Yeah exactly. I just think it is interesting that even though electric
signals can travel ridiculously fast, one is stuck with one's personal
electrons for quite some time until they bid farewell. Jens

the slack in all of the couplers going in, and that wave travels
the length of the train at around 30 mph, even though the train
is nearly motionless.
The secret to it seems to be that each electron does not have to
travel very far until "bumping" its neighbor.

Yeah, it probably is wrong. That was why I said it WAS 50 years ago.
Maybe I
misremembered the figure too. They did describe the experiment that
provided
the figure but I have zero recollection of that for some reason.
Maybe I misremembered more too. Interesting that the 3 inches per
hour
would be close to 2.7 inches per hour. I still have a lot of the old
school
books - I can picture the book involved as a softcover A4 on its edge
variety. One that was written by a group of physics teachers
specifically
for the curriculum; very easy for there to be errors in it - they got
Static
and Dynamic tube/valve curves confused.
Point is though, 'electrons' travel slowly, the effect travels
quickly. Yes?

27ft/s seems high, see here:

Many years ago [50] in school physics we were told 27 feet per

one
falls out at the other.

What I find particulary amusing is that the drift velocity of the
actual
electrons is of the order of a cm/s if I remember correctly. Jens

Yes, that is correct! Because electricity travels
through a wire at the approximate speed of 1 nanosecond per
foot!

may have gotten a little bit bigger but not by much but could

imagine the size of a computer based on the ENIAC

modern day version would need its own power station and would
take

Ah but you are forgetting as Admiral Hopper liked to point out,
the
size
of a nanosecond. A football stadium sized computer could not
get out
of
it's own way.
