Quote of the Day

If you want to use your full amount of steam, you must close your valves and direct your power of generating mental steam toward one end. Center your mind on one purpose, one plan, one transaction.

Quote of the Day

In an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.

Quote of the Day

Deep Blue didn't win by being smarter than a human; it won by being millions of times faster than a human. Deep Blue had no intuition. An expert human player looks at a board position and immediately sees what areas of play are most likely to be fruitful or dangerous, whereas a computer has no innate sense of what is important and must explore many more options. Deep Blue also had no sense of the history of the game, and didn't know anything about its opponent. It played chess yet didn't understand chess, in the same way a calculator performs arithmetic bud doesn't understand mathematics.

Quote of the Day

When you have a great and difficult task, something perhaps almost impossible, if you only work a little at a time, every day a little, suddenly the work will finish itself.

Men occasionally stumble over the truth, but most of them pick themselves up and hurry off as if nothing ever happened.

Wisdom Of The Week

I saw, early in the morning, the sun diminish against a backdrop of sky. I saw a circular piece of that sky appear, suddenly detached, blackened, and backlighted; from nowhere it came and overlapped the sun. It did not look like the moon. It was enormous and black. If I had not read that it was the moon, I could have seen the sight a hundred times and never thought of the moon once. (If, however, I had not read that it was the moon—if, like most of the world’s people throughout time, I had simply glanced up and seen this thing—then I doubtless would not have speculated much, but would have, like Emperor Louis of Bavaria in 840, simply died of fright on the spot.) It did not look like a dragon, although it looked more like a dragon than the moon. It looked like a lens cover, or the lid of a pot. It materialized out of thin air—black, and flat, and sliding, outlined in flame.

Seeing this black body was like seeing a mushroom cloud. The heart screeched. The meaning of the sight overwhelmed its fascination. It obliterated meaning itself. If you were to glance out one day and see a row of mushroom clouds rising on the horizon, you would know at once that what you were seeing, remarkable as it was, was intrinsically not worth remarking. No use running to tell anyone. Significant as it was, it did not matter a whit. For what is significance? It is significance for people. No people, no significance. This is all I have to tell you.

In the deeps are the violence and terror of which psychology has warned us. But if you ride these monsters deeper down, if you drop with them farther over the world’s rim, you find what our sciences cannot locate or name, the substrate, the ocean or matrix or ether which buoys the rest, which gives goodness its power for good, and evil. Its power for evil, the unified field: our complex and inexplicable caring for each other, and for our life together here. This is given. It is not learned.

The world which lay under darkness and stillness following the closing of the lid was not the world we know. The event was over. Its devastation lay around about us. The clamoring mind and heart stilled, almost indifferent, certainly disembodied, frail, and exhausted. The hills were hushed, obliterated. Up in the sky, like a crater from some distant cataclysm, was a hollow ring.

You have seen photographs of the sun taken during a total eclipse. The corona fills the print. All of those photographs were taken through telescopes. The lenses of telescopes and cameras can no more cover the breadth and scale of the visual array than language can cover the breadth and simultaneity of internal experience. Lenses enlarge the sight, omit its context, and make of it a pretty and sensible picture, like something on a Christmas card. I assure you, if you send any shepherds a Christmas card on which is printed a three-by-three photograph of the angel of the Lord, the glory of the Lord, and a multitude of the heavenly host, they will not be sore afraid. More fearsome things can come in envelopes. More moving photographs than those of the sun’s corona can appear in magazines. But I pray you will never see anything more awful in the sky.

Quote of the Day

Mood evidently affects the operation of System 1: when we are uncomfortable and unhappy, we lose touch with our intuition.These findings add to the growing evidence that good mood, intuition, creativity, gullibility, and increased reliance on System 1 form a cluster. At the other pole, sadness, vigilance, suspicion, an analytic approach, and increased effort also go together. A happy mood loosens the control of System 2 over performance: when in a good mood, people become more intuitive and more creative but also less vigilant and more prone to logical errors.

A Love Letter to Great Math Teachers

My new book just came out. It’s called Motivated: Designing Math Classrooms Where Students Want to Join In. The book addresses the question: what can teachers do to design motivating environments for their students’ mathematical learning?

[---]

The book is, in the end, a love letter to great math teachers. I have always been moved by great teaching, the way that some people might be moved by great art. When I am in a classroom watching an engaging lesson unfold, it is a profound experience for me. To me, lessons are engaging when students’ humanity is not put underground but is a part of instruction. Students can be a delight, and when learning is connecting with them, it is a joy to watch.

Quote of the Day

We study history not to know the future but to widen our horizons, to understand that our present situation is neither natural nor inevitable, and that we consequently have many more possibilities before us than we imagine.

Quote of the Day

It’s an open debate how much education can boost innate aptitude or IQ, but the trait of “conscientiousness” does consistently predict educational and job success and also subjective happiness. Yet as access to information increases, conscientiousness will become all the more important. It will be less about whose parents could afford Harvard or who could charm the admissions officer, and more and more about who sits down and actually starts trying to master the material. And so a large part of the educational sector will be directed toward boosting conscientiousness, though not always with success.
