Peter Ross is an American radiologist who decides to spend a nice and relaxing holiday in Spain. But when he arrives, he is gently forced to perform an autopsy and place a secret package inside the body. After that his life is a bit hectic, he is beaten, shot, imprisoned, taken to Paris and back to Spain and finally betrayed by everyone\u2026 but alive. I really loved the tone of this book and laughed more than once. It is funny, a bit trashy and everything that can happen to Ross just happens to him. So cool.<\/p>\n\n\n\n
“Well then, the next step in the problem is topological. Topology, as you doubtless know, is the mathematics of shapes. For example, topologists can show that a doughnut and a coffee cup are essentially the same. Both genus 1. You can bend a doughnut into the shape of a coffee cup, that sort of thing. But it can get more complicated” Listened to as an audiobook<\/mark><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Peter Ross is an American radiologist who decides to spend a nice and relaxing holiday in Spain.

“I\u2019m sure.”
Indeed. M\u00f6bius strips, and Klein bottles, solids with only one surface. That sort of thing. Very tricky.”
“A solid with only one surface?”
The professor shrugged. \u201cWhy not?\u201d
Ross nodded. Why not?
\u201cHowever, we don\u2019t deal with such abstruse matters. We are working with network theory, started by Euler almost two hundred years ago with the K\u00f6nigsberg bridges. There was a city with a river which divided the land into thirds. There was also an island in the river. The problem was whether you could cross all the bridges, and never recross any.\u201d
\u201cAnd what happened?\u201d
\u201cEuler proved, mathematically, that it was impossible.\u201d<\/em><\/p>\n\n\n\n
