A Mathematical Mosaic

“A Mathematical Mosaic is a collection of wonderful topics from number theory through combinatorics to game theory, presented in a fashion that seventh- and eighth-grade students can handle yet high school students will find challenging.”
–John Cocharo, Saint Mark’s School of Texas, Dallas, TX

Ravi Vakil, Professor of Mathematics at Stanford University, is one of the foremost mathematicians in the world today. He is currently the President of the American Mathematical Society. In his undergraduate years, he placed among the top 5 competitors in the prestigious William Lowell Putnam Mathematical Competition, earning him the top award of “Putnam Fellow” in each year–an achievement matched by only 8 people since its inception in 1938. His stellar performance prompted the San Francisco Chronicle to describe him as “a legend in the world of math competitions.”
A Mathematical Mosaic
In this exciting book, Professor Vakil, develops some powerful problem-solving ideas underpinning the major branches of mathematics and weaves them into a mosaic that reveals their interconnections.
The mathematics is presented at the level of the capable high school mathematics student, but there is much substance for the advanced undergraduate and the intelligent lay reader. You will find this book an invaluable source of enrichment problems and ideas.
The style is informal, friendly, and often humorous. In this book, Professor Vakil profiles ten other mathematics olympiad winners including Noam Elkies, the youngest professor to achieve tenure at Harvard, describing how their lives unfolded a decade or so after their olympiad triumphs.
