Does the beauty and effectiveness of math in understanding the world prove anything?

May 1, 2016 • 10:30 am

One of the disadvantages of shopping for food early Sunday morning is that Krista Tippett’s “On Being” program is on National Public Radio at 7 a.m. And, of course, I have to listen, cursing to myself for an entire hour. Why do I do it, you ask? I could say that I need to keep my finger on the pulse of America, and that’s one reason, but it also serves as an Orwellian Sixty Minutes of Hate. (“Hate” is too strong; I think that Tippett and her followers are pitiable, though she’s very well compensated.)

Today’s show, actually, wasn’t so bad (I heard only about 40 minutes), as it featured a man who resisted all attempts to couch his thoughts as woo: Frank Wilczek, an MIT professor who, along with David Gross and H. D. Politzer, won the Nobel Prize in Physics in 2004 for work on the strong interaction.  Tippett being Tippett, the topic, of course, wasn’t really physics per se but, as you can see from the show’s title (“Why is the World So Beautiful?“), the “spiritual.” Wilczek has also written several popular books (I haven’t read them), one with the unfortunate title of A Beautiful Question: Finding Nature’s Deep Design. I doubt that it’s teleological or osculates faith, but I wouldn’t have used the word “design”, which of course implies a Designer.

At any rate, Wilczek tackled an interesting topic: the beauty of mathematics and how well “beautiful and simple equations” describe the structure of the cosmos through physical laws. Why are such simple and “beautiful” theories so useful in describing the laws of physics? The wonder that Wilczek evinced resembled that expressed by Eugene Wigner in his famous 1960 paper, “The unreasonable effectiveness of mathematics in the natural sciences.” Here’s a quote from that paper:

It is difficult to avoid the impression that a miracle confronts us here, quite comparable in its striking nature to the miracle that the human mind can string a thousand arguments together without getting itself into contradictions or to the two miracles of the existence of laws of nature and of the human mind’s capacity to divine them. The observation which comes closest to an explanation for the mathematical concepts’ cropping up in physics which I know is Einstein’s statement that the only physical theories which we are willing to accept are the beautiful ones.

I doubt that most physicists would consider this a “miracle” (Wilczek didn’t come close to using that word); and, as I discuss in Faith versus Fact, there are anthropic reasons for the laws of physics being constant rather than variable (our bodies wouldn’t function, and no organism could evolve, if the laws varied wildly), as well as for mathematics being able to describe the laws of physics.

This leaves two questions: why are the laws of physics described with such simple—and, to physicists, beautiful—equations? And why, as Wilczek maintained, has beauty served physicists so well as a guide to truth? In fact, at one point Wilczek said that, when deriving an equation to explain physical phenomena, “It was so beautiful that I knew it had to be true.”

As a working (or ex-working) scientist, I recoil at such statements. To me, beauty cannot be evidence of truth, though it may be a guide to truth. If so, how does that work? But I even wonder how often mathematical beauty itself, which, after all, doesn’t come out of thin air but builds on previous equations known to describe reality, guides the search for truth completely independent of empiricism.  I’m not qualified to answer that question, nor the questions of whether even more beautiful equations could be wrong, or whether it’s all that surprising that the effectiveness of math in describing physics is “unreasonable.”

Of course Tippett tried to turn all this toward spirituality, and at one point asked Wilczek if this beauty was evidence for Something Bigger Out There that others have called God, but he batted away the question. The woman tries to force everything into her Procrustean Bed of Spirituality. But leaving that aside, I have three questions for readers to ponder, and—especially for readers with expertise in math and physics—to give their take in the comments:

  1. Aren’t there “ugly” theories that describe reality? What is a beautiful theory, anyway?
  2. Are there beautiful theories that physics has proposed that turned out to be wrong?
  3. Is it even worth pondering the question (if the proposition is true) about why physical reality is explained by such simple and “beautiful” equations? My own reaction would be “that’s just the way it is,” but clearly people like Tippett want to go “deeper.”

