Reference excerpt

Petrus Cornelis (Piet) de Jong (born 24 March 1938 in Hazerswoude) is a Dutch dendrologist. He was the scientific director of the Utrecht University Botanic Gardens and worked as a researcher at the Station for Nursery Stock at Boskoop. He is considered one of the world authorities on Acer, the maples.

Biography Piet de Jong was born in Bent, a hamlet halfway between Hazerswoude and Zoeterwoude. He was a farmer's son, the oldest in a family of six children. When he was seven, he started growing plants. He went to primary school at Hazerswoude, then to the gymnasium in Leiden. In 1960, he started his studies at Wageningen University and Research Centre - which was called 'Landbouwhogeschool' (Agricultural College) in those days. He got a degree in horticultural plant breeding, with optional courses in (botanical) systematics and phytogeography, plant anatomy and virology. Afterwards, he did biosystematic research on Acer in the Laboratory of botanical systematics and phytogeography. He had been involved in research on the flowering of maples before he got his degree. The maples have always been his great passion. In 1971 he became a researcher at the Institute for Horticultural Plant Breeding (Instituut voor de Veredeling van Tuinbouwgewassen - IVT) in Wageningen. He worked on taxonomic problems in plant breeding research and biosystematic research of lilies. In 1976 he got his PhD with a study on maples. In 1977 De Jong became scientific director of Utrecht University Botanic Gardens. The Von Gimborn Arboretum was part of the gardens in those days. From 1988 to 1997, Piet de Jong was in charge of the practical research on tree growing at the 'Proefstation voor de Boomkwekerij' (Trial station for tree nursery) in Boskoop. After his retirement De Jong is still actively involved with the Von Gimborn Arboretum.

Worked examples

Example 1 — a first encounter with Piet de Jong (dendrologist)

Start with the simplest possible case. Write down what Piet de Jong (dendrologist) 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 Piet de Jong (dendrologist) 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 Piet de Jong (dendrologist) 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 Piet de Jong (dendrologist)

In research: Piet de Jong (dendrologist) 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 Piet de Jong (dendrologist) 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: Piet de Jong (dendrologist) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, 20th-century Dutch botanists, 21st-century Dutch botanists, so understanding it makes those chapters shorter.
In everyday life: Look for Piet de Jong (dendrologist) 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.
