    More more more!!!

    Terrific video! Until now I had thought that I had a pretty good handle on
    the tunneling phenomenon but, alas, I had it just a little backwards.( I’m
    the first to ever misunderstand quantum phenomenon )
    Thank you to The Tabletop Explainer et al. for this and similar videos that
    bring understanding of the world in which we all live a little closer.

    why wasnt heisenberg mentioned?

    Does a force acting on the proton, say, it bouncing off a certain barrier
    act on the proton itself or its cloud of probability as a whole
    If it acted on the proton then wouldnt we know exactly where it is based on
    when the cloud bounces back (.say, when the middle or the front reaches the
    barrier.) thus nullifying the probability cloud

    This isn’t enough. It doesn’t tell me what it is and how it works. All I
    learned in this video, is that quantum tunneling is some kind of magic that
    overcomes the repulsion of protons. What is it exactly? How does it work?
    Why does it work? How do you know? Does it only happen in atomic fusion? If
    racket balls have a tiny chance to “tunnel”, why don’t they ever?

    Great.

    Terrible presentation. Does not explain what quantum tunneling is or what
    it has to do with the sun shining.

    so did i get it ryt. quantum tunneling is all about breaking the barrier
    between the particles to fuse them or did i not. !!!!!!

    I don’t get why we haven’t invented magnetic cars or magnetic accelerators.
    Magnets are amazing

    well worth my 200th favourite on youtube

    Freaking cool

    I don’t understand when he says light atomic nuclei…since when does light
    have a nucleus?

    Russian Rubles must have been moved to the Hammer Fund of Cantor Fitzgerald
    Fund and the reason why Snowden was snooping around to focus our attention
    on the NSA, which would make the CIA focus their attention on a scapegoat
    in Benghazi and thus the fractal stock market (hidden)

    Quantum physics is based on the wave-particle duality, which states that
    all particles have wavelike properties. This means a classical particle
    (for example an electron or a photon) can exhibit either particle like or
    wave like properties. Specifically, before a classical particle is
    measured, its position can ONLY be described as a probability
    wave/function, in which every space in which it may be has an associated
    probability.

    I just… bluh, it weirds me out, I can’t explain it. In my defence, I read
    A Brief History Of Time and found it interesting 😛

    Shoud I say it? You have 0 dislikes, “wizard”

  18. SonorousTwo8 April, 2013 at 1:19 pm

    I guess so.

    Clasic Physics: Ah shit I have to go over the hill to get to the other
    side. Quantum Physics: Fuck you. *tunnel* *tunnel* *tunnel* (Otherside of
    hill)

    Wrong, the sun creates light through fusion. through NUCLEAR FUSION.

  21. feynmanmagnets25 May, 2012 at 10:29 pm

    We actually observe clusters of particles tunneling pretty regularly.
    Besides, aren’t protons and neutrons also composite particles? They’re made
    of quarks.

    And here I thought that fotons/Electromagnetic (EM) radiation are just
    emission caused by moving/vibrating atoms that happens as in the stars as
    in the any heated (vibrating) matter. Material can be heated by the
    electric current like the sun can be heated by the birkeland current.. I
    wanted to say, when particles in the sun are fusing (do they even need to
    fuse?) together because of tunneling and make emissions, why aren’t any
    other particles funing too? Like our bodies, Earth, water we drink?

    @shaygahweh The thing is that YOU can do it.

  24. Ryan Mcleavy3 December, 2011 at 10:24 pm

    @alotoaltosaxes Watch the Sixty Symbols video on Quantum Tunneling They
    talk about touchscreens! 🙂

    @SuperFinGuy its appalling what passes for education these days. Attempting
    to sound smart (when you obviously have no idea what you’re talking about)
    makes you sound like an idiot. Get an education; and while you’re at it,
    learn grammar.
