Comment They moved the power distrubution equip? (Score 1) 87
It seems to me that moving the power distribution out of the mine NEGATES the supposed archive integrity of the deep mine.

A IR LED and IR sensor with simple amp into a cheap a2d.
A deep red works too but it is really measuring blood oxygen which is out of phase with heartbeat.
You don't have to send people and animals to other star systems!
Send robot probes with DNA sequences stored on computer chips.
These ships would have no life to protect and could travel faster!
When they find a suitable planet... recreate life, human and other, from the synthetic lab.
What is the justification for sales tax on an internet purchase?
Did the state or county provide some service or infrastructure that supported the internet sale?
Did the state or county or city bring anything to the table?
No?
Why then they should bug off!
So if you are sued in another country (UK) by some jerk who feels he can burn you in your country...
The logical response is to place a contract with say a service in Russia or Columbia or somewhere where records are by word of mouth...
to termniate the jerk....
I am NOT advocating it just pointing it out as a logical course of action one might consider...
One must admit it would be much cheaper than an international court case against some rich S.O.B.

Anonymous Coward - yes he is!
An Anonymous Coward has less cred than a Movie Star.
Show some strength and at least choose a nym.
As for the world - What have you done yourself to make it a better place?
as for Dyson...
Project Orion rocked...
His physics rocked.
His space science is a path the Human race was too chicken and bureaucratic to tread.
Dyson sphere
Main article: Dyson sphere
" One should expect that, within a few thousand years of its entering the stage of industrial development, any intelligent species should be found occupying an artificial biosphere which completely surrounds its parent star.[16] "
In 1960 Dyson wrote a short paper for the journal Science, entitled "Search for Artificial Stellar Sources of Infrared Radiation".[17] In it, he theorised that a technologically advanced extraterrestrial civilization might completely surround its native star with artificial structures in order to maximise the capture of the star's available energy. Eventually, the civilisation would completely enclose the star, intercepting electromagnetic radiation with wavelengths from visible light downwards and radiating waste heat outwards as infrared radiation. Therefore, one method of searching for extraterrestrial civilisations would be to look for large objects radiating in the infrared range of the electromagnetic spectrum.
Dyson conceived that such structures would be clouds of asteroid-sized space habitats, though science fiction writers have preferred a solid structure: either way, such an artifact is often referred to as a Dyson sphere, although Dyson himself used the term "shell". Dyson says that he used the word "artificial biosphere" in the article meaning a habitat, not a shape.[18]
[edit] Dyson tree
Main article: Dyson tree
Dyson has also proposed the creation of a Dyson tree, a genetically-engineered plant capable of growing on a comet. He suggested that comets could be engineered to contain hollow spaces filled with a breathable atmosphere, thus providing self-sustaining habitats for humanity in the outer solar system.
" Plants could grow greenhouses...just as turtles grow shells and polar bears grow fur and polyps build coral reefs in tropical seas. These plants could keep warm by the light from a distant Sun and conserve the oxygen that they produce by photosynthesis. The greenhouse would consist of a thick skin providing thermal insulation, with small transparent windows to admit sunlight. Outside the skin would be an array of simple lenses, focusing sunlight through the windows into the interior... Groups of greenhouses could grow together to form extended habitats for other species of plants and animals.[19] "
[edit] Space colonies
" I've done some historical research on the costs of the Mayflower's voyage, and on the Mormons' emigration to Utah, and I think it's possible to go into space on a much smaller scale. A cost on the order of $40,000 per person [1978 dollars] would be the target to shoot for; in terms of real wages, that would make it comparable to the colonisation of America. Unless it's brought down to that level it's not really interesting to me, because otherwise it would be a luxury that only governments could afford.[16] "
Freeman Dyson has been interested in space travel since he was a child, reading such science fiction classics as Olaf Stapledon's Star Maker. As a young man, he worked for General Atomics on the nuclear-powered Orion spacecraft. He hoped Project Orion would put men on Mars by 1965, Saturn by 1970. He's been unhappy for a quarter-century on how the government conducts space travel:
" The problem is, of course, that they can't afford to fail. The rules of the game are that you don't take a chance, because if you fail, then probably your whole program gets wiped out.[16] "
He still hopes for cheap space travel, but is resigned to waiting for private entrepreneurs to develop something new--and cheap.
" No law of physics or biology forbids cheap travel and settlement all over the solar system and beyond. But it is impossible to predict how long this will take. Predictions of the dates of future achievements are notoriously fallible. My guess is that the era of cheap unmanned missions will be the next fifty years, and the era of cheap manned missions will start sometime late in the twenty-first century.
Any affordable program of manned exploration must be centred in biology, and its time frame tied to the time frame of biotechnology; a hundred years, roughly the time it will take us to learn to grow warm-blooded plants, is probably reasonable.[19]

[edit] Space exploration
" A direct search for life in Europa's ocean would today be prohibitively expensive. Impacts on Europa give us an easier way to look for evidence of life there. Every time a major impact occurs on Europa, a vast quantity of water is splashed from the ocean into the space around Jupiter. Some of the water evaporates, and some condenses into snow. Creatures living in the water far enough from the impact have a chance of being splashed intact into space and quickly freeze-dried. Therefore, an easy way to look for evidence of life in Europa's ocean is to look for freeze-dried fish in the ring of space debris orbiting Jupiter.[19] "
[edit] Dyson's transform
Main article: Dyson's transform
Dyson also has some credits in pure mathematics. His concept "Dyson's transform" led to one of the most important lemmas of Olivier Ramaré's theorem that every even integer can be written as a sum of no more than six primes.
the Zealots are always willing to burn a heretic.
Dyson is one of the greats and as Einstein said:
"Greatspirits have always encountered violent opposition from mediocre minds."
And God knows there are a sh*tload of mediocre minds involved with gerbil wormening
Not to mention with Lefties, politicians, movie stars..
If movie stars are in favour of it, it pretty much guarantees it's a bad idea.
Freeman Dyson has, apparently, angered all the right people.
FOR MORE THAN HALF A CENTURY the eminent physicist Freeman Dyson has quietly resided in Princeton, N.J., on the wooded former farmland that is home to his employer, the Institute for Advanced Study, this country's most rarefied community of scholars. Lately, however, since coming "out of the closet as far as global warming is concerned," as Dyson sometimes puts it, there has been noise all around him. Chat rooms, Web threads, editors' letter boxes and Dyson's own e-mail queue resonate with a thermal current of invective in which Dyson has discovered himself variously described as "a pompous twit," "a blowhard," "a cesspool of misinformation," "an old coot riding into the sunset" and, perhaps inevitably, "a mad scientist." Dyson had proposed that whatever inflammations the climate was experiencing might be a good thing because carbon dioxide helps plants of all kinds grow. Then he added the caveat that if CO2 levels soared too high, they could be soothed by the mass cultivation of specially bred "carbon-eating trees,"
His most useful contribution to science was the unification of the three versions of quantum electrodynamics invented by Feynman, Schwinger and Tomonaga.
Wikipedia on Freeman Dyson
Although Dyson has won numerous scientific awards, he has never won a Nobel Prize, which has led Nobel physics laureate Steven Weinberg to state that the Nobel committee has "fleeced" Dyson. Dyson has said that "I think it's almost true without exception if you want to win a Nobel Prize, you should have a long attention span, get ahold of some deep and important problem and stay with it for 10 years. That wasn't my style."
Dyson worked as an analyst for RAF Bomber Command at RAF Wyton during World War II, where he would come to create what would be later known as operational research.
