Another week, another round of physics link-y goodness! On October 23, the Bad Astronomer wished everyone a Happy Mole Day and gave 6.02 x 10^23 reasons to celebrate.

The Financial Times magazine ran a "physics special issue" last weekend; here's a few highlights. Physicists have been lured into the financial market for decades, prized for their insights and data-crunching skills. But in a time of turbulence, flash crashes and high-frequency trading, can they really spot things that others miss?

The recently proposed idea of “black hole firewalls” has physicists questioning some of their most cherished ideas. "The new paper strengthens and simplifies the case for firewalls by sidestepping the issue of entanglement altogether, Marolf says. 'It shows very clearly that some things you might have worried about are red herrings and not relevant to the argument.'"
