Reading List Update

I posted a reading list a few months ago, and I thought I'd post an update.

Currently Reading:

Anton, Dale Eisler
This is my uncle's third book and first novel. It's a fictionalized account of the events surrounding my grandmother's family during the Bolshevik Revolution after the first world war - Anton, the main character, is based on my great-uncle Tony. The full synopsis and other information is given on the book's website.

I'm a couple chapters in, and enjoying the writing so far. It's a bit tough for me to read, since it's very personal for me, and there are some really tragic events that happen in the story. It's going to be an interesting experience to read this.

The Princeton Companion to Mathematics
I've read a few sections here and there, which have been uniformly excellent. It's quite slow going, though, as the topics require full attention and can't really be read casually.

The Dark Tower: The Gunslinger Born
I've only read the first chapter of this, but I'm enjoying it so far.

Recently Read:

Logicomix, Apostolos Doxiadis & Christos Papadimitriou
This is a book that I almost can't believe exists - it's a graphic novel about the life of Bertrand Russell and his involvement in the development of the modern philosophy of logic and mathematics. It's difficult to describe, so I'll just link to the Amazon page.

Under the Dome, Stephen King
I thought this was one of the better recent King books, and was a quick read for a thousand-page book. It was nothing earth-shattering, but I quite enjoyed it. 4/5.

The Book of Basketball, Bill Simmons
I generally like Bill's writing style and share his sense of humour, and this book was no exception. On the other hand, I'm only a casual basketball fan, so the topic itself wasn't great for me. I'd say 5/5 for writing and 3/5 for subject matter, so I guess 4/5 overall.

In the "To Read" Pile:

Shalimar the Clown, Salman Rushdie
Godel's Proof, Ernest Nagel & James Newman
A Mathematical Nature Walk, John Adam

Chess Query Language

It's amazing how many tools are available on the web for seemingly obscure tasks. Recently, a friend of mine was writing a short story, and he needed an answer to this question: In high-level chess games, how often do the different pieces survive through the game without being captured (ignoring kings)? In the context of this question, each of the 30 starting pieces is treated as distinct; we want to know how often the pawn that starts on the a2 square survives, how often the b2-pawn survives, etc., rather than how often general pawns survive.

I think this qualifies as an obscure question. It seems simple enough to answer in principle - just get a database of games, and write something to play through each game, tracking which pieces survive. Simple enough, but a fair bit of work. Luckily there's a tool that will do this type of thing: Chess Query Language.

CQL is quite powerful, and it's pretty straightforward to set up a CQL query. For example, to answer the above question about survival rates, I started by creating a query to see how often the white queen's rook survives:

:forany Rook R
(:position :initial $Rook[a1])
(:position :terminal $Rook[a-h1-8])

That's it. The first line creates a Rook piece designator; the second and third lines specify positions that have to exist in a game for the game to match the query. Thus the query will match any game where a rook is on the a1 square in the initial game position, and that same rook is somewhere on the board in the terminal game position.

This query took about 45 minutes to run through a database of about 2.5 million games, and found that this rook survived in about 1.4 million of them. I just had this repeat for all pieces and pawns to generate the final answer.

So, I can advise that if you're ever involved in a Harry Potter-style human chess game, you should volunteer to be one of the wing pawns. Don't allow yourself to play as a knight, whatever you do.

A Few More

Here are a few more photos of Owen.

All ready for the opening ceremonies tonight.

Owen at 9 Months

Owen is over 9 months old now, so here are a few new photos.

It took Owen less than a year to abandon daddy's Chargers. Smart kid.

Reading List

I received a few new books over the Christmas holidays. They total somewhere in the neighbourhood of 3,500 pages, so I should be finished reading them all roughly around the end of time. Here they are briefly, and hopefully I'll post some comments as I finish each of them. Don't hold your breath, though.

The Princeton Companion to Mathematics
This is a wonderful thousand-page book that would seem to have an incredibly narrow appeal. It's essentially a survey of current thinking across all mathematical disciplines, written to be as accessible as possible. The original goal for the book was that it could be handled by anyone with high school-level math, but the authors weren't able to meet this for all sections. I find this incredibly interesting, and pretty much everyone else I know would not find it interesting at all :).

Under the Dome, Stephen King
I'm a reasonably big fan of King, although I haven't read some of his more recent stuff. This one has been getting reviews in the range of good to great, and drawing comparisons to The Stand, which is a favourite of mine.

The Book of Basketball, Bill Simmons
Bill Simmons writes for ESPN; he's also known as The Sports Guy. This book is essentially just all of his opinions about basketball, including a few hundred pages ranking the best players of all time.

The Dark Tower: The Gunslinger Born
Stephen King wrote a seven-novel series called The Dark Tower over a period of about 30 years. Recently, Marvel has been publishing comics in the Dark Tower universe. This book is a collection of the first few issues.

A Mathematical Nature Walk, John Adam
I hadn't heard of this one prior to receiving it for Christmas, but it looks to be the kind of thing I like.

Close But No Cigar

A friend of mine, who cheers for the Pittsburgh Steelers, has been talking about how close their losses have been this year. The Steelers finished 9-7, but the 7 losses were by a total of only 28 points, so a couple plays one way or the other could have produced a very different result. I'm quite familiar with this line of thinking, since my team is the Chargers, and last year they lost 8 games by a total of only 34 points (including a 1-point loss on a terrible blown call in a game I drove 1000 miles to see. But I digress.) I have my trusty database, so I thought I'd take a look at how these two seasons stack up historically. The following items all consider the years from 1978 through 2008.

• Among all teams that finished at 9-7, the 2009 Steelers' total margin of defeat (28) was the lowest. The next closest were the 1993 Broncos (30) and the 2002 Saints (35).
• The 2009 Steelers' average margin of defeat (4.0) is the lowest among all teams that lost 7 or more games.
• Among all teams that finished at 8-8, the 2008 Chargers' total margin of defeat (34) is tied for the lowest with the 1999 Raiders.
• The 2008 Chargers' average margin of defeat (4.25) is the lowest among all teams that lost 8 or more games. The 2009 Steelers are the only team with 7 losses to have a lower average margin of defeat.

It looks like these two seasons were in fact quite unusual. Here are a few other interesting facts I came across while tabulating these results.

• The 16-0 2007 Patriots are a bit of a special case, but you might say that they hold the record for smallest average margin of defeat, at zero.
• The 1983 Redskins finished 14-2, and their two losses were by one point each.
• The next best average margin of defeat (2.33) was by the 2000 Titans, who finished 13-3 and whose losses were by a total of 7 points.
• The team with the worst average margin of defeat (24.7) was the 1989 Steelers. They actually made the playoffs at 9-7 (unlike this year's Steelers), but had several huge losses, including a 51-0 game against Cleveland. In the playoffs, the Steelers won their first game, and then lost to the Broncos... by 1.
