Reference excerpt

João Geraldo Kuhlmann (1882 Blumenau, Santa Catarina -1958 Rio de Janeiro, Rio de Janeiro) was a Brazilian botanist.

Life Kuhlmann was a specialist on taxonomy of angiosperms. He was a great collector of herborized material (his collection was gathered at a museum - Botanical Museum Kuhlmann, created in 1960, later the Botanical Museum of the Botanical Garden of Rio de Janeiro opened to the public on September 20, 1991, incorporated this collection of the Kuhlmann Museum ) and notable connoisseur of the Brazilian Flora, influencing a large number of researchers in this area of the knowledge in Brazil, for example William Rodrigues. He published about eighty works, describing new genera (see below), and species. He also erected two families. He put Peridiscus in a family by itself in 1950. Peridiscaceae has since been expanded to include Medusandra, Soyauxia, and Whittonia. He also put Duckeodendron into its own family, Duckeodendraceae, but this, and other segregates of Solanaceae are no longer recognized as separate families by APG. In 1944 he became the director of the Rio de Janeiro Botanical Garden, exerting this function up to 1951. J. G. Kuhlmann created the Botanical Society of Brazil. The genera Kuhlmannia J.C.Gomes, synonym of Pleonotoma,(in the family of Bignoniaceae) and Kuhlmaniella Barroso, synonym of Dicranostyles, (in Convolvulaceae family) and also Kuhlmanniodendron (from Brazil), described in 2008 by Fiaschi & Groppo in the family of Achariaceae are named in his honour.

Worked examples

Example 1 — a first encounter with João Geraldo Kuhlmann

Start with the simplest possible case. Write down what João Geraldo Kuhlmann 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 João Geraldo Kuhlmann 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 João Geraldo Kuhlmann 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 João Geraldo Kuhlmann

In research: João Geraldo Kuhlmann 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 João Geraldo Kuhlmann 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: João Geraldo Kuhlmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1882 births, 1958 deaths, 20th-century Brazilian botanists, so understanding it makes those chapters shorter.
In everyday life: Look for João Geraldo Kuhlmann 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.
