> [@Chronos](#): > > Question _too_ far, and you end up just wondering whether you might be a brain in a jar. is this a natural sentence you just wrote, or an aphorism (well) known to Descartes students? In fact, I only thought of Descartes _after_ thinking that the sentence referred to the Saga of Einstein’s Brain. Anyway, i have taken the liberty of re-lineing it for clarity, iambic pentameter, and to clean up a slight hiccup in prosody: Question that _too_ far, And you may end wond’ring If your brain’s in a jar. ---

The OPERA collaboration has put out an official statement, quoted [in this article](http://www.nature.com/news/flaws-found-in-faster-than-light-neutrino-measurement-1.10099). > [@OPERA](#): > > The OPERA Collaboration, by continuing its campaign of verifications on the neutrino velocity measurement, has identified two issues that could significantly affect the reported result. The first one is linked to the oscillator used to produce the events time-stamps in between the GPS synchronizations. The second point is related to the connection of the optical fiber bringing the external GPS signal to the OPERA master clock. > > These two issues can modify the neutrino time of flight in opposite directions. While continuing our investigations, in order to unambiguously quantify the effect on the observed result, the Collaboration is looking forward to performing a new measurement of the neutrino velocity as soon as a new bunched beam will be available in 2012. An extensive report on the above mentioned verifications and results will be shortly made available to the scientific committees and agencies. ---

It’s the general sort of thing that Descartes pondered about, but I don’t think he ever used the specific brain-in-a-jar example (his equivalent was an evil illusionist demon). ---

Heh, one of our elder professors came into my office Thursday morning all excited to spread the news of the possible experimental errors; apparently, he’d just read about it and was now making the rounds to tell everybody. Somehow, this struck me as really – well, _cute_ is not really a word I’d associate with him, but it was certainly nice to share his excitement… ---

\*European researchers said Friday they had measured again the speed of a subatomic particle that a September experiment suggested traveled faster than the speed of light, violating Einstein’s special theory of relativity, which underlies much of modern physics. The research team, led by the Nobel Prize-winning physicist Carlo Rubbia, found that the particles, neutrinos, do not travel faster than light.\* [NYtimes](http://www.nytimes.com/2012/03/17/science/einstein-proved-right-in-retest-of-neutrinos-speed.html) Link.
