 Degenerate Strategies and Cheating

Why isn't using a degenerate strategy considered cheating? Degenerate strategies take advantage of weaknesses in the rules of a game, but do not actually violate the rules. What kind of player would play in this way? The answer is both a dedicated player, who is overzealously seeking the perfect strategy, and an unsportsmanlike player, who has found a hole in the rules to exploit, even though he understands that he is not playing the game the way it was intended. These two kinds of players ca...

 A Cerebral Cortex Makes Animals Programmable

As we ascend the scale of cerebral development the possibility of teaching increases. It becomes possible to domesticate and train these higher-brain animals in just the measure that their brains are developed. You can teach very little to a fish or a reptile, but directly you come to the higher cerebral mammals you are confronted by the new possibility of establishing an artificial, taught, motive system to control, supplement or altogether replace natural instinct. You must catch them young...

 An Aquarium Teaches Kids About Domestic Life

And what, I ask you, are we to think of the viviparous fish, those that actually pair off in no uncertain manner and a little later bring forth living young! (You catch the drift?) What of the Guppyi, the Helleri, the Tetras and Danios and other tropicals with which our apartments are full to overflowing? Well, at least they keep our own offspring off the streets; you can hardly pry them away from the tank. They might miss something. I always say a small aquarium containing several of these d...

 The Rate of Change of a Rate of Change

In scientific thought we adopt the simplest theory which will explain all the facts under consideration and enable us to predict new facts of the same kind. The catch in this criterion lies in the word 'simplest'. It is really an aesthetic canon such as we find implicit in our criticisms of poetry or painting. The layman finds such a law as dx/dt = K(d^2x/dy^2) much less simple than 'it oozes', of which it is the mathematical statement. The physicist reverses this judgment, and his statement ...

 A Paucity of Diversity in Supernatural Beings

In principle, there should be no limit to the diversity of supernatural beings that humans can imagine. However, as the anthropologist Pascal Boyer has argued, only a limited repertoire of such beings is exploited in human religions. Its members—ghosts, gods, ancestor spirits, dragons, and so on—have in common two features: 1. They each violate some major intuitive expectations about living beings: the expectation of mortality, of belonging to one and only one species, of being limited ...

 Rounded Numbers are Cultural Attractors

Rounded numbers are cultural attractors: They are easier to remember and provide better symbols for magnitudes. So we celebrate twentieth wedding anniversaries, hundredth issues of journals, the millionth copy sold of a record, and so on. This, in turn, creates a special cultural attractor for prices, just below rounded numbers—$9.99 or $9,990 are likely price tags—so as to avoid the evocation of a higher magnitude.

 加油 as a Term of Encouragement

The Chinese characters say 加油 (Jia1 you2).加 is composed of 力 (power) and 口 (mouth). It means 'to add'油 is made out of 水 (氵, water) and 由(from/ due). It means oil.加(to add) 油(oil)= add oil or make an extra effort 加油 is a terribly common phrase in day to day life. If you want to encourage someone to carry on great work, or in a sports competition, you say 加油! A bit like 'go on!' in English. Of course another literal meaning of 加油 is to refuel.

 Study is More Efficient Than Contemplation

吾嘗終日而思矣,不如須臾之所學也。吾嘗跂而望矣,不如登高之博見也。登高而招,臂非加長也,而見者遠;順風而呼,聲非加疾也,而聞者彰。假輿馬者,非利足也,而致千里;假舟楫者,非能水也,而絕江河。君子生非異也,善假於物也。

[Translated] Once I spent an entire day in thought, but it was not as good as a moment of study. Once I stood on tiptoe to gaze into the distance, but it was not as good as climbing to a high place to get a broad view. Climbing to a high place and waving will not make your arm any longer, but you can be seen from farther away. Shouting down the wind will give your voice no added urgency, but you can be heard more distinctly. By borrowing a horse and carriage you will not improve your feet, but you can cover a thousand li. By borrowing a boat and paddles you will not improve your ability in water, but you can cross rivers and seas. The noble person is by birth no different from others, but he is good at borrowing from external things.

 History of Science and Religion

Some people want to put warning stickers on biology textbooks, saying that the theory of evolution is just one of many theories, take it or leave it. Now, religion long predates science; it'll be here forever. That's not the issue. The problem comes when religion enters the science classroom. There's no tradition of scientists knocking down the Sunday school door, telling preachers what to teach. Scientists don't picket churches. By and arge—though it may not look this way today—science a...

 Davy Refused to Patent His Safety Lamp

John Buddle, now entirely won over by Davy, was also concerned about a reward. By August there were 144 safety lamps ‘in daily use’ at Walls End, and they were rapidly spreading to all the other collieries in the North-East.91 Buddle urged Davy to take out a patent, pointing out that he could not only make his fortune but control the quality of the lamps issued to miners. Davy consistently refused, although he knew his colleague William Wollaston had made a fortune with a patent on proces...
