Selly Oak Hospital Can Always Handle The Occasional Accident is another one.

I'm off school today as I'm ill. :cry:

Having said that, it's not all bad as I get to miss maths. Yay!

I used to remember it with:

The Old Arab Sat On His Camel And hiccupped

Jeez nearly 23 years since I took my Maths A level :roll:

All of a sudden I feel old (41 tomorrow

My lawyer said he could get me off being 40 with a fine, but the judge thought otherwise :cry:

my birthday is tomorrow too. suppose it's not that random. with a few thousand members it has be a few peoples birthday everyday.

ok, maths problem: is a union of infinetly many closed sets closed or open?

Closed. I mean open. No! Closed! Argh!

Should this steam be coming out of my ears?

there's so many maths things like that. just try explaining to someone why the multiplication of positive and a negative makes a negative, but 2 negatives makes a positive, and all that jazz.

or i could rant about hyperbolic space, and how a triangle in H-Space can have all it's angles to be zero, all the sides to have length of infinity and an area of,.... (no, lets see if anyone knows that, have a guess)

and does anyone know of a decent way of visualising things in 4-D? i just can't get my head round it, just 3-D pre-imaging really, which still is mad!

The answer is 4

by **nickj** » Mar 15th, '07, 23:47

You're having problems with 4 dimensions? Have you tried the 10, 11 or possibly 26 that are predicted by string theory and m-theory?

(I'm not saying that I have by the way; undergrad physics doesn't really get you that far and my masters was miles away from the subject)

How's your binary fractions Tomo (or anyone else for that matter)?

Isn't the 4th D time or am I being a bit dense? Please don't say it's i or e. I can't d o i. Or e. Me back won't stand all that dancing, and the smiling gives me jaw ache. And I'm not spending 4 quid on half a bottle of tepid water when all I want is a sit down despite how far the disc jockey can get his arms in the air in time to the music.

The answer is always either: '42', 'yes', or 'who cares'.

But in all honesty, i understood some of that stuff that Lawrence was talking about! Like the multiplication of negatives, and the randomness of his birthday! Happy Birthday by the way dude! All the rest made me feel like if i thought about it much longer, i would turn inside out.

Night dudes!

by **Lawrence** » Mar 17th, '07, 11:32

the madness is i do a lot of work in like 20 dimensions or something, but the idea of visualising it is shear lunacy! still can't quite do 4

as for string theory: i thought super-string only needed a 20-Dimensional space to hold? regular string theory only uses about 10 or 12 i think

by **nickj** » Mar 19th, '07, 20:39

My (very limited understanding) was that string theory required 26 whilst superstring and M-theories need about 10 or 12, but it all depends what you are trying to do with them.

How hard can a binary fraction be?
