Patterns in nature result from dynamic relationships of forces and constraints. What is analogous for patterns in art? Art is created by human hands motivated by inspiration and thought. It is the product of creativity and skill. Creativity is constrained by cognitive processes and skill by the limits of technology. Based upon the author’s studies of Oriental carpets, this paper suggests that p...

Incomplete Nature is about an important and difficult subject: how life and mind evolved from a world of inanimate matter. It is also about what are the right concepts to use in understanding the nature and workings of life and mind. We need to be able to conceive them in such a way that it becomes intelligible that they could have arisen naturally from the kinds of inanimate processes describe...

Observations of the Milky Way at TeV--PeV energies reveal a bright diffuse flux hadronic cosmic rays and also point sources gamma rays. If gamma-ray are cosmic-ray accelerators, then they must be neutrino sources. However, no have been detected. Where they? We introduce new population-based approach to probe PeVatrons, demanding consistency between point-source PeV-range data on rays, neutrinos...
