Surfing Electrons And The Computer Of Tomorrow

Physicists have succeeded in taking a decisive step towards the development of more powerful computers; they were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them us ...

Faster Than Light Neutrinos Succumb To Bayesian Method

In 2011, science has been confronted with several high profile awkward situations of having to explain why standard methods like classical significance analysis are acceptable in for example medical studies on the safety of a new vaccine but not when resu ...

Analyzing Actions: Newtonian G (1/3?)

A list of eleven steps to analyzing an action will be presented. I could have added one more, but then people might think I was giving up on my physics addiction. The method will be applied to Newton's theory of gravity in this blog. The Maxwell actio ...

CP Violation In Charm Decays: 3.5 Sigma From LHCb!

Today I wish to briefly discuss a recent important measurement produced by the LHCb collaboration, a measurement of CP violation in the decay of charmed mesons. Before I do, I think I need to explain some details of the LHCb experimental arrangement, becau ...

Guess The Plot: Ellipses

It's been a while since my last "guess the plot" posting. The simple explanation is that I did not happen to run into any fancy graph in the last month or so. Now, today I have one for you to guess, but I must add that I believe it is rather ...

OPERA Confirms: Neutrinos Travel Faster Than Light!!

UPDATE: some technical considerations on the measurement are available in a followup post I wrote after attending a seminar on the new result today. In particular, one startling consideration emerges- if the reading of the 20 MHz Opera clock were off by j ...

For Those Frantically Looking For The OPERA Paper...

The Arxiv apparently messed up and the new OPERA article on the neutrino speed measurement cannot be accessed there yet. However, you can get your copy at this link. You will be prompted for the username and password, and you are invited to use "neuve ...

OPERA Confirms Faster Than Light Neutrinos And Indicates Ultra Superluminal Small Initial Jumps

Fresh results from the OPERA collaboration once more confirm the faster than light neutrinos indicated by MINOS. The new findings, available here, also further strengthen a particular scenario: The neutrinos do not travel with superluminal velocity all th ...

A Few Additional Technicalities On The Opera Measurement

After a more careful reading of the paper, the listening to a seminar on the result, and some discussions, I can share with you a few more details on the Opera measurement. ...

CERNs errors are consistent but they are still wrong; Superluminal Neutrinos and systematic errors.

Here I will give you a rundown of papers that have made it to pre-print which point out these errors.  Much will be written about CERN’s latest numbers, allot of it will not spend much time on “systematic errors”, here are a few examples.   CERN's se ...
