Neil deGrasse Tyson identifies the greatest physicist of all time—in slow motion

March 19, 2014 • 11:05 am

I don’t know why I—or reader Gregory, who sent the link to me—find this video so funny, but I suspect it’s because it makes Tyson sound like he’s been smoking wacky tobacky.  What the astonomer says is right on (he’s describing his hero Newton), but the slowing down—2/3 speed, I think—makes one think that as soon as the video is over, Tyson’s going for the chocolate-chip cookies.

In fact, I find this video quite mesmerizing.

And I’m wondering which other scientists would sound this humorous in slow motion.

Must you be religious to be moral?: A worldwide survey, and its lesson

March 19, 2014 • 8:25 am

A post by C. J. Werleman at Alternet called my attention to a new study by the Pew Research “Global Attitudes Project” that polls people on the perennial (and already answered) question, “Do you need God to be moral”? Pew’s answer, however, is a general “yes,” but that answer is far more common in poorer than richer countries. Here are Pew’s data broken down by country:

PG-belief-in-god-03-13-2014-01

The survey involved 40,080 people.

As you see, the wealthier countries of Europe and Asia have a fairly high proportion of people who don’t think it’s necessary to believe in God to be moral, while sub-Saharan Africa and the Middle East (with the exception of Israel) show a much higher belief that goodness requires godliness. Much of Latin America is also in line with that view.

Note that the U.S. is higher than any surveyed European country in its view that you need God to be moral (53%), while our more sensible Canadian friends are much lower (31%).

Pew also published an interesting plot (divided by country) of the proportion of people who think belief in God is necessary for morality versus the wealth of that country (expressed as per capita GDP). As you see below, the correlation is strong, and undoubtedly highly significant. There are two outliers, though; as Pew notes:

Two countries, however, stand out as clear exceptions to this pattern: the U.S. and China. Americans are much more likely than their economic counterparts to say belief in God is essential to morality, while the Chinese are much less likely to do so.

MMqP0uLBMPUZvKlN1PlYFO1SPQzzmtScb12VPGs_Bu7SmjNpCDyx90OYfzEL1Sqr8-tC0mRYwM8etjwWvYY3LpvKeK3Ngf-l63l1oB-tyxyeMaLufPYM2Ly0zRJKhCazrWORLB8

What is curious here is that the report leaves out any mention of the correlation between religiosity and the belief that goodness requires Godliness.  For it is certain that there is another factor involved in the relationship shown above: belief in God. Those sub-Saharan African countries, and those in the Middle East, are the most religious countries in the world. The U.S. is the most religious of First World countries, and China, because of its Communist past and general lack of goddy religions, is notably nonreligious. Greece and Poland are more religious than Britain or France, and Canada is less religious than the U.S.

In other words, if you plotted religiosity of these nations versus the goodness-requires-God quotient, you’d get the same kind of relationship, but with a positive correlation.  That’s a no-brainer, because clearly countries that are more religious will have inhabitants that see religiosity as more critical to morality.

Curiously, though, that obvious fact isn’t mentioned, and neither is the finding (from other studies) that religiosity is negatively correlated with average income, and especially with indicators of social dysfunction like income inequality, lack of government health care, and so on. I’m willing to bet that if sociological indices of a country’s well being were applied to sub-Saharan Africa and the Middle East, one would find many of those countries to be deeply dysfunctional.

Pew gives one other finding:

There are also significant divides within some countries based on age and education, particularly in Europe and North America. In general, individuals age 50 or older and those without a college education are more likely to link morality to religion. For example, in Greece, 62% of older adults say it is necessary to believe in God to be a moral person, while just 29% of 18- to 29-year-olds agree. In the U.S., a majority of individuals without a college degree (59%) say faith is essential to be an upright person, while fewer than four-in-ten college graduates say the same (37%).

And, of course, older Americans (I don’t know about Europeans) are more religious than younger ones, while more educated individuals in the U.S. are less likely to be religious.

All these data show, then, is that the more religious one is, the more likely one will believe that having faith is necessary for morality. I don’t know why Pew concentrates solely on average income, age, and education, ignoring a factor clearly involved in these relationships—religiosity.

At any rate, the question about whether one needs God to be moral has already been answered in two ways: philosophically by Plato’s Euthyphro argument, and empirically, by observing that countries that are largely godless, like those of northern Europe, are just as moral—if not more so—than places like the U.S. or Middle East. Further, as the West becomes less religious, it has become, as Steve Pinker argues persuasively, more moral.

