Gerard of Brussels

Gerard of Brussels (Latin: Gerardus Bruxellensis, nl. Gerard van Brussel, French: Gérard de Bruxelles, s: . Gerard of Brussels ) ( works about 1187-1260 ) was a geometer and philosopher of the early 13th century. His life and career remain in the dark.

Gerard played a role in the development of the kinematics and the measurement of geometric shapes. He was known primarily for his book Liber de motu ( over-travel ), a set of six manuscripts, fundamental work of the kinematics, which was probably built 1187-1260.

He made the works of Euclid and Archimedes popular again and was a creative director of the Oxford Calculators. Thomas Bradwardine cites Gerard in his work Tractatus de proportionibus velocitatum ( 1328 ).

His main contribution was his rejection of the Greek mathematics and the emergence of the idea of the ratio of two unequal quantities such as distance and time, as modern physics defined speed.
