    Welcome, Mr. Berger. Fancypants title you got there.

    Why did Copernicus cross the road?
    He didn't have to, he was already there.

    My housemate works in the lasers lab and I've discussed using laser interferometry to precisely measure how thick an edge is - we haven't worked up a scheme yet but the thought is there. I'd like to get the setup such that someone could build it with some machining knowledge and a laser pointer but don't hold your breath for schematics for a while!

    Thanks for all the welcomes guys

    What PhD student has enough money for a workshop? One where he can make kitchen knives no less.

    Welcome aboard!

    Ok, Apprentice Physicist, what's up with the speed of light being surpassed?

    Things like this happen occasionally but noone nessisarily takes it seriously. For about twenty years when they measured the mass of these objects (the particles in question are called neutrinos) they found that the (mass^2) value was negative. The error bars made it reasonable to say it is basically zero and that is what was reported by if you look at it they basically had negative mass^2. This is obviously ridiculous as mass has to be a positive value. Eventually they found that there were some errors with the detectors and the models and now the mass is positive and that is generally accepted as true.

    It is quite possible that this is a similar thing, they haven't openly said they believe to have found something which surpasses the speed of light. They have been careful to say they have measured it and are asking the rest of the world to scrutinize the result for where the discrepancy lies. Safe money is definitely on the speed of light still being the fastest you can go as there is an overwhelming amount of evidence that says this is true from the last 90 years of physics. Crazy money is of course on the fact that a 6.1 sigma result is massive and if this is real then everything in the last century has been fundamentally flawed and all the textbooks get to be rewritten.

    Noone in the scientific community yet believes that we have found a way to break the speed of light though - but it does make a good headline.

    That a good explanation? (btw gogol is awesome, nice avatar)

    Jeff,
    Welcome. I don't know if we were introduced, but I did the mokume lecture and demo at last years ashokan. Did you make it this year?
    If you want someone to bounce ideas off of as far as the kitchen knives go, well I have learned a lot in the last year, and I would be happy to talk shop with you.
    I love physics too, I just didn't get enough math in for the heavy stuff.
    Thanks,
