This confusion over particle versus wave properties was eventually resolved with the advent and establishment of quantum mechanics in the first half of the 20th century, which ultimately explained wave-particle duality. It provided a single unified theoretical framework for understanding that all matter can behave in both a wave-like and a particle-like fashion in the appropriate circumstances. Quantum mechanics holds that every particle in nature, be it a photon, electron or atom, is described by a solution to a differential equation, most typically, the Schroedinger equation.
My theory is an abstract version of all theories I've heard, but its pretty standard. Everything occupying the universe exists as a wave in time. This is true because time is a function of the travel of a wave (light) and is relative to the speed of said wave. Taking in account of this slit experiment with electrons (I only heard of the one with light), it further confirms my suspicion that all matter exist as waves interfering with eachother and producing the phenomonae we see as the 4 forces in the universe. Thank you very much, you gave me one more elementary step towards the unified field theory.
Coherent presentation, but lacks understanding of the basic principles behind the phenomenon. Electrons of course interfere with each other; they are negative particles and as such, repel causing the striations. Lasers can be streams of particles, but, typical red lasers are streams of quantitized light (photons or quanta), the basic principle behind quantum mechanics (Photons are ‘packets’ of light).
You may be confused with cathode ray streams (which are actually electrons). I think this is simply a rehash of a presentation you have viewed online as it shows lack of knowledge of basic physics. I think however that you are educating the uninformed in the wonders of scientific advances is to be applauded.
Anyone who knows that the Bohr model was proved wrong (you know, the one that they still use...) should know that electrons are not particles like marbles, but rather travel in waves. I liked how you explained how it was discovered, cool stuff indeed. People need to stop referring to the string theory as "new" =/
I'm a physicist. You made some mistakes. If you shine light on a single slit, you DO see a diffraction pattern, not a vertical line. Also, white light doesn't work (as you vaguely implied) because the component spectrum will diffract different amounts. The electrons do not "interfere with each other"-- you corrected yourself, but that phrase shouldn't even show up in your explanation. Finally, saying that the electrons "go through both slits at once" is a bit misleading. I love spreading physics to the masses (no pun intended), but I don't think YTMND is the medium for it.
