Nuclear Energy Much Safer than Previously Thought

(p. A14) ROCKVILLE, Md. — The Nuclear Regulatory Commission is approaching completion of an ambitious study that concludes that a meltdown at a typical American reactor would lead to far fewer deaths than previously assumed.

The conclusion, to be published in April after six years of work, is based largely on a radical revision of projections of how much and how quickly cesium 137, a radioactive material that is created when uranium is split, could escape from a nuclear plant after a core meltdown. In past studies, researchers estimated that 60 percent of a reactor core’s cesium inventory could escape; the new estimate is only 1 to 2 percent.
. . .
Big releases of radioactive material would not be immediate, and people within a 10-mile radius would have enough time to evacuate, the study found. The chance of a death from acute radiation exposure within 10 miles is therefore near zero, the study projects, although some people would receive doses high enough to cause fatal cancers in decades to come.
One person in every 4,348 living within 10 miles would be expected to develop a ”latent cancer” as a result of radiation exposure, compared with one in 167 in previous estimates.
”Accidents progress more slowly, in some cases much more slowly, than previously assumed,” Charles G. Tinkler, a senior adviser for research on severe accidents and one of the study’s authors, said in an interview at a commission office building here. ”Releases are smaller, and in some cases much smaller, of certain key radioactive materials.”

On C-SPAN’s book TV I saw the last part of an interesting and entertaining interview with Steven Levy that was originally recorded at the Computer History Museum on April 6, 2011. Levy is the author of of In the Plex which I have not read, but which is now on my to-read list.
At the end of the interview, Levy read a passage from his book about how Larry Page is obsessed with reducing latency, which is a technical term for how long we have to wait for something to happen on a computer.
Isn’t it wonderful that Larry Page is on a crusade to save us from wasted time?

(Note: “latency” appears on the following pages of Steven Levy’s book: 93, 184, 185, 186, 187, 207, 262, and 398.)

If Truman Had Not Used the Bomb, Hundreds of Thousands More American Soldiers Would Have Died

(p. A15) . . . , the author reminds us of the hundreds of thousands of Japanese who had died in the conventional bombings of places like Tokyo and Kyoto while Roosevelt was president, but with relatively little opprobrium attaching to FDR. Father Miscamble cites as well the horrific massacre of innocents for which the Japanese were responsible, a savagery still being unleashed in the summer of 1945, and the awful cost of battle in the Pacific, including 6,000 American dead and 20,000 wounded at Iwo Jima and 70,000 casualties suffered while capturing Okinawa. With these precedents, Herbert Hoover warned Truman that an invasion of the Japanese home islands could result in the loss of between half a million and a million American lives. Marshall, Leahy and Gen. Douglas MacArthur each had his own projected figures, none of them wildly different from Hoover’s.

Under these circumstances, it was inconceivable that Truman would not have ordered the use of a potentially war-winning weapon the moment it could be deployed. It is impossible to imagine the depth of the public’s fury if after the war Americans had discovered that their president, out of concern for his own conscience, had not used the weapons but instead condemned hundreds of thousands of American soldiers to certain death on the beaches and in the cities of mainland Japan.

Confirmation Bias (aka “Pigheadedness”) in Science

(p. 12) In a classic psychology experiment, people for and against the death penalty were asked to evaluate the different research designs of two studies of its deterrent effect on crime. One study showed that the death penalty was an effective deterrent; the other showed that it was not. Which of the two research designs the participants deemed the most scientifically valid depended mostly on whether the study supported their views on the death penalty.
In the laboratory, this is labeled confirmation bias; observed in the real world, it’s known as pigheadedness.
Scientists are not immune. In another experiment, psychologists were asked to review a paper submitted for journal publication in their field. They rated the paper’s methodology, data presentation and scientific contribution significantly more favorably when the paper happened to offer results consistent with their own theoretical stance. Identical research methods prompted a very different response in those whose scientific opinion was challenged.

