Isaac Newton claimed that it was the summer of 1666, in his mother's garden that he saw the apple fall from a tree that became the legendary inspiration for his mathematical interpretation of gravity. Admittedly, his Principia Mathematica was published much later, but I believe the moment of inspiration deserves to be celebrated.
Interestingly, the reason he was at his mother's house was to flee from the great plague of London that summer. Luckily he survived, for if he had remained in London and died of the plague who was the next possible genius to give us the equivalent of Principia? How many hundred years would we have waited? Would our understanding of gravity be so limited that we would still be waiting for space travel?
Well I decided to mark the occasion with a cartoon and publish it in my local astronomical association's newsletter. So here is my take on the events leading up to the summer of 1666 (ignoring the truth in Black Adder fashion). Click on the cartoon to see a larger version and enjoy. Long may we revere the apple.
