Killing the king
Here is a story from Felix Frankfurter Reminisces (1960):
On Oliver Wendell Holmes, Jr. and Ralph Waldo Emerson, p. 59.Likewise, critcisms of Pres. Barack Obama have to show that he is unfit for the office, or they do no real damage. The birth certificate had to show that he was not an American, or else it is insignificant.
Info about Obama's past does tell us more about who he is. His decisions as President continue to baffle those on the right and the left. We know less about him than we do about any American president in decades. His parents are dead. He has little contact with family and friends. We knew Bush, McCain, Kerry, Gore, Clinton, Dole, etc. much better.

Max Born on Einstein
It is easy to find glowing praise for Einstein's famous 1905 paper. Max Born wrote:
A long time before I read Einstein’s famous 1905 paper, I knew the formal mathematical side of the special theory of relativity through my teacher Hermann Minkowski. Even so, Einstein’s paper was a revelation to me which had a stronger influence on my thinking than any other scientific experience… Einstein’s simple consideration, by which he disclosed the epistemological root of the problem… made an enormous impression, and I think it right that the principle of relativity is connected with his name, though Lorentz and Poincare should not be forgotten.But no one said anything so ridiculous (publicly) during 1905-1908. The most credit Einstein ever got was to have relativity called the "Lorentz-Einstein" theory.
The Born story is told a little differently in Einstein: the life and times By Ronald W. Clark. There seem to be some inconsistencies in the stories Born told about learning relativity.
Born's 1921 book on "Einstein's Theory of Relativity" said:
Only the reader who has made this view really his own will be able to folow the later development of the doctrine of space and time. Different people find progressive abstraction, objectivation, and relativization easy or difficult, as the case may be. The older peoples of the Continent, Dutch, French, Germans, Italians, Scandinavians, are most susceptible to these ideas, are the most deeply engaged in elaborating this system. Englishmen, who incline to concrete ideas, are less readily accessible. Americans are fond of attaching themselves to pictures and models. [p.190-191]He later wrote to Einstein:
It is my belief that when average people try to get hold of the laws of nature by thinking alone, the result is pure rubbish.Born, who was considered Jewish by Nazi Germany because of his ancestry, also wrote privately about Jewish physics:
Ohanian (who may be Jewish himself) gives the background to this phrase ("Einstein's Mistakes" p. 97). He first attributes it to Sommerfeld (an admirer of Einstein), who wrote (approvingly) of "the conceptually abstract nature of the Semite". Ohanian goes on to interpret this remark repeating the wide-spread view (at that time) that "Jews are intellectually inventive & inclined to abstruse, convoluted arguments". Max Born (another Jewish physicist & very good friend of Einstein) described Jewish physics as "an attempt to find the laws of nature just by thinking". Einstein agreed with him when he wrote to Born "I am confident that 'Jewish physics' is not to be killed." To which, Born replied "I have always appreciated your good Jewish physics". All of these quotes are referenced in the text.The book also says that Sommerfeld complained about Einstein's "nonconstructive and nonvisualizable dogmatics", and it says that the comments were "on target".
My problem with this is that Born's 1921 book shows only a limited understanding of relativity. He says very little about electromagnetism or gravity. He does not mention covariance or recognize the concept. It is central to both special and general relativity. I realize that he got a Nobel Prize for quantum mechanics, but I am unimpressed with his relativity.
It is wrong to say that Einstein "disclosed the epistemological root of the problem". You cannot get to the root of the problem without covariance. Covariance is what makes electromagnetism a spacetime theory. Einstein did not have a spacetime theory. Born credits Minkowski for making it a spacetime theory, and describes the spacetime metric, but does not explain that physical quantities are transformed by purely geometric considerations.
My other problem with Born is that he is emphatic about crediting his friend Einstein for relativity, but he admits that it is possible that Poincare had it all first, in a 1969 essay in the book Physics in my Generation:
The reasoning used by Poincaré was just the same as that which Einstein introduced in his paper of 1905 … Does this mean that Poincaré knew all this before Einstein? It is possible … [Einstein's paper] gives you the impression of quite a new venture. But that is, of course, as I have tried to explain, not true.I don't know what to make of this Jewish physics stuff. The term seems to be mostly used in connection with German physics, and various Nazi controversies in the 1930s. Germany dominated physics at the time, and according to Wikipedia, the Jewish physics presented an excuse to resist an ideologically unwelcome scientific "paradigm shift". Some of this was aimed at relativity, as you can read in Criticism of relativity theory.
Jewish physics also relates to various ethnic stereotypes. The Half Sigma blog writes:
Both Jains and Jews are tiny minority religion with onerous dietary rules and other restrictions on the enjoyment of life, and both have disproportionate economic success. This leads me to a new theory of why Jews evolved to be smarter than gentile whites. It has to do with the religion sucking really bad. You would think that this would work in the opposite manner. A really smart Jew or Jain would realize how dumb it is that they can’t eat any good foods, and they would be the most likely to jump ship. But such thinking would be based on a misunderstanding of the psychology of high-IQ people. The higher a person’s IQ, the more they follow the rules they are taught. Within the orthodox Jewish or Jain subcultures, the moral thing to do is obey the rules of the religion. It’s the least intelligent Jews or Jains who are most likely to be tempted by the forbidden joys of tasty food and stray from the religion. In this manner, over the centuries, the least intelligent Jews and Jains are most likely to have been culled from the religions’ gene pools.I guess the idea is that Jewish rabbis are fond of arcane, tricky reasoning about artificially imposed rules that have no obvious relevance to real-world purposes, and that Jews are accustomed to admiring that. The religious Jews stick to the Talmud and religious reasoning, but the non-religious Jews try to apply the reasoning elsewhere.
The Paradigm shift was popularized by a man named Kuhn. That is often a Jewish name, and often not. I don't know whether he was Jewish or not. There are lots of Jews and non-Jews on different sides of the issues.

