(The things I learn when listening to a baseball game... The context, unsurprisingly, is all of the rather specific days there are — several of them each day — and most of them seem rather pointless. For example, tomorrow is National Lollypop Day.)
That will make 11 wins in a row and a 31–4 record in our last 35 games!
Entering today, with our record of 65–29, we were more games above .500 than we have been any day since the last day of the 1974 season (so before I was born), when we won 102 games.
Also, based on current records (or perhaps All-Star break records?), 30 out of our first 36 games after the break are slated to be against teams that are under .500.
OMG OMG. Edward Teller tried a run as a television show host in 1955. How did I not know this? These photos are AMAZING. This is so bonkers. pic.twitter.com/lGsPPpQkbz— Alex Wellerstein (@wellerstein) July 19, 2017

This, by the way, was a very natural mistake to make. I hope that the song "Atomic" is in the film, at least.

Just about* every time that I got into trouble at school was an instance of rebelling against this (which was already the case when I was in elementary school and high school).
* Most other instances involved a radio and a baseball game.

Update: The Stanford obituary was written nicely. (Tip of the cap to Leslie Sheppard.)
Update: Here is Terry Tao's tribute.
Update (7/18/17): Here is the AMS's brief obituary, which includes links to some other tributes as well as prior articles.

Good luck with that one.

I'm pretty sure that one can also use a modification of the "diagonal argument" to prove that the set is uncountable. :)

"Mean-Field Approach to Evolving Spatial Networks, with an Application to Osteocyte Network Formation"
Title: Mean-Field Approach to Evolving Spatial Networks, with an Application to Osteocyte Network Formation
Authors: Jake P. Taylor-King, David Basanta, S. Jonathan Chapman, and Mason A. Porter
Abstract: We consider evolving networks in which each node can have various associated properties (a state) in addition to those that arise from network structure. For example, each node can have a spatial location and a velocity, or it can have some more abstract internal property that describes something like a social trait. Edges between nodes are created and destroyed, and new nodes enter the system.We introduce a "local state degree distribution" (LSDD) as the degree distribution at a particular point in state space. We then make a mean-field assumption and thereby derive an integro-partial differential equation that is satisfied by the LSDD. We perform numerical experiments and find good agreement between solutions of the integro-differential equation and the LSDD from stochastic simulations of the full model. To illustrate our theory, we apply it to a simple model for osteocyte network formation within bones, with a view to understanding changes that may take place during cancer. Our results suggest that increased rates of differentiation lead to higher densities of osteocytes, but with a smaller number of dendrites. To help provide biological context, we also include an introduction to osteocytes, the formation of osteocyte networks, and the role of osteocytes in bone metastasis.

This is quite the erratum from the 1983 edition of Bogoliubov and Shirkov's "Quantum Fields." (Shirkov did pass away last year.) pic.twitter.com/btMCHACu6I— Robert McNees (@mcnees) July 3, 2017
