Nerd Warning – I you don’t care about quantum mechanics and encryption then you probably don’t want to waste your time on this.  Otherwise, this article is freaking awesome!  I’ve only included some excerpts so follow the link for the entire article. Enjoy!

Quantum entanglement is weird. And I mean weird even for quantum mechanics, which sets a whole new level for weird.

Why is Dick York’s picture here?
Is it entangled with this post? Spooky.

In the world we live in, the macroscopic world, if you flip a coin, it can either land heads or tails (ignore it landing on its side, the results of which have been thoroughly discussed in The Twilight Zone). That’s it. But in the quantum world, that coin could be both heads and tails, with an equal probability of both. Until you actually examine the coin and see which way it landed, it exists in that weird in-between state.

I’m not making this stuff up. This is very real, as real as atomic bombs, computer chips, and solar cells. In fact, all three of those depend on quantum effects, so we know, which absolute certainty, that quantum mechanics works.