Why science is the source of all progress
David Deutsch David Deutsch is plugging a new book with this:
What is the secret of science's success in understanding our world? It's to do with the quality of its explanations – though there is a twist in the taleHis previous book was filled with speculative opinions about how the universe. This one seems to be a continuation.
I am skeptical about the importance of "rebellions against authority" to the history of science. Most of the great advances of science had the explicity approval of the authorities, as far as I know. I guess I will have to read the book to find out.
The New Yorker also has an article about Deutsch.
David Deutsch, who believes in multiple universes and has conceived of an as yet unbuildable computer to test their existence. ...I bet that none of this ever happens. He has a wrong idea of quantum mechanics.

The evolutionist split on religion
The leftist-atheist-evolutionists have split into two factions. There are the new/gnu atheists (like Dawkins, Coyne, Myers, Hitchens) who hate all religion and view the Darwinist cause as inseparable from the effort to stamp out religion. And there are the accommodationists (like Scott, NCSE, BCSE, Mooney) who insist on saying that some religions are better than others, and who try to make allies with the ones who accept evolutionism.
Eg, Myers and Coyne rant here.
It seems to me that all of the prominent evolutionists have some sort of disease where they cannot stop picking fights over religion. I think that it ought to be possible to teach evolution in school without picking fights with Christianity, but the evolutionists cannot be trusted to do it. They insist on attacking the fundamentalists, and then arguing about whether all Christians must be attacked.
I could understand if the evolutionists wanted to speak out against Islam. Prominent Moslems receive death threats if they support evolution. But fundamentalist Christians do not go around killing people for their beliefs.

Einstein on the aether
Here is how Einstein described Lorentz's belief in the aether:
In view of his unqualified adherence to the atomic theory of matter, Lorentz felt unable to regard the latter as the seat of continuous electromagnetic fields. He thus conceived of these fields as being conditions of the aether, which was regarded as continuous. Lorentz considered the aether to be intrinsically independent of matter, both from a mechanical and a physical point of view. The aether did not take part in the motions of matter, and a reciprocity between aether and matter could be assumed only in so far as the latter was considered to be the carrier of attached electrical charges.This is from A Brief Outline of the Development of the Theory of Relativity (1921), by Albert Einstein, translated by Robert William Lawson, Nature, 106 (No. 2677); February 17, 1921; pp. 782-784.
All of this seems correct to me. It is widely believed that Einstein invented relativity by abolishing the aether that Lorentz foolishly believed in. But in fact Lorentz's beliefs were completely reasonable, and Einstein never disputed them.

Oppenheimer was crazy
A Wikipedia article about J. Robert Oppenheimer drew this comment:
''In the fall of 1925, Oppenheimer poisoned an apple with chemicals from the laboratory and put it on Blackett's desk ... As Robert's parents were still visiting Cambridge, the university authorities immediately informed them of what had happened. Julius Oppenheimer frantically - and successfully - lobbied the university not to press criminal charges. After protracted negotiations, it was agreed that Robert would be put on probation and have regular sessions with a prominent Harley Street psychiatrist in London. This Freudian analyst diagnosed dementia praecox, a now archaic label for symptoms associated with schizophrenia. He concluded that Oppenheimer was a hopeless case and that "further analysis would do more harm than good".''Needlessly besmirches JRO's reputation? Read the rest of the article. He was a no-good commie with an assortment of character defects. His reputation is only propped up thru the work of commie sympathizers.