*********

By the way, at the end of the show, Tippett announced the major donors to the show, and the first of these was—surprise!—the John Templeton Foundation (JTF). I hadn’t heard that before, and the JTF isn’t listed among the “funding partners” on the show’s main page:

WHERE IS TEMPLETON???

But if you search her site you can see the funder of several episodes, and Tippett’s connection with Templeton (she asked the JTF for, and was given, nearly $600,000 to fund nine episodes of “On Being”).

Screen Shot 2016-05-01 at 9.12.59 AM

There would be every reason, of course, for the JTF to sponsor a show that tries to connect science with something “deep”. Further, the blurb for the show on Google, below, jibes very well with Templeton’s aims, for both deal with the Big Questions:

The “Big Questions” are usually those that have no satisfactory answer, like “What does it mean to be human?” or “Why are equations describing the world so beautiful?”, but they serve to reassure the public that science, as Sir John Templeton asserted, could point us to the divine. That was the explicit aim of the millions left by Sir John to the JTF.

Templeton and Tippett—a match made in Heaven!

Daniel Berrigan, antiwar priest of the sixties, dies at 94

May 1, 2016 • 9:06 am

If you didn’t live through the antiwar protests of the Sixties, you may well not have heard of Daniel Berrigan or his brother Philip, activist Catholic priests (the former a Jesuit, the latter a Josephite). But to my generation they were heroes of a sort. Passionately antiwar and devoted to social causes like civil rights and the abolition of nuclear weapons, they were most famous for invading the Catonsville, Maryland Selective Service office on May 17, 1968, absconding with draft files, and then burning them with homemade napalm in the parking lot. That’s shown in the photo below, Philip is on the left and Daniel on the right. Seven other Catholic activists were arrested along with them—the so-called “Catonsville Nine.”

This got all of them three years in prison. After sentencing, Daniel became a fugitive (not a good move for one practicing civil disobedience), but was soon caught and served two years in prison. Over the years, he and Philip were arrested many times for their activities, including trying to damage nuclear warheads. Philip, who secretly married a Catholic nun, died in 2002, but his older brother Daniel, it was announced today, died yesterday at 94 in a Jesuit infirmary in New York. So passes a left-wing icon.

Here’s an image that really brings those times back: Daniel Berrigan, on the right, with his radical attorney William Kunstler after the Catonsville trial. Kunstler was most famous for his defense of the “Chicago Seven“, a radical group indicted for antigovernment activities in 1968.

Daniel was something of a polymath, author of more than fifty books, including works of poetry, and taught at several universities, most notably Fordham. His and Philip’s actions of course angered the Catholic Church, though the brothers said that their political acts derived directly from Catholic teachings.  Archbishop Spellman of New York, a conservative Catholic, exiled him to Latin America, where of course Berrigan became even more radicalized. After he returned, he continued his activism right up to his death.

If the word “social justice warrior” has any positive meaning, it applies to Daniel Berrigan, who did much more than talk about activism, and certainly did not flaunt his moral purity, but took risk after risk in service of his views. I didn’t always agree with him—he flirted with bombing and kidnapping, for instance—but let’s hand it to him: this is the kind of civil disobedience priests would do if they really, truly believed in the ideals of their church.  Are there any Catholic activists like him and Philip still among us? If there are, I don’t know of them.

Readers’ wildlife photos

May 1, 2016 • 7:30 am

Reader Tom Hennessy from Virginia sent some nice flower photos:

I clipped off a bit of a Columbine [Aquilegia sp.] flower from my garden to bring indoors for a few macro photos.  Only after I had the photos up on my computer screen did I realize that I had a tiny stowaway on the stem of the flower.  The first two shots are what I was looking to get from the photos; the next two show the insect which may be some type of aphid, and appears to be sucking on the stem. If I had known it was there I would have tried to get a closer shot of it.

Randy Schenck from Iowa has pelicans (what are they doing in Iowa?):

Another group of American White Pelicans (Pelecanus erythrorhynchos) came by, late afternoon today.  The last picture of this group includes all 14 inthe photo. The first photo shows how a pelican sits with a layered look on the water.  The large wings make up the upper or second layer with the body beneath.  This makes the pelican look top heavy because those huge wings are all folded up on top.  Also note, the bottom of the beak is almost black or muddy and this is probably caused by sticking the long beak down in the water to catch fish.  The bottom of the lake is a very black mud.

Sunday: Hili dialogue (and Leon lagniappe)

May 1, 2016 • 6:15 am

It’s May! It’s May! The lusty Month of May! Yes, it’s May 1: May Day, International Workers Day, and Walpurgis Nacht. But the weather is still dire in Chicago: last night it was chilly and the cold rain, blown by the wind, was coming down sideways. On this day in 1945, Josef Goebbels and his wife Magda killed themselves in the bunker in Berlin, but not before killing their children by forcing cyanide pills into their mouths. On a happier note, in 1956 Jonas Salk’s polio vaccine was made available to the public on this day. And, in 2011, President Obama announced that Osama Bin Laden had been killed by U.S. Special Forces.

On May 1, Joseph Heller was born in 1923, Judy Collins in 1939 (she’s performing this month in NYC), and Rita Coolidge in 1945. Besides the Goebbels family, Spike Jones died on this day in 1965 and Steve Reeves in 2000.  Meanwhile in Dobrzyn, Hili is nosing about forlornly in the kitchen, apparently not having found enough rodents in the orchard:

Hili: There is peace in the kitchen when the table is empty.
A: I’ve already had my breakfast.
Hili: And that’s not fair.
P1040092
In Polish:
Hili: Pokój w kuchni jest kiedy stół jest pusty.
Ja: Ja już jadłem śniadanie.
Hili: I to właśnie jest nieuczciwe.

And in Wroclawek, Leon’s clearly been seeing too many superhero movies:

Leon: Now I’m going to fly!

The best interactive tree of life ever!

April 30, 2016 • 11:45 am

There’s a new, fractally constructed tree of life—with dates of the nodes—called OneZoom, and you must have a look at it. It was created by Dr. Yan Wong (who helped write The Ancestor’s Tale with Richard Dawkins) and Dr. James Rosindell; Luke Harmon contributed to the original idea.  The background and methods are explained on a page you can access by clicking on the magnifying glass at the lower right-hand corner of each searched page, or go here. It’s still a work in progress, and you can help the tree grow by sponsoring a leaf. The project is a charity, so your donations are tax free.

This just went up yesterday, and it’s already so extensive that, I’m told, if you printed the whole thing out it would be seven times larger than the solar system! I can’t vouch for that, but the fractal design is certainly impressive. Click on the screenshot below to get started, and remember these instructions:

Each leaf represents a different species and the branches show how they are related through evolution.

This tree of life is explored like you would a map, just zoom in to your area of interest to reveal further details.

To zoom you can use a touch screen (if you have one) or scroll up (zoom in) and down (zoom out) on your mouse or trackpad.

The search icon (second from the left) gives you an easy way to search or go straight to popular areas of the tree.

The location icon (third from the left) shows you which part of the tree of life you are looking at in the context of all life on earth.

If a leaf is coloured red this means the species it represents is known to be threatened with extinction.

Leaves with a dotted outline represent parts of the tree that are not filled out yet, if you sponsor one of the species in this part of the tree we will expand the tree to include your species.

Here’s one example you can use. Click to stop the zoom, and use your mouse or touchpad to get to clickable icons.

For example, go to the mallard (here) to see the full capabilities of the system.

Finally, there’s a special version to accompany The Ancestor’s Tale, with all the common ancestors between Homo sapiens and other species numbered.

Student demonstrators disrupt talk, demonstrate immaturity

April 30, 2016 • 10:30 am

Milo Yiannopoulos, an editor of the right-wing website Breitbart, is a professional provocateur. He’s a gay man who goes around criticizing not only the student “offense culture,” which is a good thing to do, but also feminism, which is a bad thing to do. He doesn’t distinguish between different brands of feminism, but simply dismisses the whole enterprise as “a cancer,” as he did in a recent speech at the University of Massachusetts at Amherst. I disagree with that, and wouldn’t go to see him were he speaking on my campus. But if I did, I’d sit and listen quietly, and then discuss his views either on this site or during the Q&A period.

