Friends Don’t Let Friends Learn Probability from Yudkowsky

Suppose I said, “I have this clock that I really like. It’s a very nice clock. So, I am going to measure everything I can in terms of the times registered on this clock.”

“OK,” you might say, while wondering what the big deal is.

“In fact, I am going to measure all speeds as the time it takes to travel a standard unit of distance.”

“Uh, hold on.”

“And this means that, contrary to what you learned in Big University, zero is not a speed! Because the right way to think of speed is the time it takes to travel 1 standard distance unit, and an object that never moves never travels.”

Now, you might try to argue with me. You could try to point out all the things that my screwy definition would break. (For starters, I am throwing out everything science has learned about inertia.) You could try showing examples where scientists I have praised, like Feynman or whoever, speak of “a speed equal to zero”. When all that goes nowhere and I dig in further with every reply, you might justifiably conclude that I am high on my own supply, in love with my own status as an iconoclast. Because that is my real motivation, neither equations nor expertise will sway me.

Friends Don’t Let Friends Learn Physics From Yudkowsky

With the demise of Reddit, we have lost /r/SneerClub, the Internet’s hot spot for mocking those who proclaim allegiance to capital-R Rationality and related ideologies like longtermism. Somewhere in between the discussions of heavy stuff like sexual harassment in Effective Altruism culture and total frivolity were the rambles about science. I thought I would pull a couple such comments out of the archives and edit them into something shaped like a blog post. So, consider this your Attention Conservation Notice: if you’d rather not work through a self-admittedly rough explanation of how Eliezer Yudkowsky’s claims about quantum physics are just silly, exit now.

Yudkowsky clearly intends to argue that the scientific community is broken and his brand of Rationalism(TM) is superior, but what he’s actually done is take all the weaknesses that physicists have when discussing quantum foundations and present them in a more concentrated form. There’s the accepting whatever mathematical formulation you learn first as the ultimate truth, the reliance upon oversimplified labels and third-hand accounts rather than studying what the pioneers themselves wrote, the general unwillingness to get out of the armchair and go even so far as the library…

Colony Collapse Disorder

Bug Girl takes on a recent paper which claimed to find evidence that cell phones have it in for beehives. The punchline:

This paper (which for a student research paper would be questionable) should not have been in a journal. It definitely should not have postulated a connection to Colony Collapse Disorder.
And it should never have made the levels of press exposure that it did.

Monday BPSDB: Null Physics

BPSDBA fellow named Terry Witt has been advertising his self-published book, Our Undiscovered Universe, in places like Discover magazine and Scientific American. Unfortunately, the ad pages aren’t exactly peer-reviewed, or even cross-checked with a nearby grad student; being businesses, magazines naturally care about revenue. Upon examination, Our Undiscovered Universe turns out to be brimming over with crank physics and general nonsense. Ben Monreal, who was one of the intimidatingly smart people in the lab where I did my undergrad thesis, has weighed Witt’s “Null Physics” and found it wanting; his review of Our Undiscovered Universe is quite a good read.

Witt’s book starts with pseudomathematics before moving on to pseudophysics. As Ben explains,

Chapter 1 is where Witt lays out a series of “proofs” derived from what he calls the “Null Axiom”. That axiom is: “Existence sums to nonexistence” (pg. 28)—something that Witt calls self-evident after a page of invalid set theory. The central mistake, if I had to identify one, is the claim that “X does not exist” is the same as “everything except X exists”. This is utter baloney, whether in formal logic or in set theory or in daily experience.

Actually, as the book unfolds, Witt doesn’t appear to use this dead-in-the-water non-axiom for anything. He does, however, pile on more pseudomathematics:

Chapter 3 contains such gems as Theorem 3.1: “The Existence of Any Half of the Universe is Equal to the Nonexistence of the Other Half” (pg. 66) and Theorem 3.9: “The Time Required for Light to Traverse the Universe is Eternity, infinity/c” (pg. 72). I am not making this up. Witt throws around “infinity” as though it were an ordinary real number; he multiplies and divides by it, etc., with normal algebraic cancellation. This is complete nonsense; there are two centuries of mathematical thought figuring out the mathematical properties of infinity, and Witt’s approach is valid in exactly none of them. (Witt later explained on his online forum—currently disabled—that he’s reinvented all of the mathematics associated with “infinity”. His reasoning, if that’s what you call it, was that his new definition jibed with a grand idea about math being dependent on nature; it was an argument from incredulity.)

