There was a Memorial Service for Paul Samuelson last weekend.  A video of the service and texts of speeches are available and they are quite interesting.  Ricardo Caballero’s speech has a lovely passage where he describes a faculty lunch on a snowy day.  To a small group of colleagues, Samuelson held forth on a thesis of Alberto Calderon,  John Nash’s contemporary at M.I.T.   Caballero says:

“This episode left such an impression on me that I decided to take the afternoon off to savor the moment. (And afternoons off are not my thing, as many of you
know…)   I drove home in complete awe. The silence that only snow can produce, served to exacerbate the surreal feeling I was experiencing. Much like what one feels when visiting the Basilica di Santa Croce in Florence, where names such as Michelangelo, Galileo, and Machiavelli are buried: Sheer and pure admiration for a great mind.”
