- Letting Go Of The Reality Ether
-
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 gedanken gadget, is real in the sense that devices with the ...

- Holiday card, 2011
-
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 year. This one is less upbeat than those in the past, but t ...

- Those Deceiving Error Bars
-
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 hypothesized model (usually overimposed as a continuous line or ...

- Franco Rimondi, 1944-2011
-
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 particle physics encompasses the last forty years, during which ...

- ATLAS Discovers New Chi_b Resonance
-
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. That's what I like of particle physics- there' ...

- The Basic Idea of the General Theory of Relativity
-
Was Galileo wrong? The answer is no. Then what is special in Einstein's Special Theory of Relativity(STR)? The answer is that in STR, we know about the kinematics of high speed objects. In a certain limit the Lorentz Transformation or Einstein's ...

- My Top 10 Particle Physics Articles Of 2011
-
A blog is by nature a place where things move on fast. Articles disappear beyond the horizon in the matter of a week or two, and only rarely get resuscitated by a later article linking them back from oblivion. At Science 2.0 things are no better than in an ...
