Reference excerpt

James Walter Grimes, known as Jim Grimes, is an American botanist.

Career Grimes can be attributed to over 240 taxa names, either as sole author or co-author. Grimes worked at the New York Botanical Garden studying Fabaceae. In 1996 Grimes moved to Australia, taking up a position in the National Herbarium of Victoria, Royal Botanic Gardens Victoria as Mueller Fellow July–October 1996, where he worked on developmental morphology of inflorescences in Acacia. From July 1997 to his resignation in February 2002, Grimes was in the position of Systematic Botanist. His research interests included the systematics of Fabaceae, subfamily Mimosoideae, and the historic collections held in the Herbarium. Grimes was co-organiser of the 2001 Legumes Down Under conference. He served as Taxonomic Co-ordinator for legume tribes Ingeae and Psoraleeae for the International Legume Database and Information Service (ILDIS) 2000–2, and as Councillor of the Society of Australian Systematic Biologists 2001–2. Grimes was Editor of Muelleria from 1997 to 2001 A significant number, over 1000 collections, are held at NY. MEL holds over 300 specimens collected by Grimes. Other herbaria in Australia holding his collections include MELU, CANB, NSW, HO, ATH, AD, and BRI.

Worked examples

Example 1 — a first encounter with James Walter Grimes

Start with the simplest possible case. Write down what James Walter Grimes 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 James Walter Grimes 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 James Walter Grimes 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 James Walter Grimes

In research: James Walter Grimes 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 James Walter Grimes 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: James Walter Grimes is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, 20th-century American botanists, 21st-century American botanists, so understanding it makes those chapters shorter.
In everyday life: Look for James Walter Grimes 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.
