This book presents glimpses (literally, with one page picture and one page description to each topic) to some selected people/ideas/discoveries/milestones from Mathematics. Inspiring. Someone with a college math/CS background is bound to be enthralled. The most remarkable part of this book is that it never goes deep into any topic, it just gives a flash and then diving deep is up to you. I bought this book for my little sister in mind, but I will keep it myself, see!
