In particular, the requirement of a unitary representation of the Poincaré group is pretty strong, and may not hold in the kind of general context of interest in quantum gravity. Just search for CPT-violation on the arxiv to see what I mean. But there is a sense in which something “like” a CPT theorem probably will hold in physics beyon…

Cosmic Variance is (Caltech physicist) Sean Carroll’s frequent cyber-stomping ground. Apart from the general entertainment value of this blog, it is of special interest to for both its physical and its philosophical content. Backreaction is one of my very favorite blogs. Sabine Hossenfelder and Stefan Scherer (Perimeter Institute) prov…

In the last two decades, applications of group theory have surfaced in biology and in medicine as well. For example, groups have been applied to population genetics, epidemiology, neurobiology, and even anesthesiology. However, few of these applications have been very robust. Most deal only with comb…

What happens when that kind of carefree creativity and affinity for science are set loose on raw, practical problems? Nathan Myhrvold seems to have asked this question, and then systematically implemented an answer, in a company called Intellectual Ventures. The first part of…
