OT: Mathematical Conundrum III

I rather suspect it'll be the OP who qualifies for this particular 'honour'. :-)

Well there's little point in sinking the boat.

It's mostly the vodka that does the job.

I wasn't taught how a screwdriver works at school, and last year I was asked if I had any minus screwdrivers, do you know what they are or how to use them ?

[John Rumm]

Indeed, and reading in general is a very big part of that... its sometimes very easy for those of us with a technical disposition to dismiss "shakespeare or virtually any other story book", when in reality there is a wealth of knowledge and understanding contained therein, not least training the mind to think and analyse.

One of the nice things about the physical sciences is the ease with which one can make the subject "come alive" with practical demonstrations. You know you have found a truly good teacher who can do the same but with other non demonstrable subjects.

Do you have to? Couldn't you just stop?

[Cursitor Doom]

Can't. Too much public demand.

[Paul Herber]

There is a valid conundrum for you: Can zero ever be too much?

[The Natural Philosopher]

Absolutely!

ah, so that descriptoon was not unique to a teenager at our theatre. when asked whaqt he meant he said "not a positive one" (Posidrive) The blade could be sonsidered as a minus sign.

I find motorists do emergency stops for people walking PAST zebra crossings. I don't stop unless someone is already waiting and looking across the road, or at me to see if I'm stopping, and if I can stop without braking hard.

[Tough Guy no. 1265]

Or less fines for motorists.

[Tough Guy no. 1265]

Your name has changed back.

[Tough Guy no. 1265]

No it wouldn't, the wheels would fall off first.

A flat bladed screwdriver ? Those symbols for Phillips and other cross head screwdrivers look like plus signs so somebody with a logical mind but no practical experience on seeing a drawing or set of instructions with symbols for a slot head screw might ask for a "minus" screwdriver. Aren't they mainly used as emergency chisels.,wedges and miniature crowbars nowadays.

Good point.

Getting lids off old paint tins (usually by driving them through the lid in my case).

[Tim Streater]

Don't you just heat the tin until the lid pops off ?

[Jim_S]

Tried it with a plastic one. It didn't work. Wife's not speaking to me.

ARGH! Please, no. Seeing dy/dx still gives me nightmares :-)

Matrices and tensor calculus is where I glaze over.

[Tim Watts]

I loved matrices - but tensor calculus broke my brain...
