You could look where Ray Kurzweil gets some of his data points for "The Singularity is Near". If you serious you could check around for a similar academically compiled list of "significant" historical events. (I think Ray mentioned doing something just like this...) Further more, I'll mention there is some crazy Russian who thinks our modern calendars (Gregorian) are an elaborate hoax. But, as I understand it, he had someway of applying algorithms to historically "significant" data points. (If you're actually interested, reply and I try and find his name again.) ...FWIW
