Isnt dis d phasor method??? nd he can appply it as ell, coz evrythng is a wave, nd waves can be expressen in phasors(Harmonic)

@abe3775 That's it exactly. it involves adding up probability amplitudes just as you would add up phasor amplitudes

[abe3775]

@MuonRay but how did he prove that probability amplitudes are harmonic?? coz acc. to my knowledge, dey need to be harmonic inorder to add them

WOW! When he did the lens thing my mind was probably more blown than it has ever been! I have to watch that again.
