LHC Combination Of Higgs Limits: MH <141 GeV

Totally overshadowed by the news of the new Opera measurement of neutrino speeds, yesterday CERN officially released the combined result of ATLAS and CMS searches for the Higgs boson. The news has been given already in two prominent particle physics blogs ...

Neutrino Faster Than Light Propulsion, not so fast.

If neutrinos can move faster than light (FTL) it does not provide a means for FTL propulsion.  In the last many days I have seen much written about the possibilities that faster than light (FTL) neutrinos would open up.  One popular discussion is of " ...

Square Root Of A Supernova

Supernovas are by far the most violent phenomena in the universe. Would the full energy released in a supernova explosion be directed to earth, the result would be the ultimate carpet bombing. Carpet bombing in full 3D that is. Every single gram of earth, ...

The Puzzling Weighted Average

For you today here is a test of whether you shoud trust your intuition when confronted with an apparently simple problem. Incidentally, this article is the answer to the "Guess The Plot" riddle I posted a few days ago here. Suppose you are given ...

Begging The Question On Faster Than Light Particles: Not Tachyons With Imaginary Mass

There is a widespread misconception which is repeated often these days in the aftermath of the OPERA collaboration’s confirmation of faster than light neutrinos. The misconception is easily stated: “Tachyons, if they actually exist, have imaginary mass, … ...

Analyzing Actions: EM (2/3?)

Newtonian gravity binds us to this rock, while EM presents us with the messages from the heavens. The math of the EM is heavenly compared to Newtonian gravity. Let's review some of the flaws in that old but still useful approach to gravity. ...

Multi-Muons In CDF: The Mystery Continues

Do you remember the multi-muon anomaly in CDF? The matter was discussed with quite some detail in a series of posts in this blog (back then at wordpress). In a nutshell, CDF could not explain their sample of events containing two muons, when these particle ...

UFOs Causing Problems at the Large Hadron Collider (LHC)

UFOs or ‘Unidentified Falling Objects’ have apparently been causing problems in the form of mysterious rapid beam dumps at the Large Hadron Collidor (LHC). It is not yet known definitely what is causing these UFOs and even exactly what they are. One as yet ...

Padova Loses Milla

Sadly, this morning Milla Baldo Ceolin passed away. Milla was a volcanic physicist, and a fantastic professor. I had the pleasure of following her course of "Fisica Superiore" in the late eighties, and I remember her brilliant lessons, insightful ...

Testing OPERA with Nuclear flare: A simple race between anti-neutrinos and photons.

If we can produce neutrinos at the same time as photons,then detect which arrives first the question of neutrino speed vs light speed would be settled.     CERN – OPERA measured neutrinos arriving faster than light would have, astronomers have measured ne ...
