This is a really neat post, if you want to see Steve explain the accomplishments of the recently deceased mathematician Alexander Grothendieck. It would be pointless for me to try to convey the substance of the post; you should just read it if you are interested.
However, let me once again observe that Steve is the most religious atheist I have ever known. Here’s how he opens his post:
I never met Alexander Grothendieck. I was never in the same room with him. I never even saw him from a distance. But whenever I think about math — which is to say, pretty much every day — I feel him hovering over my shoulder. I’ve strived to read the mind of Grothendieck as others strive to read the mind of God.
Those who did know him tend to describe him as a man of indescribable charisma, with a Christ-like ability to inspire followers. I’ve heard it said that when Grothendieck walked into a room, you might have had no idea who he was or what he did, but you definitely knew you wanted to devote your life to him.
