The quote in L.A. is gone!

December 16, 2013 • 11:22 am

I was supposed to be interviewed today by a science reporter from KPCC, the public radio station in Los Angeles; the topic was to be the infamous “God quote” at the Natural History Museum of Los Angeles County, something I posted about here and here. Here’s the quote to which I objected (but which some readers found inoffensive):

natural-history-museum

The quote is gone now.  I got this email from an anonymous source (posted with permission):

The anonymous donor quote at the NHM has been removed. My second-hand source tells me it will not be replaced. No doubt your efforts, coupled with those of a science reporter at KPCC looking into the mess, compelled the administration to finally do the right thing. Without doubt, you and your WEIT audience were the driving forces, for which I’m grateful.

I don’t know what happened, but I think those of us who objected played some role in this, as I know some readers wrote to Museum officials. I also suspect that some of the curators objected, and I’m pretty sure that the inquiring KPCC reporter is the same guy who was going to interview me, and his inquiries were the final blow.

If I get any other information I’ll convey it, but for now I’m pleased that God is out of the Museum and no longer gets credit for “creatures.”  It’s a victory for secularism, for sure.

Since creationist Michael Egnor posted a snarky piece at Evolution News and Views yesterday, gloating about the sign and accusing me of failed attempts to get religion out of a public museum, expect the whining from the Discovery Institute to commence in 3. . . 2. . . 1. .

A new Polish rationalist website, now with more cat

December 16, 2013 • 11:08 am

My dear friends Andrzej Koraszewski and Malgorzata Koraszewska, who previously did all the work on the Polish website Racjonalista (and who are owned by Hili, the the most famous cat in Poland), have left that site to start their own: “Listy z naszego sadu” (“Letters from our orchard”). It’s attractively laid out and will contain all the science pieces and articles on religion, rationalism, and atheism that were present at the old site.  As a bonus, it will feature a much expanded presence of Hili, who was virtually absent on the old site.

Here’s a screenshot of part of the inaugural page, which went up today.  Besides the diverse panoply of pieces, you’ll see seven—count them, seven—pictures of cats, including the lovely shot of Hili that adorns the masthead. Note as well the links to the Hili Dialogues.

Most readers here don’t understand Polish, but if you do, you’ll want to keep up with that site. Or, if you’re a reader in Poland, bookmark it. I’ll be over there in twelve days to work on my book and chill out a bit, so expect to see Professor Ceiling Cat in some Hili Dialogues.

And best of luck to Andrzej and Malgorzata in their new venture! With rationalism and cats (a natural pairing, like peanut butter and jelly), how can they lose?

My interview at TAM

December 16, 2013 • 10:08 am

When I spoke at TAM last July, I was interviewed (along with many other speakers) by the Richard Dawkins Foundation for Reason and Science. Reader Lesley called my attention to the fact that they have just posted the video (part 1). For better or worse, here it is, but remember that at the time I was pretty sick with a stomach bug (I can’t bear to watch this now). I’m not sure whether there will be a part 2; we certainly taped more than this.

The interviewer, who did a good job, was Joel Guttormson, Outreach and Event Coordinator for the RDFRE.

This bit is on the evidence for evolution, though my talk at TAM was about the incompatibility of science and religion.

An unusual antipredator defense

December 16, 2013 • 8:38 am

Yesterday, reader Roo sent me the Torygraph‘s photo of the day, which is an assassin bug. The caption is below (I’m not sure why they use the past tense):

These ruthless Assassin bugs hid from potential predators using a camouflage cloak – made from the bodies of ants they had killed. The deadly insects paralysed the ants by injecting them with a toxic enzyme before sucking them dry. They then piled the dried-out corpses on their sticky backs to act as a defence against other predators, such as jumping spiders. Picture: Guek Hock Ping/Photoshot/Solent News

