Meeting Abstract

Abstract:

Throughout recorded history, men and women have applied abstract mathematical concepts in their everyday life. Notable examples include zero, pi, negative numbers, square roots and logarithms. Mr. Grant will review the first principles (e.g., 2+3=5), present a brief history of the concepts and show how they led to the discovery of the square root of minus one. He will also describe examples of its everyday using such things as electrical circuits and vibrations.
