 Processing Power to Chess Rating Ratio

50 here is what the Deep Thought team wrote about the relationship between search depth and chess strength in a 1989 article: The ascent of the brute-force chess machines back in the late 1970s made one thing crystal clear: there is a strong causal relationship between the search speed of a chess machine and its playing strength. In fact, it appeared from machine self-test games that every time a machine searches one extra ply, its rating increases by about 200-250 rating points. Since each...

 Entropy in our Everyday Lives: Active Stability

Because things naturally move to disorder over time, we can position ourselves to create stability. There are two types of stability: active and passive. Consider a ship, which, if designed well, should be able to sail through a storm without intervention. This is passive stability. A fighter jet, in contrast, requires active stability. The plane can’t fly for more than a few seconds without having to adjust its wings. This adjustment happens so fast that it’s controlled by software. Ther...

Metagaming refers to the relationship between the game and outside elements, including everything from player attitudes and play styles to social reputations and social contexts in which the game is played. Post-game locker room conversations about the match are metagame interactions. Memorizing words in the Scrabble dictionary is a metagame activity, the honing of in-game skills. The typical playing strategies of a particular Go master are metagame information, useful if you are playing agai...

 1.8% of Gun Related Deaths in the Home Due to Self-Defense

To study the epidemiology of deaths involving firearms kept in the home, we reviewed all the gunshot deaths that occurred in King County, Washington (population 1,270,000), from 1978 through 1983. The medical examiner's case files were supplemented by police records or interviews with investigating officers or both, to obtain specific information about the circumstances, the scene of the incident, the type of firearm involved, and the relationship of the suspect to the victim. A total of 743 ...

 Computer Models as Play

There is, indeed, an "art" to worldplay in the social sciences that fuses narrative with analytical technique. There is also a kinship with the arts in the relationship between imagined world and reality, a point brought home by political scientist and ellow Robert Axelrod. In the early 1960s the teenage Axelrod won the Westinghouse kience Talent Search for a very simple computer simulation of hypothetical lifeforms behaving in an artificial environment. Ever since, he has worked on the appli...

 The Web Enslaves Us With Convenience

In The Matrix, Neo learns that humanity is enslaved by machines. The populace “lives” in a virtual world, unaware that their body heat is being used as an energy source. I see a sort of low-fi parallel of this in our relationship with Facebook. Every member operates in that “free” forum, largely unaware that they’re powering the thing by relinquishing their user data. This scenario is in stark contrast to what we once hoped the web to be. We imagined it as a means of liberating peo...

 Busyness Correlated with Improved Cognitive Performance

Sustained engagement in mentally challenging activities has been shown to improve memory in older adults. We hypothesized that a busy schedule would be a proxy for an engaged lifestyle and would facilitate cognition. Here, we examined the relationship between busyness and cognition in adults aged 50–89. Participants (N = 330) from the Dallas Lifespan Brain Study (DLBS) completed a cognitive battery and the Martin and Park Environmental Demands Questionnaire (MPED), an assessment of busyness...

 Our Relationship to Our Thinking

I invite you to pay attention to anything—the sight of this text, the sensation of breathing, the feeling of your body resting against your chair—for a mere sixty seconds without getting distracted by discursive thought. It sounds simple enough: Just pay attention. The truth, however, is that you will find the task impossible. If the lives of your children depended on it, you could not focus on anything—even the feeling of a knife at your throat—for more than a few seconds, before you...

 Climate Change Science is Based on an 1896 Paper

Our understanding that increasing carbon dioxide levels in the atmosphere could change the climate is not new. The relationship between carbon dioxide, water vapor, and climate was first laid out in detail in 1896 by the Swedish physicist Svante Arrhenius, who estimated that a doubling of carbon dioxide levels would cause global warming of 4.9° to 6.1°C. In his landmark paper, Arrhenius reported that "a simple calculation shows that the temperature in the arctic regions would rise about 8°...

 The Relationship of Industrial Society to Knowledge

Industrial Society is not merely one containing 'industry,' large-scale productive units capable of supplying man's material needs in a way which can eliminate poverty: it is also a society in which knowledge plays a part wholly different from that which it played in earlier social forms, and which indeed possesses a quite different type of knowledge. Modern science is inconceivable outside an industrial society: but modern industrial society is equally inconceivable without modern science. R...

The two are codependent, one cannot exist without the other; therefore, our entire modern world relies on science.