42 Nobelists oppose teaching critical thinking skills
The Wash. Post reports:
A 17-year-old Baton Rouge high school senior is leading the fight to repeal a Lousiana law that gives teachers license to equate creationism with evolution -- and now he is doing it with the support of more than 40 Nobel laureates.Zack Kopplin's letter and 42 Nobel prizewinners are here. Only 8 of them got prizes in physiology or medicine, and only about half of them are American. The letter says:
As Nobel Laureates in various scientific fields, we urge you to repeal the misnamed and misguided Louisiana Science Education Act (LSEA) of 2008. This law creates a pathway for creationism and other forms of non-scientific instruction to be taught in public school science classrooms. ...So why are physicists, chemists, and foreigners expressing an opinion about fighting HIV and growing plants? This is way out of their expertise. You must be thinking that the La. law is really terrible.
Here is the official description of the bill to repeal the LSEA:
Present law, the "Louisiana Science Education Act," requires BESE, upon request of a local school board, to allow and assist teachers, principals, and other school administrators to create and foster an environment within public elementary and secondary schools that promotes critical thinking skills, logical analysis, and open and objective discussion of scientific theories being studied including evolution, the origins of life, global warming, and human cloning.I do not see the problem with the LSEA. It does not promote creationism, religion, or supernatural beliefs. It only supports the "open and objective discussion of scientific theories". No real scientist should be afraid of that. So why are so many agitated about this harmless law, if no religion is involved?
It appears that the evolutionists want to force the schools to teach that evolution explains all life on Earth, and to prevent them from teaching that there is very little scientific knowledge about the origin of life.
This is crazy. Science classes should teach the limits of scientific knowledge. The Noble prizewinners have taken a very anti-science position.
Tennessee is considering a similar law to the LSEA.

MacDonald on Einstein
A recent Christian blog post has been criticized for being anti-Jewish for comments like this:
Further reading of MacDonald’s The Culture of Critique extensively documents the academic fraud of Freud, Boas and the Frankfurt School (especially the “authoritarian personality” studies). All of these movements were led by Jews who expressly saw their work as an attack on the West, particularly Christianity, on behalf of Jews. MacDonald goes through pains to document this with their own words, that they were not Leftists who “happen to be” Jews, but rather Leftists who saw their Jewish identity as an integral motivation and justification for their work.This refers to Kevin B. MacDonald, a California professor who wrote some controversial books Jews and group strategies.
I am skeptical about evolutionary psychology, so I would not take this too seriously. MacDonald seems to carefully document everything he says, but that does not mean that he is necessarily right. He has been widely criticized for discussing a taboo subject, as explained at the above links. Some of his more outrageous claims are listed here, such as:
(7) who suggests that European-Jewish intellectual prominence is genetically based and the result of eugenic processes within traditional Jewish communities; (8) who argues that Jewish intellectuals such as Franz Boas, Felix Frankfurter, Harold Laski, Max Lerner, Morris Cohen, and Robert Merton, accelerated the 'deChristianization' of America's public life by selectively promoting as cultural heroes Gentiles who advanced their goals, such as Margaret Mead, John Dewey, and Justice Oliver Wendell Holmes; (9) who agrees with T. S. Eliot's most famous anti-Semitic statement, that any large number of free-thinking Jews is undesirable if one wants to maintain or develop a society in which a Christian, ethnically homogeneous tradition can flourish.MacDonald has a theory about 20th century Jewish intellectuals, but he says that Einstein does not fit in:
Similarly, 20th-century theoretical physics does not qualify as a Jewish intellectual movement precisely because it was good science and there are no signs of ethnic involvement in its creation: Jewish identification and pursuit of Jewish interests were not important to the content of the theories or to the conduct of the intellectual movement. Yet Jews have been heavily overrepresented among the ranks of theoretical physicists.The references are to Albert Einstein: A Biography, by the German physics journalist Albrecht Fölsing, an Einstein idolizer.
That is, the theory of relativity is not a theory designed to promote Jewish interests. I assume that MacDonald knows about the criticism of relativity theory, where some people tried to relate relativity to Jews, particularly during the Nazi era. Apparently some were proponents of the so called German Physics, which only accepted scientific knowledge based on experiments, and which is accessible to the senses. They preferred this to the alleged formal-dogmatic "Jewish physics", such as relativity.
According to Wikipedia, the 1931 German book, Hundred authors against Einstein, was not anti-Semitic. Opposition to relativity had very little to do with Einstein being Jewish.
MacDonald lists differences between Albert Einstein and other scholars who led unscientific movements. These differences are not so great. Relativity was scientific, but most of Einstein's later work on unified field theories was not. Einstein certainly lacked intellectual honesty and empirical rigor, as I explain in other posts. MacDonald seems to be overly impressed with the Einstein myth.
Scientific weakness is critical to MacDonald's theory, and no accuses Einstein of scientific weakness. Einstein is supposed to be the world's greatest scientist. But Einstein's scientific reputation is primarily based on his relativity work from 1905-1915. His later work on quantum mechanics, cosmology, and unified field theory was almost entirely worthless. And his relativity work is vastly overrated.
I don't know what the "obvious political and ethnic motivation" would be for either relativity or Einstein's theories. Einstein was involved in some academic battles, but I am not sure that he was always allied with Jews, and his enemies allied with non-Jews. So I am assuming that Einstein does not fit into MacDonald's theory, but I do not know enough about the subject. Someone should do a scholarly examination of this issue.

