  1. Re:Question... on Physicists Plan to Build a Bigger LHC · · Score: 1

    \gamma = E/m

    E = 50 TeV, m = 938 MeV

    v (in units of c) = \sqrt(\gamma^2 - 1)/\gamma

    Or in other words, far more 9s than a double will hold. The rest is left as an exercise to the reader :)

    Actually that does happen. If the torero believes that the bull is exceptional and performed extremely well then he can pardon it. Then the bull goes off and makes bull babies for the rest of his life.

    2. IREX DR800SG - You can port over any program you can imagine to it if you are so inclined, it has an awesome screen, and its PDF capabilities are pretty good too (getting better with new revisions of firmware).

    Curiously though it is no longer on Best Buy... no clue why.

  4. Re:Why is this still in the news? on Google Relents, Will Hand Over European Wi-Fi Data · · Score: 2, Interesting

    Google has stated that their equipment changed channels 5 times a second. So there is no more than 0.2s of data on any one network. Good luck doing anything with that...

    Yeah... except for in TFA they say that the camouflage WAS a case...

    Close, but the gravitational mass is still the same as the inertial mass in GR. The hammer and the feather still land at the same.

    No and no.

  10. Re:*coff* on Austria To Pull Out of CERN · · Score: 3, Insightful

    Thing is the point of the LHC isn't really to find the Higgs boson (the God particle name really is oversensationalized). For most physicists the existence of the Higgs boson is a foregone conclusion. When they see the experimental proof it will be little more than a hmm, well looky there, what we knew all along is true.

    The true purpose of the LHC is to uncover the unknown by probing energy ranges that have never been seen before. The LHC will payoff when they find a result that they have no idea how to explain which will push for new physics.

    All of these things may or may not have a direct practical application. When they started building accelerators they had no clue that it would later be used for cancer treatments. Does that mean that just because practical benefit is not immediately obvious that pushing the boundaries of experimentation is a waste of money?

    I think not.

    Disclaimer: IAAP (in training, no Ph.D. yet) and have studied with a professor that is directly involved in the LHC.

    > Can anyone name a single discovery in HEP in the last 25 years that has led to a practical improvement of anything whatsoever? The only thing HEP has generated is paper.

    That's an easy one: The particle accelerators developed for research in HEP have directly resulted in the accelerators used in hospitals for radiation therapy.

  15. Re:Citation needed on Quantum Test Found For Mathematical Undecidability · · Score: 1

    This is mathematics goes far, far beyond just counting. I'll give you that originally math was invented to serve a real life purpose. The more important and surprising mathematical implications over physics have come from abstract mathematical work that was done without trying to explain anything around them. Citation: http://en.wikipedia.org/wiki/Group_theory#History Group theory has some extremely far reaching implications over physics in the fields of quantum mechanics, general relativity, particle physics, etc.

  16. Re:Actually on Quantum Test Found For Mathematical Undecidability · · Score: 1

    How does it have anything to do with Heisenberg's uncertainty principle? That relation is a direct result of the properties of Fourier transforms. The randomness in quantum mechanics being described here is the inability to know to which of the eigenstates the wave function will collapse to after being measured beyond the probability of obtaining each state.

  17. Re:It is still overblown on Quantum Test Found For Mathematical Undecidability · · Score: 2, Insightful

    Mathematics is not, in general, refined to describe reality. Mathematics is refined by taking every logical rule to its farthest reaching implication. This goes far, far beyond anything that we currently see as based in our reality (though, as the current argument is about, it has the uncanny tendency to end up describing our physical reality extremely often). Physics however IS refined to describe our reality. It is precisely physics that ties the mathematical underpinnings to the reality that we observe.
