#177:Consider A Spherical World
I've always been fascinated by equations
and how deceptively powerful they are
in solving problems like this one.
Imagine you tied a rope around the earth's equator
and then you cut it and added 1M to its length.
If you could somehow suspend the rope above the ground
so that it floated like a ring around the planet,
how big would the gap be between
the rope and the ground?
