Oswaldo Frota-Pessoa

Oswaldo Frota-Pessoa is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Oswaldo Frota-Pessoa rather than just read about it. In short: Oswaldo Frota-Pessoa (30 March 1917 – 24 March 2010) was a noted Brazilian physician, biologist and geneticist. Oswaldo Frota-Pessoa was born in Rio de Janeiro, where he did all his studies, first in natural history at the University of the Federal District, graduating in 1938; and subsequently medicine at the National School of Medicine of University of Brazil, graduating in 1941.

Key takeaways

  • Oswaldo Frota-Pessoa belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Oswaldo Frota-Pessoa to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Oswaldo Frota-Pessoa from memory before moving on to harder problems.

Reference excerpt

Oswaldo Frota-Pessoa (30 March 1917 – 24 March 2010) was a noted Brazilian physician, biologist and geneticist. Oswaldo Frota-Pessoa was born in Rio de Janeiro, where he did all his studies, first in natural history at the University of the Federal District, graduating in 1938; and subsequently medicine at the National School of Medicine of University of Brazil, graduating in 1941. He got his doctoral degree at the same school, in 1953 and soon afterwards went abroad on a scholarship for post-doctoral studies at Columbia University, in New York City, from 1953 to 1955. His teaching and research professional career began in 1942, when he accepted a position of assistant professor at the School of Philosophy, Sciences and Letters of the Federal University of Rio de Janeiro, a post he held until 1958. In that year he accepted a new position at the University of São Paulo, moving to São Paulo City, where he worked until his retirement. He attained a full professorship there in 1978 and was elected an emeritus professor in 1995. In 1964 and 1965 he was a visiting professor at the University of Wisconsin–Madison on a Fulbright Program fellowship. Dr. Frota-Pessoa held many positions, such as: specialist in Science Education of the Pan American Union (Organization of American States) in Washington, D.C. (1955–1956), consultant in Human Genetics for the World Health Organization (1961–1986), director of the Coordination Center of Brazil of the Multinational Program of Genetics of the Pan American Union (1968–1973), director of the Centro de Estudos sobre Currículo para o Ensino de Biologia (CECEB) from 1972 to 1979, president of the Brazilian Society of Genetics (1968–1970) and of the Latin American Association of Genetics (1969–1971), founding member of the Academy of Sciences of the State of São Paulo (1974). He has published more than 130 research papers on genetics and about 500 popularization articles. His main research interests were the systematics of Drosophila, the genetics of human populations, cytogenetics, medical genetics and genetic counseling, and genetics in psychiatry. Dr. Frota-Pessoa was an advocate for biology education and a he was a significant proponent for greater public understanding of science. He taught science and biology in secondary schools in the public education system of Rio de Janeiro from 1939 to 1958. Based on this experience, he wrote one of the first textbooks on biology for secondary education, which became a best-seller and was published in many editions. He published a total of 26 textbooks and 17 guides for science and biology teachers. For this work, he won the UNESCO Kalinga Prize for the Popularisation of Science and the CNPq José Reis Award for the Divulgation of Science. He was also decorated by the Brazilian government with the Great Cross of the Brazilian Order of Scientific Merit and was awarded the 1989 Alfred Jurzikowyski Prize of the Brazilian Academy of Medicine, for relevant basic research for medicine.

Worked examples

Example 1 — a first encounter with Oswaldo Frota-Pessoa

Start with the simplest possible case. Write down what Oswaldo Frota-Pessoa 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 Oswaldo Frota-Pessoa 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 Oswaldo Frota-Pessoa 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 Oswaldo Frota-Pessoa

In research
Oswaldo Frota-Pessoa 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 Oswaldo Frota-Pessoa 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
Oswaldo Frota-Pessoa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1917 births, 2010 deaths, 20th-century Brazilian scientists, so understanding it makes those chapters shorter.
In everyday life
Look for Oswaldo Frota-Pessoa 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.
