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

• 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.

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.
