Cramer, Gabriel Gabriel Cramer, suizo, trabajó en Análisis y determinantes. Llegó a ser profesor de matemáticas en Ginebra, escribió un trabajo donde relataba la física, también en geometría y la historia de las matemáticas. Cramer es más conocido por su trabajo en determinantes, pero también hizo contribuciones en el estudio de las curvas algebraicas (1750).

9. Gabriel Cramer Gabriel Cramer 17041752 Gabriel Cramer certainly moved rapidly throughhis education in Geneva, and in 1722 while he was still http://www.stetson.edu/~efriedma/periodictable/html/Cm.html

Gabriel Cramer As part of his appointment, Cramer did lots of travelling. He visited leading mathematicians in many different cities and countries of Europe. He headed straight away for Basel where many leading mathematicians were working, spending five months working with Johann Bernoulli, and also Euler who soon afterwards headed off to St. Petersburg to be with Daniel Bernoulli. Cramer then visited England where he met Halley, de Moivre, Stirling, and other mathematicians. From England, Cramer made his way to Paris where he had discussions with Fontenelle, Maupertuis, Buffon, Clairaut, and others. His discussions with these mathematicians and the continuing correspondence with them after he returned to Geneva had a big influence on Cramer's work. Back in Geneva in 1729, Cramer was at work on an entry for the prize set by the Paris Academy for 1730. Cramer's entry was judged as the second best of those received by the Academy, the prize being won by Johann Bernoulli. In 1734, Calandrini was appointed to the chair of philosophy and Cramer became the sole holder of the Chair of Mathematics. Cramer lived a busy life, for in addition to his teaching and correspondence with many mathematicians, he produced articles of considerable interest, although these are not of the importance of the articles written by most of the top mathematicians with whom he corresponded. He published articles covering a wide range of subjects including the study of geometric problems, the history of mathematics, philosophy, and the date of Easter. He published an article on the aurora borealis, and one on law where he applied probability to demonstrate the significance of having independent testimony from 2 or 3 witnesses rather than from a single witness.

Biografías Historia de la Matemática Biografías Temas Curiosidades ... Libro de visitas Cramer Gabriel (1704-1752) Matemático Suizo. Aunque Cramer no está considerado al lado de los grandes matemáticos de su tiempo, sus contribuciones como diseminador de las ideas matemáticas le ganaron un bien merecido lugar en la historia de las matemáticas. Cramer viajó bastante y conoció a muchos de los grandes matemáticos de su época. Estos contactos y amistades condujeron a una correspondencia abundante a través de la cual se difundía la información sobre nuevos descubrimientos matemáticos. El trabajo más conocido de Cramer, "Introduction á l'analyse des lignes courbes algébriques" (1750), es un estudio y una clasificación de curvas algebraicas; la regla de Cramer apareció en el apéndice. Aunque la regla lleva su nombre, variantes de la idea básica fueron planteadas antes por otros matemáticos. Sin embargo, la notación superior de Cramer ayudó a aclarar y popularizar la técnica. El exceso de trabajo, combinado con una caída de un carruaje, provocaron su fallecimiento en 1752. Aparentemente, Cramer era una persona de buen corazón y agradable, aunque nunca contrajo matrimonio. Sus intereses eran amplios. Escribió sobre filosofía de las leyes y del gobierno, y sobre la historia de las matemáticas. Trabajó en una oficina pública, participó en la artillería y en actividades de fortificaciones para el gobierno, instruyó a trabajadores sobre técnicas de reparación de catedrales y efectuó excavaciones de archivos catedralicios. Cramer recibió numerosos honores por sus actividades.
