           The other day I noticed something very cool: the most important equation describing particles in physics is basically the same as the most important equation describing risk in finance - with one crucial difference. Behold: the Schrödinger equation in quantum mechanics, and the

             I've just written about my very intense relationship with my father and how running helped me both connect with him and avoid becoming him. It's also my first article ever for @TheAtlantic . My dad wrote for the magazine in 1967, and i t seems fitting that the first piece

             Most consequential fun I ever had reading 906 pages. @JoshuaKushner, you're a legend, and thanks for always making everyone around you so much better

            @JoshuaKushner I don't know what it says about me that when I looked at this chart I forgot to add that my son Noah was born in late August 2012 (though I would say a founder pro-tip is to have a child when you start your company - no better way to remind you that other things matter)

             How a company starts: mine were never a straight line. I have some data: since 2012, I've been tracking everything I do to the minute. So I went back and looked what % of time went into Oscar. Coffee with @JoshuaKushner with the idea in March, started reading about health

             Sometimes the Bible is really oddly specific. Here, some practical & possibly misogynist marriage advice: "It is better to dwell in a corner of the housetop, than with a brawling woman in a wide house." (Proverbs 21:9)

             Mark on life and @OscarHealth, a must-see! 
           I’ve never heard a life story like this. Mark enduring insane hardship with his son, and then decades of extreme pain, but as he describes, the pain so impacts his brain that he also becomes a sort of business terminator during this period of pain. I’m not sure how he survived

             In 1984, IBM became one of the first large employers to adopt 401(k)s. It became a bellwether for the individualization of stock ownership - with a pretty straight line from there to ETFs, commission-free trading and eventually even r/wallstreetbets. Gradually, then suddenly.
