The Best Thing Since Something Other Than Sliced Bread?
But before there was sliced bread, did people use an expression like this? And what was used in the expression instead of sliced bread?
(I am obviously far from the only person to wonder about something like this. See this page and various other Web pages.)
What is Each Country Number 1 in?
My favorite one (which I have noticed so far) is Sweden, which is the "best" at pop music.

"The Physics of Spreading Processes in Multilayer Networks"
Title: The Physics of Spreading Processes in Multilayer Networks
Authors: Manlio De Domenico, Clara Granell, Mason A. Porter, and Alex Arenas
Abstract: Despite the success of traditional network analysis, standard networks provide a limited representation of complex systems, which often include di erent types of relationships (or 'multiplexity') between their components. Such structural complexity has a significant e ect on both dynamics and function. Throwing away or aggregating available structural information can generate misleading results and be a major obstacle towards attempts to understand complex systems. The recent multilayer approach for modelling networked systems explicitly allows the incorporation of multiplexity and other features of realistic systems. It allows one to couple di erent structural relationships by encoding them in a convenient mathematical object. It also allows one to couple di erent dynamical processes on top of such interconnected structures. The resulting framework plays a crucial role in helping to achieve a thorough, accurate understanding of complex systems. The study of multilayer networks has also revealed new physical phenomena that remain hidden when using ordinary graphs, the traditional network representation. Here we survey progress towards attaining a deeper understanding of spreading processes on multilayer networks, and we highlight some of the physical phenomena related to spreading processes that emerge from multilayer structure.

One More Turn (Again): Civilization VI
I am playing as Gorgo (Greece, Spartans). My second city is Rhodes, though when my slinger covered the "RH", it looked like "ODES" rather than "RHODES". I wanted to change the city name to "ODEs", but I couldn't figure out how to do it. (I have also been having some trouble picking up some of the commands for simple things.) Given the set of leaders and civs, clearly there are now going to be multiple leaders within a given civ. Two examples of this were available so far, but given these examples and other descriptions (e.g., of the Americans), there will be more. Given the "Selfie" achievement, one's opponents can also include the same leader.
Thus far, I have picked up the "Escort Service" achievement (unsurprisingly). Two achievements that I want to acquire are "Luftballons" and "Missed That Day in History Class" — the former because it's a gratuitous Nena reference (with an associated nice combination of things to get it) and the latter simply because it's highly amusing. Other cultural references in the achievement list so far include the B-52's song "Roam" and the Lego movie.
I'm not yet sure what I think about the Civ VI way of doing things. Clearly I'll need to play more and find out. (It will probably also be beneficial to do a multiplayer game to accelerate learning, but I don't know if the Mac and Windows are ready to interface with each other yet.) I also need to get work done, and I have a very large backlog of papers to finish and other things with hard deadlines to do. And I have a couple of novels I really want to read, and the World Series starts tomorrow. :)
Update (10/27/16): Also, I really hope that Civ VI is still making fun of Dan Quayle. :) This is having a significant effect on his legacy in history. If not for Civ, many people would never have heard of him and he'd be all but forgotten by many others by now. Civ may actually help give him a more "permanent" legacy!
Update (11/06/16): I won a Culture Victory and achieved the level of Emperor Nero. I can also confirm that Civ is still making fun of Dan Quayle (25 years later...), which is again the lowest level of achievement in the game. Eventually, people playing this series of games will probably wonder if he was ever a real person. :)

Wait 'Til Next Year (Again)
It's been 28 years since we won, so I have developed some patience over the years.
In the NLCS, the Dodgers were outplayed by a substantial margin by a very good team that was the favorite from the beginning for good reason. Good luck to the Cubs in the World Series. Their fans have been waiting a lot longer than I have. (And the fans' reaction I see on tv right now is far more emotional than one typically sees from World-Series-bound teams, and also for good reason.)
The World Series this year is quite an interesting matchup: the Cubs versus the Indians, and it's been a very long time since either of them won it all.
Hopefully it will be our year in 2017.
Update: Javier Baez and Jon Lester were named co-MVPs of the NLCS.
Update 2: Also, for what it's worth (and even though Charlie Sheen is a nutjob), I would actually like to see Wild Thing throw out the first pitch. And then Bob Uecker could announce that first pitch!

