I have recently been quite shocked to learn of the blog of an accomplished string theorist, which includes a lot of personal invective against physicists he disagrees with, as well as a lot of non-physics-related posts on politics from a right-wing perspective.
This is not the only example of which I am aware. There are some books that try to engage a mass audience in a foundational debate about physics in which a mainstream research program (string theory) is claimed to be fundamentally misguided. I have heard several anecdotes from acquaintances more along the lines of personal invectives, including one that included denunciations in social media and an editorial in Forbes magazine.
I am a mathematician, and it seems like such a culture of polemics is absent from my field. So I wonder: Is there something different about physics in this respect? Or have I just been lucky enough to avoid this side of the math community?
