The University of Toronto is sponsoring a "science" festival with three talks tomorrow and Saturday. You have to buy tickets at: tickets.
There's two technology talks and one science talk. I'm going to the only science talk at the science festival. There are a bunch of other things going on, see the entire program.
Friday, Sept. 27th 7pm– "Human Exploration of Space: 50 Years and Counting": Space Shuttle veteran and first Canadian on board the International Space Station, Julie Payette
“High achiever” barely begins to describe Julie Payette. Masters degree in engineering, pilot, IBM engineer, Officer of the Order of Canada, singer with symphonies in Montreal, Toronto, and Switzerland, conversant in six languages, and now Director of the Montreal Science Centre. Oh, did we mention she was orbiting the Earth, using a giant robot arm to build a space station by the time she was 35? Julie will kick off the festival by sharing her unique insights into the past, present, and future of human space exploration.
Friday, Sept. 27th 8pm– "Brave Genius: Jacques Monod, Chance, and our Place in the Universe": Evolutionary biologist and “evo devo” pioneer, Sean Carroll
Biologist and Nobel Laureate Jacques Monod once remarked that “the most important results of science have been to change the relationship of man to the universe, or the way he sees himself in the universe.” Discoveries in molecular biology, evolutionary biology, and geology over the past half-century have profoundly reshaped our picture of human origins, and revealed the enormous role of chance in the fate of life on Earth. Join evolutionary biologist Sean Carroll as he chronicles some of those discoveries through Monod’s eyes, whose own ascent from struggling graduate student to leader within the French Resistance, co-founder of molecular biology, and emergence as a public figure and leading voice of science involved a great deal of chance, and courage.
Saturday, Sept. 28th 7pm– "Postcards from Mars": Mars rover imaging scientist, Jim Bell
Don’t worry if your application to live on Mars was rejected. You can still visit the Red Planet through the spectacular imagery captured by a trio of Mars Rovers—Spirit, Opportunity and Curiosity. Planetary scientist Jim Bell was instrumental in developing cameras and processing images from the three robotic explorers and in his talk “Postcards from Mars”, he’ll share his favorite vistas of our planetary neighbour with you. Through the beauty of these photographs, you’ll see why Bell can be described as a scientist, an explorer and a nature photographer.
Chris DiCarlo talked about fallacies in our class today. We're trying to teach students how to recognize the most important logical fallacies that they are likely to encounter in debates and discussions. He also talked about the importance of consistency and how being caught out as a hypocrite can be devastating to your cause.
Speaking of hypocrisy, the Popular Science website has just banned comments. Apparently they were getting overwhelmed with crackpots and kooks [Why We're Shutting Off Our Comments].
A politically motivated, decades-long war on expertise has eroded the popular consensus on a wide variety of scientifically validated topics. Everything, from evolution to the origins of climate change, is mistakenly up for grabs again. Scientific certainty is just another thing for two people to "debate" on television. And because comments sections tend to be a grotesque reflection of the media culture surrounding them, the cynical work of undermining bedrock scientific doctrine is now being done beneath our own stories, within a website devoted to championing science.
There are plenty of other ways to talk back to us, and to each other: through Twitter, Facebook, Google+, Pinterest, livechats, email, and more.
That's not hypocritical. The hypocrisy comes from Uncommon Descent where someone names "nullasalus" blogged about the Popular Science decisions [Popular Science shuts down comments, citing the presence of dissent from the scientific consensus]. Here's what he/she/it said
Science is not what’s being championed at Popsci.com, nor is ‘bedrock scientific doctrine’ challenged by dissent. Consensus is. Orthodoxy is. Likewise, being ‘politically motivated’ with regards to science is not a problem – it is having political, social and even religious views that PopSci has decided are unacceptable. Dialogue and discussion is welcomed by the self-appointed champions of science – if and only if it results in an outcome they favor. If they suspect it doesn’t, then the dialogue and discussion is over.
Why, it’s almost as if science was never really the concern to begin with.
I was going to make a comment but I can't because I've been banned. Apparently the people at Uncommon Descent have decided that my views are unacceptable. I also can't make any comments over on Evolution News & Views because they don't allow comments.
