A mathematical bug shows us why the 3D universe leads to Murphy's Law

This really is the week for mathematical bugs. First, one beetle showed us why we live in a universe of despair. Now, another shows us that whatever can go wrong, will go wrong...and the more that things can go wrong, the more things will go wrong. See how a bug proves a knotty conjecture. » 12/05/11 7:10am 12/05/11 7:10am
