A year’s work, lessons learnt

October 11, 2010

I’m back!  And rather surprisingly, I seem to have gained a lot of readers in my absence.   Having not even logged on to WordPress for a few months, I have returned to see that my google reader subscription rate has doubled, and the number of people visiting the blog has increased by more than at any point since I started writing it.  I’m not really sure what lesson to take from this.  Probably it is just the natural result of a gradual snowballing effect: over time more people click on your site, the google rankings go up, causing more people to click on your site…

Then again it’s  possible that people just prefer it when I don’t write anything!  Well I’m sorry those people, but I intend to start again.  Although possibly even more erratically than before.

Anyway, I will explain the terrible sequence of events which led me to abandon blog shortly, but first, a shameless Rupert Murdoch-style using of one of my products to promote another! (I would do this at the end, but am rather doubtful as to how many people actually make it to the end of my posts).  Having been introduced to Vietnamese coffee by my father-in-law a while ago, I have utterly fallen in love with it, and realised that it is very difficult to find here in the UK.  So I have set up a (very) small business selling it.  The website is here.  Try it!  You won’t be disappointed.

Sorry about that.  Now, this is what happened.  Having struggled with the proof of a knotty mathematical problem for the better part of a year, I was advised by my supervisor to publish what I had.  So I put the paper on the arXiv (an online preprint archive), not really expecting to achieve anything, but generally wanting to share the knowledge out of a spirit of altruism (and self-promotion).  Within a few hours of it appearing, a certain Peter Mueller had read it, and proved the last part of the conjecture!  (So there you go doubters: people do read your preprints).  This was wonderful news; we invited him to be a co-author, and set about writing a final draft. I also wrote a whole long blog post about how great this was, and what it all meant.  But then a couple of days later Prof. Mueller sent me some rather less good news: he had found a  mistake in my work, which completely invalidated the whole thing…