That's what hypocrisy looks like.
Bradley Monton is a Professor in the Department of Philosophy at the University of Colorado at Boulder. On his website he says he specializes in the philosophy of time, philosophy of religion, philosophy of science (especially physics). He doesn't appear to have any expertise in biology or evolution but he's interested in Intelligent Design Creationism.
A few years ago (2009) he published a book with a provocative title: Seeking God in Science: An Atheist Defends Intelligent Design. Normally I wouldn't pay much attention to such a book but Salvo magazine ("Society, Sex, Science") just published an interview with him [Beyond Belief (or the Lack Thereof)]. It ain't pretty.
Last week's molecules were guanine and adenine. Everyone should have known these structures but only undergraduate Zhimeng Yu got it right! [Monday's Molecule #215].
You probably didn't memorize the structure of this week's molecule but you should be able to recognize it and check your answer in a textbook or on the web. What it is it? (I don't know why it has a gray background. Can anyone help? Fixed.)
Email your answers to me at: Monday's Molecule #216. I'll hold off posting your answers for at least 24 hours. The first one with the correct answer wins. I will only post the names of people with mostly correct answers to avoid embarrassment. The winner will be treated to a free lunch.
There could be two winners. If the first correct answer isn't from an undergraduate student then I'll select a second winner from those undergraduates who post the correct answer. You will need to identify yourself as an undergraduate in order to win. (Put "undergraduate" at the bottom of your email message.)
I finally got to take the quiz at Dialect Quiz & Survey. The server is often overloaded and answering the 140 questions takes more than one hour because of the slow server.
My dialect is most like that of Buffalo NY, which is hardly a surprise since it's the closest American city to Toronto. (I grew up in Ottawa but I don't have much of an Ottawa Valley accent.)
I've been dealing with Intelligent Design Creationists for over twenty years. I've spent a lot of time addressing their scientific misconceptions and trying to explain where they've gone wrong. A few years ago, for example, I posted a whole series of article on Jonathan Wells' book The Myth of Junk DNA. A few weeks ago I explained why Jonathan McLatchie was wrong about pseudogenes.
Lately, I been focusing on one of the chapters in Darwin's Doubt—it's the one on molecular evolution and I know something about that subject. It has been pretty easy to show why Mayer is wrong about his conclusions.
That's why it's so frustrating to read what journalist Tom Bethell said the other day on Evolution News & Views (sic) ["What Is the World Really Like?" Darwinism, Materialism, and How They Relate].
The explicit materialism of the Darwinians is the mirror image of creationism. Creationists are easy for scientific materialists to rebut, because the materialists can say, "That is just your belief. We don't have to accept that." In a parallel way, we can say to the materialists: "That is just your belief. We don't have to accept that. And it is the real basis of your evolutionism."
In between the Creationists and the Materialists we encounter the scientific evidence that makes the materialist position increasingly improbable -- the evidence that Stephen Meyer recently presented in Darwin's Doubt: information theory, insufficiency of the fossil record, epigenetics, complexity of life at the molecular level, and so on.
Increasingly, it seems to me, the Darwinians are responding to this science by saying (in effect): "Bah! We won't read that! It's creationism in disguise." They get graduate students like Nick Matzke, or incompetents like John Farrell (in National Review of all places), to do the work for them. All along the Darwinists have found that their materialism has allowed them to lie back and relax without really bothering to study the evidence.
Now that may be changing. They are being put in a position where they just might have to hit the books. I suspect it is not a prospect that they relish.
Keep in mind that this is written by a man who denies that humans cause global warming and denies that HIV causes AIDS.
He has no idea what evidence looks like.
You've probably noticed that in addition to being stupid most IDiots are not very respectful of scientists (i.e. Darwinists). William J Murray1 explains why religious people have to be mean and nasty [Can We Afford To Be Charitable To Darwinists?].
