Physics

Third graders enjoy clay and pipe cleaners. It might sound cruel to teach them graduate level graph theory most math Ph.D.’s have not seen, but I might get away with it if I uses the right craft supplies. Tell kids spinach is good for them. Children are right to skeptical, as I expect of my reader.

... Not really.

What startled me most was that a colleague of mine at the University of Padova even sent a message to my departments' mailing list, saying that the new result is very important. But it clearly isn't! In fact, the exclusion at 95% CL in the range of Higgs boson masses that CDF and DZERO could put together from the analysis of additional data is almost exactly the same as the one that they published last Summer.

But maybe I should make a step back and explain the matter from the start, to let you judge by yourself the relevance of the new Tevatron bounds on the rate of Higgs boson production in proton-antiproton collisions.

CDF and DZERO are analyzing the proton-antiproton collisions at 2 TeV that the Tevatron collider is producing since 2001.

Neutrino phyisics may be boring, as Jester claims in a post today at the NEUTEL11 blog, or exciting, as many others are ready to testify. And since Jester talks about exciting new results ready to be submitted by the XENON100 collaboration, I would bet you will concur with the latter.
I define the fringe as anyone trying to make a contribution to a field where they are not employed or do not have a degree in the subject.  I happen to be a fringe physicist because my degrees from MIT were in Biology and Chemical Engineering.  My current job is in software with no connection what-so-ever with physics.

Readers of this blog know that I often discuss here the latest results of searches of Supersymmetric (SUSY) particles -nowadays furthered by the CDF and DZERO experiments at the Fermilab Tevatron collider, and by the ATLAS and CMS experiments at the CERN LHC.

Upon expressing the Higgs potential in terms of the field H0, we find



The first term in V is a constant energy density which can be interpreted as a contribution to the vacuum energy,


Superfluid liquid Helium is shot under very high pressure out of a tiny nozzle and into vacuum. Outside in front of the nozzle, the excess pressure bursts the liquid apart violently into a myriad of fragments. A cloud of ultra small droplets comes into existence. The liquid beam is almost completely atomized.

If you take a randomly drawn droplet from the explosion, the number of atoms inside of it is mostly just one, a single atom. Finding two atoms is less likely, three atoms even less, and so on.

Booze has likely inspired many an action in researchers but any actual science effect was second order.   No more.   Scientists from the National Institute for Materials Science in Japan found that immersing pellets of an iron-based compound in heated alcoholic beverages for 24 hours greatly increase their superconducting ability.

And red wine, which has been shown to have numerous health benefits, is apparently tops in physics experiments as well.
Just a very short post here to mention Marni Dee Sheppeard's guest post in the brand new NEUTEL blog, the blog of the Neutrino Telescopes 2011 conference, which will be held in Venice from March 15th to March 18th, in the beautiful setting of Palazzo Franchetti, on the Grand Canal. Marni discusses the connection between MINOS results and CPT violation.
In a recent post I mentioned here that for the first of two feature articles I wrote for Physics World, and which just appeared in this month's issue (the first piece is actually available online here), I had hand-drawn four sketches that described visually the four main steps of a data analysis looking for new physics.
