Aryabhatta476-550
*Born in 476 A.D., In kerala.*A renowned mathematician and astronomer of ancient india.
*Studied at the University of Nalanda.*One major work was Aryabhatiya written in 499 A.D.
*The book was based on astronomy,spherical trigonometry,arithmetic,algebra and plane trigonometry.
Aryabhatta
• Pioneer to infer that the earth is spherical and rotates on its own axis,resulting in day and night.
Aryabhatta
Field of Mathematics: *Suggested a formula to calculate areas of triangles and circles.
*First mathematician to give the table of the sines.*”Kuttaka Pulverise” method consisted of breaking problems down into new problems
where coefficients became smaller and smaller with every step.
Aryabhatta
*Created method to find the highest common factor of a and b,also related to fractions.*Gave a table of sins to calculate the values at intervals of 90/24=3 degree
45'*Used a formula for sin (n+1) X-sin nx Sin nx and sin (n-1)x
*Introduced Versine = 1 (Cosine) into trigonometry.
Johannes Kepler1571-1630
*Interested in astronomy at an early age.*Studied to become Lutheran Minister
*Became a professor of mathematics instead.*Kepler's three laws of planetary motion.Which led directly to Newtons laws of Motion.
Sometimes called Founder of modern optics.
Johannes Kepler
• Kepler's Law: Stated that planets move along ellipses.
• He was one of the most important scientists ever.
• Generalized Alhazen's Billiard problem, developed the notion of curvature.
Johannes Kepler
*First to notice the set of Platonic regular solids were incomplete when concave solids are admitted.
*First to prove there are only 13 Archimedean solids.*Proved theorems of geometry.
Johannes Kepler
*Discovered Fibonacci series, applied it to botany.*Noted that the ratio of Fibonacci numbers converge to the Golden Mean.
*Early pioneer in calculus , embraced the idea of continuity.(others avoided due to the Zenos paradoxes.
Johannes Kepler
*His work was an inspiration to Cavalieri. *Developed a theory of logarithms.
*improved Napier's Tables.
Johannes Kepler
• Was a very religious man, found a way to credit God for every discovery he made.
• Did not have a lot of money to support his family.
• Lived in poverty,and died in poverty.
• Never knew fame or fortune.
Agnes Sime Baxter(Hill)1870-1917
• Enrolled in Dal housie University in 1887.
• Courses of Study: Mathematics/Mathematical Physics.
• Received Bachelors degree in 1891
• Received multiple awards on Graduation.
• Sir William Young medal for highest standing in Mathematics and Mathematical Physics.
Agnes Sime Baxter
• Completed Masters degree in 1892 at Dal Housie University.
• 1892-1894 Baxter held fellowship at Cornell University. In Newyork.
• Completion of theses “Abelian Integrals” resume of neumann's
• Became second Canadian women and fourth women on North American Continent to receive Ph.D. In mathematics.
Agnes Sime Baxer
• Born March 18,1870 in Halifax, Nova Scotia.
• Family immigrated to Canada from Scotland.
• Father- Robert Baxter, manager of Halifax Gas light Company.
Agnes Sime Baxter
• Married Dr. Albert Ross Hill on August 20,1896.
• Had two daughters
• There were only 2 other women in class of 24 who were also studying second level mathematics.
• Her performance at University was outstanding.
• First women to graduate with honors.
• Died on March 9,1917 in Columbia Missouri