I used to be one that diligently attempted to provide Darwinists charitable interaction. I tried not to ridicule, demean, or use terms that would cause hurt or defensive feelings. My hope was that reason, politely offered, would win the day. My theistic perspective is that returning the bad behavior I received at sites like TSZ would be wrong on my part. I thought I should stick to politely producing logical and evidence-based exchanges, regardless of what Darwinists did. I note that several others here at UD do the same. Lately, however, I’ve come to the conclusion that what I’m attempting to do is the equivalent of bringing a knife to a gun fight; polite reasoning with Darwinists, for the most part, is simply setting up our own failure. It’s like entering a war zone with rules of engagement that effectively undermine a soldier’s capacity to adequately defend themselves, let alone win a war. While pacifism is a laudable idea, it does not win wars. It simply gives the world to the barbarians.
And that’s the problem; a lot of us don’t realize we’re in a war, a war where reason, truth, religion and spirituality is under direct assault by the post-modern equivalent of barbarians. They, for the most part, have no compunction about lying, misleading, dissembling, attacking, blacklisting, ridiculing, bullying and marginalizing; more than that, they have no problem using every resource at their means, legal or not, polite or not, reasonable or not, to destroy theism, and in particular Christianity (as wells as conservative/libertarian values in general). They have infiltrated the media, academia and the entertainment industry and use their influence to generate narratives with complete disregard for the truth, and entirely ignore even the most egregious barbarism against those holding beliefs they disagree with.
Wars are what happen when there is no common ground between those that believe in something worth fighting for. There is no common ground between the universal post-modern acid of materialist Darwinism and virtually any modern theism. There is no common ground between Orwellian statism-as-God and individual libertarianism with freedom of (not “from”) religion. There is only war. One of the unfortunate problems of war is that certain distasteful methods must be employed simply because they are the only way to win. In this war, in a society that is largely a low-information, media-controlled battleground, logic and reason are, for the most part, ineffective. The truth is ineffective because it is drowned out by a concerted cacophony of lies, or simply ignored by the gatekeepers of low-information infotainment. What has been shown effective is the Alinsky arsenal of rhetoric, emotional manipulation, and narrative control.
I would find it distasteful to pick up a gun in a ground war and have to shoot others to defend my family and way of life, but I would do so. Should I not pick up Alinsky’s Rules for Radicals and employ the weapons of my adversaries, if it is the most effective way – perhaps the only way – of winning the cultural war? There comes a point in time where all the high ground offers is one’s back against the precipice as the barbarian horde advances.
I understand where he's coming from. He's a good Christian who advocates "lying, misleading, dissembling, attacking, blacklisting, ridiculing, bullying and marginalizing" because that's what his opponents do. (And because his versions of truth, logic, and reason have proven to be ineffective.)
BTW, did you notice that he forgot to pretend that the Intelligent Design Creationist movement was all about science, not religion? Oops.
Note to William Murray: If you really were trying "not to ridicule, demean, or use terms that would cause hurt or defensive feelings" then why did you call us "Darwinists"?
1. I assumed that he was the Baptist minister but apparently it's a different William J. Murray.
I read everything posted on Uncommon Descent and Evolution News & Views. These are the most important blogs for learning about Intelligent Design Creationism. The posts on those two blogs represent the very best that Intelligent Design Creationism has to offer. Their best minds are behind the posts.
Here, for example, is Denyse O'Leary in action: Turns out some Texas media DID believe Texas bans discussion of evolution.
... epigenetics is to Darwin’s darlings what relativity and quantum mechanics are to Newtonian physics, only worse, much worse. Newtonian physics was useful within its scale. Darwin’s magical mechanism of natural selection is more like phlogiston, which supposedly produced fire the way Darwinism supposedly produces mind from mud.
And if nothing really happens that way, what becomes of Darwin’s magical mechanism? It’s phogliston, the substance that need not exist!
Seriously, that's the best of the best?
You have to imagine that there are some Intelligent Design Creationists with a modicum of intelligence. Why aren't they speaking up to muzzle people like Denyse O'Leary? She's an embarrassment to their cause.
Stephen Meyer is promoting the idea that God made all the various types of animals over a short period of time about 530 million years ago. The molecular data refutes that speculation because it shows that the various phyla share common ancestors and many of those ancestors appear long before the Cambrian Explosion.
