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?

Inequality of information- find a place where you know something that many undervalue. Having this inequality of information can give you, your first piece of leverage.
Be an unrelenting machine- Brick walls are there to show you how bad you want something. Commit to your goals and do not waver from them a one bit regardless of what else is there. I took this approach to losing weight and fitness. I have not missed a single 5k run in over a year. It did not matter if I had not slept for two ...
Microbes Rule the World
Microbes make up 80 percent of all biomass, says microbiologist Carl Woese. In one-fifth of a teaspoon of seawater, there are a million bacteria (and 10 million viruses), Craig Venter says, adding, “If you don’t like bacteria, you’re on the wrong planet. This is the planet of the bacteria.” That means that most of the planet’s living metabolism is microbial. When James Lovelock was trying to figure out where the gases come from that make the Earth’s atmosphere such an artifact of ...Stewart Brand describes the state of our world, engineered by microbes and ourselves as the vehicles for their propagation in many cases.
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.
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.
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.
Skeletal Similarities in Mammals
What a piece of work is the mammalian skeleton. I don't mean it is beautiful in itself,
although I think it is. I mean the fact that we can talk about 'the' mammalian skeleton at all: the fact
that such a complicatedly interlocking thing is so gloriously different across the mammals, in all its
parts, while simultaneously being so obviously the same thing throughout the mammals. Our own
skeleton is familiar enough to need no picture, but look at this skeleton of a bat. Isn't it fascinating
ho...There are corresponding bones across species, evolved into other functions.
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.
Animals Can't Be Perfect in all Characteristics
We can expect bodies to be well equipped to
survive, but this does not mean they should be perfect with respect to any one dimension. An
antelope might run faster, and be more likely to escape a leopard, if its legs were a little longer. But
a rival antelope with longer legs, although it might be better equipped to outsprint a predator, has to
pay for its long legs in some other department of the body's economy. The materials needed to
make the extra bone and muscle in the longer legs have to...Energy and materials put into one characteristic means less for another; therefore, species must find balance.
