For those who started following this blog within the last twelve months and there are quite a lot of you, I write three posts every year as my Christmas Trilogy, although they didn’t acquire this name until 2012. The First on the Christmas Day is for Isaac Newton who was born 25 December 1642 (os). The second on St. Stephen’s or Boxing Day is for Charles Babbage who was born on 26 December 1791. The Trilogy is rounded out by Johannes Kepler who was born on 27 December 1571. If you want to read the earlier posts you can find them here:
Reading that lot should keep you occupied for a couple of hours.
