Maurício Peixoto
Maurício Matos Peixoto, (April 15, 1921, in Fortaleza, Ceará – April 28, 2019, in Rio de Janeiro), was a Brazilian engineer and mathematician. He pioneered the studies on structural stability, and was the author of Peixoto's theorem. Biography Once, while talking with his mentor, Solomon Lefschetz, Maurício Peixoto commented that no one cared about structural stability of dynamical systems and that was the main problem in working with it. But to Peixoto's surprise Lefschetz's answer was no less than "No Mauricio, this is no trouble, this is your luck. Try to work as hard and as fast as you can on this subject because the day will come when you will not understand a single word of what they will be saying about structural stability; this happened to me in topology." Lefschetz's support was very important to Peixoto at the time. In 1957, Peixoto went to research the subject with Lefschetz at the Princeton University, where he spent uncountable hours talking to the Russian pro ...

Steve Smale
Stephen Smale (born July 15, 1930) is an American mathematician, known for his research in topology, dynamical systems and mathematical economics. He was awarded the Fields Medal in 1966 and spent more than three decades on the mathematics faculty of the University of California, Berkeley (1960–1961 and 1964–1995), where he currently is Professor Emeritus, with research interests in algorithms, numerical analysis and global analysis. Education and career Smale was born in Flint, Michigan and entered the University of Michigan in 1948. Initially, he was a good student, placing into an honors calculus sequence taught by Bob Thrall and earning himself A's. However, his sophomore and junior years were marred with mediocre grades, mostly Bs, Cs and even an F in nuclear physics. However, with some luck, Smale was accepted as a graduate student at the University of Michigan's mathematics department. Yet again, Smale performed poorly in his first years, earning a C average as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
People From Fortaleza
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness Consciousness, at its simplest, is sentience and awareness of internal and external existence. However, the lack of definitions has led to millennia of analyses, explanations and debates by philosophers, theologians, linguisticians, and scien ... or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal obligation, legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they w ...

Peixoto was the first Brazilian woman to receive a doctorate in mathematics and the first Brazilian woman to join the Brazilian Academy of Sciences. Early life and education Marília Magalhães Chaves was born on 24 February 1921, to Tullio de Saboia Chaves and Zillah da Costa Magalhaes, in Santana do Livramento. She had two siblings, Lúcia de Magalhaes Chaves and Livio de Magalhaes Chaves. In an interview from 1952, she would describe her educational upbringing, stating that despite the high school in Santana do Livramento not accepting girls as students, the priests helped her enroll as a private student and take tests in the school. She later moved to Rio de Janeiro, studying at the Colégio Andrews, a secular school that allowed boys and girls to study. She graduated as an outstanding student. She studied superior courses and studied for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TWAS
The World Academy of Sciences (TWAS) is a merit-based science academy established for developing countries, uniting 1,000 scientists in some 70 countries. Its principal aim is to promote scientific capacity and excellence for sustainable development in developing countries. It was formerly known as the ''Third World Academy of Sciences''. Its headquarters is located on the premises of the Abdus Salam International Centre for Theoretical Physics (ICTP) in Trieste, Italy. History TWAS was founded in 1983 under the leadership of the Nobel Laureate Abdus Salam of Pakistan by a group of distinguished scientists who were determined to do something about the dismal state of scientific research in developing countries. * Although developing countries account for 80% of the world's population, only 28% of the world's scientists hail from these countries. This fact reflects the lack of innovative potential necessary to solve real-life problems affecting poor nations. * A chronic lack of ...

René Thom
René Frédéric Thom (; 2 September 1923 – 25 October 2002) was a French mathematician, who received the Fields Medal in 1958. He made his reputation as a topologist, moving on to aspects of what would be called singularity theory; he became world-famous among the wider academic community and the educated general public for one aspect of this latter interest, his work as founder of catastrophe theory (later developed by Erik Christopher Zeeman). Life and career René Thom grow up in a modest family in Montbéliard, Doubs and obtained a Baccalauréat in 1940. After German invasion of France, his family took refuge in Switzerland and then in Lyon. In 1941 he moved to Paris to attend Lycée Saint-Louis and in 1943 he began studying mathematics at École Normale Supérieure, becoming agrégé in 1946. He received his PhD in 1951 from the University of Paris. His thesis, titled ''Espaces fibrés en sphères et carrés de Steenrod'' (''Sphere bundles and Steenrod squares''), was w ...
