WoW 3: Integer Sequences

Having had a couple of more obscure sites, I thought I would put in an absolute classic: The Encyclopedia of Integer Sequences.  This wonderful resource shows the immense power of online databases.  A geeky… Continue reading

Angle sum formulae

Only a short post this week.  I am on holiday for a few days from tomorrow.  Yippee! In playing with algebraic equations I found myself wanting the angle sum formulae: Being a forgetful… Continue reading

Surfaces 1: The ooze of the past

Curves and surfaces are a wonderful visual representation of mathematics. They can move from the simple and profound to the complex and intriguing. They have even been accused of being part of a sinister plot. In addition the mathematics behind them is becoming increasingly useful in many areas, algebraic statistics for example.
