Non-ergodicity and diversity

Ergodicity is the condition wherein a sample is representative of the whole vis-a-vis some statistical parameter. An ergodic system is one that visits all possible states of its existence as it evolves. Axiomatically, a non-ergodic system is one that does not. Stuart A. Kauffman, a scientist at the University of Calgary, wrote on Edge a… Continue reading Non-ergodicity and diversity

The journal's Twitter handle had tweeted it thus: "Do you think publishing on preprint servers is good or bad for science?" Though the question immediately set… Continue reading Silly arguments to restrict access to preprints

To say "nature is Lovecraftian" is to extend to zoologia the out-of-place characteristic we associate with Lovecraft's… Continue reading The surprises
