What does he mean by a.bxc?
Soooo confused >.<

Also, bump

@stuk - haha, sorry!
@Le_Roi - google...
@sqrg - Argh, horrible visions

You suggest google as an alternative to studying vector arithmetic. Figle, I'm ashamed of you.

So whenever any Diplomacy chicks are up for a game of Strip Diplomacy, let me know ;P I'm sure we can work out some rules!

@a.bx - Well, I doubt he even new it was *about* vector arithmetic.
@Le_Roi - Study Vector arithmetic.

>.<

Looking a lil rhombic there, a.bxc!

@Le_Roi: don't give into it man, studying vector arithmetic won't get you girls!
bumbitybump

It'll get you vector arithmetic girls!

Time to fill in the blank, everyone!

Vector arithmetic girls do it...

Goodness, it has been a long time since I studied vector arithmetic. Why do we talk about definite and indefinite integration while we're at it and start rotating trigonometric functions about axis (a little Calc 101 there)

when crossed?

Why would you want to rotate a rotation Draug? Seems kinda pointless to me.

@//: I'm guessing you're a graduate, but where from?

Well, SIN rotated about the X axis, with the right modifiers, can be used within the right limits to computer an American football's volume (roughly).

True.

If a girl isn't seduced by a tasteful piece of vector arithmetic then she's not worth seducing. That's been always been my motto and I'm sticking to it.

Screw seduction, liquor them up then lick them up. hehehe

Way to stick with ur principles a.bxd.
Admirable, but i feel Draugnar's system has a higher succes rate ;)

+1 Parallelopiped. Incase you didn't see last time, where did you go to uni?

@Draug, you could also just put the football in a fish tank and measure the change in water level. And then take the football outside and throw it around with some cute coeds.

@Draug 2, reminds me of that old bar sign. "Liquor in the front. Poker in the rear".

@Ald,Draug - Aren't you two married? [clearly not to each other, but you knew that - only putting this to stop someone being difficult!]

I am yes. And catching coeds is a theoretical to me as strip diplomacy. Fun to talk about and imagine.

But I do have a few footballs of different sizes so if I wanted to figure out how they compared to an official football, I'd probably go the fish tank route, and not just because my calculus is so far in the past that I couldn't tell an asymptote from a hole in the graph (or a pun more in line with calculus if you will.)

@figle Oxford and Harvard (I thought I ought to try out one of the Cambridge universities and I couldn't bring myself to go to the red brick poly in the fens)

And you became a maths teacher? :S

I believe maths teachers should be good at maths. I believe that quite strongly and so decided to stick up for my principles by ensuring that at least one is.

Alderian's answer applies to me as well. Besides, I'm 44. Not many coed's gonna look my way unless I flash a lot of money, lose a bit of weight, and update my wardrobe. Even then I'd just be getting the gold diggers looking for a sugar daddy. At least I still have a full head of hair and can readily color out the gray.

@Alderian, but seeing as a football floats, how would you submerge it without accidentally getting some displacement from the tool used to press it down? What I would do is use two identical tanks, and use a touch of CA to glue the inflated football to the bottom of one. Fill the football one to overflowing, then siphon off and drain it into the second so you could see the difference and get the volume.

Make a cage on a stick out of metal the right size to hold a football. Submerge cage in full tank (use stick to lift cage out of water - ensure when submerging cage that stick is kept vertical). Pull out cage and allow to drip dry (best do this in a completely saturated atmosphere to ensure no evaporation). Put football into cage and lower cage once more into tank (ensuring stick is kept vertical). Volume of water displaced second time round is equal to volume of football.
I saved you a tank.
You owe me a tank

Use a noodle strainer to push the football down. The holes let you see when you've pushed it down to just the top of the water.

Or, just put a piece of metal across that you can lodge the football under. Fill the water up to a certain level and mark it, then reach in and remove the football and mark the now lower level. Make sure to use a can of air to blow any excess water off your hands and the football back into the fish tank.

Or, use one of those big tanks that a person can be totally submerged in and then use a coed in scuba gear and naught else.

Of course, you could inflate the football with something heavier than water (sand to start and add water till pressurized?) so it just sinks then make a platform out of hollow material in a honeycomb pattern (negligible mass and volume but enough strength to hold the football as it is lifted out) and attach thin monofilament to the corners to lift it out (also negligible volume but enough tensile strength to lift). Or just CA the monofilament to the two ends of the football.

OK, I go with the coed in Scuba Gear and naught else. Of course, this works best if it is an entire lingerie football team in scuba gear - sans the lingerie.

@parrellelopiped - Wow, lots of respect to you! All the way through school I remember thinking how lucky we were that our head of maths was so good. Other teachers in the city all looked up to him, and scarily so. We went to a revision event last year, and they were talking and helping etc, then he walked in and it was as if he was *their* teacher!
