The Butterfly Effect : the idea, proposed by Edward Lorenz in 1972, that the flap of a butterfly's wings in Brazil could set off a chain of events which could lead to a tornado in Texas. Lorenz was one of the proponents of Chaos Theory which (some say) has 2 main postulations:
1. even complex systems rely upon a simple underlying order;
2. even trivial actions can have major consequences.
This seems to be somewhat relevant to History!
I was keeping this page 'Public' to provide (on the menu shown by clicking 'Events & Trends' on the right) a link to the 'Kings & Queens' pages that will be kept after the present restructuring exercise has been completed. Now that that link is being provided on the Extra Content page, there is little point in keeping this page but I am doing so, for the moment at least, simply because I am rather fond of the above 'butterfly effect' note....
