I'm presently serving on the Phoenix Library Bond Subcommittee.
Three new libraries are going into the poorest sections of town, and
all will be accessible by mass transit as well.

Such a terrible waste of money to grind up trees, sprinkle them with
pigment, then ship them around the globe. Much better to spend the
political energy making sure that books can be made available online
and then spend the money on making sure everyone has Internet access.
This business of requiring *children* to lug many pounds of weight onBob said:There is a $100/laptop thing going on (http://laptop.media.mit.edu/)
My kids both carry about 40 lbs of books to school in their backpacks. The
teachers rarely if ever refer to them, but require them to be brought in,
just in case.
A 'dynabook' (http://www.artmuseum.net/w2vr/timeline/Kay.html) would sure
be nice. Weighs a pound. Upload any assignments via classroom wireless.
Schools could buy contracts for some number of downloadings of textbooks,
and students wouldn't have to use science textbooks written in 1983 (I'm
not making this up). Students could turn in assignments by wireless or
email, and surf the web if their teacher is boring or stupid.
Why not? All the technology is there, and $100 less than the cost of most
college textbooks.

When i grew up and had a fair number of books for school, there were *lockers* in the school for them and we were given the
combination.
After one class let out, we would go to our locker and place the one or two books from that class, and remove the one or two for
the next class.
There may be one or two classes that requierd homework on a given night, so two or three books would be taken home.

Absolutely.
That being said, for a kid born today having (free) Internet access probably
is about as important as free book access was to a kid some 30 years ago;
among people who already have a grasp of the subject.
Fascinating talk tonight by Gordon Moore of Intel, at the Computer History
Museum in Mountain View, Carver Mead acting as interviewer. (For those who
don't know them, Moore was a co-founder of Fairchild Semiconductor and later
Intel, and a seminal figure in that industry; Carver Mead a professor in
related specialties, in contact with Moore since 1959.) Audience included
Intel alumni and journalists. Occasion was 40th anniversary of "Moore's
law" which predicted in 1965 the doubling of semiconductor density
periodically, "for at least the next 10 years" (it continues today).
Moore spent some of his time on explosives, and their popularity as a
motivator for technical careers, a popularity that proves to be surprisingly
wide. That will presumably be the main interest in this note, but first a
little more about semiconductors. (First the broccoli, then dessert!)
Moore's original 1965 article in _Electronics_ (I picked up a copy)
projected integrated circuits (ICs) becoming commonplace in products like
car control systems, home computers, portable telephones. "The electronic
wristwatch needs only a display to be feasible today." He included
projections such as the curve that became Moore's Law (Carver Mead, I
understand, coined that name later), based at the time only on 1959-1965
density data. He explained to us that the whole motivation of the article
was to "sell" the idea of ICs to the electronics industry which regarded
them, at the time, as expensive and exotic, of interest only for high-priced
apps in military or aerospace. Moore provided data suggesting otherwise,
that ICs would become mainstream technology, which is obvious now,
after-the-fact. Later he mentioned some of the magnitudes of integrated
component manufacture now; 10 to the 18th power of transistors produced
annually, comparable to the number of letters in printed documents -- and a
transistor on an IC is now cheaper, on average, than a readable text
character printed on paper.
Moore was a chemist by training, and explained that he got into chemistry
originally as a child because a neighbor got a chemistry set -- "they had
good stuff in them in those days!" -- and quickly became skilled at blowing
things up. He made nitroglycerin, which he would detonate by putting a
drop on a piece of filter paper and striking it with a hammer on an iron
anvil. This made a very sharp crack, and would leave his ears ringing for
an hour or two. Moore explained that this damaged his hearing, and led to
his later relying on a hearing aid. This was around Redwood City,
California, where his father was a deputy sheriff. At one point, officials
found a collection of tools somewhere that looked like they were for
cracking open safes, and a little bottle of yellowish liquid, which had them
concerned. As Moore told it, his father called him in on the case (he was
still an adolescent) and he tested a drop of the liquid with his
filter-paper technique, and it blew. The deputies were then worried about
how to dispose of the nitro, but Moore stepped forward eagerly -- "I'll take
care of that." (He held up both hands to us, in the proud sign of the
successful explosives hobbyist: All digits present.) They also made
rockets, he said, but good rockets were difficult -- "it was much easier to
blow things up."
Later at Cal Tech when he was a grad student in chemistry, someone did a
survey and found that 80% of the Chem grad students got into it via
fireworks and explosives. Amazing!

The kids might have a "stash" there ;-)
School bureaucracies have gone nuts in recent years. Here, last week,
they decided a 17 year old couldn't carry his diabetes test kit with
him, since it had SHARP lancets.
A lawyer changed their minds real fast ;-)
I think it's time we tarred and feathered every school board member
and took our schools back to parental control.

Start by taking control back from the teachers and give it to the school board
(at least they're voted into office). One local board is trying (teachers are
now on strike for 5.8% per year for three years + reductions in insurance co-
pay).

Maybe. But there are hardly any websites that can compete with a good
textbook, quality-wise. The Internet (as this newsgroup) is great as a
medium for the exchange of ideas among people who already have a grasp
of the subject. This may of course change in the future.

Wait -- are they not any more? Explosives are (possibly) different
matter, but all this is harmelss stuff.
Don't forget potassium + water, and the arsenic mirror experiment (which
blows up most of the time).
I didn't, but the main thrill wasn't its power but the fact that one had
made actual nitroglycerine. Regular black poder or chlorate-enhanced
variants thereof had higher entertainment value. Back then (20 years
ago) I could buy most the necessary ingredients in any pharmacy (and my
father would get the others). I don't know if that's true any mor.

The little punks tried to give me a hard time, first asking, "Are you

But I got control pretty fast... took a troublemaker out in the

cause trouble I'm going to bring you out here and kick the crap out of
you, and no one will ever know."
After that, nary a problem ;-)

I don't think teachers can strike in Arizona. At least I can't recall
of any since the early '70's.

A pretty good read, actually.
Rich said:This sounds just a little bit hysterical. No kid is going to carry around
stuff that's so heavy that it will actually deform them. (they'll just
say, "**** You!") If you're talking about some kind of preschool that they
shuffle the SPMs off to before their bones are fully formed, that's the
fault of the mindless breeders.
