In four photographs of Albert Einstein, taken over a 30-year span between 1911 and 1942 and reproduced in Silvan Schweber's "Einstein & Oppenheimer: The Meaning of Genius" (Harvard, 432 pages, $29.95), he positions himself, whether in a group or alone, so that his left hand is caught by the camera. He holds that hand in a distinctive gesture, with his thumb and forefinger joined to form a little ellipse. Though he tends to face away from the camera, as though indifferent to appearances, he is clearly at pains to keep that left hand visible. The gesture is as much a signal as a symbol.

Geniuses and the Men Hidden Inside Them

Historian David McCullough has said that all teachers of history should be trained storytellers. But there are some stories that Americans would rather not hear.

From last month:

In all his speeches, John McCain urges Americans to make sacrifices for a country that is both “an idea and a cause”.

He is not asking them to suffer anything he would not suffer himself.

But many voters would rather not suffer at all.

From today:

The key demographic – unaffiliated 40+ white voters in the swing states – may be pulled in two different directions. On the one hand, many of them clearly have an instinctive dislike of Barack Obama, because of his sanctimony, his cool demeanour, or because of the colour of his skin. On the other hand, many of them also appear to have developed (if recent state and congressional results are anything to go by) an instinctive dislike of the Republican Party, because of its complete inability to govern successfully. It will be interesting to see which set of associations gets more firmly entrenched by November, because that is what will decide the election. My guess is that people will divide pretty evenly on this question, as the party machines prod them from both sides, and that the final result will be extremely close. What is certain is that the surrounding noise will not diminish, and there will doubtless be a poll to suit every taste, and an elegant piece of analysis to suit every hope. The democratic conversation will continue, but it’s not the one that Dewey had in mind. People are talking, but no one is really listening. For all the fun and fantasy that can be had following this election on the internet, the overriding impression it gives after a while is of tuning into thousands of people as they sit in their cars and complain about the traffic.

Why Didn't We Listen to Their War Stories?

Computational thinking is a fundamental skill for everyone, not just for computer scientists. To reading, writing, and arithmetic, we should add computational thinking to every child’s analytical ability. Just as the printing press facilitated the spread of the three Rs, what is appropriately incestuous about this vision is that computing and computers facilitate the spread of computational thinking.

Computational thinking involves solving problems, designing systems, and understanding human behavior, by drawing on the concepts fundamental to computer science. Computational thinking includes a range of mental tools that reflect the breadth of the field of computer science.

Standing before an audience of about 25 academics, all professors and graduate students specializing in the Middle Ages, in a chilly classroom on the vast campus of Western Michigan University in Kalamazoo, Jeff Persels, a lanky associate professor of French and director of European studies at the University of South Carolina, was reading aloud a scholarly paper at the 43rd International Congress on Medieval Studies. The paper's title was "The Wine in the Urine: Managing Human Waste in French Farce." The paper was about, well, the wine in the urine, or perhaps the urine in the wine. Its topic is a 15th-century farce, or lowlife comic drama, about an adulterous wife who uses a wine bottle as an impromptu chamber pot, with predictably gross results involving her husband and her lover.

If I had to pick the critical technology for the 20th century, the bit of social lubricant without which the wheels would've come off the whole enterprise, I'd say it was the sitcom.

Modern video games mean big business, and big controversy. Yet most of the charges levelled against games—that they stunt minds and spark addiction—are based on an outdated understanding of what gamers do when they sit down to play.

'Rage against the machines' by Tom Chatfield

Paul Graham:

Great cities attract ambitious people. You can sense it when you walk around one. In a hundred subtle ways, the city sends you a message: you could do more; you should try harder.

The surprising thing is how different these messages can be. New York tells you, above all: you should make more money. There are other messages too, of course. You should be hipper. You should be better looking. But the clearest message is that you should be richer.
