Former Canadian Senator Pat Carney Has Trouble Getting Along with Atheists

Last Sunday (March 3, 2013) CBC radio aired a discussion on "Does religion have a place in public life?" The host was Rex Murphy. You can listen to the entire thing at: Does religion have a place in public life?.

I want to draw your attention to a segment where former Canadian Senator Pat Carny talks about her esperience with atheists. (Carney was a cabinet minister under Prime Minister Brian Mulroney.) The excerpt is embedded below. If it doesn't work, click on Pat Carney MP3.

Here how she begins ...
... you're debating the wrong question. It's not the role of religion in public institutions. it's the difficulty of being a person of faith working with people who haven't any ... any religion. And I'm speaking as someone with 27 years in parliament ...
It gets worse. She claims that atheists simply don't share her values, such as the Golden Rule, therefore you can't find common ground when trying to make policy.

All I can say is that it's a damn good thing she doesn't live in Western Europe because those secular societies clearly don't exhibit any of the values she holds so dear.

Saturday, February 28, 1953

Friday night, after cutting out the cardboard bases, still deep in defeat Watson went home and then to the theatre. Saturday morning, February 28, he came in, cleared a place to work, got out his cardboard cutouts.
Though I initially went back to my like-with-like prejudices, I saw all too all too well that they led nowhere. When Jerry [Donohue] came in I looked up, saw that it was not Francis, and begin shifting the bases in and out of various other pairing possibilities. Suddenly I became aware that an adenine-thymine pair held together by two hydrogen bonds was identical in shape to a guanine-cytosine pair held together by at least two hydrogen bonds. All the hydrogen bonds seem to form naturally; no fudging was required to make the two types of base pair identical in shape.1
Watson stumbled into this part of the solution visually, from a shape, a representation, and that had happened several times before; that is the way his mind works. Note two of the four kinds of bases have the same contour. Watson found that the purine adenine, a fused double ring with other atoms fringing it at several points, could form two hydrogen bonds with the pyrimidine thymine, a single ring, when he placed the two cutouts side by side in the right way. The bond were the correct length, and were straight lines, N—H--O or N--H—N, as Pauling's model-building precepts required. Guanine and cytosine made hydrogen bonds the same way. The pairing could not be switched, however, for then the various atoms around the fringes got in each other's way. But when an A-T pair was laid on top of a G-C pair, the two compound shapes were exactly congruent. Such pairs could fit inside the backbones without bulges or pinches.

Donahue said these pairs agreed with what he knew. Crick, when he came in, immediately pointed out that the way the bases in these pairs would attach to their sugars meant that the two backbones ran in opposite directions, just as they had to do. Each chain could include both purines and pyrimidines, with pairs flipped over. That satisfied the dyadic symmetry. Chargaff's ratios were satisfied, too. The bases could appear in any order on one chain. Once that order was fixed, though, the base pairing, guanine always with cytosine and adenine with thymine, determined a complementary order on the opposite chain.

That morning, Watson and Crick knew, although still in mind only, the entire structure: it had emerged from the shadow of billions of years, absolute and simple, and was seen and understood for the first time. Twenty angstrom units in diameter, seventy-none billionths of an inch. Two chains twinning coaxially, clockwise, one up the other down, a complete turn the screw in 34 angstroms. The bases flat in their pairs in the middle, 3.4 angstroms and a tenth of a revolution separating a pair from the one above or below. The chains held by the pairing closer to each other around the circumference one way than the other, by an eighth of a turn, one groove up the outside narrow, the other wide. A melody for the eye of the intellect, not a note wasted. In itself, physically, structure carried the means of replication—positive to negative, complementary. As the strands unwound, at double template was there in the base pairing, so that only complementary nucleotides could form bonds and drop into place as the daughter strands grew. ... one doubts, of course, that Crick and Watson altogether realized, that morning, what they had seen. "We have discovered the secret of life," Crick told everyone within earshot over drinks that noon at the Eagle. It was not the entire secret of life, yet truly for the first time at the ultimate biological level structure had become one with function, the antimony dialectically resolved. The structure of DNA is flawlessly beautiful.

Living on Lava

The Big Island (Hawaii) is one giant pile of lava from five different volcanoes. The large one, slightly below center in the photo, is Mauna Loa and it is still an active volcano. You can see streaks of old lava flows spreading out from the summit. Mauna Kea, the slightly higher volcano above center, is now dormant.1 The active volcano that tourist visit is Kilauea, below and to the right on Mauna Lao.

We are staying at the Hilton resort in Waikaloa. It is built on the lava flow from 1859 where it spilled into Kiholo bay [The 1859 eruption of Mauna Loa and its human impact].

This is the dry side of the island and the surrounding area is very desert-like. As you can see from the photo I took (below), the resort area is not desert at all. That lush vegetation requires constant watering. (I don't know were the water comes from.) You can also see the parts of the lava flow that have not been transformed. It's very impressive to see it up close.

