I am at an international conference (ICIAM2019) about numerical methods and am surprised by the prevalence of applications directly relatable to arms research.
One award winner holds his talk about the mathematical problem of radar reconstruction/detection of moving objects, within his talk he describes the situation of a radar "platform" in 8km height using active radar detecting "moving subjects" at ground level, and he goes on about how magnificently tricky this problem is.
people are presenting methods to accurately resolve and simulate shockwaves, and a quick google search reveals that they are working on "inertial confinement fusion".
at after-conference dinner I sat next to people doing numerics in Los Alamos.
I am doing my phd in applied math and numerical methods, and to be honest, I did not anticipate that the people receiving awards and are put on the large stages are doing arms research. I also noticed that the audience, which is presumably smarter than me, is applauding this work.
I am wondering whether or not I would want to be part of this community, and if it is possible to build a career in applied math without directly or indirectly contributing to arms research. Is this something that is shrugged of? I am at a very early stage and would be very grateful for advice from the more experienced folks.