In Greece “Entrepreneurial Activity Was Denigrated”

(p. A15) Athens

If you’ve ever wondered why so many Greeks succeed in shipping, John Coustas has a plausible theory: “Greek shipping has nothing to do with the Greek state.”
His firm, Danaos Corporation, is a case in point. Mr. Coustas took over the company, which owns container ships, from his father in 1987 and has since transformed it from a three-vessel outfit into the third-largest company of its kind in the world, with a fleet of 56 ships. Danaos is incorporated in the Marshall Islands, a popular and stable jurisdiction for the global industry, and handles many of its operations through its German, Ukrainian, Russian and Tanzanian offices.
Nevertheless, Mr. Coustas is deeply concerned with the fate of his country. The government is now on the brink of default after passing its latest round of spending cuts and tax hikes. Yet the biggest risk to Greece, he says, is brain drain, that “all the good people, who really have something to offer, are either leaving or seriously considering it.”
. . .
On top of misguided government spending, Mr. Coustas says entrepreneurial activity was denigrated for many years and profit was regarded as “wrong.” “Anyone who wanted to make an investment here was considered a kind of bloodsucker.”

The Stinking Past

(p. 356) The people who cleaned cesspits were known as nightsoil men, and if there has ever been a less enviable way to make a living I believe it has yet to be described. They worked in teams of three or four. One man – the most junior, we may assume – was lowered into the pit itself to scoop waste into buckets. A second stood by the pit to raise and lower the buckets, and the third and fourth carried the buckets to a waiting cart. Nightsoil work was dangerous as well as disagreeable. Workers ran the risk of asphyxiation and even of explosions since they worked by the light of a lantern in powerfully gaseous environments. The Gentleman’s Magazine in 1753 related the case of one nightsoil man who went into a privy vault in a London tavern and was overcome almost at once by the foul air. ‘He call’d out for help, and immediately fell down on his face,’ one witness reported. A colleague who rushed to the man’s aid was similarly overcome. Two more men went to the vault, but could not get in because of the foul air, though they did manage to open the door a little, releasing the worst (p. 357) of the gases. By the time rescuers were able to haul the two men out, one was dead and the other was beyond help.

Entrepreneur Jobs Was an Exemplar of Creative Destruction

The clip embedded above from the CNBC web site, was broadcast on CNBC on Weds., Oct. 5, 2011.

I watched several commentaries on Steve Jobs after his death was announced today (Weds., Oct. 5). I think the one above, from CNBC, was one of the best.
It highlights many important aspects of Jobs’ life. That he came back from failure, that he brought us products we didn’t know we needed until he showed us what they could do, that his products disrupted the status quo of whole industries, that at his death he owned more shares of Disney than anyone else. (Steve Jobs and Walt Disney were two of the greatest “project entrepreneurs” of all time.)

Another Nod to Planck’s “Cynical View of Science”

The Max Planck view expressed in the quote below, has been called “Planck’s Principle” and has been empirically tested in three papers cited at the end of the entry.

(p. 12) How’s this for a cynical view of science? “A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.”

Scientific truth, according to this view, is established less by the noble use of reason than by the stubborn exertion of will. One hopes that the Nobel Prize-winning physicist Max Planck, the author of the quotation above, was writing in an unusually dark moment.
And yet a large body of psychological data supports Planck’s view: we humans quickly develop an irrational loyalty to our beliefs, and work hard to find evidence that supports those opinions and to discredit, discount or avoid information that does not.

“Insanely Great” Entrepreneur Steve Jobs Wanted “a Chance to Change the World”

Steve Jobs died yesterday (Weds., October 5, 2011).
Jobs was an innovator of my favorite kind, what I call a “project entrepreneur.” He showed us what excitement and progress is possible if we preserve the institutions that allow entrepreneurial capitalism to exist.
When he was recruiting John Sculley to leave Pepsi and join Apple, Jobs asked him: “Do you want to spend the rest of your life selling sugared water or do you want a chance to change the world?” (p. 90).
Steve Jobs wanted to change the world. He got the job done.

In Middle Ages “Nearly Everyone Itched Nearly All the Time”

(p. 346) . . . in the Middle Ages the spread of plague made people consider more closely their attitude to hygiene and what they might do to modify their own susceptibility to outbreaks. Unfortunately, people everywhere came to exactly the wrong conclusion. All the best minds agreed that bathing opened the epidermal pores and encouraged deathly vapours to invade the body. The best policy was to plug the pores with dirt. For the next six hundred years most people didn’t wash, or even get wet, if they could help it – and in consequence they paid an uncomfortable price. Infections became part of everyday life. Boils grew commonplace. Rashes and blotches were routine. Nearly everyone itched nearly all the time. Discomfort was constant, serious illness accepted with resignation.
