Reference excerpt

Henk Tennekes (21 November 1950 – 7 July 2020) was a Dutch toxicologist. Tennekes worked as doctor and researcher at the Philipps-Universiteit Marburg; the German research cancer centre Krebsforschungszentrum in Heidelberg; Sandoz in Muttenz, Switzerland and at the Research and Consulting Company in Itingen. Since 1992 he was an independent researcher. Tennekes was born in Zutphen. He studied between 1968 and 1974 and earned his PhD in 1979 at the Wageningen University and Research with the thesis The Relationship between Microsomal Enzyme Induction and Liver Tumour Formation". Tennekes wrote in 2010 the book "A disaster in the making", about the dangers of neonicotinoids, a new generation of pesticides for insects and bees in particular. He discovered that Bayer had researched the effects of neonicotinoid on flies back in 1991, and that the effect was irreversible. Bayer nowadays claims the contrary. Initially, his vision had strong opposition as his findings were criticized, but follow-up research partially confirmed his warning. Since the end of 2018, the use of three neonicotinoids (clothianidin, thiamethoxam and imidacloprid) has been banned in the European Union. Tennekes who used to work as a freelance researcher for chemical companies found himself blacklisted, and lost all his clients, but that didn't deter him, because he considered it his moral duty. Tennekes was suffering from a rare pulmonary disease, and opted for euthanasia. He died on 7 July 2020, aged 69.

Worked examples

Example 1 — a first encounter with Henk Tennekes (toxicologist)

Start with the simplest possible case. Write down what Henk Tennekes (toxicologist) 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 Henk Tennekes (toxicologist) 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 Henk Tennekes (toxicologist) 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 Henk Tennekes (toxicologist)

In research: Henk Tennekes (toxicologist) 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 Henk Tennekes (toxicologist) 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: Henk Tennekes (toxicologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, 2020 deaths, 2020 suicides, so understanding it makes those chapters shorter.
In everyday life: Look for Henk Tennekes (toxicologist) 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.
