2i or 2j, depending on what science you're studying...

And they are used in a hell of a lot beyond mathematical proofs...

what the deuce! there isnt actually an answer to the question is there? i thought it was just an impossible number quite simply! youve blown my mind...

i dont really know anything about matematical proofs, are they used in general equations then aswell?

You almost certainly wouldn't be using a computer now if there wasn't a 'solution'. They are used extensively in engineering (especially electronics) and quantum physics...

theres no chance all u people new this without a serious bit of googling or sumthing, in my mind it was as simple as a number cannot be both a positive and a negative end off.

therefor it is an impossible number, but no! you lot had to ruin it.. wish id never posted oO (jkin)

im willing to concede one of you, probably jah128 actually knew about this.. but thats it, well maybe 2i people but no more!

To be fair, anyone who studied further maths at A-level, physics or any maths/physics/engineering subject at uni will certainly have dealt with them, they are pretty widely used.

Seeing as I am doing a Masters in Physics you can concede that I knew it to :p.

hmm i did geography, biology, DT and then Geog environmental consultancy so have managed to avoid them... started with physics at A level but dropped it and certainly dont ever remember comign across them before... i dont like there being an answer though!!... prefer the idea of an impossible number that has to be both negative and positive....

i can concede you knew it too bigfoot, jsut making me feel liek a right dumbass here with all ur answer though lol

tbh it still strikes me a little bit as cheating as the letter i is just a symbol for SQRT(-1) from all accounts above, so the answer is like a little mini formula within itself,

that makes me a little more satisfied, i feel i can nearly argue again

Not exactly on topic....but... I'm always very impressed when people talk to each other in mathematical terms. I have no idea as my maths is only O level standard.

I really didn't get the hang of the maths for, for instance, mean free paths, for Chemistry - just had to learn it the best I could; I always thought it was good to be able to describe something far more precisely than in 'language'.

chesso youve just exploded my brain for the second time tonight... thanks.

hows ur photo thread going btw? i havnt dropped by in a while

Im probably wrong, but I like to look at things like this in a simplistic way.

-4 is the same as your friend owing you £4 to buy 2 pints....but when he says he will give you the square root of his debt back (and hands you over an Orange & Mango j20) you respond by giving him 2 shiners in return.

You mean 'too' ;)

You're welcome

The thread is good!! The theme for the comp on the 31st is 'Water'. Get snapping. :)
