Lai Ye! Ba Dian Chai Kai!

The geometry you were taught begins with a point. A point has no length, no width, no thickness. It is something no one can picture.

And the whole building of modern science rests on it. A particle is a point. A singularity is a point. So is a city on a map and a star on a chart.

For thousands of years almost no one has taken it apart.

This book takes it apart with six questions: What is inside a point? What is a point made of? How can there be two different kinds of "1"? How did a point become a universe? Did

I come out of a point? And what can you do with a point once it is open?

Along the way: rainbows, the pinhole a compass leaves behind, a basin of water, two mirrors facing each other, a folded sheet of paper, a concert hall - and the hole in your

own eye you have never noticed.

This book does not give you answers. Your textbook already has those.

It gives you another angle.
