Garry Kasparov on Chess, Computers, and Grandmasters Using Computers

Original image

In what is nominally a book review, chess grandmaster (and lately, politician) Garry Kasparov discusses how computers have changed chess. Famously defeated by IBM's Deep Blue in 1997, Kasparov railed against computer chess in the 80's and 90's, but now he has some perspective on the matter, and shares his deep knowledge of the subject in The Chess Master and the Computer. This is a really interesting article for those interested in chess, computers, or other games (like poker) where computers are increasingly coming to the fore. Kasparov's discussion is nuanced, and he includes a detailed discussion of something I knew nothing about -- how high-level chess players are now ALSO using computers during some matches, and how that has changed young players. A snippet from the article:

There have been many unintended consequences, both positive and negative, of the rapid proliferation of powerful chess software. Kids love computers and take to them naturally, so it's no surprise that the same is true of the combination of chess and computers. With the introduction of super-powerful software it became possible for a youngster to have a top- level opponent at home instead of need ing a professional trainer from an early age. Countries with little by way of chess tradition and few available coaches can now produce prodigies. I am in fact coaching one of them this year, nineteen-year-old Magnus Carlsen, from Norway, where relatively little chess is played.

The heavy use of computer analysis has pushed the game itself in new directions. The machine doesn't care about style or patterns or hundreds of years of established theory. It counts up the values of the chess pieces, analyzes a few billion moves, and counts them up again. (A computer translates each piece and each positional factor into a value in order to reduce the game to numbers it can crunch.) It is entirely free of prejudice and doctrine and this has contributed to the development of players who are almost as free of dogma as the machines with which they train. ...

... In the pre-computer era, teenage grandmasters were rarities and almost always destined to play for the world championship. Bobby Fischer's 1958 record of attaining the grandmaster title at fifteen was broken only in 1991. It has been broken twenty times since then, with the current record holder, Ukrainian Sergey Karjakin, having claimed the highest title at the nearly absurd age of twelve in 2002. Now twenty, Karjakin is among the world's best, but like most of his modern wunderkind peers he's no Fischer, who stood out head and shoulders above his peers—and soon enough above the rest of the chess world as well.

Read the rest for an excellent overview of the history of computer chess, including plenty of personal anecdotes that I found fascinating.

Play a Game to Help Scientists Defeat a Cancer-Causing Toxin

If you're used to fighting virtual zombies or flying spaceships on your computer, a new series of games available on Foldit may sound a little unconventional. The object of the Aflatoxin Challenge is to rearrange protein structures and create new enzymes. But its impact on the real world could make it the most important game you've ever played: The scientists behind it hope it will lead to a new way to fight one of the most ruthless causes of liver cancer.

As Fast Company reports, the citizen science project is a collaboration between Mars, Inc. and U.C. Davis, the University of Washington, the Partnership for Aflatoxin Control in Africa, and Thermo Fisher Scientific. The team's online puzzles, which debuted on Foldit earlier this month, invite the public to create a new enzyme capable of finding and destroying carcinogens known as aflatoxins.

Aflatoxins form when certain fungi grow on crops like corn, nuts, and grains. Developing countries often don't have the resources to detect it in food, leaving around 4.5 billion people vulnerable to it. When people do eat food with high aflatoxin levels unknowingly, they can contract liver cancer. Roughly a quarter of all liver cancer cases around the world can be traced back to aflatoxin exposure.

The toxin's connection to agriculture is why the food giant Mars is so interested in fighting it. By working on a way to stop aflatoxins on a molecular level, the company could prevent its spread more efficiently than they would with less direct methods like planting drought-resistant crops or removing mold by hand.

The easiest way for scientists to eradicate an aflatoxin before it causes real harm is by making an enzyme that does the work for them. With the Aflatoxin Challenge, the hope is that by manipulating protein structures, online players will come up with an enzyme that attacks aflatoxins at a susceptible portion of their molecular structure called a lactone ring. Destroying the lactone ring makes aflatoxin much less toxic and essentially safe to eat.

The University of Washington launched Foldit in 2008. Since then, the online puzzle platform has been used to study a wide range of diseases including AIDS and Chikungunya. Everyone is welcome to contribute to the Foldit's new aflatoxin project for the next several weeks or so, after which scientists will synthesize genes based on the most impressive results to be used in future studies.

Every Laser-Cut 'Geode' Jigsaw Puzzle is One of a Kind

Nervous System

If you haven’t picked up a boxed jigsaw puzzle in a while, trust that they’ve undergone a serious transformation since your childhood. One of the most innovative companies in the category is Nervous System, a self-described “generative design studio” that composes computer programs to create puzzles based on patterns found in nature.

Their latest project, Geode, is a line of jigsaw puzzles modeled after agate stone. Like the rest of Nervous System’s puzzle inventory, it has an unusual and dynamic design; it's meant to mimic the band pattern of actual agate created by trapped gas in volcanic stone.

Several geode puzzles are shown

According to Nervous System’s site: “To create the organic shape of the pieces, we designed a system based the simulation of dendritic solidification, a crystal growth process similar to the formation of snowflakes that occurs in supercooled solutions of certain metallic alloys. By varying the parameter space, the system can produce a variety of cut styles. Each puzzle produced features its own unique landscape of interlocking shapes. No two are alike.”

Though lovely to look at, the puzzles utilize Nervous System's "Maze" piece-cutting method, which results in irregular and distorted shapes that may prove "fiendishly difficult" for some.

The 8.5-inch puzzles are made from plywood and feature 180 pieces. You can grab one for $60 at Nervous System’s online shop.