Picture 1

Note that assassin bugs (unlike “ladybugs,” which are beetles in the order Coleoptera) really are bugs : they’re in the order Hemiptera, or “true bugs.” (If I want readers to learn anything from this site, it’s to use the word “bug” properly!) They’re also in the order Reduviidae, some of whose New World species—probably not the one above—carry the protozoans that cause Chagas disease, an often asymptomatic but sometimes fatal illness. For many years people thought that Darwin had been infected with Chagas on his Beagle voyage, accounting for his frequent and lifelong bouts of illness, including malaise and vomiting. We’ll never know for sure, for doctors have suggested many other causes, ranging from simple nervousness to the latest Darwin-illness fad, cyclical vomiting syndrome.

Assassin bugs are so called because they stick their snout (“rostrum,” if you want to be technical) into the prey, injecting a saliva that liquifies the prey’s insides. They then suck it dry.

It’s interesting to speculate how this evolved. This adaptation (and who can deny that it is one?) involves both a morphological trait (a sticky back) and a behavioral trait (the tendency to put the husks of your prey onto your back). Without that sticky back, you have no initial advantage, so I suspect that the evolution of this mimicry began simply because the bug had a back that could adhere to dead insects, perhaps because of cuticular lipids that served other functions, like desiccation resistance or attracting mates. Perhaps a prey accidentally adhered to one of the bugs with a particularly sticky back, and that individual gained an advantage, as it was simply harder to attack and eat. This would give an advantage to genes producing not only stickier backs, but also  promoting any tendency to place sucked-out prey on your back.  I am curious whether the ant carcasses are inherently sticky too—as they appear to adhere to each other—or whether the bug actually puts something on them to help them stick together.

But this is all speculation. What is on firmer ground is the idea (still probably not demonstrated through experiment) that this is a remarkable adaptation to deter predation. I wouldn’t call it “mimicry” (unless predators avoid piles of dead ants), for this ant-covered bug isn’t really deceiving the predator by “pretending” to be something else. It’s simply making it harder for predators to grasp and eat them.

In defense of Hitchens

December 16, 2013 • 6:47 am

Christopher Hitchens died two years ago yesterday—has it been so long?—and yet journalists continue to attack him. To me that’s a measure of his influence, and I see the attacks as motivated by two factors: resentment of the success of New Atheism, and the laziness of journalists, who can, by attacking strident and militant atheists (even if they’re dead) draw traffic.

One of the prime attack dogs in the War on Atheism has been Salon, which has published a number of pieces attacking Hitchens, Sam Harris, Richard Dawkins, and other prominent atheists. About a week ago I discussed Salon‘s latest attack on Hitchens, “What Hitchens got wrong: Abolishing religion won’t fix anything,” by Sean McElwee.

Well, I was amazed to see that, in Saturday’s Salon, Atlantic editor Jeffrey Tayler also wrote a withering broadside against McElwee’s piece and a defense of Hitchens: “The real new atheism: rejecting religion for a just world.” I was pleased to see that we went after many of McElwee’s same points, but Tayler does a much better job I.

He first dismantles McElwee’s stupid claim that Hitchens thought religion was responsible for all humanity’s ills (McElwee discredited himself at the outset with that bit of logic), and notes that, contra McElwee, Hitchens did not advocate the second Iraq war because he thought it would be the final overthrow of religion. (Tayler, by the way, thinks that Hitchens was mistaken.)

No, this was not how Hitchens viewed the second Iraq war. He advocated invading Iraq to overthrow Saddam, who was, he contended, guilty of crimes against humanity, and he (mistakenly) assumed a stable democracy would result from the dictator’s ouster.

Hitchens understood the secular nature of Saddam’s Ba’ath Party, which made all the more puzzling and problematic his stubborn insistence that Saddam was colluding with Al Qaeda. But McElwee then asserts that “the force of rationality and civilization was led by a cabal of religious extremists” – in the Bush administration — which “was of no concern for Hitchens.” George W. Bush was a convert to Evangelical Christianity, which does not necessarily make him a “religious extremist,” and the (mixed) faiths of the Iraq War’s other architects (Dick Cheney, Condoleeza Rice, Paul Wolfowitz, Douglas Feith, et al.) did not fuel their zeal for deposing Saddam.

