Philip Hartman
Philip Hartman (May 16, 1915 – August 28, 2015) was an American mathematician at Johns Hopkins University working on differential equations who introduced the Hartman–Grobman theorem. He served as Chairman of the Mathematics Department at Johns Hopkins for several years. He has an Erdös number of 2.[6]

gollark: I prefer the set dictionaries.
gollark: ``` A language based on the idea of communism. There would be only one great editor (a wiki or similar) and all programmers would write only one big program that does everything. There would be only one datatype that fits everything, so everything belongs to one single class. Functional programming is clearly based on the idea of communism. It elevates functions (things that do the work) to first class citizens, and it is a utopian endeavor aimed at abolishing all states. It is seen as inefficient and unpopular, but always has die-hard defenders, mostly in academia. Besides, ML stands for Marxism-Leninism. Coincidence? I think not. It should be called Soviet Script and the one big program can be called the Universal Soviet Script Repository or USSR for short. And they put all the packages together in one place (Hackage). It already exists and is called 'Web'. It already exists and is called 'Emacs'. Emacs is the one great editor, and the one big program (Emacs can do almost anything). The language is Emacs Lisp, which is functional, and almost everything is a list (the one great datatype/class). Unfortunately```
gollark: It's pronounced Piephoon, by the way.
gollark: Owwww, my eyes.
gollark: I personally use LineageOS, microG and the Yalp play store thing.
