COSYNE Day 2: Mormon Temple Square

Many of the talks today were about the molecular mechanics of neurons. Not quite my cup of tea, since I didn't understand much.

I did, however, spend some time at the Mormon Temple Square. The buildings are beautiful. I was amazed to hear that this big chapel was started in 1853, and completed in 1889.


I toured the visitor centre. It was basically divided into 3 parts: (1) the building of the chapel, (2) the words of the modern prophet Thomas Monson, and (3) families.

I watched about 6 of the short sermons given by Thomas Monson, the current president of the Mormon church. He's also considered a prophet.


In one video about raising children, he talked about how early life experiences can affect a person. I was amused when he used phrases like "The evidence reveals..." He accepts scientific evidence when it's convenient, but rejects it if it contradicts his faith.

As I watched him speak, I became aware of the striking contrast between his talk, and the talks I'm attending at the conference. If anyone at the conference makes a claim that goes beyond their evidence, they are promptly called on it. Of course, you might argue that a sermon and a scientific conference are entirely different. But are they? In both cases, the expert is sharing their wisdom with others. The only real difference is that in a scientific conference you're free to question and demand evidence for claims. No so in religion.

I spent some time talking to a couple young lady missionaries; that's what they call the volunteers with the name tags that wander around looking to talk to visitors. One girl was from Ottawa, and she did almost all of the talking.

I asked her if Mormons were encouraged to talk to their peers about their beliefs. She said that they were, and that anyone would want to talk about their passion. I was relieved to hear that, and told her that I consider myself an evangelical scientist. I guess I agree with her on that, at least. So, she tried to talk me into becoming a Mormon, and I tried to talk her into becoming... a secular humanist, I suppose.

I was conscious that she kept us moving away from other visitors.

We basically established that her "evidence" is an emotional knowing, and is subjective. I told her - a number of times - that subjective truths can easily lead to irreconcilable conflicts. When religion A disagrees with religion B, who is right? Science, I continued, is based on objective truth, a reality that we can all agree on and share. She nodded politely. It seems that she prefers her own reality.

In case you're not aware, the Church of Jesus Christ of Latter Day Saints was started by Joseph Smith in 1830. Joseph had a revelation, in which God asked him to transcribe some gold plates into modern English. He was told where to find the plates, buried in New York state. The result was the Book of Mormon, considered by Mormons to be a new testament that rescues the Christianity that had gone off the rails. Disappointingly, the gold plates disappeared and went back to Heaven. The only remaining evidence is the Book, and the signed testimony of 11 witnesses that claim to have seen the plates.

That's a nice story, and might even be true. But I offered a different explanation. Perhaps Joseph Smith decided to start his own religion, so wrote a book and made up a story about it being divinely inspired.

The nice girl had never heard of Occam's razor, but I suggested that my explanation was in many ways more parsimonious... requiring fewer miracles (none, to be exact). That clearly pissed her off. She said, "Yes, even though there are 14 million of us", as if to imply that 14 million people can't be wrong. I said that many religions have lots of followers. I wish I'd thought to say that popularity dos not make something true. Flat earth, for example.

I felt bad for making her mad. I certainly wouldn't expect her to change her mind overnight, since her entire family would probably stage an intervention to reel her back in.

COSYNE Day 1

I'm at a conference in Salt Lake City, Utah. The conference is called Computational and Systems Neuroscience (COSYNE).

What have I learned so far?

That there are many MANY monkeys and mice out there with electrical probes in their brains. The majority of talks so far talk about measurements of neural activity in various regions of the brain, and the subsequent data analysis that tries to make sense of it all in light of the stimulus that caused the activity in the first place.

The first talk was amazing! E.J. Chichilnisky described a project in which they put a piece of a retina on an electrical array (that picks up electrical activity), and shone various configurations of light on the retina. Correlating the input image with the output electrical activity, he was able to isolate the activities of individual cone photoreceptors, as well as how the cones pool their activity for individual retinal ganglion cells - the long, thin neurons that are bundled to form the optic nerve. Basically, elucidating the wiring diagram of the retina, and what image processing gets done in the back of your eyeball. Cool.

I also learned that the visitors' centre of the Mormon Temple (The Church of Jesus Christ of Latter Day Saints) is open from 9am to 9pm. The "sisters" that I spoke to were very friendly. I'm really curious to check it out, and find out what makes these people tick. I think I'll spend an hour or so tomorrow looking around and asking questions.


One more thing. I got a kick out of Chichilnisky's talk when he said that his "focus was on the retina".

Homeopathetic logic

It's so cute when homeopaths try to talk all sciency. This web page tries to offer responses to common challenges to homeopathy.

Here's the challenge...
Argument #3: There is no scientific proof from placebo controlled human trials that homeopathy is effective therefore homeopathic remedies are nothing but a placebo.
And the response...
Rebuttal #3: Placebos are by far the best studied medicines. Their benefits have been evaluated and proven in every placebo controlled study ever conducted. Placebos definitely have an effect; in fact they have become the standard by which all pharmaceutical are compared. ...
How can you test the efficacy of a placebo in a placebo-controlled study? It's like saying you can fly by pulling up on your bootstraps.

