I was thinking of that. My Ph.D. (now 40+ years ago) is from this
department:
https://www.brown.edu/academics/applied-mathematics/
(One of the few US universities then with a separately-identified Applied
Mathematics department.)
One of my freshman classes in 1971 was numerical methods with many hours in
front of an APL terminal.
Math is the hidden language of nature, I thought when I went there. The
separate Mathematics department then didn't have as cool of a building as
Applied Mathematics, a sort of gothic mansion.
