FABLES OF THE RECONSTRUCTION:
Science as Metaphor: Where does Brian Greene stand in the pantheon of physicists? (Amanda Schaffer, July 6, 2004, Slate)
With his 1999 best seller The Elegant Universe, a NOVA special, and the recent release of a second book, The Fabric of the Cosmos, Columbia professor Brian Greene has become the closest thing that physics has to a pop star. A Harvard grad and former Rhodes scholar, lured in 1996 from a professorship at Cornell to a tenured position at Columbia, he has emerged as the chief ambassador of string theory, bringing cutting-edge work to the public in a series of TV appearances and lectures around the globe. His celebrity can be attributed to a widespread popular appetite for avant-garde science dressed in neat metaphorical packages: The universe is elegant; the cosmos is like a string symphony. Yet there is plenty to be suspicious of in Greene's unself-conscious romanticism—his unnuanced use of terms like elegance and beauty—and his teleological approach to the history of physics. Where, exactly, does he stand in the pantheon of physicists?Greene may be treated as a kind of New Age, scientific guru by the public, but scientists disagree about the significance of his scholarly work. Each time Greene is featured or reviewed on television or in a magazine, one of string theory's aged, cranky critics is trotted out to offer harsh assessments. (These seem to have had no impact on the public's fascination.) In the NOVA special, Nobel laureate Sheldon Glashow drove home the obvious but downplayed fact that string theory has not been—and may never be—experimentally verified, and that it may be more philosophy than physics. More recently, in the New York Review of Books, Freeman Dyson, an octogenarian and self-proclaimed "old conservative, out of touch with the new ideas," suggested that string theory may simply be one of history's "fashionable" ideas, the kind that flourish briefly, then forever fade away.
If we're going to hold the teleological and philosophical nature of theories against them there won't be anything left of science. Posted by Orrin Judd at July 10, 2004 4:20 PM
The more interesting question is why they continue to feed at the public teat?

Posted by: Annoying Old Guy at July 10, 2004 8:11 PMUnfortunately not away from schoolchildren, who they pump this science guff into.

Oh, the ironies of people using their computers to gripe about science!
(And no, don't tell me computers are simply engineering: transistor and silicon chip development required lots of physics.)
Posted by: PapayaSF at July 10, 2004 10:09 PMOnce we understand that we can't experience or comprehend reality directly, we understand that all human knowledge is metaphor.
Posted by: David Cohen at July 10, 2004 10:15 PMWhat I love is the direct quote "In fact, given its unprovability, it might be "permanently safe" (Glashow again) from meaningful refutation."
And this is different from Religion how?

"Oh, the ironies of people using their computers to gripe about science!"
What he said.
String theory isn't testable yet not because it makes no testable predictions, but because it requires levels of experimental energy that we don't yet know how to handle in the lab. It's tendentious to assume that because in 2004 we can't yet settle its validity, that we never will.
String theory is highly worth thinking about because it is one of very few physical theories we have that offers even the possibility of reconciling quantum mechanics (which we know is experimentally validated, but incomplete) and general relativity (which we also know is validated but incomplete). The point is not that it is the only such theory or that it should be accepted as dogma without experimental evidence, but that working scientists earn their paychecks by *working*: and when you have two partial theories, working means spending a lot of time and energy figuring out how to reconcile them.

Posted by: Erich Schwarz at July 11, 2004 4:27 AMThe problem with String Theory is that it is unfalsifiable. Whenever the theory diverges from percieved reality, they just add another folded dimension.

By doubt the scientific mean only doubt about your religion, not theirs.

Posted by: Harry Eagar at July 11, 2004 1:59 PMWell, it's false, so it can only be describing what the theorist desires.
Posted by: oj at July 11, 2004 2:05 PMoj,
No, we "scientific" do indeed mean doubt about our scientific work. That's why it's possible to have a rational argument about whether string theory is valid or not, and why a fair number of physicists don't agree with string theory (or at least don't see it as an effective project in 2004 A.D.)
If you want to see what a society looks like that doesn't have us "scientific" dissidents in it, just look at the Muslim world. No Brian Greenes *there*. The Muslims made up their minds long ago about the pointlessness of human efforts to rationally understand objective reality. Observe the consequences, and ask yourself if you really want to see those annoying scientists stop their work.
"Science, also, must be divorced from curiosity. The business of science, [Tolstoy] says, is not to discover what happens, but to teach men how they ought to live. So also with history and politics. Many problems (for example, the Dreyfus Case) are simply not worth solving, and he is willing to leave them as loose ends. Indeed his whole theory of 'crazes' or 'epidemic suggestions', in which he lumps together such things as the Crusades and the Dutch passion of tulip growing, shows a willingness to regard many human activities as mere ant-like rushings to and fro, inexplicable and uninteresting. Clearly he could have no patience with a chaotic, detailed, discursive writer like Shakespeare. His reaction is that of an irritable old man who is being pestered by a noisy child. 'Why do you keep jumping up and down like that? Why can't you sit still like I do?' In a way the old man is in the right, but the trouble is that the child has a feeling in its limbs which the old man has lost. And if the old man knows of the existence of this feeling, the effect is merely to increase his irritation: he would make children senile, if he could."
--George Orwell, _Lear, Tolstoy, and the Fool_

Posted by: oj at July 11, 2004 2:58 PMWhat is, then, the true statement about what the Second Law treats?
Posted by: Harry Eagar at July 11, 2004 4:32 PMSome things are entropic
Posted by: oj at July 11, 2004 4:38 PMI am just not in favor of throwing money a problems nobody has the vaguest idea of solving.
Posted by: Robert Schwartz at July 11, 2004 10:04 PMWhich things are not?
Posted by: Harry Eagar at July 12, 2004 2:18 PMThose which intelligence chooses to intervene in.
Posted by: oj at July 12, 2004 2:33 PMAccording to you, that's everything.
Yet the Second Law works everywhere we look.

Posted by: oj at July 13, 2004 12:24 AMOJ seems to have real problems with the concept of a closed system.
The Earth is not a closed system.
Never mind problems with organization. Life is no more organized now than 300 million years ago.

Posted by: oj at July 13, 2004 8:33 AMOr, as Lynn Margulies put it, wherever there is one photon available to be exploited, life will find it and exploit it.
But life does not create the photons.
How often your habit of induction forces you to make absurd statements that even you would not dare to act on.
Posted by: Harry Eagar at July 13, 2004 2:04 PMYet photons were Created
Posted by: oj at July 13, 2004 2:52 PMOJ:
And the eye saw 300 million years ago, too. Every bit as well as eyes see now.
Oddly, considering another related thread, your capital Created suggests you have certain knowledge of how photons came to be.