But Yiannopoulos is also savvy, and has embarked on a tour of American colleges. As his views are a flashpoint—a “trigger”—for authoritarian Leftist (AL) college students, their reaction is predictable. The conservative and sexist elements in his audience applaud him, but they’re drowned out by the noises, hoots, whistles, and demonstrations of the AL students, who repeatedly shout out to interrupt Yiannopoulos and create demonstrations that, in the end, do nothing but reinforce the stereotype of ALs as spoiled brats, increasing the opprobrium of people who might otherwise hear them out.

Here’s an video of Yiannopoulos speaking about “safe spaces” at Rutgers in New Jersey, whereupon a group of ALs shout, whistle, and finally smear themselves with fake blood while having a mass conniption. Who wouldn’t be turned off by such demonstration?

The whole canny psychology of this tour is described by New York Magazine. Its commentary is pretty accurate—save for one thing (I’ve put it in bold):

Here’s how it works: Yiannopoulos goes to a college. He says dumb and offensive trolly things. Students react with outrage and sadness, either during the talk itself or in gatherings afterward. Inevitably, some of them either freak out or burst into tears, because college students are college students. Breitbart and other right-wing outlets then trawl for student-paper coverage, footage of angry students, or both, and then cover these reactions as “proof” that everything Yiannopoulos says about colleges and modern society — something something free-speech SJWs feminazis lesbians — is true.

Here’s the part that’s troublesome: “because college students are college students.” That’s not necessarily true: college students are usually over 18, which means they’re adults. By that time they should have learned to sit quietly and listen to a speaker, and not suppress the speaker’s words through interruptions, demonstrations, and the like. They should have learned some civility. They should have learned that the best way to combat the ideas of such a speaker is by questioning them at question time, writing posts on their website or Facebook, and even demonstrating outside the venue. That is what we did when I was in college—a time of great ferment about civil rights, the Vietnam War, and so on. It’s simply a fact that the civil disobedience and nonviolent protests of the civil rights movement carried over to general student unrest, and most of us would have found it unthinkable to make such a ruckus during an opponent’s speech.

Let me tell you a story. At my graduation in 1971 from William & Mary, most students wanted a left-wing graduation speaker. Instead, the administration, almost to slap us down, chose Thomas Downing, a conservative and undistinguished member of the Virginia Legislature. (The administration was quite conservative then.) Did we go to graduation and shout during his speech? We didn’t even consider that. Those of us who were leftists wore black armbands over our graduation gowns, and some put peace symbols on their mortarboards. As valedictorian, I was called out from the stage to stand up and be recognized. I did, but made the “black power” fist when I stood up. (I’m not necessarily proud of that now, but that’s all I could do, and I got a lot of flack from the College for it.)

I say this not to demonstrate our left-wing credibility, but the fact that, at least among those leftist students I knew, the idea of disrupting such an event was unthinkable. Yes, it did happen sometimes, but it was a rarity. Instead of disrupting, we made a quiet protest, and later had a “counter-commencement” with our chosen speaker being Charles Evers, brother of murdered civil right leader Medgar Evers.

The lesson is this: if you want any respect for your ideas, you can’t act like spoiled brats. Protest in a civil, dignified, but passionate way, and if you must disobey the law, do so like the civil rights protestors did: civilly and without resistance. (This only works in a democracy, of course: civil disobedience of the Jews against the Nazis would have failed miserably.)

Students like the entitled whingers above only discredit their own leftist ideas—and some of those ideas are not only worth hearing, but worth adopting. When New York Magazine says “college students are college students”, it must be referring to the arrogant and self-absorbed Snowflake Students of the past five years. It is, in effect, trying to excuse the students’ behavior on the grounds of their youth.

