Incredible how time flies. I thought it was last year that I commemorated the birth of Sir Isaac Newton, but it was as long ago as 2007. So, clearly it is about time we again celebrated the greatest person ever to be born on the 25th December. Happy Isaac Newton Day!
[For any clever dicks out there: Newton was born on the 25th December, not the 4th January - England didn't change over to the Gregorian calendar until long after his death.]
