Most of it, yes. But places like IBM, Intel, etc have R&D divisions.
They don't just plug and chuck numbers.

I know one person who interviewed for a financial firm. He was telling
me about it, and said something like:
"They asked if I knew any Haskell. I've never heard of it. Have you?"

What part of Oxfordshire is not in the UK?
What does internationally renowned have to do with it? They have an
office in the UK. They'll need people to provide support from within the
UK. They perhaps do consulting for their clients every time they get stuck.
Just because they're a big company doesn't mean that they don't have
all kinds of jobs - both big and small.

You may want Mathematica to help set some of it up.

Well, someone spent a whole s__tload of money building the LHC, and Cern has
been around for decades. Someone is doing theoretical physics for money.

Depends, really. If you're trying to come up with the best airplane wing,
there's a lot of math involved.

Never hurts to apply. And maybe they'll tell you who their customers are
enough to apply for a job nearby.

Someone has to figure out all the other stuff like that.

Try it and stop running yourself down. They have an office in Oxford.

Yeah, about that... I forget how much it cost to build the LHC, but I do
wonder where the *hell* they got the money, considering that they're
just a bunch of scientists. Last time I checked, nobody pays money for
finding out how the universe works.

Really? I assumed it was just a question of running different designs
through the simulator and seeing which ones have the best properties.

Are you seriously suggesting that there are problems that are unsolved?

You checked that? How? When? Sources?

Yes, but you have to find the formulas first. Suppose you need to
account for a non-linearity in the system you're controlling to get
precise positioning. Say, for the sake of example there's no way to get
around the non-linearity. Also, for arguments sake, lets say the
designer doesn't have a fancy cad application available, so can't just
give you a formula.

Actually, because it's readily available in the field.

I've used a tape measure on numerous occasions. I've also used a small
ruler clamped to a bar of a known length to find scaling factors for a
machine.

The chances of not having "fancy CAD software" available and yet having
a sophisticated and highly niche product like Mathematica seem rather
tiny...

A ruler for measuring things I can believe. But for drawing straight
lines...? I doubt it. ;-)

All that money they used to build the thing? They spent it on people
working, rather than welfare.
And yes, what do you think the Hubble is all about, if not figuring out how
the universe works?

How do you know what the simulation is supposed to do? You want to simulate
(say) a rocket launch? How are you going to do that if you don't know the
formulae for a rocket launch?
> Are you seriously suggesting that there are problems that are unsolved?
Yes? Lots, even? Even lots that have been unsolved for a long time?

I must admit, I've often wondered where the hell they got the money to
build Hubble, given that once it's built it generates no income...

I'm not understanding what you're trying to say.

I'm aware that there are lots of problems in science and mathematics
which are unsolved, but I was under the impression that things as
mundane as figuring out what shape a wing needs to be are not amoung them.

It's a tiny, tiny percentage of the cost of anything else. There's only one
Hubble, so it can get pretty expensive before you have to worry about it
becoming anywhere near "expensive" in government terms.
> I'm not understanding what you're trying to say.
I'm saying, how do you build a simulator and be sure the simulation is
correct enough?

Figuring out how far away the detectors in the LHC have to be from the
collision? Figuring out a good antenna shape for an 802.11x 397MBps wireless
router? Figuring out the right shape for the wing of an orbital ship that's
going to be coming back into the atmosphere at 35x the speed of sound?
