"Dirac's argument for electric charge quantization is not to be taken lightly because it is the first "topological conservation law" uncovered in Abelian gauge theory. Since Dirac's two papers on the magnetic monopole were published, other potential physical examples of "topological conservation laws" have been identified in non-Abelian gauge theories which have revealed the rich topological structure of QCD ... Moreover, with regard to Dirac's ECQ argument, it is likely that — within the framework of the standard model — ECQ is well explained by the chiral gauge anomaly-free constraints, which, to some extent, contain topological information ..."

"Step back in time; look closely at the child in the very arms of his mother; see the external world reflected for the first time in the yet unclear mirror of his understanding; study the first example…"

"The choice before human beings, is not, as a rule, between good and evil but between two evils. You can let the Nazis rule the world: that is evil; or you can overthrow them by war, which is also evil…"

"The trouble I have with astrophysics or quantum mechanics is the same problem I have with philosophy; which is: initially it is mind blowing, then it is fascinating, then it is disturbing, then it is …"

"When Hume and Adam Smith prophesied that a little increase of national debt beyond the then amount of it, would probably occasion bankruptcy; the main cause of their error was the natural one, of not …"
