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...Is the same true of memorizing algorithms to solve the rubiks cube?
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.ShaoLan explains how the symbols break down.
Humans are "Tool Complexes"
Humans are tool complexes—hands for certain tasks, feet, ears, teeth. etc., for others. Using their human tool complexes, human minds, comprebending variable interrelationship principles, invent detached-from-self tools—the bucket can lift out more water from the well than can a pair of cupped human hands—that are more special-case-effective but not used as frequently as their organically integral tools. Humans invent craft tools and industrial tools. The latter are all the tools that c...Similar to a memeplex body of knowledge or a biological complex of living things.
Genius is Hardwork
Men give me some credit for genius. All the genius I have lies in this: When I have a subject in hand, I study it profoundly. Day and night it is before me. I explore it in all its bearings. My mind becomes pervaded with it. Then the effort which I have made is what people are pleased to call the fruit of genius. It is the fruit of labor and thought.Quoting Alexander Hamilton.
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...How the Middle East was the center of scientific progress until religious fever took over it, the same is seen in Jewish and Christian cultures.
The Zodiacal Light
The zodiacal light is caused by sunlight reflecting from meteoric dust that orbits the sun in the plane of the solar system, remnants of the vast nebula of dust and gas out of which the solar system was born more than four billion years ago. Like the planets, this diffuse stream of particles reflects light, although faintly and rarely seen. Moonless nights of winter are the best time to see the zodiacal light. and nowhere better than here, on the Tropic of Cancer, where the plane of the solar...Chet Raymo describes seeing the light of our planetary disk of our solar system intersecting the light of the milky way galaxy.
Thinking About Aliens Stretches the Imagination
The virtue of thinking about life elsewhere is that it forces us to stretch our imaginations. Can we think of alternative solutions to biological problems already solved in one particular way on Earth? For example, the wheel is a comparatively recent invention on the planet Earth. It seems to have been invented in the ancient Near East less than ten thousand years ago. In fact, the high civilizations of Meso- America, the Aztecs and the Mayas, never employed the wheel, except for children's t...The possible life that could evolve in other environments is an imaginative treasure chest.

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...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.
