In total, some 27 million Americans are believed to be PTSD survivors. Yet to many of us, the disorder remains shrouded in mystery, secrecy, and shame.

On July 4, 2012, the announcement came that one of the longest-running mysteries in physics had been solved: the Higgs boson, the missing piece in understanding why particles have mass, had finally been discovered.
