When I was a kid I used to ride the Cyclone at Coney Island. It was an exhilarating experience, but it was always over too soon. So many things in life are like that.
It occurred to me today that if roller coasters were designed by mathematicians, such limitations could be removed. Through the application of some simple principles of geometric topology, I now present, for your consideration, a sketch of a roller coaster mathematically guaranteed to provide an infinite ride.
The fun never has to end. 🙂
