Sports, Complexity, and the Ten-Thousand-Hour Rule : The New Yorker

Sports, Complexity, and the Ten-Thousand-Hour Rule : The New Yorker:

As it happens, I have been a runner and a serious track-and-field fan my entire life, and I have never seen a boy who was slow become fast either. For that matter, I’ve never met someone who thinks a boy who was slow can become fast. Epstein has written a wonderful book. But I wonder if, in his zeal to stake out a provocative claim on this one matter, he has built himself a straw man. The point of Simon and Chase’s paper years ago was that cognitively complex activities take many years to master because they require that a very long list of situations and possibilities and scenarios be experienced and processed. There’s a reason the Beatles didn’t give us “The White Album” when they were teen-agers. And if the surgeon who wants to fuse your spinal cord did some newfangled online accelerated residency, you should probably tell him no. It does not invalidate the ten-thousand-hour principle, however, to point out that in instances where there are not a long list of situations and scenarios and possibilities to master—like jumping really high, running as fast as you can in a straight line, or directing a sharp object at a large, round piece of cork—expertise can be attained a whole lot more quickly. What Simon and Chase wrote forty years ago remains true today. In cognitively demanding fields, there are no naturals.

[Gladwell and Epstein go at it. Looking forward to reading the book. And don’t miss this either.]

Fukushima leak is ‘much worse than we were led to believe’

BBC News – Fukushima leak is ‘much worse than we were led to believe’:

The Japanese nuclear energy watchdog raised the incident level from one to three on the international scale that measures the severity of atomic accidents.

This was an acknowledgement that the power station was in its greatest crisis since the reactors melted down after the tsunami in 2011.

But some nuclear experts are concerned that the problem is a good deal worse than either Tepco or the Japanese government are willing to admit.

They are worried about the enormous quantities of water, used to cool the reactor cores, which are now being stored on site.

Some 1,000 tanks have been built to hold the water. But these are believed to be at around 85% of their capacity and every day an extra 400 tonnes of water are being added.

“The quantities of water they are dealing with are absolutely gigantic,” said Mycle Schneider, who has consulted widely for a variety of organisations and countries on nuclear issues.

“What is the worse is the water leakage everywhere else – not just from the tanks. It is leaking out from the basements, it is leaking out from the cracks all over the place. Nobody can measure that.

[How many times do we need to go down this road? And guess where that sea water is headed?]
