    How can you tell the difference between a raw and boiled egg?

    Actually I knew about this, raw eggs are MUCH harder to keep spinning at a high rate.

    Undergrad Possible to modify a magnet to be more beamlike

    Not that I know of. Magnetic field loops need to have a path from the south to the north pole, although if the field loops were mind-numbingly huge it might seem to act like you want...

    Graduate Calculating focal length for aspherical lenses

    How is it done? I've done a little research on Wikipedia and found the lensmaker's equation, but one of the values needed to compute focal length is the radius of the lens curvature. Strictly speaking, an aspherical curvature wouldn't have a set radius, would it? The reason I'm asking is because...

    Didn't receive Confirmation E-mail

    Hello, I had this exact problem trying to register. Fortunately I have a 2nd e-mail address and that one worked. The user name I was trying to register is the same as my current one but it had a space (i.e. Captain Barbosa.) My ISP is Wideopenwest.
