Joost Manassen is a chemistry 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 Joost Manassen rather than just read about it. In short: Joost Manassen (Hebrew: יוסט מנסן; 17 February 1927 – October 2019) was a Dutch-Israeli chemist who was a professor at the faculty of chemistry of the Weizmann Institute of Science. Career Manassen was born on 17 February 1927 in Amersfoort.

Key takeaways

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

Reference excerpt

Joost Manassen (Hebrew: יוסט מנסן; 17 February 1927 – October 2019) was a Dutch-Israeli chemist who was a professor at the faculty of chemistry of the Weizmann Institute of Science.

Career Manassen was born on 17 February 1927 in Amersfoort. During World War II he went into hiding from the Nazis on a farm in North Holland. In 1959 he obtained his PhD at the University of Amsterdam under Professor F.L.J. Sixma with a thesis titled, "Reactions of the n-butenes and 2-butanol in dilute acid solution : a mechanistic study". Manassen moved to Israel and started working for the Weizmann Institute of Science. In the 1970s, after the 1973 oil crisis, Manassen worked on alternative energy based on solar power. In 1983 he became head of the Department of Materials Research. Manassen died in Rehovot in October 2019. Manassen was elected a corresponding member of the Royal Netherlands Academy of Arts and Sciences in 1986.

Worked examples

Example 1 — a first encounter with Joost Manassen

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

In research: Joost Manassen appears in chemistry 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 Joost Manassen 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: Joost Manassen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1927 births, 2019 deaths, 20th-century Dutch chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Joost Manassen 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.
