What I’m Doing Now

This is Michael Hartl’s /now page, per the /now page movement by Derek Sivers (@nownownow). It’s a page with information about what I’m up to now. Join my mailing list and follow me on 𝕏 to get more frequent updates.

Since the acquisition of my company in 2022 and finishing my final tutorial project in 2023, I have been focusing on reconnecting with my roots in theoretical physics. My current project involves a systematic course of study in mathematics. After some experimentation, I’ve determined that focusing on two primary slots works best for me; here are my current ones:

  1. Linear Algebra at Math Academy

  2. Understanding Analysis by Stephen Abbott (partial solutions)

See my blog posts for more, especially Math Learning Project and Resources for Math Learning (Intro to Math).

I am also active as an advisor to several startups and other projects (especially those related to AI, Urbit, and Bitcoin), though I am not currently seeking new investments. I live in Los Angeles, CA (Santa Monica near Venice Beach).
