|content=One of the world’s greatest men has died. Most of you will have no idea who this is. I just don’t know how to bridge that gap yet to tell you what he did.
 
I was very close with his top collaborator. They were the [[Jim Watson|Watson]] and [[Francis Crick|Crick]] of mathematics to me. They rewrote my whole life.

|content=There is a little known stone wall on Long Island. While flawed, it is a gift to all mankind that should be a pilgrimage site, as an understanding of the contents is nesessary to understand our world. Think of it as transcendent graffiti. Atiyah‘s spray-paint is everywhere here.

|content=Imagine watery planets with holes and twists. Knotted donut planets  called base spaces. Crazy oceans called “Vector bundles” and “Principal bundles”.
 
He told us about how the twists and holes determine what waves must live on them and which cannot.

|content=I completely agree with your assessment of the magnitude of the world's loss here.  But who, in your view, was Atiyah's "top collaborator"? Bott, perhaps? Singer? Someone else? He shared credit with a large number of co-workers in his published work. (I'd vote for Bott, myself.)

|content=@MathPrinceps I knew [[Raoul Bott|Bott]] and [[Isadore Singer|Singer]] very well, but it was still not even close to me. I won’t say more here just now. You will also notice that Bott and Singer never collaborated despite being one zip code away from each other in Massachusetts Ave in Cambridge MA. Towering giants all.

|content=Are you anywhere near SF? I gotta hear your argument for Atiyah [[Raoul Bott|Bott]]. The main flaw on that wall IMO is the absence of [[Raoul Bott|Bott Periodicity]]. Other issues: Tits Freudenthal, the main Elliptic Deformation Complexes,  Hopf Fibration, etc..
 
But Bott Periodicity is beyond mind blowing.

|content=Yes, I reside in Mountain View, and get up to SF with some frequency. And I don't mean to make an argument for Atiyah-Bott, exactly; it's more of a feeling, born mostly of personal observation, that Atiyah-Bott had a much deeper aesthetic affinity than did Atiyah-Singer (say.)

|content=Wow. Did you guys ever talk shop? I have to admit I didn’t always get the most out of him 1 on 1. [[Isadore Singer|Singer]] and [[Raoul Bott|Bott]] were much clearer. [[Michael Atiyah|Atiyah]] and [[Ed Witten|Witten]] tended to tell you something related to whatever you asked but often not in a dialogue. More like a juke box of answers.

|content=@anisomorphism @Javlaskitstovel Sure it starts with [[Raoul Bott|Bott]] & Tu. With a little May. Before you know it? You’re. hitting the harder stuff. Hartshorne leads to EGA & SGA. Next? They find you in a gutter, begging to do even just a little of Jackson’s E&M to make the withdrawal symptoms go away.
Even for a moment