When Witt does finally get around to physics, five chapters into the book, he doesn’t do any better.

Quantum Woo, Part N

BPSDBTime for a little BPSDB! The redoubtable Ben Goldacre has the dirt on Bill Nelson’s “QXCI machine,” a device for “bioenergetic health auditing,” a medical procedure well-known among specialists as an essential step in the surgical removal of cash from wallets. Best of all, though, is what QXCI stands for: Quantum Xrroid Consciousness Interface. Now, quantum physics has jack to do with consciousness, but more importantly, “quantum xrroid” just sounds. . . painful. Like a blood boil growing inside your X, if you know what I mean.

Maybe a “quantum xrroid” means that your X is in a superposition of inflamed and not inflamed and only settles on one or the other option when your doctor examines it.

(Incidentally, I met the redoubtable Ben Goldacre in Vegas a few weeks ago — and thereby would hang a tale, if he weren’t still hoarding the photo evidence.)

The Strident and The Shrill

BPSDBRichard Dawkins and PZ Myers had a lengthy, informal chat during the 2008 American Atheists conference in Minneapolis, and a recording of their conversation is now available on DVD and in the video tubes. They discuss the fight against pseudoscience as well as several interesting topics in good science.

I did my best to summarize the kin-vs.-group business in this book review. Among the “glimmerings” which suggest there’s a better way to think about some evolutionary processes (name for that better way still to be defined) are, I think, the epidemiological simulations in which fitness of a genotype is clearly a function of ecology and thus strongly time-dependent, and consequently existing analysis techniques are likely to fail. Assuming this kind of thing happens in the real world, it might be better to speak of “extending the evolutionary stable strategies concept” or “temporally extended phenotypes” than to have yet another largely semantic argument over “group selection.”

Also of note:

When Dawkins spoke at the first artificial life conference in Los Alamos, New Mexico, in 1987, he delivered a paper on “The Evolution of Evolvability.” This essay argues that evolvability is a trait that can be (and has been) selected for in evolution. The ability to be genetically responsive to the environment through such a mechanism as, say, sex, has an enormous impact on one’s evolutionary fitness. Dawkins’s paper has become essential reading in the artificial life community.

Anyway, on with the show.

Antiscience in Maine

BPSDBMatthew Linkletter, a Board of Directors member of Maine’s School Administrative District 59, has been trying to squelch science education in his district. How? By throwing creationist canards at his listeners and banking on their ignorance. Reports a local Kennebec newspaper,

Linkletter suggested during last week’s SAD 59 board meeting that the board discuss evolution, the “Big Bang Theory” and other studies he believes should be deleted from the curriculum. […] Linkletter said he wants the best science for SAD 59 students, who should “be armed with the truth.” They should be able to explain the origins of life according to evolution if it is taught in the schools, he said.

“Nobody has the answer to the origins of life. It’s a philosophical question.”

OK, stop right there. First of all, the origin of life is not a “philosophical question,” but one which we can approach scientifically, and indeed have already learned a great deal about. Second, the open questions which remain about abiogenesis do not impair our ability to understand what has happened since then, in the later evolutionary history of life, any more than our limited knowledge of how humans discovered fire or invented writing affects historians’ ability to know about the American Revolution. Finally, the Big Bang is a theory like gravity is a theory — so go away now, won’t you, and try to brush up on your own science education before ruining other people’s?

Unfortunately, others are chiming in against the cause of knowledge and fact:

Expelled: The Party Game!

