The degree of irrationality of some people’s assertions is simply astonishing. Three weeks ago, I discussed Sabine Hossenfelder’s insane attack against an innocent promotional video for a future particle collider.

Why do you think that string topology is called string topology and not quantum graphity topology, among other choices?

Last revised on August 31, at Now, your humble correspondent doesn’t like to view these things as a rigorous mathematician and he doesn’t understand most of these things but he can still recognize that they often study the same structures with a different focus and motivation, with higher standards of rigor, with smaller or no attention to the physical relevance, and with a higher degree of generality than what is useful for physics.
