Please paraphrase the Hiesenberg Uncertainty Principle in 100 ACII characters or less?

Thanks!

DeltaX times DeltaP is greater than or equal to hbar over two.

Our ability to measure pairs of complementary properties is limited to \hbar-sized chunks of uncertainty between them.

There's no point in paraphrasing, there's too much confusion and misconception already.

Sorry, one more try then? ;)

Our ability to predict the next measured value in a pair of complementary properties is limited by \hbar-sized chunks of uncertainty.

My thought on this is that, if you are truly serious in trying to understand things like this, you won't make a request with such ridiculous constraint.

How about:

You can be sure of one property OR another, but not one property AND another.

No. There are many properties for which you can be sure of both; HUP applies when the commutator of the two operators is nonzero.

And on another note, the OP sounds to me like homework.
