the best video of physics i have ever seen
i want this in all other chapters too..
please give the link to other topics also?

@stevebenbob We never discussed or even defined "conscious observer" in our QM or Quantum Field theory classes. When fields interact, they do so at a point in space-time, and this collapses the wave function. The Universe actualizes itself in this sense, whether any 'consciousness' has evolved in it or not.
Could you tell me where the need for consciousness is discussed in a physics text? I know it is a common theme in non-rigorous discussions, but I don't see why..

wow

man, this video bugs me because you can interpret it any way you like. Did you know the guy this cartoon is based on does his lectures with religious connotations. He carries a cross around with him in the background but speaks of science. You make the connection, and dont forget to donate to the church

they say the same thing happens with bucky ball atoms (the largest atom known) so how about molecules. How about clump of molecules. At some point the clump of particles no longer acts as a wave, maybe at the point we can see it, because I know if you shoot two marbles through it will surely form two lines. Bottom line is, if we cant see it who cares what they do. They could circle the planet, but reform in my field of view when I expect to see it there, so I can predict my environment.

Great video. Clear, illustrative, entertaining. What a lot of work it must have been. Thank you! Comments here: some excellent, some dumb (take a course in physics instead of just trying to guess). The spelling in the credits was, with out doubt, horrible. Realy.

Electrons like Photons only seem to exist as a wave until they come in contact with an object. Then the wave function collapses forming a quantized form of energy. If this is a universal and continuous process could it be forming the passage of time? Because each new Electron or Photon will have a unique position in space and time that the wave function never had before the collapse. Could Heisenberg Uncertainty Principle be the same uncertainty that the observer will have with any future event?
So electrons interfere with themselves? Dirty little bastards.

I've taken courses in QM and QField Theory. This is one of the clearest explainations I've seen. It's all correct. The only thing you may quibble, and I usually do when I hear it, is that 'observation' does not have to be a concious observer -any physical 'disturbance' or 'interaction' will collapse the wave to a point interaction - and this is always going on in the universe.
