## Maths

generally quite dull isn't it?

I'm finding it hard to care why the Runge-Kutta-Fehlberg numerical integration method is better than the bog standard Runge-Kutta version. Can anyone tell me?

Why did i choose this for my degree?

What's your favourite numerical integration algorithm?

## I did maths up to the age of 18.

it was fucking SHIT.

## I got an A for GCSE...

## High Five!

So did I! With the A and then a U bit.

## can you understand this sentence then...

"Having a minimal number of mesh points and also controlling the global error of a difference method is, not surprisingly, in consistent with the points being equally spaced in the interval"

## Yes

What is there to not understand?

The Runge-Kutta method is ace-o, I had to use it all the time to solve the Schrodinger equation when an analytical solution was not available. I've never heard of this Runga-Kutta-Fehlberg method though but I'm quite excited about it. Tell me more.

## well...

The benefit of using Runga-Kutta-Fehlberg over the standard order 4 Runga-Kutta method is the way it efficiently estimates the local error of the order 4 method by using the method with local truncation of order 5 (meaning you have to calculate k1 up to k6), it also varies the step size to keep this error within an acceptable tolerance. This means the integration stays accurate without unnecessary calculations being needed.

At least that's my understanding of it.

## Im sitting my maths higher prelim tomorrow

All i can say is LOLgorithm!

Fuck da h8rs pi has dem dope riddims, legit

## I hate maths

but it's followed me to college and work

## I liked maths

until i did mechanics A Level and it made me go WHAT? WHAT?

I used to want to be a maths teacher until this point too

## oh how i wish

i could go back to the days of A Level Mechanics.

I apologise for starting a thread about maths, i just wanted to inflict my suffering on other people.

## well i got a C

in the end but that was thanks to my pure skillz rather than anything else...

sharing of suffering is what life is all about innit?

## A at GCSE

E at AS Level. It got hard when they took all the numbers away and replaced them with Greek letters.

## My favourite is the one they taught

me how to do at A-Level.

I have no idea what it's called.

## i got a B in the junior cert

and a D2 in the leaving cert.

is anyone else seeing a pattern here?

## something to do with The Mighty Ducks?

## how very witty.

how VERY WITTY.

## i don't believe you

## I finished all that 'orrible stuff at 18.

E at A-level.

Can't remember a thing.

Apart from my Discreet maths teacher looked like a mixture of Manuel from Fawlty Towers and Saddam Hussain.

## Maths is the dullest thing in the world

I was fucking woeful at it. Then, somehow, I got a B at GCSE. Imagine my surprise! When I went in to get my results my Maths teacher cornered me

"How did you get on, Rik?"

"I got a B!"

"Oh, nevermind"

You fucking PRICK

## I loved the maths part of my degree :-)

...can remember none of it now though.

## I loved A-level mechanics

but I'm quitting my maths degree course this week. yay!

## Purdy maths

It's art for clever people.

## Maths degree = waste of time

The only purpose of studying the uber-highbrow maths is to study it even more. My "analysis" job essentially involves using Excel all day.

But yeah, maths is great!

## Ish

although it does sometimes turn out to be useful.

In cryptography, say, computer science, physics and engineering.

But yeah, it's generally done for it's own sake... I did a 4th year masters thing and got a bit bored

## maths is totally lame

i was/am rubbish at it.

maths < meths

## you're all losers

maths is ace and 90% of the stuff you like wouldn't happen without people doing it.

Maybe you just need to admit that you're shit, because you're lack of mathematical skill means you'll never make a full contribution to society.

## yeah

because wide ranging fluid-mechanics aplication in no way benefit society?!

## Yeah,

I was gonna say, ever flown in a modern aeroplane?

## I remember very little about green's theorem

if that makes you feel any better :)

I was never really interested in applied maths though - or at least 'physical applied maths' as they called it.

Bunch of bloody differential-equation botherers who care more about your ability to apply some clever trick to an integral than mathematical beauty.

Pure maths is more fun. You get to learn really powerful abstractions.

## More to the point

why did you choose a numerical analysis course?

that stuff is only interesting if you have an interesting application for it.

I really enjoyed mathematical logic, set theory, analytic topology, category theory, some abstract algebra (although that got a bit too abstract for me), even some functional analysis, combinatorics...

numerical integration i steered clear of though.

## maths makes DiS possible

that's part of why i like it.

Also matt makes DiS possible, which is ace. Cheers matt

## Yep

maths -> me -> DiS

that's how it works.

DiS doesn't really use much maths, except in the recommendations engine.

If you want to write recommendations engines when you grow up, take all the linear algebra and stats courses

(actually I avoided stats, cos it's bloody dull at uni, but it suddenly becomes interesting and quite cool when you find something you give a shit about to apply it to)

## i LOVE maths

but hate all that analysis and stats bollocks.

## thats the only bit I like

pfff architects.

## pfffft

brick combos.

## (economist is what you were looking for)

You should like bricks, being architecty

## no

i like slate cladding and glulam frames (Y)

## i find it very difficult

(i'm not a natural) but maths is severely underrated.