The photos are from the balcony of our apartment. When we woke up today there was snow on the top of the mountain. The temperature here is about 30°C (or 86°F for the only major country that isn't metric.2)







[Hat Tip: Ms. Sandwalk took the photos of snow-capped Mauna Loa with her telephoto lens.
1. That's where the Hawaiian observatories are located.
2. Liberia and Burma are the other two countries that aren't metric.

Wakiki Beach

This is a view of Wakiki Beach in Honolulu, Hawaii. I took it from LuLu's Surf Club where I was eating fish tacos and drinking Hawaiian beer. (The fish tacos were horrible. The beer was acceptable.)

I took a few more photos of the beach while we were strolling along the path behind the beach. It was a beautiful day with temperatures hovering around 28°. We stayed in a hotel a few blocks away 'cause we couldn't afford the big hotels that were right on the beach.




USS Arizona

The USS Arizona (BB-39) is an American battleship built during World War I. It was modernized and upgraded in 1930.

The Arizona was hit by a Japanese bomb during the attack on Pearl Harbor on Dec. 7, 1941. The magazine in her forward turret exploded and the ship sank within minutes. The explosion killed 1,177 of her crew. The ship was not salvageable, unlike most of the other ships sunk on that day. The USS Arizona Memorial was built over the remains of the ship to honor the men who died in the attack. Here's an aerial view of the memorial.

We visited the USS Arizona Memorial on Thursday Feb. 14, 2013 and I've included some of my photos. Click to enlarge, especially the last two photos.

USS Missouri

The USS Missouri is an American battleship commissioned in June 1944, toward the end of World War II. It served as the flagship of the American Third Fleet under Admiral William F. Halsey, Jr. In early August 1945, the Missouri was bombarding installations on the coast of Japan when the atomic bombs were dropped.

On September 2, 1945 the Missouri was docked in Tokyo harbor. Japanese representatives signed the surrender documents that formally ended World War II. The brass disk (below) is the site where the signing took place.

On Thursday (Feb. 14, 2013) we visited the Battleship Missouri Memorial in Pearl Harbor, Hawaii.

Hawaiian Cuisine

I think it's important to sample the local customs whenever you travel. In this case, I'm on a mission to experience genuine Hawaiian cuisine.

We began on the first full day of our visit with a delicious spam & egg bun at a small cafe in Honolulu near the beach at Waikiki. The spam had just the right flavor (I thing it was genuine Hormel spam, probably made in the USA.) I actually prefer Prem but it's much hared to find.

Guess Where I'm Going?

We're leaving tomorrow to visit a place I've never been. I'm really looking forward to it, especially the "red bits" in the image.

I may be too "busy" to post much in the next two weeks.

PZ Myers Can't Write About Evolutionary Psychology

PZ Myers wants to write a serious post about evolutionary psychology but he can't.

Why not? Here's what he said on Kate Clancy tackles Evolutionary Psychology.
I’ve still got plans to post more on this subject, but an unfortunate event has blocked me. I was going to make my next post on evolutionary psychology one that focused on some of the papers, and in particular, I wanted to discuss a good paper or two, so that I could start off on the right tone. And people sent me links and papers.

Only problem: they were all awful. Every one. I couldn’t believe that even these papers that some people were telling me were the best of the bunch were so lacking in rigor and so rife with unjustified assumptions. I read through about a dozen before I gave up in disgust and decided that there were better things to do in my time.

I’d ask again, but I was burned so badly on that last go-round that I’d have a jaundiced view of any recommendation now.
I understand his pain. I've often asked for good examples of evolutionary psychology and gotten nothing but garbage. For example, an evolutionary psychologist named Gad Saad once sent me a list of The Great, Profound, and Valuable Works of Evolutionary Psychology. At some point we have to question the value of an entire field if it can't come up with even a handful of high quality papers.

Craig Venter Discusses the Tree of Life

I don't know where this clip comes from or when it was made but it's being promoted on YouTube as "Dr. Craig Venter Denies Common Descent in front of Richard Dawkins!" The link was posted by someone in a comment to a previous post on Sandwalk.

Everything that Ventor says is correct. He didn't need to quibble about the universality of the genetic code but it's true that there are variants.

His point about the tree of life is correct, especially in a discussion about the origin of life. It's unfortunate that Richard Dawkins repeatedly makes such an issue about the tree of life because he's on shakey ground when he does that. I assume that Dawkins hasn't studied the problem. However, he's in good company since most scientists don't understand the problems with the early tree of life. The early history of life looks more like a bush with many interconnecting branches due to horizontal gene transfer [The Tree of Life].

Here's a video of the complete debate. The relevant part, according to the creationists, begins at 9 mins.

