Hollywood lied to you about the moment in the Apollo 13 mission when the
astronauts asked the ground grew to double-check their maths: They did
/not/ use slide rules in that situation, but indeed pen & paper, because
slide rules don't help with simple addition of numbers.
As for divisions, AFAIK slide rules weren't used back then except for
quick estimates. Precise calculations would either be done by a single
computer requiring huge amounts of electricity, or by a room full of
computers requiring huge amounts of coffee.
Back then, computer was an actual job, requiring highly trained people.
After division, they would have learned how to interpolate using
logarithmic and trigonometric tables and stuff.
I'd also say it was good for our generation to know how to add,
subtract, multiply and divide without a pocket calculator, because you'd
probably not carry one around with you all the time back then. Remember,
we didn't have cell phones with pocket calculator apps in our pocketses
wherever we went.

Not really. The books were amazingly popular before the movies. I'm
pretty sure JKR didn't have to beg - if anyone did any begging, it was
most likely Warner Brothers.

You should really have gone to a special school of another kind. Your
parents didn't realize your math brain was running faster than those of
other kids of your age...
calculus is tough for anyone. I wouldn't ever be able to grasp it while
a teen...

Or when dealing with writing software for industrial equipment. I can't
believe how much trig I actually used when working on machinery. It was
necessary, some of the stuff I was dealing with were circles that had to
line up tangent to a board, etc..

My theory is that she discovered how to do *actual* magic, and used it to
make tons of money and fame by writing best-selling books about fake magic,
just to distract the masses.

Graphical and game programming has been quite useful in learning
geometry, trigonometry, and in some cases even calculus.

Or perhaps more like: Programming has been a good incentive to learn math?

It reminds me of the "corollary" to Clarke's third law of prediction:
"Any sufficiently advanced magic is indistinguishable from technology."

Pretty much. I don't think it's coincidence that I got a lot better at
math a couple of years after my family got our first computer. POV-Ray,
Visual Basic, and JavaScript all pushed my math skills, because there
was a real, immediate payoff to every thing I learned.

My parents followed the advice of the experts - experts who are supposed
to know what they're talking about. And hey, I can now read and write,
which is kind of crucial...

In what sense is calculus "tough"?