I’d like to add some data mentioned by Werleman that confirm my suspicion that what breeds religiosity is social dysfunction. Along with some sociologists, I think that those who can’t get help or security from their government, or from a national ethos that citizens should be taken care of, may turn to God for solace and hope. In that sense, Marx was right to indict religion as the “sigh of the oppressed creature.” But I fulminate; let me instead quote Werleman, who cites data supporting the negative relationship between religiosity and social well-being:

Staying with the U.S., this correlation between a high rate of poverty and high degree of religiosity is supported by a 2009 Pew Forum “Importance of Religion” study that determined the degree of religious fervor in all 50 states. The study measured a number of variables including frequency of prayer, absolute belief in God, and so forth. Led by Mississippi, Alabama and Arkansas, nine of the top 10 most religious states were southern. Oklahoma ruined the South’s clean sweep by sneaking in at number seven.

Not coincidentally, led again by Mississippi, Alabama and Arkansas, nine of the top 10 poorest states are also found in the South, while northern and pacific states such as Wisconsin, Washington, California, New York, New Hampshire, and Vermont are among the least religious and the most economically prosperous.

Well spoken! Werleman concludes:

In an earlier piece, I wrote that the primary reason for abject child poverty in these Southern states is that more than a third of children have parents who lack secure employment, decent wages and healthcare. But thanks to religion, these poor saps vote for the party that rejects Medicaid expansion, opposes early education expansion, legislates larger cuts to education, and slashes food stamps to make room for oil and agriculture subsidies on top of tax cuts and loopholes for corporations and the wealthy. Essentially, the Republican Party has convinced tens of millions of Southerners that a vote for a public display of the Ten Commandments is more important to a Christian’s needs than a vote against cuts in education spending, food stamp reductions, the elimination of school lunches and the abolition of healthcare programs.

. . . While the Republican Party retains its monolithic hold on the South, the rest of America remains deprived of universal healthcare, electric cars, sensible gun control laws, carbon emission bans, a progressive tax structure that underpins massive public investment, and collective bargaining laws that would compress the income inequality gap. In other words, without the South’s religiosity, “America” would again look like a developed, secular country, a country where it’s probable for an atheist to be elected into public office, and where the other 50 million law-abiding atheists wouldn’t be looked upon as rapists, thieves and murders.

He’s almost calling for secession!

While I see no necessary connection between atheism and belief in social reform—the kind of reform that makes people more economically and socially secure, and provides government-sponsored healthcare—it’s starting to seem clear that if we want to eliminate religion’s hold on the world, we have to eliminate those conditions that  breed  religion. In that sense, Marx was right (and now wait for the Discovery Institute to start calling me a Marxist!).

This view, which is mine, differs from that of the so-called “social justice warriors,” who see a necessary philosophical connection between atheism and “social justice”.  I don’t agree—atheism is simply a lack of belief in gods, and has no necessary connection with any social view. The connection I see is a tactical and practical one: if, as atheists, we’re interested not only in our own convictions, but in convincing others to believe (or, in this case, disbelieve) likewise, then we must deal with the factors that promote religious belief. If those include social dysfunction, as I think they do, then eliminating faith will require restructuring society.

Lack of government healthcare and income inequality are good places to start.

Seymour Benzer: humor, history, and genetics

March 19, 2014 • 5:53 am

Perhaps you aren’t aware, but Matthew is writing a book on the history of the genetic code—a book aimed at the scientifically-friendly layperson. In his research he sometimes comes across nice anecdotes or little nuggets of humor; and when he sent me this one, I demanded that he post it—with commentary—immediately.  This exchange shows, contra all those “anti-scientism” flacks, that we aren’t a pack of cold, humorless automatons! And there’s some science, too: Benzer was a remarkable, and remarkably smart, character.

Here’s Matthew’s post:

by Matthew Cobb

In 1965, Jacques Monod, François Jacob and André Lwoff were awarded the Nobel Prize in Physiology or Medicine for their work on the control of genes in bacteria and viruses. On hearing the announcement in October of 1965, a friend and colleague of the trio, US geneticist and prankster Seymour Benzer sent this letter to Monod:

In case you can’t read it, it says: “Dr A Lwoff / Dr  J Monod /Dr F Jacob  Mon cher collègue, Please accept my sincere condolences on the occasion of your being forced to share the Nobel Prize with those other two jerks when, in my opinion, you alone fully deserve it. With love, Seymour.”

