Springer Publishes Crank ‘Proofs’

…nce or arguments which contradict their unconventional beliefs. (Wikipedia.org) Two propositions, Fermat’s Last Theorem and the Goldbach Conjecture, truly stand out among cranky topics, in drawing the vast majority of bogus “proofs” (although the Riemann Hypothesis may be another contender.) This is well-known among publishers like arxiv.org and philsci-archive, which get plenty of crank submissions. These topics are generally treated with distrus…

Beyond the CPT theorem

…heorem or something like it? It is widely believe that the CPT may fail in generic extensions of quantum theory. 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.

Group Theory Of Your Spine

…ing Wigner to famously call mathematics in general “unreasonably effective.” (I recommend Octavio Bueno’s very informative analysis of this history.) 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…
