Was the fall of the Roman Empire or, as often predicted, the coming fall of the American Empire, numerically predictable?

It is, according to research led by Sergey Gavrilets, associate director for scientific activities at the National Institute for Mathematical and Biological Synthesis and a professor at the University of Tennessee-Knoxville published in Cliodynamics: The Journal of Theoretical and Mathematical History.

How can a man who writes an article noting the many positive strides made in eliminating gender discrimination be sexist?    Well, he isn't, but men who go out of their way to help women can be considered sexist, thought it is a more benevolent sexism than the real kind.

New research from the University of Granada warns about the negative effects of "benevolent sexism", a term used for apparently positive ideas and attitudes of men towards women, which are based on the assumption that men must take care of and sacrifice themselves for women.

I am taking part in discussions with Sascha Vongehr about the MIT video - here on this site -

From my post there:

Nanotechnology is my own field of research for 12 years now. It is one of the, if not the most important of the emerging technologies, and it is widely believed to be the vital ingredient to many by transhumanists desired transformations, be it slowing down aging, computer to brain network-neuron interfaces, or the development of ever faster (quantum) computers. Nano is still the big buzz word and I am afraid to have become the uninvited party-pooper.
