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... 1

Better to Believe and Be Wrong Than Not Believe Anything
He who says “Better to go without belief forever than believe a lie!” merely shows his own preponderant private horror of becoming a dupe. . . . It is like a general informing his soldiers that it is better to keep out of battle forever than to risk a single wound. Not so are victories either over enemies or over nature gained. Our errors are surely not such awfully solemn things. In a world where we are so certain to incur them in spite of all our caution, a certain lightness of heart se... 1 notes

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.

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... 1 notes

Get a Child Addicted to the Real Wonders of the World
It’s easy to get a child addicted to real wonders if you start early enough. Simply point them out—they are all around us—and include a few references to what was once thought to be true. Take thunder. Explain that a bolt of lightning rips through the air, zapping trillions of air molecules with energy hotter than the Sun. Those superheated molecules explode out of the way with a crack! Then the bolt is gone, and all those molecules smash into each other again as they fill in the emptin...Folksonomies: wonder sense of wonder

An Origami Metaphor for Fetal Development
The sheets of tissue that
fold, invaginate and turn inside out in a developing embryo do indeed grow, and it is that very growth that provides part of the motive force which, in origami, is supplied by the human hand. If
you wanted to make an origami model with a sheet of living tissue instead of dead paper, there is at
least a sporting chance that, if the sheet were to grow in just the right way, not uniformly but faster
in some parts of the sheet than in others, this might automatically cau...Cells divide and fold into new forms, just as origami structures become other structures through new folds.

Enjoying Science Requires Effort
When you have reached and entered the gates of science, how are you to use and enjoy this new and beautiful land?
This is a very important question for you may make a twofold use of it. If you are only ambitious to shine in the world, you may use it chiefly to get prizes, to be at the top of your class, or to pass in examinations; but if you also enjoy discovering its secrets, and desire to learn more and more of nature and to revel in dreams of its beauty, then you will study science for it...
1 Many don't love nature and don't fall in love with science as a result.

The Empty Space in an Atom
A favourite analogy portrays the nucleus as a fly
in the middle of a sports stadium. The nearest neighbouring nucleus is another fly, in the middle of
an adjacent stadium. The electrons of each atom are buzzing about in orbit around their respective flies, smaller than the tiniest gnats, too small to be seen on the same scale as the flies. When we
look at a solid lump of iron or rock, we are 'really' looking at what is almost entirely empty space. It
looks and feels solid and opaque because o...Our senses are not adapted to experience the empty space between atoms.

The Samurai are Prohibited from Professional Sports
Gentlemen of honour, according to the old standards, rode horses, raced chariots, fought, and played competitive games of skill, and the dull, cowardly and base came in thousands to admire, and howl, and bet. The gentlemen of honour degenerated fast enough into a sort of athletic prostitute, with all the defects, all the vanity, trickery, and self-assertion of the common actor, and with even less intelligence. Our Founders made no peace with this organisation of public sports. They did not sp...Folksonomies: voluntary nobility

The Danger of Culture and Science as the Solution
This phenomenon of having a memory for the race, of having an accumulated knowledge passable from one generation to another, was new in the world. But it had a disease in it. It was possible to pass on mistaken ideas. It was possible to pass on ideas which were not profitable for the race. The race has ideas, which were not profitable for the race. The race has ideas, but there are not necessarily profitable.
So there came a time in which the ideas, although accumulated very slowly, were all ...Science is the cure for erroneous memes that enter our culture.
