I read ArXiv regularly. It's not easy because most of the latest publications of physics go there before print. Apart from pedagogical articles (for teaching purposes), all the articles are aimed at…

Fire a machine gun at a wall with two slits. Look at the pattern bullets make that pass through. The pattern is the sum of two Gaussian curves. Classical physics makes sense. Repeat the exercise…

A particle which flies from a point C to point L in the Earth gravitation should submit to the brachistochrone problem decision.  Well-known that the particle flying in a gravitational field of…

This week's edition of the CMS Times features a short piece by A.Rao,  where some points are made on the issue of correct statistical analysis of high-energy physics data. If you read the piece…

“The vacuum is empty” Richard Feynman According to Dick himself, this was his catchiest motto, but eventually he abandoned it for being as wrong as it sounds right.   There are several…

Dec. 6, Spinning the Interaction Story: Spin 1 (1 of 3)Snarky puzzle Figure out how to represent any quaternion using 3D rotations and one complex number. BackgroundComplex numbers are critical in…

...and people who like sausages, should not ask how they are made. As a member of two large scientific collaborations (CDF and CMS), I enjoy the benefit of seeing lots of scientific publications that…

As discussed in Part 1, analyzing “precognition” discredits everything but the in the eyes of pseudo-skeptic scientism worst: The influence of belief on the quantum probability of finding oneself…

I was going to talk about neutrinos today, as the results of MiniBoone looking at how muon neutrinos mix into electron neutrinos had just been published earlier this week, and wanted to write about…

Elsevier is spamming my mailbox. You would not expect that from a large publishing company who makes money from publishing scientific papers, but that's what happens. I think I am not alone in…
