Did the Babylonians Know the Secant Method in 1-D? (Higher Education Session)

Speaker: Joanna Papakonstantinou (Rice University)

Many believe that the secant method arose out of using a finite-difference approximation of the derivative in Newton's method. The speaker will present a historical development of the secant method in 1-D beginning with examples from the 18th century B.C.

12:30pm - 1:30pm

Historical Topics from Number Theory  (6-8 Session)

Speaker: Marian C. Fox (Kennesaw State University)

12:30pm - 1:30pm

Math's Magical Numbers (3-5 Session)

Speaker: Nancy Jean Budner (Central Washington University)

We will examine the properties of the magical numbers 0 and 1, two of the most historically important and yet misunderstood concepts in mathematics. They are so essential that both teachers and students must be aware of their significance.
