Reference excerpt

Haroldo Pereira Travassos (23 March 1922 - 13 June 1977) was a Brazilian ichthyologist. He taught at the La-Fayette Institute, the Fluminense Federal University, and the Federal University of Rio de Janeiro. Travassos was born in Rio de Janeiro, the son of the helminthologist Lauro Pereira and his wife Odette. He grew up in the city and went to the National School of Veterinary Medicine where he graduated in 1944 and received a medical degree in 1945. He worked with his father both in the field and laboratory and became a naturalist at the National Museum becoming a professor in 1969. He began to specialize in the fishes and became a director of fisheries development in 1966. As a fish taxonomist, he specialized in the families Characidae, Cichlidae and Sciaenidae.

Worked examples

Example 1 — a first encounter with Haroldo Pereira Travassos

Start with the simplest possible case. Write down what Haroldo Pereira Travassos 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 Haroldo Pereira Travassos 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 Haroldo Pereira Travassos 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 Haroldo Pereira Travassos

In research: Haroldo Pereira Travassos 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 Haroldo Pereira Travassos 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: Haroldo Pereira Travassos is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1922 births, 1977 deaths, Academic staff of Fluminense Federal University, so understanding it makes those chapters shorter.
In everyday life: Look for Haroldo Pereira Travassos 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.
