She's an Engineer, and a crap one at that (graduated with a 3rd IIRC).
Tom17
But phwoar she can't 'arf compute!
the Boy From Bozlem
and she would be useful at working out how many bottles of beer and packets of smokes you could get from a fistful of change biggrin.gif
sGb27
Bah, don't you know, she secretly has a computer under her desk to tell her the answers!!!
the Boy From Bozlem
Bugger, you have just ruined my fantasy sad.gif

I thought she was doing something else with her fingers.
sGb27
1,4,7,12,50,75 ... 633 biggrin.gif
Tom17
Easy!
75*50 = 3750
7-1 = 6
3750/6 = 625
12-4 = 8
625 + = 633

Now I hope you weren't cheating there Mr Tom and only used a pencil and paper and did it in 30 seconds...
Yeti
So were the Wombles real or were there Teletubbies inside in the suits ?

Get your logic around that.

Of course! I was always great at these!*

*I may be lying as I cant do mental arithmetic for shit. I tried it for a while on paper and it was pretty fruitless.
Yeti
You have to eat loads of seeds to avoid fruitless shit.
sGb27
Wouldn't eating fruit avoid fruitless shit?
Yeti
Well the fruit wouldn't be fruity by the time it arrived, whereas the seeds just might germinate later and provide you with more fruit, thus rendering the shit far from fruitless.

Simple. They were real Wombles. The Teletubbies weren't even a glint in Old Man Teletubby's eye back then.
Yeti
Thank god for that, I though the tubs had discovered time travel.
Tom17
Whenever I see the London tube running on outside tracks, it always makes me think of Wombles

edit: Tracks, NOT treadmills!
Tom17
Also, in the interests of keeping this thread going on and on and on, I will soon have a question regarding the behaviour of the laminar flow in my tea when I stir it. I have made a strange observation but wish to make more observations before I pose my question to y'all.
sGb27
How come the moon affects the tides much more than the sun? Given that the gravity force from the sun is bigger than from the moon. I have yet to see a decent explanation for this one...
Tom17
Not sure, but I am trying to compare moon positions with this tea-strirring phenomena to see if it has any relevence on when the phenomena occurs.
Pirulero
is there still a huge prize for anyone coming up with almost perpetual motion? and how come all those clever office gadgets that keep going for ever can't be used to power something? I suppose it's a friction thing right? But how come you can't make millions of tiny things that work and combine them to power stuff? using gravity or whatever...
dolfan
The moon has a known raction to brewed tea, but only if the the tea is on a treadmill. Weird I know.
sGb27
Don't some of them have batteries in?
Tom17
What office gadgets keep going forever without energy input, exactly?

edit: I'm being serious about the tea!
sGb27
You know Tom, the ones with random bits of bent metal and magnets and shit. You set them off and they go back and to for ever. I have one that my great grandad started in 1879 still going today right here on my desk.
Sin
Word just in...

The plane WILL NOT take off.

Fog!
sGb27
If the conveyor spins at 62563.5mph it will generate enough heat and wind to clear the fog.

Ahh yeah, perpetual motion using magnets, course.

@sin, I did not realise the question stated the plane is at LHR

Name me another airport with a conveyor belt THAT long? ph34r.gif
Tom17
Doesn't Charles De'Gaulles have long ones?
Sin
That's not what the girls at The Moulin Rouge have been sayin'. wink.gif
