Tristan Needham is the author of the highly original[1] book "Visual Complex Analysis" in which he uses a geometric approach to develop complex analysis (which he says was inspired by Isaac Newton's original geometric approach to ordinary calculus). He was a student of Roger Penrose and is currently a professor of mathematics at the University of San Francisco.

该书的前言里详细地介绍了他读‘自然哲学的数学原理’后受到的启发。

认真读过"Visual Complex Analysis",对自己研究启发很大。