But let's not lose sight of the most glaring issue. To quote the Homeopathy Evidence Check from the British House of Commons,
In our view, the systematic reviews and meta-analyses conclusively demonstrate that homeopathic products perform no better than placebos.

Free hotel

I just booked my hotel for the conference ICIAM. What a bargain! Here's the confirmation page.


Indeed, I had to enter my VISA number to pay $0. Hmm... somehow this seems too good to be true. I'll wait a bit, and then call to confirm the reservation.

Reverse Speech: Hear what you want to hear


That's the title of my latest SkepticNorth blog post. Check it out.

Numerology in the Quran

Some claim that numerology is proof that the Quran is the divine word of Allah. Here is a sampling of the evidence (taken from here):

  • The statement of “seven heavens” is repeated 7 times. “The creation of the heavens (khalq as-samawat)” is also repeated 7 times.
  • The word “Day (yawm)” is repeated 365 times in singular form, while its plural and dual forms “days (ayyam and yawmayn)” together are repeated 30 times.

Those are kinda neat, but would be trivial to implement. It's a shame that the word "Day (yawm)" couldn't be repeated exactly 365.256363 times.

Now for the amazing number 19!! Again, just a sampling:

  • The first verse of every sura (chapter) known as “Basmalah” (bismillah al-rahman al-rahim) consists of 19 letters.
  • The Quran consists of 114 suras, which is 19 x 6.
  • The total number of verses in the Quran is 6346, or 19 x 334.
  • 6234 numbered verses & 112 un-numbered verses (Basmalahs) 6234+112 = 6346. Note that 6+3+4+6= 19.
  • The Basmalah occurs 114 times, despite its conspicuous absence from Sura 9 (it occurs twice in Sura 27) & 114= 19 x 6.
  • The Zakat charity is mentioned in [a number of verses that] add up to 2395. This total does not quite make it as a multiple of 19; it is up by 1.
    The Hajj Pilgrimage occurs in 2:189, 196, 197; 9:3; and 22:27. These numbers add up to 645, and this total does not quite make it as a multiple of 19; it is down by 1.
    Thus, Zakat and Hajj, together, give a total of 2395+645 = 3040 = 19×160.

  • ... yadda yadda yadda ...

The list goes on and on, quoting many MANY quantities that are divisible by 19.

It occurred to me that every 19th number is divisible by 19.

Moreover, suppose you have 100 different quantities that you tabulate in a document (eg. number of chapters, or times a word is used). If you consider all possible combinations of those quantities, you'll get about 1030 values. In combinatorial notation, that’s

   (100 choose 1) + (100 choose 2) + … + (100 choose 100).

If one out of every 19 of those is divisible by 19 (as one would expect), then you’re left with more than 1028 “coincidences”… combinations of quantities that are divisible by 19. In fact, there will be a comparable number of “coincidences” for 15, 16, 17, 18, 20, 21, etc.

These numerology "miracles" are statistically unimpressive, and certainly not proof that the Quran is the divine word of Allah.

Mohammed vs Jesus


I'm taking part in a little online convo over at Extraordinary Claims. The entry on Allah has quite a few comments. In the latest round, I couldn't help noticing the Quran talking smack about Jesus. In one comment, commenter "atom" includes a litany of quotes from the Quran. Allah drones on about those who reject his revelations, "We will make his punishment long and terrible." [19:79] Blah blah blah.

But this seems a little unfair...
Those who deny Our Revelations are deaf and dumb, living in many layers of darkness. Allah confounds whom He wills, and guides to the Right Way whom He pleases. [6:39] ... Those who deny Our revelations, We draw them step by step closer to destruction in ways that they do not realize,[7:182] and even though I grant them respite; My plan is surely effective.[7:183] ... None can guide those whom Allah confounds and leaves them blundering about in their rebellious transgression.[7:186]
Oh great! So, not only am I going to hell, but no one can stop me, not even myself. That's not fair.

I managed to stay awake long enough to come across the text,
Those who say: “The Compassionate (God) has begotten a son,” certainly preach such a monstrous falsehood,that the very Heavens might crack, the earth might cleave asunder and the mountains might crumble to pieces – at their ascribing a son to the Compassionate (God), It is not befitting to the Compassionate (God) that He should beget a son.[19:88-92]
Soooo... I guess Jesus is out of the question. Couldn't help wondering what the Christians might have to say about that. And it seems that the New Testament is not an "enlightening Book",
Yet there are others among people who wrangle about Allah, though they neither have knowledge nor guidance, nor an enlightening Book, twisting things around in order to lead others astray from the Path of Allah – for such persons there is disgrace in this life, and on the Day of Judgment we shall make them taste the punishment of burning fire,[22:8-9]
Oh good, so it's not just me, but all Christians too.

Hmmm... which religion is right? Which one should I choose?

NEITHER!