This data creates a serious problem for the IDiots so they have to discredit it in order to dismiss it. As we've seen in earlier posts, Meyer argues that the molecular data is wrong because: (a) there are no transitional fossils, and (b) different molecular phylogenies do not agree in all detail [see The Cambrian Conundrum: Stephen Meyer Says (Lack of) Fossils Trumps Genes and Stephen Meyer Says Molecular Evidence Must Be Wrong Because Scientists Disagree About the Exact Dates]. He has five anti-evolution arguments altogether [Darwin's Doubt: The Genes Tell the Story?]. The third one is that different genes evolve at different rates.
Yesterday I attended a meeting organized by the Ontario Ministry of Education. The theme was From Great to Excellent: The Next Phase in Ontario's Education Strategy. The idea was to promote widespread consultation before the Ontario government releases its new plan for education reform next year.
I was attending on behalf of my friend Chris DiCarlo who had to be out of town. He (and I) are promoting the concept of critical thinking; specifically, the idea that it needs to be explicitly taught in a high school philosophy course.
The Minister of Education (Liz Sandals) and several of the senior members of her ministry were there. They told us that today's students are facing unprecedented changes and that the Ontario education system has to change in order to cope. They were mostly thinking about technological change and the possibility that today's students would have new types of jobs and careers.
I'm certain that we can improve our education system but I'm not sure it's helpful, or even correct, to focus on the idea that the next generation will have to cope with situations we never faced in the past. If we could show that our existing education system did a pretty good job of preparing students for change then maybe we should turn our attention to problems other than job training and technological innovation?
I'm indebted to Veronica for telling me about this petition. I stole the title of her post: La Place du Crucifix de l’Assemblée Nationale Est dans un Musée.
Sign this petition if you think the crucifix should be removed from the Quebec National Assembly.
Stephen C. Meyer believes that the rapid appearance of complex, primitive, animals in the Cambrian cannot be explained without invoking God. The fact that there are no obvious transitional forms in the fossil record means, to him, that those transitional forms don't exist and God must have created all those primitive animals over a short period of time. Presumably, God then let them evolve naturally for the next 530 million years. (Meyer isn't very clear about this.)
Scientists looked at the molecular data in order to test the hypothesis that the Cambrian animals appeared suddenly in a very rapid radiation. The molecular data did not show such a rapid radiation. The overall pattern was consistent with branching evolution spread out over many millions of years. The diagrams that Meyer shows in his book are similar to the figure shown below from Erwin et al. (2007).
I shuddered when I spotted Razib's latest post in my aggregator [see The Central Dogma goes YouTube]. "Oh, no!" I thought, "Am I going to have to point him to my post on The Central Dogma of Molecular Biology?
Imagine my surprise when I saw that he has a link to the Wikipedia article on the Central Dogma. I said to myself, "This will set him straight because I wrote some of that article."
Oops! The Wikipedia article on the Central Dogma of Molecular Biology has been changed. Apparently I haven't looked at it for nine years since the important change was made by someone named Kierano back on September 15, 2006. Kierano describes himself (in 2011) as a Ph.D. student in bioinformatics.
Here's the opening paragraphs from before Sept. 15, 2006.
The central dogma of molecular biology was first enunciated by Francis Crick in 1958 and re-stated in a Nature paper published in 1970:
The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred from protein to either protein or nucleic acid.
In other words, 'once information gets into protein, it can't flow back to nucleic acid.'
The central dogma is often misunderstood. It is frequently confused with the standard pathway of information flow from "DNA to RNA to protein". There are notable exceptions to the normal pathway of information flow and these are often mistakenly referred to as exceptions to the central dogma.
The standard information flow pathway can be summarized in a very short and oversimplified manner as "DNA makes RNA makes proteins, which in turn facilitate the previous two steps as well as the replication of DNA", or simply "DNA → RNA → protein". This process is therefore broken down into three steps: transcription, translation, and replication. By new knowledge of the RNA processing, a fourth step must be included: splicing.
This has undergone some edits from what I originally wrote but the main idea is there. Strictly speaking, the Central Dogma of Molecular Biology (Crick version) says only that once information gets into protein it can't flow back to nucleic acid. I thought it was important to explain the main misconception; namely, that the Central Dogma means DNA to RNA to protein. This should be referred to as "the standard information flow pathway" or something similar.
