Oh don't be snarky, I mean for goodness sake, the subheader makes it more than clear what is intended: > A former graduate student reflects on how Isadore Singer, who died on February 11, brought together mathematicians, physicists and anyone else interested in the deeper connections between diverse fields. Having studied physics and knowing plenty of mathematicians I can safely say that none of us would have been confused as to what this is referring to, even without that subtitle. Yes, all physics uses maths. That's not what this title is referring to. It's referring to actually being a mathematician or physicist in the last century - of being part of that professional community and the research done within those communities. Because the main interests of mathematicians and physicists have diverged a lot and having them work together is not at all a given these days.
