"Also, its worth noting that monochromatic light does not need two slits in order to exhibit a diffraction pattern."
@juliovega914, don't you mean coherent light instead of monochromatic?


Yes, I do, my bad. Coherent light is by necessity monochrome, but yes.

For those who do not already know, this is a parody of the YouTube channel Pronunciation Book, specifically this video: http://youtu.be/qhTSFdjVf14

I cant wait to never play it because its on a worthless platform.

Other vid is dead. If the other vid the same length as this on? Either way it does seem to be a dupe

In this shameless plug, the mythbustes tested the critical breaking speed of CDs.

The vid features hi-speed video of the breaks, so it supplements this well.

Not too much to listen to (specifically the "percussion" solo) but man is it good to watch

Such fast cameras could be used to determine which slit a photon goes through, no? I mean, in a single frame, not a composite shot, obviously. And used with a photon pump laser, not a photon clump.


The short answer, no. In short, you wouldn't be able to see a single photon, because it can only detect light that strikes the camera itself. the case you see in this clip is a pulse that is very dense with photons, and that are flying everywhere. Consequently, the light you see is not light that is actually going forward, and therefore, not light that is going through the slit.

If you positioned the camera on the other side of the slit, you would see light that has recently passed through the slit, but that wouldn't tell you anything about which slit or slits the photon passed through.

Also, its worth noting that monochromatic light does not need two slits in order to exhibit a diffraction pattern. However tech such as this could definitely be re-purposed similarly to an SEM in order to accept electron emissions rather than photons, which would make some interesting vacuum electron scattering experiments.

I want to go on the record and say that "booty wave" is one of the better mass-market pop songs I have heard recently.

Watched... muted...

*beg Cmon this vid is great!

Um, 2011 isn't over yet and there might be stuff to add to this! We still have 27 days left!


Yeah, think of how much worse it can get!

It's not the sound barrier breaking: the sound is just the sound of the jet going by extremely fast and the shockwave comes from the vapor pressure of jet flying that low over water. Military jets are only allowed to break the sound barrier over specific areas, and definitely not over areas where there are large groups of people.
Still a cool video.

QFT. You wouldn't hear the plane before it passed if it was anywhere NEAR Mach 1.


Actually, I am pretty sure you guys are wrong. That shock collar like that will only happen at transonic speeds.

The sound of the jet you hear as it approaches I suspect is the sound of another jet off camera, or something. FYI, for air shows, they do quite frequently accelerate past the sound barrier.

Edit: fixed wiki link

Done. That's done. That cake is done.

Why are these things not everywhere?
