Headlights That See Through Rain and Snow 210
wisebabo writes "I think it was Newton who said if you knew the position and velocity of every particle in the universe, you could predict the future down to the effect the flutter of a sparrow's wing would have on the weather. Aside from quantum indeterminacy (which, of course, he knew nothing about) and questions of free will, it is clear we are a long long way from getting even close to the theoretical limits of prediction. Still, here's something that, to me, is very impressive. Some researchers manage to track raindrops (or snowflakes) in front of a light and, in real time, change the beam so that they are not illuminated! This drastically reduces glare. The obvious application is for driving cars in inclement weather. I'm hoping we're entering a new age where computers (and cheap sensors) have become so powerful as to make possible a whole host of 'magical' (like Arthur C. Clarke predicted) applications."

"We may regard the present state of the universe as the effect of its past and the cause of its future. An intellect which at any given moment knew all of the forces that animate nature and the mutual positions of the beings that compose it, if this intellect were vast enough to submit the data to analysis, could condense into a single formula the movement of the greatest bodies of the universe and that of the lightest atom; for such an intellect nothing could be uncertain and the future just like the past would be present before its eyes."

Ok, I didn't get the quote exactly right but I think I captured the gist of it.

Yes. I like my statements the way I like my power supplies: Redundant; which is the way I like my statements.

or if determinism necessarily frees us all of ultimate responsibilty.
No, it does not.
