Tracing the development of mathematics from a biographical standpoint, Mathematics Frontiers, Updated Edition profiles innovators from the second half of the 20th century who made significant discoveries in both pure and applied mathematics. The 10 mathematicians in this updated edition exemplify a growing diversity within the mathematical community, drawing from the talents of individuals across all nationalities, races, and genders. From John H. Conway, who helped complete the classification of all finite groups (and invented "The Game of Life" board game), to Stephen Hawking, who established the mathematical basis for black holes, to Fan Chung, who developed an encoding and decoding algorithm for phone calls, this lively survey of contemporary minds behind the math is ideal for middle and high school students seeking resources for research or general interest.