Off to the NLCS!!!!
And with one out and men on first and second, Clayton Kershaw came into the game for his first relief appearance since 2009. I had noticed Kershaw tossing a ball a bit in the dugout in the middle of the game and figured he would be available for something like this.) Kershaw started off by getting last year's nemesis Daniel Murphy to pop up. He then got the third and final out to beat the Nationals and win the NLDS.
And so we're off to the NLCS!!!! (And we're going to be facing a very, very tough Cubs team. The Cubs are a juggernaut, and we are most certainly the underdogs.)
Today was the longest 9-inning postseason game in Major League Baseball history. This series saw a Major League record for number of pitching changes in a Division Series, and it also saw a Major League record number of batters hit in a postseason series. (It was a really tough series. The Nationals are a strong team.)
Regardless of how things turned out, we had to go with our best. (None of this Showalter don't-use-your-best-pitcher nonsense from their do-or-die game against the Blue Jays.)
Go Dodgers!!

Book Recommendation: The Bone Season
Especially highly recommend if you like dystopian fantasy (the book scores very high in world building, which tends to be a big win for me), and especially highly recommended if you've spent time in Oxford.
(So far, most of the book takes place in dystopian Oxford—including dystopian High Table, dystopian Magdalen deer park, dystopian tutorial, etc.)

United States Ice 'Cube' Tray: Made in China
In addition to ignoring Alaska and Hawaii, there was a bit of coarse-graining done with the continental states. Who needs all 50 states anyway?
And the label ‘cube’ (on the front; not pictured) doesn’t quite work either.
Also: “Made in China”
(But at least I can now have some ice while I wait to have access to my Screamer tray again.)
My Snark has Appeared on a Buzzfeed List of Quotes in Scientific Publications
This list includes some classics. I am pretty sure that the list was scoured in large part (almost completely?) from the tumblr Easter Eggs in Scientific Papers, and I did point out my entry (#11) on this list to him, and he then posted it on the Easter Eggs tumblr.
And I have many more examples where #11 came from. (Here is the paper in question.)

2016 Physics Nobel Prize for Topological States of Matter
So exciting!
(This was a big subject that I remember often being discussed in Caltech's condensed-matter theory group when I was part of it. I am sure that it still is.)
Theoretical condensed-matter physics, statistical mechanics, and topology are the big winners. That's just about a home-team victory this year!
(My preference still would have been chaos being recognized, but I am very happy with this year's result. I also want Michael Berry to get a richly-deserved award for geometric phases.)
Update (10/05/16): Here is an editorial about the (very severe) lack of women who have won the Nobel Prize in Physics. And a couple of weeks ago, a top contender Deborah Jin died way too young, so among other tragedies, now she can't get the Nobel that her work richly merits.

Baseball Goodbyes
Of course the one I care about the most (by many orders of magnitude) is that today was Dodger great Vin Scully's last broadcast. As I write this, the article to which I linked is very terse, but I watched the game (of course!), and the Giants organization was very classy indeed in the way they honored Vin—including a big deal during the 7th inning stretch, giving the fans goodbye placards for Vin, and putting up a permanent placard in the visiting broadcast booth commemorating his final game. (I'm sure I'll find some links to add later, but in the meantime, here is the box score for the game.) This was a very nice complement to Vin Scully Day at Dodger stadium for his final home game. Vin was typically low key, though of course this wasn't just a normal game. In an earlier blog entry, I compiled a short list of some tributes to (and vignettes about) Vin Scully. Today was in fact 80 years to the day that Vin Scully fell in love with Baseball (in a story that he's been telling for the last couple weeks). Vin has been the voice of the Dodgers for 67 years and is the most beloved Dodger of all.
I am now 40 years old, I have listened to Vin Scully (the best broadcaster of all time!) call baseball games since I was a little kid—maybe the first time when I was 3 years old?—and I fell asleep to his sound on the radio back in the day (and, given my time on the U.S. east coast and of course my 9 years in Oxford), and I listened to Vin's voice sooth me to sleep from my computer in more recent years. Every year, I knew and felt that a new Baseball season started when I first heard Vin's voice announcing that it's time for Dodger baseball and wishing me a very pleasant good evening or afternoon (wherever I may be). That's how Vin signed off today. Thank you for everything!
Meanwhile, in Boston, there was a tribute to David Ortiz (whose number the Red Sox will retire next year, and this marks the first time ever that the Red Sox are doing that for a player who is not yet in the Hall of Fame), though he'll still be playing for them in the upcoming postseason.
The Yankees said goodbye to Mark Teixeira.
We also said goodbye to Turner Field in Atlanta.
Update: Here is an article giving some details about today's very classy tribute to Vin Scully from the Giants.
Update: Here is Vin's final message to Dodger fans. It was special watching today's game.
Update: Ryan Howard played what is likely his final game with the Phillies, although it looks like he's going to try to latch on with another team. (I write "probably" because, if Howard's career persists, I could imagine Philadelphia bringing him back as an inexpensive backup player a couple of years down the line.)
Update (10/04/16): Another very good announcer who retired at the end of the regular season on Sunday is Dick Enberg.