McElwee proceeds to mischaracterize Hitchens’ post-9/11 worldview as a “war between the good Christian West and the evil Muslim Middle East.” How McElwee can expect us to believe this of Hitchens, who authored a book (“The Missionary Position”) denouncing Mother Theresa as a fraud and relentlessly attacked Christianity, baffles me, as does McElwee’s blindness to his own blunder. Is Hitchens now, according to him, pro-Christian?

Tayler then rebuts McElwee’s equally dubious claim that Muslim jihad has nothing to do with the tenets of Islam, but is political: a reaction to colonialism:

Stripping jihad of its religious grounds invites nothing but confusion. Jihad in Arabic means “struggle,” but, with respect to Islam, denotes “a struggle in the name of faith,” which includes holy war against infidels waged as a matter of religious duty.  Such jihad is, ipso facto, religious.

And it’s really refreshing to read a critique of those who soft-pedal religion:

McElwee then tendentiously defines religion so as to paper over its often decisive role in precipitating conflicts. Though he allows that it might “motivate acts of social justice and injustice,” “[r]eligion is both a personal search for truth as well as a communal attempt to discern where we fit in the order of things.” Religion first and foremost consists of unsubstantiated, dogmatically advanced explanations for the cosmos and our place in it, with resulting universally applicable rules of conduct. A good many of these rules – especially those regarding women’s behavior and their (subservient) status vis-à-vis men, and prescriptions for less-than-merciful treatment of gays – are repugnant, retrograde, and arbitrary, based on “sacred texts” espousing “revealed truths” dating back to what the British atheist philosopher Bertrand Russell justly called the “savage ages.” (Islam by no means has a monopoly on such rules – check Leviticus for its catalogue of “crimes”: working on the Sabbath, cursing one’s parents, being the victim of rape – that merit the death penalty.) Just how such “holy” compendia of ahistorical, often macabre fables are supposed to help anyone in a “personal search for truth” mystifies me.

Without their truth claims, most religions lose force as a social institution, and I don’t understand why believers (McElwee is a Christian) refuse to see that. If McElwee absolutely knew that Jesus was not divine and was not resurrected, would he still be a Christian? Without that, you not only lose motivation to adhere to the faith, but your “acts of social justice” will no longer be based on your perceived interpretation of God’s will and the words of Jesus. Or, if you don’t believe the tenets of your faith, and do good from secular motivations, you can’t really call yourself a Christian. It’s like calling yourself a Republican when you embrace the Democratic platform and always vote for Democrats. This is why it’s crucial to ask Christians, for instance, if they really believe in the Resurrection, Heaven, Hell, the virgin birth, the divinity of Christ, and the fact that the Bible is anything more than a man-made text.  If they don’t, they’re just secular humanists using fancy language. And that is why liberal Christians always waffle when asked those questions. In their hearts they do believe, for they have a sneaking suspicion that there’s an afterlife, but are embarrassed to admit publicly that they believe in such foolish superstitions.

But I digress.  Tayler attacks McElwee’s claim that atheists should lay off religion because it’s best criticized from the inside, that we need a Gouldian truce between science and religion, and so on.  I’ll leave you to read the piece for yourself, and you should, for Tayler’s language is strong and uncompromising, much like that of Hitchens’s himself.

And there’s a nice ending:

The sooner we accord priests, rabbis and imams the same respect we owe fabulists and self-help gurus, the faster we will progress toward a more just, more humane future. Enlightenment must be our goal, and that was what Hitchens advocated above all.

