    Graduate Will the fusion reactor ITER decrease entropy?

    ITER is the fusion reactor in southern France that hopefully will come online in 2018. According to wiki http://en.wikipedia.org/wiki/ITER The ITER fusion reactor itself has been designed to produce 500 megawatts of output power for 50 megawatts of input power. Does this mean that if...

    Graduate What is the energy-time uncertainty relationship in quantum mechanics?

    This is from Hogdson's book the Mind Matters Does anyone know what the actual equation he is talking about and I was wondering if anyone could give me a few more details regarding the energy-time uncertainly relationship.

    Graduate Why quantum effects disappear at the classical level

    But the duck's answer looks so obvious and easy to understand. I guess liquid helium and bucking balls are anamolies, right?

    Graduate Why quantum effects disappear at the classical level

    Thanks for that info, I didn't know that. Does decoherence require the many world interpretation?

    Graduate Why quantum effects disappear at the classical level

    I forget where I read it but one author said that mountains of ink have been spilled debating why quantum effects disappear at the quantum level. I don't understand why this is a problem, I think the answer is rather obvious. One poster on another thread wrote: "Technically - classical physics...

    Undergrad You can't do operations on infinity

    ok, looks like I didn't know what I was talking about. Thanks for clearing things up.

    Undergrad You can't do operations on infinity

    I'm trying to get my words right. They say you can't do operations on infinity. Sorry I don't have an exact quote. But on the other hand you can do calculations involving infinite series. What is the proper way to describe what math can't do with infinity? I want to say something along...

    Graduate Should the speed of light be slightly uncertain?

    Thanks. I appreciate your help.

    Graduate Should the speed of light be slightly uncertain?

    I read it before you advised me to read it of course and I still don't understand what you're getting at. If what you're getting at is the speed of light is relative to the observer, well, I already know that but I still don't see why it's speed cannot be uncertain.

    Graduate Should the speed of light be slightly uncertain?

    Don't know what you mean by integer. Also didn't understand why you wanted me to read the wiki article on meter.

    Graduate Should the speed of light be slightly uncertain?

    The position and momentum of a photon is uncertain. If that is the case, then shouldn't the speed of light be slight uncertain?

    Graduate Understanding the Copenhagen Interpretation

    This is some other guys interpretation whom I don't really trust. So if you find anything wrong with it I would appreciate it

    Graduate Understanding the Copenhagen Interpretation

    What about in the double-slit experiment and a detector is placed over the two slits? I think a particle is sent down from the detector which records which slit the particle went through. Isn't that a sort of measurement? Thanks for your help.

    Graduate Understanding the Copenhagen Interpretation

    This is from Wikipedia regarding the first point of the Copenhagen Interpretation: What does it mean to make a measurement? Is this something that only living beings do or can a dead particle make a measurement? Why does measurement collapse the wave function.
