I am pleased to announce that you can now download and view any of the (draft) chapters of Mathematical Olympiad Dark Arts. Any comments, corrections or suggestions you send me would be greatly appreciated. I’ll incorporate these into the book before publishing … Continue reading →

Here’s the penultimate chapter of Mathematical Olympiad Dark Arts. This includes several methods of solving Diophantine equations, including Vieta jumping and the Sam Cappleman-Lynes Technique. Also included is an explanation of how to locate rational points on algebraic curves, up to and including elliptic … Continue reading →

On Tuesday (23rd October) at 7:00 pm, there is a monthly MathsJam gathering. It occurs simultaneously in various areas of the country, including the Castle Inn, Cambridge. I’ve heard rumours that there is a surprise party at the event for Tom Rychlik to … Continue reading →

Yes, there’s another draft chapter of MODA online. Before we get to that, however, here is a picture sent in by arguably the greatest fan of cp4space: You may remember Vishal from the games of Hackenbush he played against his adversary, … Continue reading →

A tried and tested technique for attacking geometry problems is ‘bashing’ them with an algebraic approach. We’ve already seen how projective geometry can be based around a coordinate system (giving rise to areal and projective Cartesian coordinates as special cases). Two-dimensional Cartesian coordinates … Continue reading →

(This is a pre-recorded message scheduled to automatically publish on the 1st October. If you’re reading this, I’m in Cambridge, probably either very busy with work, or very inebriated, or both. Here’s an emoticon which is also valid punctuation in this … Continue reading →

I imagine you’re all eagerly anticipating Cipher Tuesday, which is only a couple of days away now! Meanwhile, the sixth chapter of MODA, namely ‘Inequalities’, is available for download. Preface Combinatorics I (enumerative and geometrical combinatorics) Linear algebra Combinatorics II (graph theory) Polynomials Sequences Inequalities Projective geometry … Continue reading →

It’s reached this time of week again, so I’ve uploaded the fourth and fifth chapters of Mathematical Olympiad Dark Arts. Enjoy!

The second and third chapters of Mathematical Olympiad Dark Arts can now be downloaded for public review. Preface Combinatorics I (enumerative and geometrical combinatorics) Linear algebra Combinatorics II (graph theory) Polynomials Sequences Inequalities Projective geometry Complex numbers Triangle geometry Areal coordinates The … Continue reading →

After several rounds of editing and peer-review, I have decided that my book, Mathematical Olympiad Dark Arts, has reached a point where it is suitable for public review. Rather than upload the entire 176-page document in its entirety, I shall … Continue reading →