On second thought, I think Tayler went a bit too far here. In truth, many self-help gurus—like Deepak Chopra and Andrew Weil—are accorded enormous respect in our society, often far more respect than clerics. What Tayler should have said is that we need to accord priests, rabbis, and imams the same respect we owe believers in UFOs, Bigfoot, Nessie, and Scientology.

Tayler really hasn’t crossed my radar screen, but I like the way he writes and his refusal to coddle the faithful.

We’re #2!

December 16, 2013 • 5:52 am

Traffic on this site is unpredictable. On an average day it’s around 20,000 views (a bit lower on the weekends), but sometimes things spike for reasons that are completely unpredictable.  Last Tuesday I posted a gif of a bacterium sitting on a diatom sitting on an amphipod, which was a pretty cool bit of faux-zooming photographed by James Tyrwhitt-Drake on a scanning electron microscope. And I forgot that I had posted the very same animation a while back. It’s a really nice piece, but it’s not Anna Karenina, elevator drama, or even my own writing.

Nevertheless, views began spiking, hit 153,000 by the end of the day (the record is 304,000, on the day of the Mother Teresa post, last July 8) and are already nearly 31,000 today already—and it’s not even 7 a.m.

What happens, of course, is that some other place, usually reddit, picks up a post, sending elebenty gazillion people over here. This time, however, it appears to be Facebook, which accounted for 106,000 views yesterday, and since I don’t have many “friends” on that site, it must have been re-Facebooked. I don’t know; I’m a n00b at social media and don’t track this stuff down. BUT, I checked the ranking of WordPress websites and, to my amazement, this place is almost on top for the period (I don’t know how WordPress calculates these ranking), second only to a Blog of Disrepute, but beating two Simpsons sites:
Picture 1

So, here is my prayer to Ceiling Cat, “O holy Feline Father, please let me be #1, just for one brief shining moment, and if you can do that, I will be a good boy FOREVER. Just let me beat “Watts Up With That?” one time, and I will spread Your Good News for the rest of my life.”

I think it’s too late, though.  There is no chance of beating that perennially popular climate-change-denialist site.  And, as I once saw in a poster stuck on the lab wall of a particularly ambitious professor, depicting a golf ball stopped at the lip of the hole, “It is a sad fact that, regardless of effort or talent, second place only means that you are first in a long line of losers.”

Who knows what will capture the attention of folks on the Internet? Who would have predicted, for instance, that a tubby Japanese cat would become a world celebrity.  Oh hell, I might as well show Maru with his new tabby companion, Hana:

A Martian cavern – or is it?

December 16, 2013 • 1:05 am

by Matthew Cobb

We’ve featured the amazing images from the HiRISE Mars orbiter before. Here’s a stunning crater that was captured in 2011, on the slopes of Pavonis Mons, one of the massive extinct volcanoes on the Red Planet.:

crater

Shane Byrne at the HiRise site run jointly by the University of Arizona says that the hole at the bottom is 35 m across, and about 20 m below bottom of the crater (they worked this out by the movement of the shadows) (All photos NASA/JPL/University of Arizona). The cavern that we are looking into is of unknown size. Shane writes:

Caves often form in volcanic regions like this when lava flows solidify on top, but keep flowing underneath their solid crust. These, now underground, rivers of lava can then drain away leaving the tube they flowed through empty. (…) The origin of the larger hole that this pit is within is still obscure. You can see areas where material on the walls has slid into the pit. How much of the missing material has disappeared via the pit into the underground cavern?

Here’s a larger version (click to see the stunning full size image). Imagine you are an explorer on Mars – could you walk down the slope of the crater, and then use a rope to get down into the bottom of the cavern, and look back up? Or is the surface of the crater thin and would it break under your weight?

Here’s the original image that caught the attention of the HiRISE team:

Caves and Craters

Of course, it might not be a crater and a cavern at all. Here are two other options:

EDIT: Another option is that it is the Martian version of the Great Pit of Carkoon from Star Wars:
