Tani's question was about the double-slit experiment. The top two pictures are of an unobserved experiment, in which an interference pattern is formed; the bottom pictures have an observer watching each slit, and the resulting pattern is bimodal.

Lego ninjas make excellent observers.

If a double-slit experiment occurs in the forest and no one is there to see it, does it make a sound?

or...

If there is no one there to observe it, does it even occur?

Ah. I would never have guessed that... if I ever heard of that experiment, it was a long time ago.

Ah... yes

I recently watched a 60 minute demonstration of this, on one of the National Geographic Channels!

However, the "romantic" side of me was expecting a puzzle of some type... such as, if two Samurai stood on opposing pedestals, what would be the least number of jumps, not leaving the current level in heights, for them to exchange positions. :o)
