uncertainty, in principle

If you're even a little familiar with quantum physics and chemistry, you've probably heard of the Heisenberg Uncertainty Principle.

Basically, it goes something like this: there are certain pairs of variables that cannot be precisely measured at the same time. Sounds a little weird, I know. The classic example is position and momentum - so what we're saying is that if you know precisely where something is at (it's position), you cannot precisely measure its momentum simultaneously. And vice versa. The uncertainty principle effectively says there are some physical things that, under certain circumstances (and here, on a quantum level), science can't measure.

It follows that there is no way to completely, 100% describe the state of the universe at a specific instant via scientific measurement.

Interesting thought, isn't it? The implications there are worth pondering - and I'd love to ponder a little more here this evening, but I'm not going to lie - it's been a long day, and I think it's time to get some rest.

So I'll leave you to ponder, and revisit this another time.

That's my quick hit for Monday night. :-)

+peace, and all good.
