Reference excerpt

Sir David de Villiers Graaff, 3rd Baronet (3 May 1940 – 24 January 2015), was a South African businessman and owner of De Grendel Wine Estate. The son of Sir De Villiers Graaff, 2nd Baronet, he was born in 1940, after his father left to serve in the North African Campaign. Sir De Villiers became a prisoner of war in 1942, and would not meet his son until 1945. David took his undergraduate degree BSC Agric University of Stellenbosch, preparatory to a career in politics and farming, but also read politics, philosophy and economics at Magdalen College, Oxford and studied at the University of Grenoble. Like his father, he entered South African politics and served as the National Party Minister of Parliament for the Wynberg constituency in the late 1980s and Deputy Minister of Trade and Industry under FW De Klerk. He retired from Parliament after the 1999 general election. When he inherited the baronetcy and the family estate of De Grendel upon his father's death, he decided to experiment with viticulture and winemaking. Sir David was a director of Graaffs Trust and The Milnerton Estates Limited. He was the Honorary Colonel of the Cape Garrison Artillery until his death on 24 January 2015.

Sir David is survived by his wife Sally and his four children, the eldest of whom, De Villiers, succeeded him in the baronetcy and farming at De Grendel Estate.

Worked examples

Example 1 — a first encounter with Sir David Graaff, 3rd Baronet

Start with the simplest possible case. Write down what Sir David Graaff, 3rd Baronet 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 Sir David Graaff, 3rd Baronet 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 Sir David Graaff, 3rd Baronet 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.
