I'm new, and theres a video i don't quite understand, whether it is true or not. I just need to know what it means lol
Here it is http://www.youtube.com/watch?v=o8CwBKkKpvs
Not sure if this is the right place either.
Full Version: Can someone help me?

Sorry, can't help you....I failed science class...... 
The bit that baffles me is "they act differently when being watched" Is this true? Or am i thinking of something totally different? Is it possible?
Quantum eh? Not my specialty but, seems to me the wave pattern of the electrons has to be established before the slits, placing an object (the observer) in that area disrupts the wave pattern, so now you get the marble effect. Just a thought.
Quantum weirdness is...well...weird.
Saying 'they act differently when being watched' isn't entirely accurate. It would be better to say that observation of quantum phenomena invariably alters (because the particles are so tiny and the methods you have to use to observe them require a lot of energy) what you are trying to watch. It just sounds a bit spookier (and less geeky
) to say it in the way they have.
The wave-particle duality bit is weird and physics is still trying to explain how that can happen (there are several theories about it). The bit about how a particle can be in two places at once (superposition) is also poorly understood.
All in all, it explains something of what we know about quantum theory, while at the same time being inaccurate enough to give people the wrong impression of what we know of it.

Well, Leonardo, maybe I became a bit confused as to where they placed the "eye on a stick", but if it was placed near the electrons, then wouldn't it possibly just be interfering with the wave pattern, causing it to revert back to the dual lines instead of the many lines? (Sorry for my ignorance in this area.)
You got it. The observation of the electrons did interfere and this is why the number of lines changed. I don't mean the 'eye on a stick' was in the way of the electrons in the sense of blocking them, but the energy it used to see the electrons is also a wave and this interferes with the electron wave. You get a different interference pattern as a result.
What I was implying though, is that the electrons themselves don't 'change their behaviour' or 'act differently'. They have no behaviour to change (as far as we know). We are simply interfering in the experiment.

Which makes absolute sense my dear. And I would like to thank you for cramming a bit of science into my paranormal history filled brain LOL!
Hey airika, I dont know if this stuff really interests you or not, but there's a pretty good book out there that's like Quantum Mechanics for dummies and philosophers. It's called the Dancing Wu Li Masters. Even someone with no background in physics/ Newtonian mechanics can get the basic jist of Quantum Mechanics from the book. I always thought it was a fun reading.
