Paper 2 accepted… paper 3 referee report in (minimal changes!)…research ideas flowing… Copenhagen trip in 2 days (for math AND for leisure with girlfriend for 4 year anniversary!)… San Juan conference in 12 days… survey article due date extension… I am feeling very hashtag blessed

One could argue that a large component behind the way I am today is due to 12 year old me watching Ben Wyatt in Parks and Rec saying “I gotta keep my Hüsker Dü records in mint condish!”

Probably the best thing about being an academic is the days I get to spend at home doing research, blasting fusion-era Miles Davis, hanging out with these goobers

There’s a past version of myself that would argue to the death that “Room on Fire” was a better album than “Is This It?” and I would now argue to the death with my past self that the opposite is true

I’m so broken by chromatic homotopy theory… I was just in a seminar about smooth structures on spheres (very real tangible stuff) and there was a brief connection with periodic elements in stable homotopy (very fake made up stuff) and the only questions I had were about vn-periodicity
