Double Slit Experiment

I was using stumbleupon and I came across this video, and since I know many people are interested in science I though I would share it.

It blew my mind watching it

Kind of an old thing, but I totally get it with the water explanation now.

[SeventhSandwich]

I don't get it.

Does watching an electron make it too scared so that it only goes through one slit?

[fred da kiko]

i got lead off track by the title...

[Packer]

Thats the whole point, no one understands why it behaves in such a way. This is why I enjoy science, just some crazy outrageous things that happen because it can.

Though unfortunately in the video he doesn't say weather the equipment itself was effecting the matter, considering they the matter is getting split into 2 and then reforming as one because of a slit, what would a sensor do to effect this. Gravity and electromagnetism work in mysterious ways.

I was wondering if the equipment would have an effect on the electrons too, but imagine if they were able to react like that or maybe  they have discovered some new sort of force.

I've heard of this, but one thing I never got was wouldn't the detector thing that shows the interference patterns technically count as observing it?

The video representation is a bit misleading. They don't physically observe the electron's position with some sort of camera which is a passive element. Typically some form of high energy electromagnetic wave is fired at an electron and the changes in the fired wave are observed. Unfortunately electrons are kinda small and sensitive so by observing some property of the electron at that moment you drastically reduce the certainty with which other properties can be observed, because you have altered the path of the electron by measuring it.

"Well why don't they invent a new method for measuring electrons!"

If you can think of a way to measure something without observing its physical properties and behavior I'm sure every scientist in the world would like to hear.

No, the detector provides a method of interacting with the electrons, therefore upsetting the potential superpositions. I presume they used some sort of physical counter that relied on the electrons interacting with some part of the detector.
Electrons are a classic quantum particle, being both waves and particles at the same time, or somewhere in between. It's theorised that they travel every possible route at the same time, I'm not terribly educated in how exactly they choose which route but hey, you've got a near-infinite number of possibilities there, all calculated at once. For every electron.

FIRE NEUTRALINOS OR GRAVITONS AT THEM.

INVERSE TACHYON PULSE

[Rainbow]

i saw the title and thought

So an emo double slits his wrist to achieve maximum effect?

FIRE NEUTRALINOS OR GRAVITONS AT THEM.

INVERSE TACHYON PULSE

My bad! Excuse me for not considering these viable possibilities.

[fred da kiko]

super camera....

[IkeTheGeneric]

Magnets

[Skyfrost]

I belive that the reason that said electron split in such a way when being watched, because of the electronic waves eminating from the camera, If you mountead the canon on top of the gun, you might get a different result.

Solely my opinion.
