Sergey Brin’s Search for a Parkinson’s Cure
From Wired:
Several evenings a week, after a day’s work at Google headquarters in Mountain View, California, Sergey Brin drives up the road to a local pool. There, he changes into swim trunks, steps out on a 3-meter springboard, looks at the water below, and dives.
Brin is competent at all four types of springboard diving—forward, back, reverse, and inward. Recently, he’s been working on his twists, which have been something of a struggle. But overall, he’s not bad; in 2006 he competed in the master’s division world championships. (He’s quick to point out he placed sixth out of six in his event.)
The diving is the sort of challenge that Brin, who has also dabbled in yoga, gymnastics, and acrobatics, is drawn to: equal parts physical and mental exertion. “The dive itself is brief but intense,” he says. “You push off really hard and then have to twist right away. It does get your heart rate going.”

The internet: Everything you ever need to know
From The Observer:
In spite of all the answers the internet has given us, its full potential to transform our lives remains the great unknown. Here are the nine key steps to understanding the most powerful tool of our age – and where it’s taking us.

From Scientific American:
Editor’s Note: We are republishing this article by Paul Dirac from the May 1963 issue of Scientific American, as it might be of interest to listeners to the June 24, 2010, and June 25, 2010 Science Talk podcasts, featuring award-winning writer and physicist Graham Farmelo discussing The Strangest Man, his biography of the Nobel Prize-winning British theoretical physicist.
In this article I should like to discuss the development of general physical theory: how it developed in the past and how one may expect it to develop in the future. One can look on this continual development as a process of evolution, a process that has been going on for several centuries.

What Is I.B.M.’s Watson?
From The New York Times:
“Toured the Burj in this U.A.E. city. They say it’s the tallest tower in the world; looked over the ledge and lost my lunch.”
This is the quintessential sort of clue you hear on the TV game show “Jeopardy!” It’s witty (the clue’s category is “Postcards From the Edge”), demands a large store of trivia and requires contestants to make confident, split-second decisions. This particular clue appeared in a mock version of the game in December, held in Hawthorne, N.Y. at one of I.B.M.’s research labs. Two contestants — Dorothy Gilmartin, a health teacher with her hair tied back in a ponytail, and Alison Kolani, a copy editor — furrowed their brows in concentration. Who would be the first to answer?
Neither, as it turned out. Both were beaten to the buzzer by the third combatant: Watson, a supercomputer.

Mind Over Mass Media
From the New York Times:
NEW forms of media have always caused moral panics: the printing press, newspapers, paperbacks and television were all once denounced as threats to their consumers’ brainpower and moral fiber.
So too with electronic technologies. PowerPoint, we’re told, is reducing discourse to bullet points. Search engines lower our intelligence, encouraging us to skim on the surface of knowledge rather than dive to its depths. Twitter is shrinking our attention spans.
But such panics often fail basic reality checks. When comic books were accused of turning juveniles into delinquents in the 1950s, crime was falling to record lows, just as the denunciations of video games in the 1990s coincided with the great American crime decline. The decades of television, transistor radios and rock videos were also decades in which I.Q. scores rose continuously.