Restoring humanity's rightful place in the universe
A physicist and philosopher (husband and wife) say:
That's the picture that Santa Cruz's Nancy Ellen Abrams and Joel Primack are drawing in their new book "The New Universe and the Human Future: How a Shared Cosmology Could Transform the World." While the rest of us are paying attention to the iPad, "American Idol" and Donald Trump, Abrams and Primack are making a spectacular claim -- that the most significant moment in human history may be ... right now. ...According to them, we earthlings really are at the center of the universe.

Mooney argues that Republicans are stupid
Chris Mooney writes in a Mother Jones article:
"A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point." So wrote the celebrated Stanford University psychologist Leon Festinger (PDF), in a passage that might have been referring to climate change denial—the persistent rejection, on the part of so many Americans today, of what we know about global warming and its human causes. ...Mooney's examples are not very convincing. It just seems like elaborate name-calling for people with a political disagreement.
For example, he starts off citing a study about people not accepting arguments about whether Pres. Obama is a Moslem.
It seems rational to me for someone to say that Obama is a Moslem, even after been told some (fictitious) quote of him denying it.
People usually attribute religion based on religion of the parents, unless there is an overt conversion or repudiation. In Obama's case, he has a Moslem name, his father and step-father were Moslems, he lived as a kid in Moslem country, he claims that he belonged to a Christian church in Chicago but seemed to have very little knowledge of what went on there, he goes out of his way to praise Islam, such as saying that the Koran is a holy book, his profession of Christianity is particularly unconvincing compared to other presidents, and we normally discount self-serving claims from politicians.
So I don't think that the Obama study really shows that people refuse to accept facts. It assumes that we are supposed to accept some politician's description of his own beliefs. Some people do and some don't. If a Jewish politician suddenly announced that he was not a Jew, some people would still call him a Jew. They are not stupid; they just define Jew differently.

Free Lorentz essay on Kindle
An Amazon review of Lorentz's 1920 relativity book begins:
Albert Einstein is rightly considered one of the greatest scientists of all time, and his two theories of relativity - special and general - are the crowning glory of his scientific oeuvre. They have fundamentally reshaped our thinking of the most fundamental concepts - space, time and matter. These two theories have also withstood the test of time, and a century after they had been formulated they are still almost entirely used in their original formulations.The review drew this reply:
Chauncey Zalkin writes: one of the? i'm asking without sarcasm here because this is not my field but wasn't he the greatest scientist of all time?Apparently people are so accustomed to over-the-top praise for Einstein that anything less is considered an insult.
Only the free Kindle edition of this book gets gushing reviews, while the $4 paperback it is really just a poor reproduction of a short essay in the public domain. It is easily found online as The Einstein Theory of Relativity by Hendrik Lorentz.
The forward recites the myth of the 12 men:
WHETHER it is true or not that not more than twelve persons in all the world are able to understand Einstein's Theory, it is nevertheless a fact that there is a constant demand for information about this much-debated topic of relativity.Lorentz says that the difficulty is exaggerated:
I cannot refrain, while I am mentioning it, from expressing my surprise that, according to the report in The Times, there should be so much complaint about the difficulty of understanding the new theory. It is evident that Einstein's little book "About the Special and the General Theory of Relativity in Plain Terms," did not find its way into England during wartime. Any one reading it will, in my opinion, come to the conclusion that the basic ideas of the theory are really clear and simple; ...That's right. The theory of quantum mechanics turned out to be much more difficult to understand.
Leakey on human evolution
Famed African paleontologist Richard Leakey was just interviewed on NPR Science Friday. Leakey says that man is an ape, and:
People didn't like the idea that the world was not at the center of the universe. People didn't like the idea that the world wasn't flat. Given time and evidence, people have learned to accept these things if they are true, and I think that there is no question about the truth of human evolution, none at all. [at 26:25]Leakey also said that he has doubted that Lucy was a human ancestor, even tho that is claimed by other big-shots.
It is amusing that whenever a scientist wants you to believe something just because others scientists say so, he frequents makes some silly comparison to the Myth of the Flat Earth or Geocentrism. Both, in this case.
It is a big myth that people didn't like those ideas. Scientists discredit themselves when they give such phony arguments, and act as if they are common knowledge.
In Leakey's case, someone could argue that Leakey himself just didn't like the idea of being a descent of a small-brain ape like Lucy.

