"We were not yet prepared to claim that we had found a new charged lepton, but we were ready to claim that we had found something new. To accentuate our uncertainty I denoted the new particle by U…

Science Fun With A Hot Drink Here is a most enjoyable physics experiment that anyone can do almost anywhere. You will need: 1 hot drink,1 comfortable chair,1 table or desk. You will not need: 1…

The T2K (Tokai-to-Kamioka) project has tracked their first neutrino, one of the least understood particles in the universe.  The detection of the neutrino as it passed 185 miles from the East to…

We live in an expanding universe. Distant galaxies move away from us, and these galaxies see us moving away from them. If we reverse time and trace back this expansion, it follows that the universe…

One of the few physics measurements that the LHC experiments are already in the position of producing, with the week-worth of proton-proton collision data they have collected last December, is that…

There are twenty-four elementary fermions in the standard model. Sure, they are arranged in a very tidy, symmetrical structure of three families of eight fermions (two leptons and six quarks), which…

It has become a pleasant habit for me to visit Bassano del Grappa every February for a conference on particle physics aimed at high-school students. Thanks to the efforts and the skill of dr. Sergio…

The phenomenon, by which perihelion of elliptical orbital path of a planet appears to rotate around a central body, is known as the precession of the orbital path. Since the precession of mercury’s…

I remember very well the very first meeting of the Heavy Flavour Working Group in CDF that I attended in the summer of 1992. I was a summer student back then, and my understanding of spoken English…

"In 1934, L.E.Kinsler at the California Institute of technology was studying the Zeeman effect as a means for evaluating the charge-to-mass ratio of the electron, e/m. The deduction of e/m from the…
