it's the double slit experiment in the video. the question i have is, what is the thing that's in super position. the video presents it like
there's a sheet of metal with a slit in it. in front of the sheet of metal is something like a chalkboard. a device that fires marbles, shoots
marbles thru the slit, where it presents itself as a single row of marbles on the board, directly in front of the slit.
then a new sheet of metal with two slits is used, and the marbles are shot at it, and it creates two rows of marbles on the board in front of it.
then a wave of water is propagated at the metal sheet with one slit, and it presents itself as a single bright band highlighted the brightest where
the peak of the wave hits the board in front of the slit, similar to the single row of marbles on the board.
then the two slit metal sheet is used, and the wave of water enters the two slits, comes out the other side of the metal sheet slits, the waves
interfer with each other, creating an interference pattern on the board in front of the slits.
the interference pattern is represented as several bands on the board, equivalent in appearance to the board being hit by marbles thru several slits.
but without the need for several slits
then electrons are fired at the single slit, which creates a single band on the board in front of the slit.
then the two slit board is used and electrons are fired at it, and it creates an interference pattern. since it's supposed to be a particle, and is
acting like a wave, they try to figure out why it's doing that.
they put a measuring device by one of the slits, to see which slit it is going thru. but observing the electron causes it to go back to acting like a
particle instead of a wave. the act of observation, they conclude, has collapsed the wave function.
the math indicates that the particle is going thru both slits, and one slit. thru the left slit and the right slit. and no slit at all. this they
called super position, stating that the particle before it's observed is existing in all possible states of being at once. only observation changes
that. observing it, essentially, materializes it into matter.
but it only acts like that, when it's given more than one slit to go thru. if the slit is single, it continues to act like a particle (bit of
