Reference excerpt

Guelfo Cavanna (27 February 1850, in Ferrara – 18 December 1920, in Florence) was an Italian entomologist.

Biography Cavanna was a teacher at the University of Florence and secretary of the Società Entomologica Italiana from 1875 to 1892. In 1880 he worked on the insect fauna of the then unexplored regions of Vulture and Pollino in southern Italy. Many specialists worked on the insects collected (now in La Specola) and the results were published as Narrazione della escursione fatta al Vulture ed al Pollino nel luglio del 1880 da A. Biondi, C. Caroti e G. Cavanna, pp. 3–30; Parte II. Catalogo degli animali raccolti al Vulture, al Pollino ed in altri luoghi dell’Italia meridionalee centrale, pp. 31–87; Bullettino della Società Entomologica Italiana 14:3-87 and subsequent parts. He was accompanied by the botanist Antonio Biondi (1848-1929). He also wrote a 2 volume student manual entitled Zoologia, ad uso dei ginnasi (Sansoni Editore 1909).

Worked examples

Example 1 — a first encounter with Guelfo Cavanna

Start with the simplest possible case. Write down what Guelfo Cavanna 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 Guelfo Cavanna 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 Guelfo Cavanna 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 Guelfo Cavanna

In research: Guelfo Cavanna 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 Guelfo Cavanna 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: Guelfo Cavanna is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1850 births, 1920 deaths, Academic staff of the University of Florence, so understanding it makes those chapters shorter.
In everyday life: Look for Guelfo Cavanna 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.
