Written to engage and enthuse young minds, this accessible overview introduces readers to the amazing people who figured out how shapes work and how they can be used to build spaces and study places we cannot go, like the beginning of the Universe. Filled with enlightening illustrations and images, Geometry is arranged chronologically, from Euclid's revolution to the Poincar conjecture, to clearly show how ideas in mathematics evolved from the Ancient Egyptians in 3000 BC to the present day. What began as scratched circles and squares in the dirt has evolved into a branch of mathematics used to create realistic landscapes in video games, build mile-high skyscrapers, and manufacture robots so tiny they can swim in your bloodstream.
