OPERA head resigns

What? It links to a sleeping bag.

Oh ffs! Clipboard shenanigans. Fixed.

He must've fixed it, ma Ftiafpi. For me it links to the BBC article about the resignation.

[Ftiafpi]

Looks like a comfy sleeping bag.

I don't think he should have resigned. Honest mistakes were made and it's not like he made any ridiculous claims before the results were verified. Heck, if anything it caused some brief entertainment and excitement for us science nerds.

OPERA head resigns

I don't think he should have resigned. Honest mistakes were made and it's not like he made any ridiculous claims before the results were verified. Heck, if anything it caused some brief entertainment and excitement for us science nerds.

Pushing for resignation is a political move, not a scientific one. I think the managers of the facility were more concerned about their public reputation than the results of the experiment.

Prof Antonio Ereditato put everything out there for peer review. There wasn't a mistake in that approach, just an inability to change the results of the testing using the instrumentation at hand.

What I would like to know more about, is just how precise the other verification steps were, and what was the actual measurement misstep that cause a perceived flaw in the results.

I am not inclined to accept one test said "this is so" so there. I do wan't to know what makes one test more authoritative than another, and prevailing opinion is not going to cut it for me as justification.

Have I been left out of loop of this thread, or are you all aware that they discovered the error and it turned out to be a measurement error? Apparently as a result of an incorrectly placed tube. That's what I've been told, although, it may not be true.

[Ftiafpi]

Yes, it was an error, hence why the OPERA head has resigned.

I don't know all the details, but it is {b}keftxoa fì'u nìtxan lu nì'aw[/b] that the head of OPERA resigned. He stated right out front that they believed there was a problem someplace, and that this was not likely new science. This kind of honesty is rare today.

That situation has not been refuted, but neither has the contentious data, they still need to remeasure everything using the OPERA CERN detectors.

At the last reporting from OPERA and ICARUS, as of February this year, the perceived errors in measurement could have added or subtracted time but neither situation was clarified or rectified. To this date, these "measurement errors" have not been identified with empirical clarity, or evidenced to exist in a specifically meaningful way.

Some of the press is hanging on to a fiber optic cabling issue as the cause in the 60 NS delay of light traveling to the cathode. But, they still have not stated explicitly whether a retest occurred using the instruments after the adjustment and fixes cleared the discrepancy, AFAIK.

The only clear refutation in measurement comes from a completely separate bit of instrumentation at the ICARUS detector, and their measurement techniques are not similar. The fact that it agrees with prior notions does not clarify why ICARUS is authoritative over the the OPERA CERN measurements, or if the OPERA CERN measurements will agree with prior notions now that the fiber optics have been fixed. Maybe we are meant to assert this to be the case, but for me this is not clear.

I think this guy is Turkish, so listen carefully.

TEDxSalford - Dr. Umut Kose - Metamorphosis of Neutrinos

Umut Kose is a leading researcher at the OPERA Experiment at CERN. The OPERA Experiment result on "the measurement of the neutrino velocity" has hit the headlines starting from June 2011. In this talk, Umut Kose will give a background talk about the history of  the OPERA Collaboration and their groundbreaking experiment.

Umut Kose was awarded his PhD in 2006 on the analysis of "antineutrino charm production and anticharmed pentaquark search in the CHORUS experiment". Following his Ph.D. he worked as a PostDoc Fellow at Nagoya University, Japan, on the OPERA experiment analysing neutrino events recorded in the Emulsion Cloud Chambers (ECC). He is currently an INFN Fellow at Padova University, Italy, where he continues to search for neutrino oscillations in direct appearance mode in the "nu_mu–>nu_tau channel."
