Grid: innovation or marketing?


In the overdose of information that we experience everyday, in April i found the following news:

Coming soon: superfast internet called "Grid"

Most of the articles about Grid are based on one article (April 6, 2008) of british Times. In the article you can read the words of David Britton, professor of physics at Glasgow University and a leading figure in the grid project: "With this kind of computing power, future generations will have the ability to collaborate and communicate in ways older people like me cannot even imagine". It's a kind of sentence that can mean everything and nothing at the same time, it sounds like an advertising of a new product. Have scientists become expert of marketing?

Not huge difference of information since another article of Guardian (July 3 2003)
Welcome to the grid: unlimited PC power at your fingertips

another article full of hype:
The Internet's over ... here comes the Grid
Daily Mirror, 7 April 2008

What is the Grid?

A very fast speed network is obviously a positive invention but what is the
content of this network? What could be the benefit for "common" people? They
didn't tell us, but they (Ian Bird, project leader for Cern's high-speed
computing project) said "It will lead to what's known as cloud computing,
where people keep all their information online and access it from anywhere".
And the privacy? Who can guarantee that corporations won't search through my
private information that i could store online?

I'm not saying that the Grid is useless, probably it could be very useless,
but could anyone explain the usefulness to normal people instead of using
trendy slogans?
Is it possible to see the day when some journalists ask simple questions, instead
of just repeating/translating what they saw on the net?

In another site, at last we can read some specific information:

The EGEE Grid consists of 41,000 CPU available to users 24 hours a day, 7 days a week, in addition to about 5 PB disk (5 million Gigabytes) + tape MSS of storage, and maintains 100,000 concurrent jobs. Having such resources available changes the way scientific research takes place. The end use depends on the users' needs: large storage capacity, the bandwidth that the infrastructure provides, or the sheer computing power available.

You can see the blog of David Britton (don't expect much because he
started blogging 1 month ago)

The only flaw of Nicole Kidman



Please, Nicole Kidman, i know you've got contract from Nintendo for Brain Training, but check things before you say: "I've quickly found that training my brain is a great way to keep my mind feeling young"

Sense About Science is an independent charitable trust. They respond to the misrepresentation of science and scientific evidence on issues that matter to society, from scares about plastic bottles, fluoride and the MMR vaccine to controversies about genetic modification, stem cell research and radiation.

In January 2007 in a special leaflet called Sense About… Science for Celebrities, (get it here, it's a 2 page leaflet; they realeased a 2 page leaflet and they got national and international coverage! If you criticize celebrities, you get good coverage, don't you?) scientists told celebrities: “Before making scientific claims check your facts - all it takes is a phone call”. It showed how easily some mistakes could have been avoided and gave a phone number for celebrities to call so that Sense About Science could connect them with scientists, scientific societies and charities.
After one year the same organization has just realeased a new report about celebrities and science during 2007, here you can download the 7 page file.

Professor Peter McNaughton (pharmacologist, Cambridge University) gives a perfect statement: "Celebrities occupy a powerful position - they have access to the media in a way that scientific experts generally do not. I am delighted that they appear to have been getting their facts straighter over the last year. Long may it continue"

The file is interesting but there is a disappointing part. In the section "Earth science" they repeated one sentence of Matt Helders (drummer for the Arctic Monkeys; is he a celebrity??) and one sentence of Heather Mills; after that the reader expects a perfect answer from scientists but i only got "scientists couldn't respond in fewer than three sentences, so we have been unable to address this one." Excuse me?
Using (and changing, obviously) the words of Professor McNaughton: "Scientists occupy a powerful position - they have access to the laboratories, to the public and private funds and to all kind of studies in a way that common people generally do not. [i'm adding] Therefore, if you don't have space to criticize some sentences, why repeat them? Let's assume those sentences are untrue: why repeat untrue sentences without any criticism?"

New details about Manhattan Project



An interesting article from New York Times:
a journalist talks to Robert Norris, who has chronicled the actual New York roots of the original Manhattan Project (secret project to develop the first nuclear weapon atomic bomb during World War II by the United States) in a new book called “The Manhattan Project” (Black Dog & Leventhal).

Why They Called It the Manhattan Project
By WILLIAM J. BROAD
Published: October 30, 2007

By nature, code names and cover stories are meant to give no indication of the secrets concealed. “Magic” was the name for intelligence gleaned from Japanese ciphers in World War II, and “Overlord” stood for the Allied plan to invade Europe.

Many people assume that the same holds true for the Manhattan Project, in which thousands of experts gathered in the mountains of New Mexico to make the world’s first atom bomb.

Robert S. Norris, a historian of the atomic age, wants to shatter that myth.

