Colonizing the Heavens

Fantasy and Science Fiction - A Scientist's Notebook: "But to wait for the right time might mean waiting forever, risking a decline from which humanity might never recover. History has a consistent record of the good happpening alongside the bad; to hesitate might be disastrous, hurling us into the irreversible decline of Arnold Toynbee's two dozen failed civilizations, with no new ground upon which to begin again. Such was the argument against the 'prioritizers.'

Asimov wrote to the skeptics:
'I have received a number of letters concerning my article 'Colonizing the Heavens.'

Some call it fiction. (Real nonsense, I suppose, like reaching the Moon.)

Some say I am trying to subvert the doctrine of Zero Population Growth. (As though it weren't possible to try to colonize space and stop the population growth, too. They are not mutually exclusive.)

Some say it is too expensive. (Not if the world stops supporting military machines.)

Some say that nobody wants an engineered environment. (Nobody? How many people are living in caves these days?)

Some say that nobody would ever want to cross space in three days to live in a space colony. (This from people whose ancestors two or three generations back probably crossed the Atlantic in steerage, or crossed the western desert in covered wagons.)

Some say that Third World people would never go. (Sure. Only aristocrats fled to the New World. All the tired, the poor, the huddled masses yearning to breathe free never came, did they?)

Some say let's solve our problems on Earth before we try to colonize space. (Someone said that to the Pilgrims. Come on, they said, let's solve our problems right here in Europe.)'
Classic stuff. For Asimov, colonies were not primarily technological feats. He echoed the prevailing historical sense of this age: that frontiers have shaped our world by unleashing new ideas with the European explosion outward. These ideas might have died except for the unrestricted ground of the frontier, where the old cultures could not kill them with preemptive criticism and outright suppression."

NEWS : "The 40-year-old Mr. Everett was raised in McLean, Va., with his sister Elizabeth, mother Nancy and father Hugh Everett III, a quantum physicist who in 1957 proposed a formal theory of parallel universes known as 'The Many-Worlds Interpretation of Quantum Mechanics.' 'Everett's work has boggled minds inside and outside physics for more than four decades,' reported Scientific American in last month's issue. Mr. Everett said his brilliant father wasn't communicative at home. When I asked him what the conversation was like around the breakfast table, he replied, 'There wasn't any.' 'Physicists and geniuses don't always make great family men. I lived with him for 18 years and I learned more about him from the Internet.' Mr. Everett's family was a heartrending source of inspiration for his most notable work, the 1998 album 'Electro-Shock Blues' (DreamWorks), written after his sister committed suicide and h...

Digital Cam media safe to fly with

Technocrat.net : "Recent tests found no evidence of X-ray scanner damage to digital camera media cards or to the images they hold. The tests of scanner models currently in use in the U.S. transportation industry were jointly conducted by the International Imaging Industry Association (I3A), the leading global association for the imaging industry; SanDisk Corporation, a manufacturer of digital media cards; and the U.S. Transportation Security Administration (TSA). These findings mean that digital cameras and their image storage media can travel safely in either checked or carry-on bags, which will be reassuring to holiday travelers. And though they were not explicitly tested, it is likely that images on camera-phones will be safe in either situation as well. More care is needed for cameras with film, however, as the X-ray scanners for both checked and carry-on luggage can fog both developed and undeveloped film."

Artist turns animals into everyday objects

Ananova - A Chilean artist is making a name for herself with an exhibition in which stuffed animals are transformed into household objects. Artworks on display include a chick turned into a lamp, and 'sheep bag' - a lamb carcass fitted with handles. Artist Caterina Purdy says her exhibition at the Experimental Arts Centre in Santiago is intended to be humorous but also makes a serious point. She told Las Ultimas Noticias online: 'It is possible to see my work as something scary, but I find it beautiful. 'There is also irony and humour in my objects as well as a criticism of the way animals are treated by society.'"
