As you know I’m a fan of “applied pure math.” You can be an applied mathematician and not do PDEs or numerical analysis now! And to reflect this new reality, there’s a new journal, SIAM Journal on Applied Algebra and Geometry (SIAGA). They’re accepting submissions starting March 23; I actually have a little something that might be finished by then that would be perfect!

There are a bunch of cool pictures on the SIAGA flyer: UC-Berkeley grad student Anna Seigal is explaining them on her blog, one by one. The first entry depicts the algebraic variety you encounter when you try to find a point minimizing the summed distances to k other points in the plane. Handsome!

Ingrid Daubechies started her excellent colloquium talk here by (my interpretation) rejecting the idea that “applied math” is a single field of mathematics on par with group theory or PDE. Instead, we should think of analysis and applied analysis, PDE and applied PDE, group theory and applied group theory, number theory and applied number theory and so on. I found this perspective very compelling.