Galison on Einstein thinking pure thoughts
Harvard historian Peter Galison writes in 2003:
The Einstein we know today is mostly based on Einstein’s later years, when he prided himself on his alienation from practically everything sociable and human, projecting an image of himself as a distracted, other-worldly character. We remember that Einstein who said that the best thing for a theoretical physicist would be to tend a lighthouse in quiet isolation from the world in order to be able to think pure thoughts. We have this picture of the theoretical physicist, and project it backwards to Einstein’s miraculous year, 1905. It is easy enough to think of him as working a day job in a patent office merely to keep body and soul together, while in actuality his real work was purely cerebral.Yes, Einstein projected that image, but no progress in physics was ever accomplished that way.
Galison goes on to say:
Poincaré and Einstein, who had two of the largest scientific correspondences of the 19th and 20th centuries, including thousands of letters to and from other people, never exchanged a single postcard over the entirety of their overlapping lives. They met once, towards the end of Poincaré’s life, when Poincaré presided over a session at a vitally important physics conference where Einstein was talking about his new ideas about the quantum of light. At the end of this session, Poincaré said that Einstein’s presentation was so different from what physics should be — namely that it could be represented with causal interactions, with good differential equations, with clear presentations of principles and consequences — that he simply found it unbearable, and ended by making it clear that what Einstein was saying was so contradictory that anything could follow from it. It was a disaster for science, he thought. Einstein for his part went home and scribbled a note to a friend in which he recounted the wonderful work that had been done by various colleagues, how much he admired, even loved, the physicist Hendrik Lorentz, but disparaged Poincaré who simply seemed to understand nothing. The passed like ships in the night, each, on relativity, unable to acknowledge the other’s existence.Causality was a major factor in Poincare formulating his theory of relativity, and I am not sure that Einstein ever understood it. I would not be surprised if Poincare had a low opinion of Einstein.

Bohr compares himself to Bruno
From a Niels Bohr interview in 1962:
So, therefore, the relationship between scientists and, philosophers was of a very curious kind. First of all I would say — and that is the difficulty — that it is hopeless to have any kind of understanding between scientists and philosophers directly. It has to go over the school. I don't know exactly how it is, but let us say, if you go back to ... the Copernican system, then some scientists they thought that it also was beautiful. But they were killed. Bruno was absolutely killed, and Galilei was forced to recant. But in the next generation, the school-children did not think it was so bad, and thereby a situation was created where it belonged to common knowledge or common preparation that one had to take that into account. I think it will be exactly the same with the complementary description.Exactly the same? Who was killed over Complementarity?
It is true that physicists have debated Wave–particle duality for centuries, and many, such as Einstein, did not accept it. Some still don't.
Giordano Bruno was a Catholic monk who was burned at the stake for stubbornly denying the divinity of Jesus Christ. The closest he got to science was to speculate that there could be crucifixions on other worlds.
Bohr was brilliant, but he could be incoherent at times.

Tegmark on teleportation
In the podcast for this 2008 NY Times article about teleportation in the movies, MIT physicist Max Tegmark says:
It is very important to realize that even tho it might sound totally useless to think about fundamental physics questions like how space and time work. It was precisely because Einstein was thinking about the nature of time that he figured out that mass equals energy times the speed of light squared, and this gave us nuclear power. [at 5:10]No, that is all wrong. Even the formula is wrong.
What he says about quantum teleportation is even worse. He praises Quantum cryptography and Quantum computation as if these had proven validity. They do not, as noted below.

