Astrophysicists have been looking for Dark Matter, something invisible but gives extra mass to galaxies since Fritz Zwicky measured the rotation of galaxies in 1930s. And looking for…

"Exact coverage, like the Grail of legend, if approached by any but a perfectlypure and holy frequentist, is borne away and vanishes from sight." Joel Heinrich, CDF internal Note 6438

Just as you thought it was over for 2011, and you proceeded to hung the Higgs mass plots on the christmas tree as a wish for stronger signals next year, ATLAS comes out with a new particle discovery…

I was saddened today upon hearing of the death of Franco Rimondi, a colleague in the CDF experiment. Franco was a professor of physics at the university of Bologna since 1980. His research in…

Have you ever looked at a histogram with the data displayed as counts per bin in the form of points with error bars, and wondered whether those fluctuations and departures from the underlying…

Every year since 1990, I have made a holiday card sending it to friends and family (a list of ~ 50). They have always been nerdy. I try and feature something about the physics I figured out in the…

In the previous blog post we familiarized ourselves with a most remarkable device. A device resulting from 20th century science: Albert's chest of drawers. This chest, although presented as a…

"[...] practically nobody took very seriously the CDF claim (not even mostmembers of the collaboration, and I know several of them), while practically everybody isnow convinced that the Higgs boson…
