Ask HN: [Poll] How many materials science and engineering people are here?

Hello everyone,

I just wanted to get a quick assessment of what percentage of HN community represent people who work in the materials science and engineering (MSE) domain (both industry and academia). Please comment "MSE" (or, better yet, "MSE, {industry|academia|NL}"), if it's applicable to you (and "!MSE" otherwise). Feel free to upvote as well to improve this post's exposure. Thank you very much in advance.

P.S. "NL" above refers to national labs.
