I remember it being an issue in the McCain campaign but not with Trump. Anyway, it's not a young age but if it's only a discussion point for president of the whole country for presiding over the AMS it shouldn't be surprising at all.
The title of the article is somewhat strange in that it sounds like Mathematics doesn't have many real world applications. On the other hand I believe that the title of the article is very effective for people to share it or even as an attention grabber.
Well, a lot of people also believe that most modern mathematics is more abstract theory and rarely applied outside of its own field. Her work seems very closely tied to physics. So I don't think explicitly mentioning that she did applied maths is bad, especially for lay people
The article has a lot of good info in it. There is really more here than just the fact that someone died. I had never heard of her before, but the article was an interesting read due to the content of her work, basically.
