"The observed exclusion limit is found from the point where the 95% quantile (dottedline) crosses the median value of the distribution of Q values for the QCD prediction(dashed line). This occurs at…

This might become the title of a series of posts, much like my "say of the week" series. In fact, the Large Hadron Collider is back in operation since earlier this month, and the instantaneous…

Lacking the papers to prove I am a theoretical physicist, I have built something working class: a lunchboxThe box contains Yoplait Yogurt, Del Monte 100 Calorie Mixed Fruit, and White Cheddar Cheese…

The CDF collaboration sent to the preprint arxiv a new paper a few days ago. In it, they report on a measurement of the mass difference of top and anti-top quarks. The result would not be worth…

My blogging output here is scarce this week, because I am spending my time at the NEUTEL 2011 conference in Venice. I am producing some posts summarizing the talks I hear at the conference, together…

A 9.0 magnitude earthquake is equal to about 450 megatons of TNT being set off underground.  Due to the situation at the Daiichi nuclear plant near in Sendai Japan there is much talk of how…

What is a BLEVE? A BLEVE is a Boiling-Liquid Expanding-Vapor Explosion. It is fairly common knowledge that removing the radiator cap of a vehicle with a hot engine will cause the ejection of boiling…

The NEUTEL 2011 conference started today in Venice. Many experiments in neutrino physics will be reporting new results there, and the interest is of course high in the community. Along with a few…

Researchers say they have ruled  the cosmic bubble theory, an alternate theory on the nature of dark energy, after recalculating the expansion rate of the universe to unprecedented accuracy. The…

Third graders enjoy clay and pipe cleaners. It might sound cruel to teach them graduate level graph theory most math Ph.D.’s have not seen, but I might get away with it if I uses the right craft…