Darwin's Dead Idea and the Man Who Helped Kill It

A new book has just been published. The title is "Darwin's Dead Idea and the Man Who Helped Kill It." Here's the description on Amazon.
"Darwin’s Dead Idea and the Man Who Helped Kill It" makes for highly engaging reading. Witness the fascinating journey of a smart, inquisitive adolescent rejecting his school’s ask-no-questions religious indoctrination into a mathematician, philosopher, and scientist of the highest order, one who today is powerfully and persuasively challenging academia’s reigning answer to the questions that haunt us all: Where did we come from? Why is there something rather than nothing? A leading spokesman for the scientific theory that is shattering materialist assumptions about reality and the origin of life, Dr. William Dembski responds to probing questions from James Barham, general editor of TheBestSchools.org. That interview forms the core of DDI. Dembski’s forthright and humbly restrained responses reveal the courage, perseverance, and original thinking that have made him a lightning rod in the scientific community. The heated controversy surrounding intelligent design theory dramatically confirms Machiavelli’s observation that there is nothing more difficult to carry out nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things. DDI introduces readers to one of the stellar lights of the new order of things now emerging on the horizon.
I'm speechless.


Why Do University Press Releases Continue to Spread Misinformation?

There's a very interesting paper that's just been published online in ScienceExpress. The work is by Haung et al. (2013) from the Broad Institute at Harvard and MIT (Boston, Massachusetts, USA). These workers looked at the genomes of 70 different malignant melanomas and discovered that fifty (50) of them had mutations in the promoter region of the gene TERT (telomerase reverse transcriptase). The mutations created a new binding site for transcription factors resulting in a 2-4 fold increase in transcription of the gene.

Here's a picture of the gene from the Ensembl website [TERT]. The position of the transcription start site (P) is shown and the approximate position of the two mutations (M) is just upstream.


It's good that mutations affecting melanomas have been identified but the result isn't totally unexpected. We've known for fifty years that mutations in the promoter regions of genes can affect expression. Even in humans, such mutations have been widely studied; for example, lactase persistence is due to mutations in enhancer regions of the lactase gene.

Let's look at the press release from the Broad Institute [Genomic "dark matter" yields major melanoma discovery]. It's written by Paul Goldsmith who writes ...
"This new finding represents an initial foray into the 'dark matter' of the cancer genome," said Levi Garraway, senior associate member of the Broad, and associate professor of medicine at Dana-Farber, the article’s senior author.
WTF! Since when have promoters and enhancers been called "dark matter"? And why isn't it mentioned, or even hinted at, in the published paper?
Only about 1% of the human genome provides the blueprint for the body’s proteins. The remaining "non-coding" portion of the genome, sometimes referred to as dark matter, is poorly understood. Scientists have only recently begun exploring the relationship between these regions and the body’s cellular structure and processes.
We have an excellent understanding of the human genome [What's in Your Genome?]. This press release implies that only 1% of the genome is understood and the rest is mysterous "dark matter." We've known for decades that most of this DNA is junk (defective transposons). We know about pseudogenes, genes that encode functional RNAs, regulatory regions (including enhancers), introns, centromeres, defective viruses, telomeres, origins of replication, and several other functional parts of the genome.

I don't believe that the senior author of this study, Levi Garraway, actually believes what he is quoted as saying. If it were true then why didn't he put it in the paper? Why is there nothing in the paper about the importance of revealing mysterious "dark matter"?

Why do press releases have to be so misleading?

IDiot Quote of the Day

This is for all of you who really miss Saturday morning cartoons. It's from a post by David Klinghoffer who is upset about the way some people are treating Thomas Nagel [New York Times on Thomas Nagel's "Dangerous Sympathy for Intelligent Design"].
One of the take-aways here is not only the progress ID is making in scientific and general culture, but specifically among liberal thinkers. That makes it a lot harder to pigeonhole us in time-honored Darwinian fashion as right-wing Christian fundamentalists, creationists and the like. This may be the chief source of outrage from the Darwin community. Deprived of that old crutch, these guys will be forced to argue with us and explain in detail why ID, not creationism yet again, is wrong. Of course that's something that most have stubbornly, and tellingly, refused to do.
I have been arguing with these IDiots for over twenty years. They stubbornly, and tellingly, refuse to listen. Isn't that strange?


Coming Soon to a Theater Near You - "The Unbelievers"

I wonder if Richard Dawkins and/or Lawrence Krauss will win an Academy Award?




Not All Atheists Are Skeptics

PZ Myers posted an article last week that was part of an ongoing discussion about the role of atheism in the skepticism movement. The title of his post was: Atheists are skeptics. I covered that debate in an earlier post [Skeptics Must Be Atheists].

Now I want to discuss whether all atheists must be skeptics.

The answer is "no." Atheists are people who don't believe in any god(s). There are millions of atheists all around the world who have grown up without any belief in god(s). Their parents didn't believe, their grandparents didn't believe, and they live in a secular culture. Many of these atheists are taken in my homeopathy, fear of GMOs, and various conspiracy theories. They aren't critical thinkers and they aren't skeptics.

Let's not fall into the trap of assuming that all atheists have grown up as believers and have recently lost their faith. That's just not accurate.
