    Link: QED: The Strange Properties Of Reflected Light - A description of how, at a quantum level, the reflection of light is governed by probability amplitudes. SCIENCE!

    We all think we know how light reflects from our everyday experiences of looking in mirrors and other reflective surfaces. This video demonstrates that, at a quantum level, those everyday phenomena we think we understand in fact have a deeper cause related to the dual wave/particle nature of light.

    This video is intended for laymen. If you`re interested in hearing about the same phenomena in more depth from a real master of the subject, this lecture by Richard Feynman explores the concept of Probability Amplitudes in more detail.

    The light reflecting off the ends of the long mirror did not bounce off at the same angle as they hit.

    So the real question here is, who spent millions of R&D dollars to figure out that you can affect reflections in glass based on the thickness of the glass?

    This is really enjoyable stuff, but I do appreciate your second link much more MacGuffin. This guy`s voice was a little annoying and I find Feynman much more bearable.

    It show us how little we know about our reality. We dont even fully understand the properties of light itself

    OK OK, I get all that. I have only one question: What practical purpose is there to knowing magnetic moment to 16 significant digits?

    Was actually looking forward to this video. Couldn`t get past how annoying this guy`s voice was.

    I didn`t watch the whole thing. But does this say anything about the phenomenon of having your kitchen lights on and not being able to see out (while maintaining a stronger reflection), vs. turning them off and being able to see out without others looking in so well? It seems obvious, but it`s a window isn`t it? Why should it work differently when the sun`s out and you can see either way just as easily?

    @Draculya - You`ll almost defiantly never see this. The probability is nearly 0...scientists could probably measure it to 0.0000000000000000001321%.

    Maybe the best reason to measure and estimate to such a high degree is not for practical application. More likely is for proof of concept. Newtonian physics can be seen and demonstrated. Like...if you drop a ball, you can SEE and measure how fast it drops. Quantum physics cannot be viewed because, simply viewing a particle changes what it is doing, where it is, and where it`s going. By measuring an testing to such a high degree, it shows that the current theorys on how things work is correct!