The rest of the Wikipedia article talks about transcription and translation which, strictly speaking, are not part of the Central Dogma. However, the misconception is so widespread that many people expect these to be described under "Central Dogma."
The new version posted on Sept. 15, 2006 says ...
The central dogma of molecular biology was first enunciated by Francis Crick in 1958 and re-stated in a Nature paper published in 1970:
The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred from protein to either protein or nucleic acid.
In other words, 'once information gets into protein, it can't flow back to nucleic acid.'
The dogma is a framework for understanding the transfer of information between information-carrying biopolymers, in the most common or general case, in living organisms. There are 3 major classes of information-carrying biopolymers: DNA and RNA (both nucleic acids), and protein. There are 9 possible direct transfers of information that can occur between these. The dogma classes these into 3 general transfers (believed to occur normally in most cells), 3 special transfers (known to occur, but only under abnormal conditions), and 3 unkown transfers (believed to never occur). The general transfers describe the normal flow of biological information: DNA can be copied to DNA (DNA replication), DNA information can be copied into mRNA, (transcription), and proteins can be synthesized using the information in mRNA as a template (translation).
The central dogma is occasionally misunderstood as being a statement of absolute fact. If taken as such, it can be criticised, as there are well-described exceptions. It is also criticised by some systems biologists as being too reductionist.
This is the beginning of a change in emphasis. Kierano removed my statement that the basic meaning of the Central Dogma is often misunderstood. It's clear that he misunderstands it.
On March 10, 2012 someone named Nbauman addd the following statement; "Or, as Marshall Nirenberg said, 'DNA makes RNA makes protein.'" Nbauman cautioned that this was a reliable published source and should not be removed from the Wikipedia article. As far as I can tell Nbauman is not a scientist and has no training in science. In fact, she seems proud of the fact that she is ignorant of the subjects she edits. She does not seem to have noticed that her "authority" (Nirenberg) conflicts with another authority (Francis Crick).
Here's the complete version as of this morning. It's going to change as soon as I get around to it.
The central dogma of molecular biology is an explanation of the flow of genetic information within a biological system. It was first stated by Francis Crick in 1958[1] and re-stated in a Nature paper published in 1970:
The central dogma of molecular biology deals with the detailed residue-by-residue transfer of sequential information. It states that such information cannot be transferred back from protein to either protein or nucleic acid.
Or, as Marshall Nirenberg said, "DNA makes RNA makes protein."[3]
To appreciate the significance of the concept, note that Crick had misapplied the term "dogma" in ignorance. In evolutionary or molecular biological theory, either then or subsequently, Crick's proposal had nothing to do with the correct meaning of "dogma". He subsequently documented this error in his autobiography.
The dogma is a framework for understanding the transfer of sequence information between sequential information-carrying biopolymers, in the most common or general case, in living organisms. There are 3 major classes of such biopolymers: DNA and RNA (both nucleic acids), and protein. There are 3×3 = 9 conceivable direct transfers of information that can occur between these. The dogma classes these into 3 groups of 3: 3 general transfers (believed to occur normally in most cells), 3 special transfers (known to occur, but only under specific conditions in case of some viruses or in a laboratory), and 3 unknown transfers (believed never to occur). The general transfers describe the normal flow of biological information: DNA can be copied to DNA (DNA replication), DNA information can be copied into mRNA (transcription), and proteins can be synthesized using the information in mRNA as a template (translation).
Darwin's Doubt is a book about the problems surrounding the Cambrian Explosion. It's written by a prominent Intelligent Design Creationist and, like most books by IDiots, the main theme is how scientists get everything wrong.
The "problem" is how to account for the very rapid appearance of complex animals about 530 million years ago. Intelligent Design Creationists think that they can ignore all of the evidence for evolution for the following 530 million years and focus on this one problem to discredit naturalistic explanations for the history of life.
You might expect that they would offer an alternative explanation. Like, perhaps, an intelligent being who visited Earth 530 million years ago, created a bunch of different animals with similar body plans, then allowed evolution to proceed for the next half a billion years?
Don't hold your breath waiting for a scientific explanation. They aren't that clever.
