If you're from the US or Canada, there's an amazing video series that you can watch online called The Mechanical Universe:

You have to register an account to watch, but it's free. It was put together by CalTech, so you know it's much better than some random link you'll find on YouTube.

are you against books?

i reccomend brian greene for reading

thanks to all
will try to check everything out

should really refer to it as "young's double slit experiment" give credit where credit is due.

how can it act differently just by u observing it, but still produce the same shit i dont understand

It doesn't produce the same thing. That's the point. Rewatch from ~4:08 to the end.

when you look at it, you're bouncing photons off of it (photons are light "particles") so there's a phenomenon known as "wavefunction collapse" (google it, im not making this up)

nobody understands it (in a philisophic sense), but the math behind it and everything else perfectly describes matter on small scales

Interesting read while we're on the topic of quantum physics.
