#9 even more mindblowing: they did an experiment where they blindfolded a person, and touched them simultaneously on the toe and nose. They felt them simultaneously, as we'd expect.

But think about what that means.

The distance from the toe to the brain is so much more, there SHOULD be a detectable lag, given the speed of such signals. So, you think "ok, the brain just delays the nose touch feeling, and we perceive them together."

Except how would it KNOW to delay the first feeling, if it didn't (yet) know the second was coming?

This implies that ALL our perceptions are delayed at least a few milliseconds, and then synchronized by the brain in the right order. Except that nobody's been able to find any trace of a "timestamp" in the simple nerve signals, so how does it sort them properly every time?

My PERSONAL thought is that it doesn't, it occasionally gets the timestamps muddled, and that's deja vous.

Deep thoughts for the day.

@styopa: The human nervous system is one based on electricity passed through your nerves to neurons in your brain, correct? What you're referring to is the drift velocity of electrons through a medium -- in this case your central nervous system. A fast search on the internet returned a result that the transmission of an electrical signal down a wire is close to the speed of light (300 million meters per second)[1], an imperfect, but close enough approximation for some fast math.

A couple quick calculations:
Distance from nose to brain (avg adult) = 5 inches? (.127 m)
Distance from toe to brain (avg adult) = 5 feet 9 inches? (1.75m)

300x10^6 / 1 = .127 / X ; X = .423 nanoseconds of travel time (4.233x10^-10 s)
300x10^6 / 1 = 1.75 / Y ; Y = 5.83 nanoseconds of travel time (5.833x10^-9 s)

Difference in time between Y and X = 5.41 nanoseconds (5.41x10^-9 s)

It's been estimated that "[o]ur consciousness lags 80 milliseconds (80x10^-6 s) behind actual events"[2], so it's safe to say that the response time between the two 'simultaneous' events have a deadband more than 14,000 times larger than your capacity to discern them.

What I wonder is what they used to touch the person's nose & toe at the exact same time. I prefer to imagine they just got some particularly flexible blindfolded folks to put their feet to their face & then thwapped them with rolled up newspapers or something.

#8 - Not true. There are many different languages in the world.

My native tongue has 29 letters. The same 26 as in English, and then 3 additional ones.

"Déjà vu" not "deja vous"
