Jason Rosenhouse received his PhD in mathematics from Dartmouth College in 2000. He subsequently spent three years as a post-doc at Kansas State University. Currently he is Associate Professor of Mathematics at James Madison University in Harrisonburg, VA. This blog is about science, religion, math, politics and chess, roughly in that order.
Folks, I'm done.
A recent story in the news involves the decision by FIDE, the world chess federation, to hold the Women's World Championship in Iran. That's a bit awkward, since Iran imposes certain religion-inspired dress requirements on women. This has led some players, most notably the…
I've just posted the new Problem of the Week, along with an official solution to last week's problem. But this one will have to hold you for a while, since I'm taking next week off.
Better late than never! A small technical SNAFU yesterday interfered with the well-oiled machine that is Problem of the Week. But now we're back on track! The fourth problem has now been posted. The official solution to last week's problem will be up by tomorrow.
Do you remember those commercials, from a few years back, for Excedrin headache medicine? There was a whole series of them. In each, some very normal-looking and totally relatable person would talk straight to the camera, explaining that he or she suffered from terrible headaches and had tried…
Kevin Drum has a short post noting that Trump has taught other Republican politicians how to lie more brazenly. Politicians have never been noted for their honesty, but we are seeing something new this time around. It is very aggravating that Trump simply makes it up as he goes along, while…
Just want to poke my head up to mention that I have posted a new POTW for you. You get three for the price of one this week. The official problem is pretty straightforward, I think, so I gave you two bonus problems just for fun. Enjoy!
The second Problem of the Week has now been posted. It's a harder version of last week's problem, but perhaps it is good for a bit of amusement. By its nature, it might be a bit hard to describe the solution in a comment, but have a look anyway.
On Morning Joe today, Mike Barnicle asked Libertarian Presidential candidate Gary Johnson what he would do about Aleppo. Johnson's reply was, “What is Aleppo?”
We're done here. Johnson should withdraw from the race, go home, and never show his face in public again.
When did running for…
I realize that I never finished the story of how I achieved the exalted rank of expert at chess. Suffice it to say that I played two more games beyond the ones I have already reported on. Both were against 1900 rated players and both were rather dissatisfying draws. In the first I had the black…
In a technical, legalistic sense, the semester started last week. But as far as I'm concerned, the semester doesn't really begin until Problem of the Week returns!
Our theme for this semester: Clock Problems.
That's not code for modular arithmetic or anything. I mean it literally. Every problem…
Classes start on Monday. I knew that intellectually, of course, but I had it brought home to me a few days ago when I innocently drove onto the campus, only to find a traffic jam and crossing guards directing the cars. Students were moving into the dorms, you see.
Higher education is beset with…
The AP is breathlessly reporting that 85 out of 154 people coming from private interests (as opposed to governmental functionaries) who met with Hillary Clinton when she was Secretary of State were also donors to the Clinton Foundation. The headline: “Many Donors To Clinton Foundation Met With Her…
I have previously mentioned that the Washington International was the best run and most enjoyable tournament I have ever played in. One reason was the fact that all equipment, sets and clocks, was provided. And not just any equipment! Look at these beautiful wooden chess sets we were given to…
My reward for winning in Round One was to be paired up for Round Two. My opponent was the top seed in the section, with a rating of 2179. I received my second white in a row. Here's what happened.
I started with my usual king pawn, and he replied with the Modern Defense. This was a fine how…
I know I haven't been around for a while. Sorry about that. A bit of the summer doldrums I guess. But now I have big news to report, for the handful of people who like my chess posts.
As big a chess fan as I am, I have been mostly retired from tournament play for a number of years. Sure, I…
I had a book deadline this past Friday. Making that deadline, which I did, thank you very much, has been all consuming for the past two weeks. And now I am on the road until July 16. So, the blog darkness will persist for a while.
Sorry about that...
In April I gave a presentation on the Monty Hall problem, at the Museum of Mathematics in New York. That talk has now appeared on YouTube. Here it is:
The talk is about fifty minutes, with twenty minutes of questions afterwards. There's also a short introduction by Jason Rosenfeld, who is a…
Back to chess! My quest for the expert title continued at the Continental Class Championship in Herndon, Virginia this weekend. Full report to come.
While I was there, I played in the big Saturday night blitz tournament. Blitz chess is rated separately from regular chess, and with good reason!…
Edward Feser thinks we atheists have overlooked a few things:
The mentality is summed up perfectly in the notorious “Atheist Bus Campaign” of 2009 and its preposterous slogan: “There's probably no god. Now stop worrying and enjoy your life.” As if atheism promised only sweetness and light. As…
The latest issue of The Problemist showed up in my mailbox recently. It contained a very nice selfmate that I've chosen for this week's problem. This is one of those really clever ideas that I think you can only show once. The problem was composed Alexei Oganesyan, and was awarded this year. It…
Speaking of the intellectual collapse of ID, its other major blog, the Discovery Institute's “Evolution News and Views” also seems to have fallen on hard times. How else to explain the presence of this article, by Steve Laufmann?
Laufmann addresses the question, “Is Intelligent Design Science?”…
At various times over the last few years I have declared ID to be dead. One of my reasons for saying that is the complete intellectual collapse of Uncommon Descent (UD).
When William Dembski started the blog, it was intended as an outpost for serious commentary on intelligent design and related…
The inevitable has now occurred. Barring something earth-shattering, Hillary Clinton will be the Democratic nominee for President. She is the first woman to become the nominee of a major political party. In fact, she is the first woman even to be a serious candidate for President.
In her…
Time for the big finale. The Monday morning game. Since I had already requested a bye for the final round, this was my last chance to make a respectable result. Here's how it went down.
I was playing black. My opponent sported a rating of 1983. But he also had a formidable Russian name, and I…
After my win in round two I was excited for round three. My opponent sported a 1952 rating, and he had white. He opened with 1. e4.
Now, over the years I've tried most of the major defenses to e4. I was an aficionado of the Dragon Sicilian for a while, until I noticed I kept getting mated on h7…
No Sunday Chess Problem this week, but I do have a good excuse. It's because I just spent the past few days participating in the Cherry Blossom Classic chess tournament. Enough with made-up chess positions! Sometimes it's good to experience the real thing.
For about ten years now I've been…
I think in the end Hillary will win in November, but I become less confident about that by the day.
Donald Trump's latest is to bring up Vince Foster. Those of us who remember the nineties will recall this as one of the many fake scandals the right-wing noise machine just invented from whole…
I may not blog as much as I used to, but I do still sometimes put myself out there. I just did a podcast with Jim Stein, posted over at the New Books Network. Jim is professor of mathematics at California State University at Long Beach.
The conversation was about the book I coedited with Jennifer…
Yes, I know it's Monday. But it's still Sunday Chess Problem. Deal with it.
One more from the files of Milan Vukcevich for you. This problem was published in 1994 and calls for selfmate in five:
Recall that in a selfmate, white plays first and tries to force black to give mate in no more than…
I was going to write a real barn burner of a post about the big election, but then I came across this:
Folks, sometimes you just have to focus on the good things in life.