Stories about Professor Paradigm
Errol Morris is a filmmaker whose movie “The Fog of War: Eleven Lessons From the Life of Robert S. McNamara” won the Academy Award for best documentary feature in 2004tells this story about famous Princeton philosopher Thomas Kuhn:
It was April, 1972. The Institute for Advanced Study in Princeton, N. J. The home in the 1950s of Albert Einstein and Kurt Gödel. Thomas Kuhn, the author of “The Structure of Scientific Revolutions” and the father of the paradigm shift, threw an ashtray at my head. ...For that he got kicked out of Princeton philosophy grad school. (In fairness, Kuhn's daughter denies the ashtray story in a comment. Maybe Kuhn wasn't trying to hit Morris, but Morris says that it was thrown at his head.)
Statistics professor A. Gelman tells this:
I was looking through the course catalog one day and saw that Thomas Kuhn was teaching a class in the philosophy of science. Thomas Kuhn -- wow! So I enrolled in the class. I only sat through one session before dropping it, though. Kuhn just stood up there and mumbled.Morris continues to rip Kuhn:
As John Burgess, a professor of philosophy at Princeton, told me in an interview: “Kuhn speaks one way when speaking to historians, and another way when speaking to philosophers. The trouble begins when he starts talking about things being socially constructed. ..."The trouble begins when anyone starts talking about things being socially constructed. It is the first sign of a reality-denier.
Steven Weinberg has written eloquently in The New York Review of Books about Kuhn and paradigm shifts. A Nobel Prize-winning physicist was outlining the difference between “Kuhnian science” (that is, science as Kuhn imagined it) and actual science. And argued that Kuhn’s theories did not characterize science as Weinberg knew it. Weinberg wrote, “What does bother me on rereading Structure and some of Kuhn’s later writings is his radically skeptical conclusions about what is accomplished in the work of science…conclusions that have made Kuhn a hero to the philosophers, historians, sociologists, and cultural critics who question the objective character of scientific knowledge, and who prefer to describe scientific theories as social constructions, not so different from democracy or baseball.”Yes, that is right. Weinberg's article is here, with excerpts here. Somebody does need to drive that stake through the heart of the vampire. Kuhn is dead, but his followers dominate academic philosophy and their views are even more ridiculous. The vampire is the academic anti-science view of science.

Tennessee favors science
The Bad Astronomer says:
A bill clearly intended to promote and protect antiscience passed in the Tennessee State House yesterday, by a vote of 70 – 23.The bill says:
Toward this end, teachers shall be permitted to help students understand, analyze, critique, and review in an objective manner the scientific strengths and scientific weaknesses of existing scientific theories covered in the course being taught. ...This bill is pro-science, not anti-science. Learning science always means learning the strengths and weaknesses of the theories. It ought to, anyway.
I have become convinced that the real anti-science folks in our society are scientists like the Bad Astronomer who try to force their bad science on the rest of us.

Hamming on mathematical physics
James Gleick has a new book, The Information: A History, a Theory, a Flood. One of the famous information theorists is R. W. Hamming . He wrote in 1980:
The fundamental role of invariance is stressed by Wigner. It is basic to much of mathematics as well as to science. It was the lack of invariance of Newton's equations (the need for an absolute frame of reference for velocities) that drove Lorentz, Fitzgerald, Poincare, and Einstein to the special theory of relativity. ...Of course Einstein knew in advance what the theory looks like. It had been published by Lorentz and Poincare! It already had been experimentally confirmed, and Lorentz received the Nobel Prize. Einstein did not even need to learn about the details of the experiments; he just had to write up the Lorentz-Poincare theory.
There is more discussion of the applicability of mathematics on the article on Wigner's Puzzle.

More on Darwinian epicycles
I mentioned the group/kin selection controversy in evolutionism last year and last month
In the Aug. 26 Nature, Wilson and two Harvard colleagues argue that the concept of kin selection is “limited” and “unnecessary.” And they propose steps for the evolution of ants, honeybees and other highly social species with such altruistic behaviors by just the broad “survival of the fittest” forces of natural selection without specifically invoking the power of kinship.Ptolemy lived in Egypt, in around AD 0150. He was not a Babylonian. The Babylonians did not have the invention of geometry, and are not known to have used epicycles. Putting the Sun in the center does not eliminate the need for epicycles.
Saying that the world is simpler without epicycles is like saying that the atmosphere is simpler without clouds.
The Rousset and Leon rebuttal says:
When they ask falsely evident rhetorical questions,1 liken inclusive fitness theory to geocentrism, or claim without justification that their approach is ‘common sense’ (their Appendix, p. 20), NTW are a long way away from what is generally expected of scientific discourse. In particular, it is troubling to see the authors turn to the argument of geocentrism and its unfalsifiable epicycles to discredit inclusive fitness (their Appendix).Both sides of this debate are scientifically illiterate. There is nothing wrong with using a common sense argument that unfalsifiable features are an unnecessary complication. Except that is not really what epicycles were.
Apparently the phrase ‘Darwinian epicycles’ hit a nerve. The kin selection advocates do not think that such dispectful language should have been allowed into a journal like Nature.
Here is what Nowak el al say in their Nature supplement:
Inclusive fitness is just another method of accounting. The fact that an inclusive fitness calculation works for a particular model does not necessarily imply that ‘kin selection is at work’. ...No, the ptolemaic epicycles did not become superfluous under Newtonian mechanics. They got identified with the Earth's orbit, in the cases of Mars, Jupiter, and Saturn. For Venus, Mercury, and the Moon, they are used for the orbits of those bodies.
Here is more complete quote from the kin selection folks. It is unusually nasty. I cannot explain why people hate E. O. Wilson so much. Once someone dumped a pitcher of water on him at conference.
Nowak, M.A. et al. (2010) The evolution of eusociality. Nature, 466, 1057-1062.No, the Earth's rotation has nothing to do with the coincidences; it is the Earth's revolution about the Sun that gives the coincidence between the Mars and Jupiter epicycles. Kepler did not lay the epicycles to rest, as they are logical equivalencies in heliocentrism (as Poincare emphasized). What Kepler did do was to show that the Mars and Jupiter epicycles were really the same and not a coincidence. The epicycles have nothing to do with elliptical orbits. It appears that these authors are agreeing that Hamilton's Rule is like the geocentric epicycles, but they are all hopelessly confused about what that means.