BPSDBSo, I emerged from my burrow wherein I had been writing my Serious Essay on the history of classical mechanics, and I discovered that Premise Media, the producers of the Expelled movie, had sent out a whiny and cranky e-mail pleading that people take groups to see their little flick. (I didn’t get the e-mail, just as I wasn’t invited to their Potemkin press conference back in March, but I’m not jealous, ’cause I received much better things in the mail recently, which I’ll be writing about soon, Isis willing.) UprightAlice points out that the message really does sound like it was composed by Mad Lib.

Basing Hopes on Pseudoscience

BPSDBOnline polls are not scientific. To state the matter more precisely, a poll on a website which is open to the entire Network and has only minimal measures to guard against repeat voting measures the people who were motivated to respond, not a representative sample of the population. Of course, it’s just like a creationist — beg pardon, a cdesign proponentsist — to rely upon a pseudoscientific tool for spurious validation of his pre-established beliefs. It is also in the nature of things that, on the Network, such attempts will backfire.

To wit, consider the poll on the Expelled! movie‘s MySpace page. The question was asked, “Do you think the theory of Intelligent Design should be taught in our education system?” The Evil Darwinismistic Conspiracy was alerted to the poll at 10:36 AM Eastern Time, and less than five hours later, this is where the results stand:

Creation, Power and Violence

The amount of hatred one can earn simply by speaking one’s mind and doing one’s job never fails to astonish me. All the more remarkable is how the people who hate so viciously are the very ones you’d expect to be tolerant, or at least quietly begrudging — people whose ancestors, both familial and ideological, were themselves the targets of bigotry in generations past, when different powers were the oppressors. Yet today, even in a country which prides itself on a long list of freedoms, speaking the plain, factual truth of the world is a sure way to win oneself ire, derision and abuse.

Both history and current events teach us that forces of prejudice and inequity oppose the dissemination of truth to certain sectors of society. As recently as 2006, the Afghan schoolteacher Mohammed Halim was drawn and quartered by motorbikes, the remains of his body put on display so that others would think twice before defying Taliban law and committing the unforgivable crime of teaching female children. I doubt the Taliban thugs who beat the algebra teachers of Ghazni have any particular animosity towards the mathematics; given a moment’s reflection, they might wholeheartedly support the math lessons necessary to train engineers who then build weapons to be used against the United States. The crime in their eyes, I’d wager, is not the material, but the audience.

In the country where I grew up and am writing now, the story is a little different: most of the time, hatred against educators does not escalate to physical violence, although threats of violence are common enough, and most of the time, the factor provoking abuse is not the audience, but the lesson itself.

The plain truth I’m talking about is the biological principle of evolution. The single most powerful idea in biology, this discovery has withstood decades of criticism to emerge triumphant as one of the most well-checked propositions in human history. Learn about evolution, and you can go to work on diseases, or help find out where species both living and extinct fit into the family tree of life. You can understand the living world, and help preserve human life within it.

Open your mouth about evolution around the wrong people, though, and you can find yourself harassed, ejected from your job and even beaten in the street.

Just ask these people.

Bensteinian Rhapsody

BPSDBVia John Lynch comes MartinC’s “Bensteinian Rhapsody.” (For the tune, try here.) The part right after the guitar solo is my favorite, so here it is, with extra links for added value:

I’ve got a little animation of a cell,
When in haste, copy paste, yes indeed that was the plan, though —
Copyright infringement lawsuit noose is tightening on me —
Sternberg’s ethics, (they’re a shocker)
How ‘bout Crocker, (off her rocker)
And what to say of Guillermo? Guillermo-oh-oh-oh
I’m without tenure, and nobody loves me
He’s just a headcase, embarrassing his faculty —
Spare us the whines of this mediocrity —
Please I pray — on my soul, Will you make it so —
Guillermo! No—, we will not make it so — make it so —
Guillermo! No—, we will not make it so — make it so —
Guillermo! we will not make it so — make it so
Will not make it so — make it so
Will not make it so — make it so
No,no,no,no,no,no,no —
That Eugenie, she’s a meanie, but there’s much worse godless foe!
Beelzebub sent Dick Dawkins and his friend, PeeeeZeeee — PeeeeZeeee, PeeeeZeeeeeeee!

