When I see a reflection in a mirror, is there any lag between me waving my hand and it appearing in the mirror? Something like .000000000000000000000001 maybe?
So there you have it. The serious question got a serious answer. There is indeed an imperceptible lag at the typical mirror-viewing distance.
Now lets get some not-so-serious ones.
Why myopia (short-sightedness) is not fixed when looking into a mirror while the mirror is placed at a short distance from your eyes?We need to go deeper...
Better question: Does the wind have a pattern? If so, how does one follow it?
I would have thought the wind would be a good example of Brownian motion.