On 31 December the trio replied in kind:

benz2

I came across these gems on the Institut Pasteur website while I was researching a chapter on Jacob and Monod in my book on the history of the genetic code (out on both sides of the Atlantic in mid-2015, folks!). The trio all carried out their research at the Pasteur lab, and Benzer worked there in the early 1950s, striking up close friendships with the French scientists. This letter is typical of Benzer’s mischievous sense of humour, which was legendary.

Benzer is now most widely known for his pioneering work on the neurogenetics of the fly Drosophila, work that he began in the mid-1960s. Among the things his group discovered were the genetic basis of biological clocks and the first learning mutant, dunce, a fly that couldn’t learn. (In fact, it turned out it could learn, it just forgot really quickly. Dunce was what convinced me to study Drosophila, starting nearly 40 years ago).

However, Benzer began his career in science with a PhD in physics; then, like many young physicists in the post-war world, he switched to biology. He joined the “phage group”, studying the genetics of viruses. From 1954- to the early 1960s Benzer spent his time studying the structure of small genetic region of a virus called the rII region. Using amazingly painstaking techniques, Benzer was able to describe the detailed structure of the region long before genetic sequencing was available, and to show that a gene is not a single unitary structure, but instead contains different regions with different functions. [JAC: before this work, it was widely assumed that genes were indivisible units.]

If you want to know more about Benzer, there’s an excellent book by Jonathan Weiner called Time, Love, Memory (1999), which concentrates on Benzer’s work on flies (and contains an uncredited photo taken by me on the left side of page 210). For a more in-depth look at Benzer’s work on phage, there’s Frederic Lawrence Holmes’ Reconceiving the Gene (2006).

Seymour died in 2007. You can find some nice obits/tributes here and here and there’s a huge oral history interview with him from 1990-91 here.

Readers’ wildlife photos

March 19, 2014 • 4:11 am

Reader Bruce sends photos and information about a local pair of red-shouldered hawks (Buteo lineatus):

For the past few years a pair of red-shouldered hawks has bred somewhere close to my house in Santa Cruz California (I live on campus) but I have not been able to find their nest.  This species has a strange disjunct geographic distribution— a population in eastern North America, a population in California and Baja California, and a vast area in central North America where they are absent. These hawks are gorgeous, as this photo of the male shows; the western population is distinctive and particularly colorful.

IMG_6626adj2

Last summer the pair parked their two fledglings for a few weeks in trees very close to my house. One of the fledglings decided that its favorite perch was a branch a couple of feet from a neighbor’s bird feeder. Fortunately for the local birds visiting the feeder, red-shouldered hawks in our area eat mostly herps [reptiles] and some mammals (pocket gophers). The chick was also a complete klutz as a hunter and we watched it try and fail to catch earthworms on our lawn.

While the chicks lounged, the two parents hunted farther afield for food which they brought back to the chicks periodically. This chick got an alligator lizard and the photo shows the bird just about to polish off the lizards head.

This one got a snake from a parent and this photo shows the tail end of the meal.

Jerry Coyne soon to be neutered and taken to Christchurch

March 18, 2014 • 2:33 pm

Gayle Ferguson, Cat Angel™ for Jerry Coyne and his Four Sisters, sends another picture of Jerry and reports on his growth:

He reached the 1kg mark on the weekend!  All the kittens have been through a growth spurt!  This is him sleeping with his sister Molly.

IMG_2747

Jerry (left, above) will see the last of his testicles either this Friday or next Tuesday, and after a short recovery will be taken to his Forever Home in New Zealand next week:

He flies in the evening of Sat March 29.  He’ll go in the same carrier I use to take them to the vet.  I can only just fit the five of them in there together now!

Gayle promises to send pictures of Jerry Coyne’s Big Trip.

 

Prince Rupert’s Drop

March 18, 2014 • 1:52 pm

Here’s another physics phenomenon that, despite being fascinating, I still can’t quite get my head around. It’s Prince Rupert’s Drop, a phenomenon created when molten glass is dripped in a tadpole-like shape into ice-cold water.  This object and its peculiar physical properties have been known since at least 1625, and are seen in this don’t-miss video by Destin of “Smarter Every Day,” famous for demonstrating how cats right themselves when dropped upside down. But this is not Cat Drop, but Prince Rupert’s Drop. Do watch it: the ultra-slow-motion videos (130,000 frames/sec) are amazing.

After watching this and reading about it, I still don’t understand it completely, so readers who do can weigh in. (Note: you have to explain it better than Wikipedia or Destin!)

Of course, as soon as I saw this, my first impulse was to go online and buy one of these drops, but for obvious reasons they’re not readily available. You can buy them at one place, but they can’t be sent to the U.S. Bummer!
