Cambridge Chat (previously New Cambridge Students Entry 2004)

by the way.. anyone... Is there anywhere in cambridge that sells sewing type stuff? I need a hook and eye and some black thread in an experiment to try and make my gown wearable...Like any big dept,. stores should sell that kind of thing, but i dont recall seeing any?!

devilchild....if you havent managed J9 by now, here's the answer I just worked out:

a rotation by angle t is multiplication by a complex number: p = cos t + isin t (since arg(p) = t)....therefore

z1 rotated = z1p
z2 rotated = z2p

taking these new values for z1 and z2, then (New z1)(New z2)* = (z1p)(z2p)* = z1z2*pp*

but |pp*| = 1 (obviously) and arg(pp*) = 0, therefore z1z2*pp* = z1z2*, so is invariant!

how how how!

tick 5 was a piece of piss...will only take you 10 mins

Oh, I've just discovered a new unspeakable well of loathing.

Just had a lecture on how to become immortal! Mwahaha (evil laugh!) but this website is more distracting than I feared, they mentioned stuff on apoptosis and all I was thinking was what you medically/sciencey people were discussing about it a while back!

Still ill my mum was even suggesting she come and visit, not that I can actually see that making any difference to my health

Tick 5 has already taken me 2 hours. I'm sure it should be this, but ML disagrees.