In “The Manhattan Project” (Black Dog & Leventhal), published last month, Dr. Norris writes about the Manhattan Project’s Manhattan locations. He says the borough had at least 10 sites, all but one still standing. They include warehouses that held uranium, laboratories that split the atom, and the project’s first headquarters — a skyscraper hidden in plain sight right across from City Hall.

“It was supersecret,” Dr. Norris said in an interview. “At least 5,000 people were coming and going to work, knowing only enough to get the job done.”

Manhattan was central, according to Dr. Norris, because it had everything: lots of military units, piers for the import of precious ores, top physicists who had fled Europe and ranks of workers eager to aid the war effort. It even had spies who managed to steal some of the project’s top secrets.

“The story is so rich,” Dr. Norris enthused. “There’s layer upon layer of good stuff, interesting characters.”

Still, more than six decades after the project’s start, the Manhattan side of the atom bomb story seems to be a well-preserved secret.

Dr. Norris recently visited Manhattan at the request of The New York Times for a daylong tour of the Manhattan Project’s roots. Only one site he visited displayed a public sign noting its role in the epochal events. And most people who encountered his entourage, which included a photographer and videographer, knew little or nothing of the atomic labors in Manhattan.

“That’s amazing,” Alexandra Ghitelman said after learning that the buildings she had just passed on inline skates once held tons of uranium destined for atomic weapons. “That’s unbelievable.”

While shock tended to be the main reaction, some people hinted at feelings of pride. More than one person said they knew someone who had worked on the secret project, which formally got under way in August 1942 and three years later culminated in the atomic bombing of Japan. In all, it employed more than 130,000 people.

Dr. Norris is also the author of “Racing for the Bomb” (Steerforth, 2002), a biography of Gen. Leslie R. Groves, the project’s military leader. As his protagonist had done during the war, Dr. Norris works in Washington. At the Natural Resources Defense Council, he studies and writes about the nation’s atomic facilities.

Dr. Norris began his day of exploration by taking the train to New York from Washington, coming into Pennsylvania Station just as General Groves had done dozens of times during the war to visit project sites.

“Groves didn’t want the job,” Dr. Norris remarked outside the station. “But his foot hit the accelerator and he didn’t let up for 1,000 days.”

For tour assistance, Dr. Norris brought along his own books as well as printouts from “The Traveler’s Guide to Nuclear Weapons,” a CD by James M. Maroncelli and Timothy L. Karpin that features little-known history of the nation’s atom endeavors.

We headed north to the childhood home of J. Robert Oppenheimer, the eccentric genius whom General Groves hired to run the project’s scientific side as well as its sprawling New Mexico laboratory. Last year, a biography of Oppenheimer, “American Prometheus” (Knopf, 2005), won the Pulitzer Prize.

“One of the most famous scientists of the 20th century,” Dr. Norris noted, got his start “walking these streets” and attending the nearby Ethical Culture School.

Oppenheimer and his parents lived at 155 Riverside Drive, an elegant apartment building at West 88th Street. The superintendent, Joe Gugulski, said the family lived on the 11th floor, overlooking the Hudson River.

“One of my tenants read the book,” Mr. Gugulski told us. “So I looked it up.” To his knowledge, Mr. Gugulski added, no other atomic tourists had visited the building.

The Oppenheimers decorated their apartment with original artwork by Picasso, Rembrandt, Renoir, Van Gogh and CĂ©zanne, according to “American Prometheus.” His mother encouraged young Robert to paint.

By the late 1930s and early 1940s, blocks away at Columbia University, scientists were laboring to split the atom and release its titanic energies. We made our way across campus — with difficulty because of protests over the visit of President Mahmoud Ahmadinejad of Iran, which is widely suspected of harboring its own bomb program.

Dr. Norris noted that the Manhattan Project led to “many of our problems today.”

The Pupin Physics Laboratories housed the early atom experiments, Dr. Norris said. But the tall building, topped by observatory domes, has no plaque in its foyer describing its nuclear ties.

Passing students and pedestrians answered “no” and “kind of” when asked if they knew of the atom breakthroughs at Pupin Hall. Dr. Norris said the Manhattan Project, at its peak, employed 700 people at Columbia. At one point, the football team was recruited to move tons of uranium. That work, he said, eventually led to the world’s first nuclear reactor.

After lunch, we headed to West 20th Street just off the West Side Highway. The block, on the fringe of Chelsea, bristled with new galleries, and Kingdom Hall of Jehovah’s Witnesses. On its north side, three tall buildings once made up the Baker and Williams Warehouses, which held tons of uranium.

