Sometimes gravity can be a pain in the heel,Harvard physics professor Lisa Randall tells John CraceTwo years after her climbing accident, Lisa Randall shakes her head, and still not fairly able to accept the reality of the laws of physics. "It just shouldn't have happened," she says. "I was climbing safely, the conditions were noble, and the route wasn't that difficult and I was properly roped up. But somehow,I managed to fall and smash my heel."It sounds like a straightforward, Newtonian case of "what goes up, or must near down",but whenever Randall gets stuck into the laws of physics - and gravity in particular - things rarely turn out to be as simple as you imagined they would.
