  • Girolamo was a highly respected physician and was first to describe typhoid fever.
  • He was also an accomplished gambler and chess player and wrote an early book on probality.
  • He was a remarkable inventor he invented the combination lock, advanced gimbal, and a ciphering tool.
  • He did work in philosophy, geology, hydrodynamics music, he wrote books on medicine and an encyclopedia of natural science.
girolamo cardano publishing equations
GirolamoCardano Publishing Equations
  • He was the first to publish a general solutions to cubic and quartic equations, and first to publish the use of complex numbers in calcutions.
  • Cardano’s Italian colleagues deserve much credit. Ferrrai first solved the quartic.
  • Cardano have been the last great mathematician unaware of negative numbers. His treatment of cubic equations had to deal with ax3- bx+ ax3 – bx= c as two different cases.
leonhard euler 1707 1783
Leonhard Euler 1707 - 1783
  • Euler may be the most influential mathematician who ever lived.
  • He rants #77 on Michael Hart’s famous list of the most Influential Persons in History.
  • Euler found the lovely equation:     Σnp(n) xn = 1 / Πk (1 - xk)
biography
Biography
  • April 1707 – 18 September 1783) was a pioneering
  • Swiss mathematics pioneering physicist mathematical.
  • He made important discoveries in fields as diverse as infinitesimal calculus and graph theory.
  • Euler was a devout Christian who believed in the bible to be insprired the rettung was a primarily and argument.

Hertha Marks Ayrton
  • Hertha was born in Porsea, England in 1854. She changed her first name to Hertha even it was Phoebe. She changed it when she was a teenager.
  • After passing the Cambridge University Examination for Women with honors in English and mathematics, she attended GirtonColloege at Cambridge.
  • She assisted her husband with his experiments in physics and electricity, becoming an acknowledged expert on the subject of the electric arc.

  • During her time at Cambridge, Ayrton constructed a sphygmomanometer (pulse recorder), led the choral society, founded the fire brigade, and with Charlotte Scott , Girton'sfirst wrangler, formed a mathematical club.
  • She successfully completed an external examination and received a B.Sc. degree from the University of London in 1881.
her mathematics and electrical work
Her mathematics and electrical work
  • She also put her mathematical skills to practical use – she taught at Notting Hill and Ealing High School, and was also active in devising and solving mathematical problems, many of which were published in "Mathematical Questions and Their Solutions" from the Educational Times.
  • She was in electrical engineering and physics education and a fellow of the Royal Society.
in the 19 th century
In the 19th Century
  • In the late nineteenth century, electric arc lighting was in wide use for public lighting.
  • Shortly thereafter, Ayrton was elected the first female member of the IEE; she remained the sole female member of the institution until 1958.
  • Ayrton was also the first woman to win a prize from the institution, the Hughes Medal, awarded to her in 1906 in honour of her research on the motion of ripples in sand and water and her work on the electric arc.
in 1902
In 1902
  • Ayrton published The Electric Arc, a summary of her research and work on the electric arc, with origins in her earlier articles from the Electrician published between 1895 and 1896.
  • With this publication her contribution to the field of electrical engineering began to be cemented
