Let me set it up for you:Three people are in some competition run by some maniacal billionaire. If they "win" they get £3,000,000 between them, but if they lose, they leave with nothing (or get thrown to the sharks with lasers on their heads, whatever floats your boat).The rules of Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com1tag:blogger.com,1999:blog-4337488554466977439.post-79610792236830453522007-05-02T12:24:00.000+01:002007-05-02T12:32:49.327+01:00I'm back!Hello to anyone that reads this (Ok, so that's going to be my mum and a few members of the Warwick Mathematics Society), I wanted to (finally) update everyone with what's been going on, and why there have been like... no posts here of late :)Basically, the Sunday before last (22nd Apr), I was cooking a risotto with Emma (my girlfriend) and managed to miss the onion and cut straight into my fingerJebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com0tag:blogger.com,1999:blog-4337488554466977439.post-10682285350590350762007-04-16T14:23:00.000+01:002007-04-18T02:39:51.842+01:00A bad Biffy Clyro cover I made - Wave Upon Wave Upon WaveHey all, this is a bit of an odd post for this blog, but what the hey, I made a cover of Biffy Clyro's Wave Upon Wave Upon Wave after having seen them twice over the weekend :D I'll put some reviews of the gigs up here in due course, but for the time being, enjoy(?) the cover!If you want to get a good version of the song (the original!) then the album you need is Biffy Clyro's "Infinity Land":Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com0tag:blogger.com,1999:blog-4337488554466977439.post-72517472417588636822007-04-14T16:45:00.000+01:002007-04-14T17:24:48.861+01:00Book Review - Numbers And Functions, R. P. BurnThis is the first of my book reviews, aimed at current undergraduate mathematicians, especially those at Warwick University.For my first review, I will be looking at one of the recommended books (nb. link only works for Warwick Mathematicians) for Warwick's 1st year Analysis I & II course - Numbers and Functions: Steps to Analysis by R. P. Burn.This book covers all areas of basic analysis and Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com0tag:blogger.com,1999:blog-4337488554466977439.post-31001285303940861102007-04-10T16:14:00.000+01:002007-04-13T19:03:01.445+01:00Beatie Boys, Foo Fighters, RHCP to play Live Earth UKRight, I just saw this posted on the Wii news channel, and just had to pop it up here. This one isn't from the world of Maths or Computers as normal (although it did come from a Wii...).The lineup for the UK portion of the Live Earth concert has just been announced, and what a lineup it is - Beastie Boys, Foo Fighters, Red Hot Chili Peppers, Bloc Party, Razorlight...

This post aims to explain Julia Sets and some related results in a manner which is graspable by a first year mathematician or so. The prerequisite knowledge really for a basic understanding is Complex Numbers and Functions.To find a Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com3tag:blogger.com,1999:blog-4337488554466977439.post-83596013837506854242007-04-02T16:03:00.000+01:002007-04-02T16:43:18.575+01:00Essay Update - The Böttcher IsomorphismRight, I'm now at the point in my essay that I need to explore a theorem known as "Böttcher's Theorem." What Böttcher's Theorem states is that given a function of the form with and , then there exists a local holomorphic change of coordinate with which conjugates to through a neighbourhood of . Furthermore, is unique up to multiplication by a root of unity.So, what does this mean?

I advanced slowly and rather haphazardly, picking up bits of BASIC, VB, Java, SPLUS, C++, Prolog, MATLAB blah de blah blah. The main problem that I had was that that I only ever programmed at random, and never had any real Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com0tag:blogger.com,1999:blog-4337488554466977439.post-45628612037605338472007-03-28T10:32:00.000+01:002007-03-30T09:42:57.466+01:00Essay Update - My 3rd Year EssaySo, this is the first of my essay updates, aimed towards mathematics students. It is partly a selfish plan, I have to admit, as it will allow me to keep myself focussed on how I want the essay to progress.The outline of this essay is the study of external rays of Julia Sets of polynomial maps, and then later to extend this on to the Mandelbrot Set. An external ray is, in laymen's terms, the Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com2tag:blogger.com,1999:blog-4337488554466977439.post-72461550336557256322007-03-25T15:03:00.000+01:002007-04-18T02:44:30.915+01:00OpenOffice.org - For University StudentsSo, I’m going to give a brief overview of the OpenOffice software – a free open source office suite for Linux, Windows and MacOSX. This review is aimed at University students. I first used Open Office in the Linux room of the maths department of my university in my first year, and at the time, although it was adequate for reading and editing Word docs, I found it was underpowered compared to Jebhttp://www.blogger.com/profile/18105399542771198198noreply@blogger.com0
