Well, that's not a very cheerful attitude. Just keep the engineering

What, dont get Northrop Grumman to do half the calcs, NASA the other half?

Yup. Without delta-epsilon proofs, calculus is just a bunch of

Newton and Leibniz made do without delta-epsilon techniques to invent the
calculus. Newton's "infinitesimal" has apparently been put on a rigorous
footing. See the many links to Abraham Robinson's Non-standard analysis.
Most mathematicians don't seem to see any advantage to leaving the limit
techniques.

Not much to understand, really. The point is to get the ball across that
line when you're on offense, or stop the other team from getting it
across your line when you're defense. They switch back and forth
throughout the game. :-)
The rest is just gingerbread, much like calculus. ;-)
(big hint - be in the presence of males while watching - how they react
will give you a pretty good insight as to what's "important".)
I THINK she was going to think about how the TV works.

Oh, but "How does it work?" opens such a wealth of possibilities for
understanding stuff! How does "Calculus" "work"? How does "The Heisenberg
Uncertainty Principle" "work"? How does "Relativity" "Work?"
And how does a freaking gas refrigerator work? ;-)
So, naturally, I assumed that SciGirl meant, "How does football work"? I
figure a 14-year old scientist would have TV down pat already. ;-)

I have a friend who is 13, will be taking trig and calculus next year,
and is capable of understanding it but just doesn't care enough about
science to do so. She helps me with math, I help her memorize the
periodic table. She's got it to zirconium now, I think.
Also, no, I actually do not think I'm smart at all. It's not like I
just read it and get it. As I said, it took me three months to get
relativity. I had a report card full of C's in 6th grade and worked
hard to pull it up from there. If any one of my mentally normal
classmates loved science as much as I do and really wanted to learn
this stuff, and put the effort in that I did, I'd be willing to bet
they could, too.
The biggest reason people don't want to believe that you're 14 is that
you're writing coherent English. And you seem to have humility. The entire
group is gaping in awe at such a phenomenon. ;-)
When we were 14, we were lucky if we could pick our nose without putting
our eye out. ;-D

Well, when _I_ was 14, I had already learned the difference between my
nose and my eyes. ;)
But you're not Grise.

Ah yes, but you missed his 'we' and my '_I_' ;)

Yes I missed that, but it's gross! Grise wee'd in your eye? I knew he
was strange, but you?!

what the link is
between light as a particle and light as a wave.
Light isn't EITHER a particle OR a wave. It is something more
fundamental, that sometimes BEHAVES as a particle and sometimes as a
wave.
We can only describe things that we can't see and touch in terms of
things we can.
|
Don't forget things we can imagine, things we can intuit, things we
can know by the feeling-sense, a la "gut feelings", and so on. I know
these things are real - there have been at least two separate occasions
when a premonition has prevented me from causing bodily harm to an
inattentive pedestrian.

The *next* stage? Isn't "limit theory" inbetween there somewhere? If
one has no appreciation for "infinity", "zero", and "almost" one cannot
appreciate calculus.
No, you are making it too difficult. You don't need anything as $10 as
'limit theory' for differential calculus, just a drawing showing a curve
with a chord and a tangent.
|
Ok, I'm all ears. What's the area inbetween? What's the area of the
circle?

"wave" and "particle" are just words that make sense within the limits of
the respective model within which they're used. Once you've mastered the
basics of quantum mechanics you'll find that it doesn't really matter what
you call it, it just falls into place quite nicely.

This is not "Google Groups". This is Usenet. And had you "lurked" in this
forum for a while before posting your questions, you'd have found out that
calculus-heavy postings are almost non-existent (I can't remember having
ever seen one).

I don't think she's a day older than 14. She comes in here, posts a lot
of precocious stuff and gets all sulky if people don't treat her as a
fellow adult. All smart kids are like that. She'll grow out of it like we
all did.
