AIDS. The likelihood that a mutant protein can slip through unnoticed is small: the spectrometer can tell apart proteins that differ by less than a tenth of a proton mass in weight.

Before July 4, 2012, the Higgs boson mass could only be in the 122 GeV to 130 GeV mass range (units where the proton mass is about 1 GeV, and the W and Z vector bosons are 80 GeV and 90 GeV, respectively).

' In the APS it is OK to discuss whether the mass of the proton changes over time and how a multi-universe behaves, but the evidence of global warming is incontrovertible?

The results from the Tevatron, stemming from the two different experiments, suggest that if the Higgs boson does exist, it would have a mass between 115 and 135 GeV -- about 130 times the mass of the proton.
