In separate deals, we also traded for left-handed relief pitchers Tony Watson of the Pirates and Tony Cingrani of the Reds.

This team is so amazing.
We now have an astounding 74–31 record (after our 8th win in a row, and recently we had 10-game and 11-game winning streaks).
We also now have a 14-game lead!
Next stop, Cooperstown! And it will be on the first ballot.
Beltré has been appreciated more in recent years as his counting numbers approach 'magic' milestones, but I still don't think most people truly appreciate just how excellent his career has been. I can't remember who wrote this — was it 538.com? — but I recently saw an estimate that put him in the top-5 third basemen of all time.
There is also a discussion at 538.com about future members of the 3000-hit club. The next member will be Albert Pujols, who will become the second person from the Dominican Republic (Beltré is the first) in the 3000-hit club. I believe that the next person after that will be Miguel Cabrera and then Robinson Canó. (Here are the active leaders in career hits.)
Update: Here's a new article in 538.com about Beltré's greatness as both an offensive player and defensive player.

P.S. The video for "Take on Me" is the best music video of all time! And this is one of the best songs all time — definitely in my top 5.
It's too bad that he won't continue pursuing both careers, but I have to say that I feel warm and fuzzy about passion for mathematics being such an important facet of his decision. (And his publication record for somebody at his career stage is very impressive even before considering the fact that he's simultaneously been playing pro football, which then makes it astounding.)
"I think it hurt my ability to think well mathematically," Urschel said. "It took me about three weeks before I was football-ready. It took me a little bit longer before my high-level visualizations ability came back."

You can see from this data analysis that math professors appear to be the least boring among all professors (yay!) and there are some expected (and perhaps more surprising) gender gaps (boo!) in the reviews.

(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.

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.

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.
