The tirade below (a bit over the top, admittedly, but I'm in the middle of a stressful week) is inspired by a post written today by Chad Orzel in his blog, Uncertain Principles. It is a breath of…

The CaRiPaRo foundation offers 15 grants for students willing to follow a Ph.D. program at the University of Padova (Italy). The winners of these grants will get a (modest, but normal for Italian…

Recent data from BaBar, a high energy physics experiment at SLAC National Accelerator Laboratory (originally Stanford Linear Accelerator Center) may suggest possible flaws in the Standard Model of…

April 24, 24 Steps To The Precession Of The Perihelion Of Mercury Snarky puzzle The only metric that is spherically symmetric and solves the Einstein field equations is the Schwarzschild metric, or…

While Higgs rumors are appearing in blogs of the usual suspects, I cannot comment on those -and I decided it is better if I do not even link them here (I have grown wary of oversensitive reactions in…

With the approach of Summer conferences -most notably, ICHEP, which alone has set a make-or-die deadline for the LHC experiments- physicists in ATLAS and CMS are frantically producing their results…

This G is with us since last centuries. Of course, it is Newton gravitation constant. Traditionally it is written using a capital G, and yes! it is a big G!But this one, every universal constant in…

Two days ago I discussed at ICFP 2012 the most recent results of the CMS experiment at the CERN Large Hadron Collider. In the allotted time of my talk I could only cover few analyses, and I obviously…

Everyone's introduction to quaternions always has the same math one-liner: This blog will dive into an issue that has bothered me for years, namely that the line assume the only coordinate system…

The International Conference on New Frontiers in Physics (ICFP) 2012 started today with a rich program of experimental and theory talks. I should be swimming in the Cretan sea in front of the nice…