Imaginary Ethics

BPSDBWelly welly welly welly, welly welly well. I don’t normally read the Huffington Post, but thanks to UprightAlice at Pharyngula, I’m hearing that there’s some news worth a listen. This here is James Boyce, who had been upset that Yoko was selling out to the slime of humanity, but then learned more:

I never thought that someone, far less Ben Stein, would take a song as famous as “Imagine” and use it in his film without permission.

However, I have learned that in fact Yoko Ono did not license the song for use in the film Expelled: No Intelligence Allowed, and any use of the song in that film is being made without authorization.

Let’s just. . . savor the moment, shall we?

Ethan Smith at the Wall Street Journal has a piece too. It’s behind a paywall, but going through Google News gets the full story. Smith writes,

Ms. Ono’s lawyer, Jonas Herbsman, of Shukat, Arrow, Hafer, Weber & Herbsman, said in an interview Wednesday: “It was not licensed.” With respect to the filmmakers, he says: “We are exploring all options.” It is not clear what remedies if any may be available to Ms. Ono.

Damn, but this is entertaining. I think the next logical step is for Premise Media to sue Yoko Ono. Right?

Smith also says that the Expelled producers had legally obtained rights to use the Killers’ song “All These Things That I’ve Done.” This goes against the insistence of the Killers’ message board moderators, so somebody has miscommunicated somewhere.

AFTERTHOUGHT: Several commenters here and there are saying that this must all be a ploy to get the Expelled sleaze-fest some publicity. Because there isn’t a real Darwinist conspiracy, they’ll bloody well piss enough people off that they’ll get the smack down and then whine about being repressed. I can’t wait for the next attention-whoring gambit from Premise Media: at this rate, the only way they’ll top themselves is when Ben Stein gets caught with a pound of pure.

Expelled: Immoral, Incompetent

BPSDBAnd so it came to pass that the creationists, realizing that they would be caught ripping off copyrighted material for their propaganda movie, pushed back the release date and did a quick hack job to cover up the stolen footage. Unfortunately, having no actual knowledge of science — if they did, they wouldn’t be creationists — their replacement was rather lacking in the originality department, and the subterfuge did not last.

Just how derivative was the hack job the propagandists threw together? Well, if XVIVO‘s original “Inner Life of a Cell,” beautiful although somewhat inaccurate, were the riff from “Under Pressure,” then the clip seen in the Expelled movie would play the role of “Ice Ice Baby.” Quidam makes the point more succinctly than I could try:

quidamsretort.jpg

At once immoral and incompetent: that’s Expelled for you.

The whining and flailing attempts at damage control have already begun, as Tyler dutifully summarizes. I am hardly surprised to note that the refrain “the Darwinists are trying to censor the truth” has already been sounded. Like clockwork, these people are. Here’s a friendly memo: if you stopped doing flagrantly illegal things, it might be more difficult for the mean, nasty evilutionist bogeymen to bring the strong arm of the Man down upon you. Not that we should expect this FYI to sink in, of course — their media message is now “Help, help, we’re being repressed,” when it’s plain to see that the petty authorities who’ve given their bigotries free rein have been creationists lashing out at science. Do the names Steve Bitterman, Alex Bolyanatz, Richard Colling, Chris Comer, Paul Mirecki, Nancey Murphy, Gwen Pearson and Eric Pianka ring any bells? How about the name of Judge John E. Jones III, who became the target of character assassination and even received death threats for the crime of doing his job? I keep waiting for a biochemist or a geneticist to start issuing death threats like Michael Korn sent to UC Boulder’s biology department, those “terrorists against America.” So far, I wait in vain.

Scientists are men and women with all the foibles inherent in being human. The scientific process seeks to counter some of these flaws through openness and mutual cross-criticism — not always successfully, but often enough to make real progress. Professional creationism, on the other hand, is a disease of the moral organs. It is impossible to defend in an honest way blatant untruths such as the assertions at the heart of creationism; the ignorance and dishonesty inherent in that defense will inevitably infect all aspects of the practice.

(Thanks to the Bad Idea Blog for spotting the image.)

