professor David Tirrell. He returned to the Netherlands to work at DSM Research in 1997 as researcher and later as group leader. Van Hest was appointed as full professor to set up a group in bioorganic chemistry at Radboud University Nijmegen in 2000. His early career focused on developing self-assembling biohybrid block copolymers. In 2010 he was awarded a VICI grant for research on artificial organelles, and in 2016 he obtained an ERC Advanced grant on artificial endosymbiosis. Van Hest moved to Eindhoven University of Technology in 2016, to chair the bioorganic chemistry group at the departments of Chemical Engineering and Biomedical Technology. He was appointed scientific director of the Institute for Complex Molecular Systems (ICMS) at Eindhoven University of Technology in 2018. To date, van Hest has published over 250 peer-reviewed scientific articles, cited more than 15,000 times and has an h-index of 57.

Honors and awards Van Hest was elected member of the Royal Netherlands Academy of Arts and Sciences in 2019. He was member of The Young Academy of the Royal Netherlands Academy of Arts and Sciences from 2005 to 2011. Additionally, van Hest is an elected Fellow of the Royal Society of Chemistry (FRSC), a visiting fellow of the Chinese Academy of Sciences, a member of the American Chemical Society, the American Association for the Advancement of Science and the Royal Netherlands Chemical Society. Listed are some of the prizes awarded to van Hest:

2020 – Spinoza Prize 2016 – ERC Advanced Grant 2013 – Radboud Education Award 2012 – Gravitation program (co-recipient) 2010 – VICI Award 2007 – TOP Grant 1996 – NWO Talent Stipend 1996 – SNS Bank Prijs 1996 – DSM Science and Technology Award

Professional activities Van Hest served as vice-dean at the Faculty of Science in Nijmegen from 2006 to 2010. He is chairman at the Dutch national postgraduate research school Polymer Technology Netherlands. Van Hest serves as associate editor of Bioconjugate Chemistry. He is furthermore an advisory board member of Macromolecular Bioscience, Journal of Materials Chemistry, and Chemical Science. Van Hest is a co-founder of the companies, Noviotech, Encapson and Future Chemistry and serves on the scientific board at GATT Tech, Euronol Chemical Technology Center.

Worked examples

Example 1 — a first encounter with Jan van Hest

Start with the simplest possible case. Write down what Jan van Hest 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 Jan van Hest 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 van Hest 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 van Hest

In research: Jan van Hest 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 Jan van Hest 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 van Hest is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1968 births, 21st-century Dutch chemists, Academic staff of Radboud University Nijmegen, so understanding it makes those chapters shorter.
In everyday life: Look for Jan van Hest 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.