But it’s not inevitable that students must behave in such a stupid way. I hope they realize that if they really want to spread their ideas, this is not the way to do it. You don’t win a debate like this by refusing to let the other side speak. When you do that, as AL students have been doing repeatedly—and not just in response to Yiannopoulos—they lose in the court of public opinion.

These students, deeply marinated in identity politics and virtue signaling, are playing right into Milo’s hands. They aren’t really trying to change minds, but trying to censor others while demonstrating their own moral purity. Their actions have an effect directly opposite to what they say then want: they let the conservatives, the sexists, and the Trump-ites win.

Caturday felid trifecta: Program places cats in jobs, favourite British cats, atheist cat ignores Muslim prayer

April 30, 2016 • 9:30 am

FYI: This is post #13,000 on this site.

The Minneapolis Star Tribune describes a program whereby cats scheduled to be euthanized by the Humane Society (remember, they’re not a no-kill organization) tries to find “working cat” jobs for more difficult moggies: feral cats, skittish cats, and so on.

These cats aren’t the instant cuddle buddies most desire. Some recoil at human touch. Some don’t use litter boxes regularly. Some are hissy and cranky. But they’re otherwise healthy and could be a good match for hobby farms, warehouses and other homes and businesses interested in nontoxic, trap-free rodent control.

Plus, many even become sociable in stable settings, lending themselves to the “work” of business mascot and customer magnet, said Anne Lally-Rose, site manager at the Humane Society in Buffalo.

“I’d love to see them in bookstores, in fire stations, police stations, any kind of business,” said Lally-Rose, who helped spearhead the project. “There’s something kind of nifty about having an office cat around.”

. . . Nearly 70 little laborers have been adopted since the working cats began as a pilot project last year, said Lally-Rose. Half were adopted since January, when it was launched in earnest. Just three have been returned.

I believe that every bookstore should have a cat!

Google Doodles honor Claude Shannon and Hertha Marks Ayrton

April 30, 2016 • 8:30 am

claude-shannons-100th-birthday-5731852344098816.3-hp

Today’s Google Doodle celebrates the birthday of Claude Shannon in 1916 (died 2001), called the “father of information theory,” but also the father of digital circuitry, which uses binary zeroes and ones (he’s juggling them above) to design electrical switching circuits. (As the New Yorker notes in a profile, “Claude Shannon, the father of the Information Age, turns 1100100.”) If you click on the Doodle, you’ll go to a list of links about Shannon. As the New Yorker article notes:

First and foremost, he introduced the notion that information could be quantified at all. In “A Mathematical Theory of Communication,” his legendary paper from 1948, Shannon proposed that data should be measured in bits—discrete values of zero or one. (He gave credit for the word’s invention to his colleague John Tukey, at what was then Bell Telephone Laboratories, who coined it as a contraction of the phrase “binary digit.”)

I hadn’t noticed, but a reader let me know, that yesterday Google also had a Doodle marking the birthday of engineer, mathematician, and physicist Hertha Marks Ayrton (1854-1923):

hertha-marks-ayrtons-162nd-birthday-6049205031272448-hp2x

Time Magazine describes her achievements, which includes breaking (or at least butting up against) a scientific ceiling:

Hertha Marks Ayrton became the first woman to present her own work to the U.K.’s Royal Society when she stood in front of the scientific academy in 1904 and read “The Origin and Growth of Ripple Marks.” Until then, scientists were baffled by the creation of ridges in sand when a wave washes over a beach.

To celebrate Ayrton’s scientific discoveries and victories over discrimination, Google has honored the British engineer, mathematician, physicist and inventor with a Doodle, on the 162nd anniversary of her birth. In addition to unlocking the mystery of ripples, Ayrton also became and expert on electric arcs, widely used in lighting at the time.

In 1906, the Royal Society awarded Ayrton with its prestigious Hughes Medal for her contributions to physical sciences. But the academy denied her the honor of becoming a fellow, because she was married. Addressing this kind of gender discrimination in science, Ayrton wrote: “An error that ascribes to a man what was actually the work of a woman has more lives than a cat.”