Gould defines a fact
In connection with the Kansas evolution controversy, I ran across this 1999 Stephen Jay Gould op-ed in Time magazine:
Second, evolution is as well documented as any phenomenon in science, as strongly as the earth's revolution around the sun rather than vice versa. In this sense, we can call evolution a "fact." (Science does not deal in certainty, so "fact" can only mean a proposition affirmed to such a high degree that it would be perverse to withhold one's provisional assent.)I really disagree with this. First, evolution is a theory that includes some facts, such as gene frequencies varying from one generation to the next, and hypotheses, such as a universal common ancestor. The theory is certainly not a fact.
Second, the Earth's motion depends on the frame of reference, and is not a fact according to relativity theory.
Third, by comparing evolution to something that is demonstrably a subjective opinion, he undermine his whole argument for teaching standards that forbid an alternative view to evolution. He effectively concedes that science depends on your point of view.
Fourth, science does deal in certainty. His definition of a "fact" is bizarre.
Gould died in 2002, but in 2000 he was elected president of the AAAS and leading the charge to tell Kansas how evolution should be taught.
Gould also argues:
Should I believe Julius Caesar ever existed? The hard bony evidence for human evolution, as described in the preceding pages, surely exceeds our reliable documentation of Caesar's life.That is true, but irrelevant. Nobody cares about Caesar. If it turned out that Caesar did not exist, and maybe the historical accounts of him were really a composite of two other men, it would not affect our knowledge or worldview in any significant way.
OTOH, some people believe that evolution contradicts religion, and that would affect a lot of people, if accepted.
Gould goes on:
Third, no factual discovery of science (statements about how nature "is") can, in principle, lead us to ethical conclusions (how we "ought" to behave) or to convictions about intrinsic meaning (the "purpose" of our lives).I doubt that very many people believe this, on either side of the evolution debate.

Religion prize goes to atheist multiverse believer
LONDON, APRIL 6 – Martin J. Rees, a theoretical astrophysicist whose profound insights on the cosmos have provoked vital questions that speak to humanity’s highest hopes and worst fears, has won the 2011 Templeton Prize.Woit says:
Rees does seem to believe in something that the Templeton people are willing to take as a replacement for belief in God: belief in the Multiverse. He has been one of the leading figures promoting the Multiverse and anthropic explanations, even before the recent string theory landscape pseudo-science made this so popular.He is also a global warming alarmist.
Leftist-atheist-evolutionist Jerry Coynes calls the prize a travesty because "Templeton's mission is a serious corruption of science." and because it promotes a dialogue between science and faith. Rees says that he is not religious, but I guess that he is not atheist enough for Coyne.

