neutrinos and graphene

So I just wanted to post something that I thought was very interesting.  As a physicist I have seen a lot and gotten a lot of questions about neutrino's traveling faster than the speed of light.  Though I have not read the paper my response as a theoretical physicist was about the same as when I read an experimental paper in my own field that is exciting:  Hey - that would be cool (in this case ground breaking) if it pans out, and then I proceed to wait for the next paper (or three) to confirm it one way or another.  Because one of the key things that little Scientists (cough- undergrads/gradstudent) learn as they grow up is that science is a process of discovery, check, re-check, confirmation, and validation.  So if a single paper stands out it must be proven by others before we are confident in it. 

This is the case of the recent Nobel prize winners who discovered graphene using scotch tape.  Everyone was amazed (for nearly 60 years graphene had been proposed to possibly exist (and be heavily studied experimentally) but no-one could create it or any other purely 2-D materials), but they didn't win the Nobel prize until graphene could be recreated by other groups with the same and other methods.  And now graphene is one of the most exciting materials that people can study.  Going further on a tangent - I just want to say to those who say Andre Geim and Konstantin Novoselov and got their Nobel Prize early, that graphene only has potential but hasn't been proven to be as important as everything thinks it will be:  They proved  2-D structures can exist after 60 years of debate about the subject USING SCOTCH TAPE!!!!

But anyways getting back to the neutrinos going faster than light.  Some theory (some versions of string theory leave the possibility open) and experiment already exist (according to the blog I am going to link to below) but they are a little contradictory and also the experiment was for a different "flavour" of neutrino.  So this is all a big build up to link to a friends blog who read the paper and gave a nice analysis of why Scientists look for confirmation from other sources before they believe new break discoveries.  So I suggest that you go look at Miss Atomic Bomb's post.

    And you're absolutely correct. The results have the potential to be very big news... but not until we're sure they're right (and we do that by checking them in a systematic way).