Two women taking a cigarette break said they had no idea of their building’s atomic past. “It’s horrible,” said one.

Dr. Norris’s “Traveler’s Guide” fact sheet said the federal government in the late 1980s and early 1990s cleaned the buildings of residual uranium. Workers removed more than a dozen drums of radioactive waste, according to the Department of Energy in Washington. “Radiological surveys show that the site now meets applicable requirements for unrestricted use,” a federal document said in 1995.

We moved to Manhattan’s southern tip and worked our way up Broadway along the route known as the Canyon of Heroes, the scene of many ticker-tape parades amid the skyscrapers.

At 25 Broadway, we visited a minor but important site — the Cunard Building. Edgar Sengier, a Belgian with an office here, had his company mine about 1,200 tons of high-grade uranium ore and store it on Staten Island in the shadow of the Bayonne Bridge. Though a civilian, he knew of the atomic possibilities and feared the invading Germans might confiscate his mines.

Dr. Norris said General Groves, on his first day in charge, sent an assistant to buy all that uranium for a dollar a pound — or $2.5 million. “The Manhattan Project was off to a flying start,” he said, adding that the Belgian entrepreneur in time supplied two-thirds of all the project’s uranium.

We walked past St. Paul’s Chapel and proceeded to the soaring grandeur of the Woolworth Building, once the world’s tallest, at 233 Broadway.

A major site, it housed a front company that devised one of the project’s main ways of concentrating uranium’s rare isotope — a secret of bomb making. On the 11th, 12th and 14th floors, the company drew on the nation’s scientific best and brightest, including teams from Columbia.

Dr. Norris said the front company’s 3,700 employees included Klaus Fuchs, a Soviet spy. “He was a substantial physicist in his own right,” Dr. Norris said. “He contributed to the American atom bomb, the Soviet atom bomb and the British atom bomb.”

So how did the Manhattan Project get its name, and why was Manhattan chosen as its first headquarters?

Dr. Norris said the answer lay at our next stop, 270 Broadway. There, at Chambers Street, on the southwest corner, we found a nondescript building overlooking City Hall Park.

It was here, Dr. Norris said, that the Army Corps of Engineers had its North Atlantic Division, which built ports and airfields. When the Corps got the responsibility of making the atom bomb, it put the headquarters in the same building, on the 18th floor.

“That way he didn’t need to reinvent the wheel,” Dr. Norris said of General Groves. “He used what he had at his fingertips — the entire Corps of Engineers infrastructure.”

Dr. Norris added that the Corps at that time included “extraordinary people, the best and brightest of West Point.”

In time, the office at 270 Broadway ran not only atom research and materials acquisition but also the building of whole nuclear cities in Tennessee, New Mexico and Washington State.

The first proposed name for the project, Dr. Norris said, was the Laboratory for the Development of Substitute Materials. But General Groves feared that would draw undo attention.

Instead, General Groves called for the bureaucratically dull approach of adopting the standard Corps procedure for naming new regional organizations. That method simply noted the unit’s geographical area, as in the Pittsburgh Engineer District.

So the top-secret endeavor to build the atom bomb got the most boring of cover names: the Manhattan Engineer District, in time shortened to the Manhattan Project. Unlike other Corps districts, however, it had no territorial limits. “He was nuts about not attracting attention,” Dr. Norris said.

Manhattan’s role shrank as secretive outposts for the endeavor sprouted across the country and quickly grew into major enterprises. By the late summer of 1943, little more than a year after its establishment, the headquarters of the Manhattan Project moved to Oak Ridge, Tenn.

Despite this dispersal, Dr. Norris said, scientists and businesses in Manhattan, including The New York Times, continued to aid the atomic project.

In April 1945, General Groves traveled to the newspaper’s offices on West 43rd Street. He asked that a science writer, William L. Laurence, be allowed to go on leave to report on a major wartime story involving science.

As early as 1940, before wartime secrecy, Mr. Laurence had reported on the atomic breakthroughs at Pupin Hall.

Now, Dr. Norris said, Mr. Laurence went to work for the Manhattan Project and became the only reporter to witness the Trinity test in the New Mexican desert in July 1945, and, shortly thereafter, the nuclear bombing of Japan.

The atomic age, Mr. Laurence wrote in the first article of a series, began in the New Mexico desert before dawn in a burst of flame that illuminated “earth and sky for a brief span that seemed eternal.”

In Manhattan, the one location that has memorialized its atomic connection had nothing to do with making or witnessing the bomb, but rather with managing to survive its fury.

