In the 1950s and ’60s, another giga-lifesaver, Norman Borlaug, outsmarted evolution to foment the Green Revolution in the developing world.21 Plants in nature invest a lot of energy and nutrients in woody stalks that raise their leaves and blossoms above the shade of neighboring weeds and of each other. Like fans at a…
Though it has become a naturalized part of music-making since the first one was built in 1710, the pianoforte (its name means "soft-loud") was a technical marvel for its time, a machine that changed music in ways that are hard to imagine. Computer pioneer Alan Kay once observed that any technological advance is…
66. Adulthood Earthseed is adulthood. It’s trying our wings, Leaving our mother, Becoming men and women. We’ve been children, Fighting for the full breasts, The protective embrace, The soft lap. Children do this. But Earthseed is adulthood. Adulthood is both sweet and sad. It terrifies. It empowers. We are men and…
Facts, evidence, reason, logic, an understanding of science -- these are good things. (Applause.) These are qualities you want in people making policy. These are qualities you want to continue to cultivate in yourselves as citizens. (Applause.) That might seem obvious. (Laughter.) That's why we honor Bill Moyers or…
When you hear someone longing for the "good old days," take it with a grain of salt. (Laughter and applause.) Take it with a grain of salt. We live in a great nation and we are rightly proud of our history. We are beneficiaries of the labor and the grit and the courage of generations who came before. But I guess it's…
Sinclair and several other prominent gerontologists are presently seeking human therapies based on the long-standing observation that lifelong restriction of caloric intake considerably extends both the healthy and total life span of nearly all species in which it has been tried, including rodents and dogs. Drugs that…
Begin with a story or explanation of the term. Modeling how you use the word in your life or in conversation may be helpful to students. Have students put information into their own words. This process, which I call “recoding,” is necessary to make sure students understand the word. This is a vital step in the memory…
Now that the presidency of George W. Bush is over, the theory that we are better off with unintellectual leaders is just embarrassing, and the reasons for the embarrassment may be quantified. Measuring the psychological traits of public figures, to be sure, has a sketchy history, but the psychologist Dean Simonton has…
Music makes things in our minds, but afterward most of them fade away. What remains? In one old story about Mozart, the wonder child hears a lengthy contrapuntal mass and then writes down the entire score. I do not believe such tales, for history documents so few of them that they seem to be mere legend, though by…
Creation: Allowing students to use technology for creation purposes allows them to tap their creative juices for presentations of knowledge learned. ... I am a fan of not limiting the students and allowing them to choose how they want to "present." A well-written rubric allows a teacher to grade any content in any…
The greatest beauty of roleplaying is its complete lack of limitations. If you can imagine it—or if any of your friends can—you can do it, and magic, strange worlds, supernatural monsters, and legendary heroics are its stock in trade. In the Pathfinder Roleplaying Game, all of these elements combine to weave a…
No two people exactly duplicate each other’s mental stores of items. One person may know A and not B, another may know B and not A, and either knowing A and B, both may get the idea—though not necessarily at once or even soon. Furthermore, the information may not only be of individual items A and B, but even of…
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…
I have used the barcode as a symbol of precise analysis, in all its beauty. Mixed light is sorted into its rainbow of component colours and everybody sees beauty. That is a first analysis. Closer detail reveals fine lines and a new elegance, the elegance of detection, of the bringing of order and understanding…
But our unconscious feats of unweaving and weaving are greater even than this. Think what is happening when you listen to a whole orchestra. Imagine that, superimposed on a hundred instruments, your neighbour in the concert is whispering learned music criticism in your ear, others are coughing and, lamentably…
A way you can think about the perceptron is that it's a device that makes decisions by weighing up evidence. Let me give an example. It's not a very realistic example, but it's easy to understand, and we'll soon get to more realistic examples. Suppose the weekend is coming up, and you've heard that there's going to be…
There was once a brainy baboon, Who always breathed down a bassoon, For he said, 'It appears That in billions of years I shall certainly hit on a tune'.
Many things may become baggage, may become encumbrances if we cling to them blindly and uncriticaliy. Let us take some illustrations. Having made mistakes, you may feel that, come what may, you are saddled with them and so become dispirited; if you have not made mistakes, you may feel that you are free from error and…
If a man wants to succeed in his work, that is, to achieve the anticipated results, he must bring his ideas into correspondence with the laws of the objective external world; if they do not correspond, he will fail in his practice. After he fails, he draws his lessons, corrects his ideas to make them correspond to the…
It is possible that this appearance of non-particulateness is illusory, and that the analogy with genes does not break down. After all, if we look at the inheritance of many genetic characters such as human height or skin-colouring, it does not look like the work of indivisible and unblendable genes. If a black and a…
