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…
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…
But the reflected light-waves do more for us than this. They not only make us see things, but they make us see them in different colours. What, you will ask, is this too the work of the sunbeams? Certainly; for if the colour we see depends on the size of the waves which come back to us, then we must see things…
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…
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…
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…
Try to imagine what the electric and magnetic fields look like at present in the space of this lecture room. First of all, there is a steady magnetic field; it comes from the currents in the interior of the earth - that is, the earth's steady magnetic field. Then there are some irregular, nearly static electric fields…
And yet there's so much in real science that's equally exciting, more mysterious, a greater intellectual challenge - as well as being a lot closer to the truth. Did he know about the molecular building blocks of life sitting out there in the cold, tenuous gas between the stars? Had he heard of the footprints of our…
Low was looking to explain why young women have fat on their breasts and buttocks more than on other parts of their bodies. The reason this requires explaining is that young women are different from other human beings in this respect. Older women, young girls, and men of all ages gain fat on their torsos and limbs…
If I could change one thing—this is going to sound stupid—but if I could go back in time and change one thing, I might try to interest some early preliterate people in not ! using their thumbs when they count It could have been the Standard, and it would have made a whole lot of things easier in the modem era. On the…
rhe systematic development of knowledge and technology that we all 'science' originated in the millennia of prehistory, and early vomen were among these first 'scientists'. They invented tools, accumulated knowledge about edible and medicinal plants, and 3robably discovered 'the chemistry of pot-making, the physics of…
No single thing abides; but all things flow. Fragment to fragment clings-the things thus grow Until we know and name them. By degrees They melt, and are no more the things we know. Globed from the atoms falling slow or swift I see the suns, I see the systems lift Their forms; and even the systems and the suns Shall go…
We stand upright-after a little practice-on a ship that rolls because we possess an array of sensory nerve cells buried in our muscles, skin, and joints. The function of these sensors is to provide a constant flow of information to the brain about the movements and location in space of the various parts of our bodies…
John Quincy Adams, Who can write, And Andrew Jackson, Who can fight.
[Obama White House is] the kid in school who waves his A test score in front of the entire class but never gets picked to play baseball. He’s an arrogant nerd, and no matter how smart he is, he can’t hit, he can’t throw and he can’t run.
Let's turn again to the golden boy. As you meet his haughty gaze, let me read you some of the things Roger Ebert has written about video games and art. "I believe art is created by an artist. If you change it, you become the artist." "Art seeks to lead you to an inevitable conclusion, not a smorgasbord of choices."…
White people discovered the Galapagos Islands in 1535 when a Spanish ship came upon them after being blown off course by a storm. Nobody was living there, nor were remains of any human settlement ever found there. This unlucky ship wished nothing more than to carry the Bishop of Panama to Peru, never losing sight of…
1 In the beginning God created the heavens and the earth. 2 Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters. 3 And God said, “Let there be light,” and there was light. 4 God saw that the light was good, and he separated the light from…
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…
But the fount of motives lies in the individual life, it lies in silent and deliberate reflections, and at this, the most striking of all the rules of the samurai aims. For seven consecutive days in the year, at least, each man or woman under the Rule must go right out of all the life of man into some wild and…
