The point of the matrix thought experiment was to show that motion is a just sequence of photographs. Wasn’t really about the number of raindrops That’s why I linked to the earlier post that is ostentatiously about Philip K Dick. If you haven’t seen the water and sound video already, I highly recommend it.

The best angle for a windshield or any surface to be hit by the fewest number of anything falling perpendicular to it is obviously 90 degrees. Under ideal conditions. The best statistical bet is 45 degrees since there is no way to predict wind directions. So that sounds more like a statistical problem than about counting the number of raindrops. Like most mathematical problems.

The raincloud density will vary because of the wind, but assuming it doesn’t. if the windshield moves by a distance of dx, the change in dy would be the shift in raindrop pattern.

Only way to graph it out is to have a working holographic video imaging device that can record everything inside a given space, and then reduce the space to a number of cubes and track the change of number of raindrops inside each cube over an extended time. And see if a pattern emerges. Everything in nature is fractal so the raindrop patterns are bound to be regular as well.

I don’t think the windshield angle would make a difference, unless of course it has to do with the stress/strain ration of the material that suspends it.

Just the fact that he was given the assignment makes me think it does matter how fast you’re going, but I don’t remember what he concluded. ]]>