The spot is on Riverside Drive between 105th and 106th Streets. There, in a residential neighborhood, in front of the New York Buddhist Church, is a tall statue of a Japanese Buddhist monk, Shinran Shonin, who lived in the 12th and 13th centuries. In peasant hat and sandals, holding a wooden staff, the saint peers down on the sidewalk.

The statue survived the atomic bombing of Hiroshima, standing a little more than a mile from ground zero. It was brought to New York in 1955. The plaque calls the statue “a testimonial to the atomic bomb devastation and a symbol of lasting hope for world peace.”

The statue stands a few blocks from Columbia University, where much of the bomb program began.

“I wonder how many New Yorkers know about it,” Dr. Norris said of the statue, “and know the history.”

Scientists and communication



Michael Skapinker (Associate Editor of the FT and a columnist) writes: "Journalists often demand definitive answers. Scientists need to explain that they are not always possible."


Scientists must learn to talk to the media
By Michael Skapinker

Published: October 29 2007 17:53

I occasionally speak to school students about journalism and they usually ask the same questions. Have you interviewed anyone famous? (Richard Branson and John Cleese seem to pass muster.) What do you do if there is no news? (There is always news.) What should I study if I want to be a journalist?

I spend some time on the last one, advising them to study whatever they are most interested in, whether it is history, foreign languages or economics. The craft of journalism is something they can learn later. Far better to acquire some knowledge to bring to the job. And I tell them there is a desperate need for more scientists who can broadcast and write.

Science and the media have not always served each other well. Last week, the Royal Society of Arts and the Reuters Institute for the Study of Journalism hosted a stimulating discussion on the theme “Do scientists get the media they deserve?” The speakers were Craig Venter, the genome research pioneer, and Niall Dickson, a former BBC journalist who is now chief executive of the King’s Fund, the independent health charity.

On the basis of his performance, Mr Venter, who was once described in The New Yorker as an “idiot”, does not get the press he deserves. He was amusing and quietly spoken. He was also easier on journalists than Mr Dickson, who worried about the media’s tendency to sensationalise, to oversimplify and to reduce the world to black and white.

On the other hand, Mr Venter said scientists, driven by their need for research grants, were guilty of exaggerating what they hoped to achieve. They were happy if they fell 50 per cent short of their stated goals. Business executives who fell even slightly short were adjudged failures.

Mr Dickson said he was not entirely pessimistic. Organisations such as the Science Media Centre, whose director, Fiona Fox, chaired the discussion, helped scientists explain themselves. (“Large numbers are very difficult to imagine,” the centre tells scientists. “Rather than 1 in 1,200, talk about one child in a large secondary school.”) The centre also helps journalists with “thumbnail sketches” entitled, for example: “What is peer review? Peer review is where scientists open their research to the scrutiny of other experts in the field.”

Based on my experience as a non-scientific journalist, occasionally writing about controversies such as mobile phone emissions, genetically modified food and the measles, mumps and rubella vaccination, here are a few other suggestions for scientists.

First, do not assert a certainty that science cannot sustain. Journalists often demand definitive answers. Scientists need to explain this is not always possible. This can work. The Mobile Telecommunications and Health Research Programme last month issued a nuanced report on the health risks from mobile phones.

The programme, funded by the UK government and the industry, found no evidence of ill health in mobile phone users but added that “cancer symptoms are rarely detectable until 10 to 15 years after the cancer producing event and, since few people have used their phones that long, it is too early to say for certain whether mobile phones could lead to cancer or indeed to other diseases”.

The Daily Express reported it this way: “Scientists have admitted there may be long-term health risks from using mobile phones. A major study published on Monday found no evidence of a link between short-term use and brain cancer. But experts behind the research said it was too early to know what will happen in future.” Not bad.

Second, people, however well-meaning, generally make sacrifices for the wider good only if they can see benefits for themselves or their families. People may be prepared to buy hybrid cars because they can see that global warming might affect their loved ones.

But European consumers refused to set aside their suspicions about genetically modified food just because US companies claimed it would help farmers in the developing world. Consumers could see nothing in it for themselves and they suspected the alleged benefits would accrue mainly to the companies. Third, while people may be prepared to tolerate some risk for themselves, they are prepared to accept far less for their children.

When a lone British doctor claimed the MMR vaccine could cause autism (an assertion that has attracted no scientific support), public health officials violated all these suggestions.

They baldly asserted that the vaccine was safe, when people knew no vaccination was completely safe. They told parents who refused to vaccinate their children that they were risking the health of the community. Parents were not prepared to sacrifice their own children for the community.

With patient persuasion, and the discrediting of the alarmist research, immunisation rates in England are climbing again but, at 85 per cent, are still short of the 95 per cent needed to ensure widespread immunity.
