I already knew that aspect, I just misread the article - it was a PHOTON scattering off of the atom (not an electron, which is what I thought they originally meant - that they were taking a picture of the scattered electron by watching the oscillation)Originally posted by: silverpig
They're taking a video of the quantum state of an electron in a helium atom. Sure different electrons are invovled, but because they're identical, and come from the same state, it's fine to say this.Originally posted by: Eeezee
But then that's not really a movie of an electron at all, but rather a video of a change in detection position. This is a fine experimental method, but I think the title of the video is a bit misleading.Originally posted by: silverpig
From what I get from the story they are showing the point at which an electron leaves an atom can be changed by changing the timing between laser pulses. What you are looking at is an image of recorded positions of electrons hitting a detector. When the images shifts, that's indicating the point at which the electron leaves the atom is shifting.Originally posted by: Fenixgoon
so if i interpreted the news article correctly.. that movie is showing the change in energy distribution of a single electron (or is it an atom?) as it is hit by light.
This would be like claiming that a video of a person's footprint in the sand is a video of the person (obviously a person was there, but you've just taped the consequence, not the actual person)
A better analogy would be to say I made a movie of you walking to work by taking one picture of you a day. The first one is of you leaving your front door, then the next day I take a picture a second after you leave your front door. The next day I take a picture of you 2 seconds after leaving your door etc, then build them up into a movie. You're the same person every day, and electrons don't wear clothes, so by doing this I could make a movie of you walking to work.