POSTSCRIPT: Above, I described the XVIVO animation as “beautiful although somewhat inaccurate.” The chief illustrator of the film, David Bolinsky, has elaborated on this point:

Wherein I am Short-Tempered

BPSDBOK, it’s time for a joke. This one is appropriate for the whole family and suitable, with minor modifications, for many occasions: What’s the difference between Rush Limbaugh and the Hindenburg?

One is a giant, flaming Nazi gasbag, and the other is a dirigible.

In this case, the gasbag also likes to parade blithering ignorance of science before the whole world. To wit:

In fact, one of these guys in Ben Stein’s movie, guy named Hawkins who’s over at Oxford I think, Oxford or Cambridge, Ben Stein goes over and interviews him in this movie, Expelled. The movie hits April 12th or the 16th. And he said, “Can you explain the origins of life with Darwinism?” “No, we can’t. Well, actually we can, but we don’t.”

Point one: when you’re criticizing a person, it’s good to get their name right, after which you can move on to knowing where they work and, maybe, understanding their position. Who in blazes is this “Hawkins” person? Must be that biologist trapped in a wheelchair. You know, the one who teaches about black holes’ DNA and how the Big Bang came from monkeys — he’s a professor at Oxlonbridgeford. Point two: the sack of lies known as the Expelled movie is opening on the 18th. It’s odd how amidst a fog of untruth, a minor factual error can shine forth like a searchlight.

Rush is all in a lather about some statements by the well-respected physicist Peter Higgs, who way back when proposed what is now known as the “Higgs boson,” a hypothetical particle which would explain “electroweak symmetry breaking” — roughly, why two of the four fundamental forces of the Universe are different from one another. Now, several years back a physicist by the name of Leon Lederman made what many people consider an unfortunate decision: he decided to call a book about the Higgs boson The God Particle. That’s one way to earn back your advance, I suppose, but it also has the perfectly predictable consequence that people will read more into the phrase than was intended.

“B-but I only wanted to draw an analogy between the way that electromagnetism and the weak nuclear force are different and the way that the Tower of Babel legend says people started speaking different languages!”

“Well, you should have called your book The Babel Particle, then. Would’ve sounded cooler, too. I could see Summer Glau playing the lead in a movie called The Babel Particle — she’s a ninja physicist, he’s an archaeologist, they solve crimes — but your title sounds like you had bills to pay and wanted to score some easy Templeton cash.”

I know I shouldn’t blame Lederman for fueling Rush Limbaugh’s insane dribbling, but really, I’m in pain right now, and I might not be acting with my customary kindness and good humor. Just listen:

In other words, he’s looking for a God particle. He’s looking for a particle to prove God. Dr. Higgs, please, just look out the window, Dr. Higgs. You see that tree? You see the grass? Whatever is outside your window, all of it, it’s God particles. Every aspect of it is God particles.

Pantheism has never found a worse spokesman.

Rush goes on to parrot some more of the falsehoods which Mark Mathis and Ben Stein have so kindly packaged, but honestly, they don’t deserve a full fisking. I suspect my time would be better spent channeling my disgust into a screenplay wherein Summer Glau plays a physicist who blends with shadows, walks between the raindrops and beats people up.

Shorter Sal Cordova, Redux

BPSDBAn interesting development has unfolded in the math-blogging world. Sal Cordova, famous for calling Charles Darwin a puppy-killer, has attempted to show that he, Cordova, is not a stupefied ignoramus on the subject of quantum mechanics. Naturally, such ignorance would not be a crime, except that Cordova is hell-bent on using quantum physics to prop up his “Advanced Creation Science.” See here, here, here, here and here if you’ve been suffering a lack of reading material. If, on the other hand, you’re a busy citizen of the high-speed modern world, let us summarize:

If I post a comment in which I fail to address the criticisms leveled at me on a long-dead blog discussion thread and, two days later, crow about it before a sycophantic audience while intentionally mangling my critic’s name, not only will I demonstrate my intellectual superiority over the filthy Darwinists, but also, Jesus will bring me 72 virgins in Heaven.

Oh, by the way, an integral sign is not the same thing as an upper-case S.