New attempts to verify quantum mechanics
AAAS Science magazine (Science 18 March 2011) has an article on Quantum Mechanics Braces for the Ultimate Test. It tries to justify Quantum cryptography by doing experiments to close Loopholes in Bell test experiments. Previous experiments have fallen short, as explained in the 2004 paper, Bell's theorem and the experiments: Increasing empirical support to local realism.
I think that this research is based on a profound misunderstanding of both quantum mechanics and cryptography. No useful results will come of it.
Abner Shimony gives a conventional explanation of Bell's Theorem.
Discussion of whether the Principle of locality (or Non-locality) can be consistent with the Interpretation of quantum mechanics is discussed in these recent papers: The EPR paradox, Bell's inequality, and the question of locality by Guy Blaylock, and EPR, Bell, and Quantum Locality by Robert B. Griffiths. If these papers are correct, then a lot of popular explanations of quantum mechanics are wrong. Some of these points are also explained by Lubos Motl's Delayed choice quantum eraser.
The problem with quantum cryptography is that it claims to use proven physics to solve a cryptographic problem. However, it does not do anything cryptographical useful because it cannot use a convention communication channel like the internet, and it cannot authenticate messages.
It also does not use proven physics. Many aspects of quantum mechanics have been proven by very convincing experiments, but not the features that are needed for quantum cryptography. As the above article explains, all those necessary arguments have loopholes, and no one has been able to close the loopholes. The article quotes researchers claiming that the loopholes will be closed any day, but they have been claiming that for 40 years. There are laws of physics that suggest that those laws will never be closed.
The AAAS Science does not explain these controversies, or why there are good reasons to believe that the quoted researchers are pursuing a dead end. Popular explanations of these subjects almost never get it right.

Boy smarter than Einstein
The UK Daily Mail says: Autistic boy,12, with higher IQ than Einstein develops his own theory of relativity, and Time magazine says: 12-Year-Old Genius Expands Einstein's Theory of Relativity, Thinks He Can Prove It Wrong.
A 12-year-old child prodigy has astounded university professors after grappling with some of the most advanced concepts in mathematics.The video is gibberish, of course. It looks as tho he is playing a joke on naive reporters.

Fictional plot to kill Copernicus
I just saw Lawrence Goldstone on C-SPAN2 Book-TV promoting his 2010 book, The Astronomer: A Novel of Suspense. It is about a fictional 1534 Christian plot to kill Copernicus before he can publish his ideas about the Earth's motion.
One reviewer says that he got suspicious of the factual background when the characters ate potatoes! Potatoes were a New World food that had not yet spread to Europe. Another says that he teaches the Scientific Revolution, and was excited by the realism.
No, the book is not realistic. The Catholic Church had no quarrel with Copernicus when he published his 1534 book, and has never opposed the publication of scientific ideas. It certainly did not hire killers to murder scientists.
Goldstone is a Jewish name, and this is a bigoted anti-Christian book. I wonder how people would react if someone with a Christian name wrote a book claiming to be a historical novel about how Jews drank the blood of Christian babies, or some such nonsense.

Turtles all the way down
A variant of the Myth of the Flat Earth is the myth that the Earth is held up by turtles. The Evolving Thoughts blog tells this old story:
One day when the philosopher William James, who had a liking for scientific popularization, had just finished explaining in a small American town how the earth revolved around the sun, he saw, according to the anecdote, an elderly lady approaching with a determined look. Apparently, she strongly disagreed, expressing herself in the following terms: no, the earth does not move, because, as is well known, it sits on the back of a turtle. James decided to be polite and asked what, according to the hypothesis, the turtle rested on. The old lady replied without hesitating” But on another turtle, of course.” And James persisted: “But what does the second turtle rest on?” Then, so the story goes, the old lady triumphantly exclaimed: “It’s no use, Mr James, it’s turtles all the way down.” [From Isabelle Stenger's book, Power and Invention. However, in similar form, the story is widely found ascribed to James.]While this story is commonly used by atheists to make fun of religious believers, the original usage appears to be from an 1854 debate in which a Christian was making fun of an atheist. A comment cites this:
[at the end of night #2 of a public debate between a Christian and a skeptic of some sort in 1854]Bertrand Russell wrote, in Why I Am Not a Christian:
If everything must have a cause, then God must have a cause. If there can be anything without a cause, it may just as well be the world as God, so that there cannot be any validity in that argument. It is exactly of the same nature as the Hindu’s view, that the world rested upon an elephant and the elephant rested upon a tortoise; and when they said, “How about the tortoise?” the Indian said, “Suppose we change the subject.” [p.7]Wow, I wonder if anyone really believed these elephant and turtle myths. My guess is that it is like the flat earth and stationary earth myths, and mainly used to make fun of scientific ignorance.
A related myth is that the Earth rests on an elephant. Both seem to have occurred in various cultures. The earliest reference seems to be 1690, according to this Hindu world tortoise article:
The combination of tortoise and elephant is present in John Locke's 1690 tract An Essay Concerning Human Understanding, which references an "Indian who said the world was on an elephant which was on a tortoise".What I don't see is where any Hindus or anyone took these myths seriously. The myths seem to be repeated primarily to make fun of people. That is what Hawking does, at the beginning of his famous 1988 book, A Brief History of Time.
