Yeah, that's what makes semantics so much fun! And is the cause of so many conflicts Frown | :(

There's a really cool illusion that I like to show people when I take them on a walk at High Falls[^]. I tell them to stare for 10 or 15 seconds at the waterfall and then shift their eyes to the adjacent rock face. The rocks appear to move upwards. You can get the same affect, say, biking. Staring at the road moving toward you, and then look up at the sky (a few clouds are necessary) and the clouds look like they're receding.

It's amazing how bizarre the sensory system and the brain perceives things consciously. I finally realized that in order for me to perceive an apparent motion when none exists, that the brain is actually handling motion and shape as two completely different processes, and the imbalance caused by the over-excitation of neurons in one direction of motion results in the illusion in the opposite direction, even though the physical shape isn't changing. Re-integrate the two in the process of conscious perception, and you get the illusion that the damn rocks are moving.

Sorry, probably TMI, but it really is amazing, and the reaction people have when I show them the illusion is always amusing.

Straw Poll

Were you affected by the geomagnetic storms this past weekend?
Communication disruptions, electrified pipes, random unexplained blue-screens in Windows - the list of effects is terrifying.
