Men And Their Members
Mark Hoofnagle, over at denialism blog, has a wickedly good post on the eternal search by the male of the species for tumescence. I particularly liked the lengths (as it were) that British physiologist Giles Brindley went to in order to demonstrate the efficaciousness of his research. Egad, sir, we British are afraid of nothing in the pursuit of scientific truth… -

Orac At The Gates
Orac is the pseudonym of an American surgeon/scientist who has an informative blog. He’s currently visiting London, and had to see the Royal London Homeopathic Hospital for himself. He is, as you might expect, no fan of homeopathy, and uses this blog entry to flense the criticisms of homeopaths to Richard Dawkins recent look at homeopathy on The Enemies of Reason. Very entertaining.Oh, and while we’re on the subject of homeopathy, there’s a new book coming out next month, The Homeopathic Revolution, written by Dana Ullman MPH. One thing that is intriguing is Ullman’s claim that:"Charles Darwin could not have written Origin of Species without the homeopathic treatment that he received from Dr. Gully (based on Darwin’s own letters!)."It sounds almost as though Darwin was helped by homeopathy, doesn’t it? And that’s the spin that is already being put on it by some homeopaths. Unfortunately, the truth is somewhat different. Darwin was skeptical of homeopathy – and this is seen in his letters (which are online). The tipping point, as pointed out by Andy Lewis over at The Quackometer, may have been related to homeopathy, but not in a good way:The truth is that homeopathy may have played a pivotal role, but only in its utter failure to save the life of Darwin’s precious daughter. Darwin was torn with doubts whilst working on his theory about the effect it would have on his wife, who was devout, and on the religious authority and structures in society in general. Having his own faith ripped away was an important removal of a barrier to publication.If Ullman is going to claim in his forthcoming book that Charles Darwin was helped by homeopathic medicines to overcome the illnesses that plagued him for much of his life so that he could write Origin of Species, then this would seem to be yet another example of homeopaths cherry-picking the evidence to prove their case. They may think they are arguing a posteriori when in fact they are simply demonstrating a priori reasoning. -
Making Slime
When I was young, I was fascinated by odd materials such as Potty Putty and Slime. If you’re interested, here’s chapter and verse on how to make your own Slime… -
The Amazing Randi
The very wonderful and Canadian National Treasure known as James Randi recently paid a visit to Google HQ where his stream of consciousness was videoed. -
Pepys’ Slide-rule
I didn’t know, but apparently Samuel Pepys was a 17th century geek; besotted with his slide-rule. I learn something new every day. -
Dancing Robot
The Japanese continue their fascination with all things robotic with this one, demonstrating its prowess at traditional dance. I doubt whether it could do Hip-Hop…More about the background here. -
A Late Night Tonight
Oh dear, it looks as though I’ll have a late night tonight. First up is Dangerous Knowledge on BBC Four, starting at 23:05. The documentary will look at the work and lives of three brilliant mathematicians and an equally brilliant physicist: Georg Cantor, Ludwig Boltzmann, Kurt Gödel and Alan Turing. And then at 00:35 tomorrow morning is another chance to see Derek Jacobi in Breaking the Code, which is an excellent film adaptation of the stage play about Alan Turing.Black coffee and matchsticks at the ready… -
Murata Boy
Murata Boy is a bicycle-riding robot. It actually rides a bike better than most humans – I can’t come to a dead stop and still remain upright, for one thing. Still, Murata Boy cheats – I think it doesn’t actually power the bicycle with its feet – there’s what looks suspiciously like an electric motor attached to the rear wheel. Same for the handlebars – I think they are turned by a servo motor in the top of the frame. Despite this, Murata Boy is pretty impressive. It was created to showcase the technologies of the firm that built it. -
Bootstrapping The Brain
Carl Zimmer refers to an article that appears in Nature, which describes the case of a man being roused from a minimally conscious state by electrical stimulation of his brain. Unfortunately, the article is available to subscribers only, so I haven’t been able to read it. But Zimmer does have a link to an article that he wrote on the background. And here’s a BBC news story on the current development (pun not intended). -
Atom
The BBC seems to have hit its stride again with some excellent science documentaries. After the appalling decline of Horizon, once the flagship of BBC science documentaries into dumbed-down crap produced by meeja-studies graduates, it comes as something of a relief to be able to say that the Science You Can’t See season on BBC Four is shaping up very well. After two reasonable programmes on the quest for Absolute Zero, I’ve just seen the first of three programmes on the science of the atom.I’m impressed. Presented by Professor Jim Al-Khalili, this is science that is not dumbed-down in the slightest. And we didn’t have any of those appalling "reconstructions", with actors hamming it up. Instead we got documentary footage of the real people involved – most memorably of the amazing conference at Solvay, with Einstein and Bohr representing the opposing sides, and duking it out with their theories.The fifth Solvay conference formed the climax of the first of Al-Khalili’s programmes, and he literally walked us through the famous photograph of the attendees at the conference, to great effect. Then we suddenly cut from the conference building in Brussels to the good professor standing in an Alpine meadow. For one dizzy moment, I felt sure that he was about to do a Julie Andrews and burst into song, but no; he simply set up the next episode, which I can’t wait to see. Very good stuff indeed. It clearly helps to have someone who knows his stuff, and who is a great communicator, to front up a science programme like this.I’m also greatly looking forward to another programme in the season: Dangerous Knowledge, which will include the life and work of Alan Turing. -
Not Just A Theory
I often read statements to the effect that "evolution is just a theory…", usually written by an American, but also (depressingly) increasingly by Europeans. It’s a statement that is a sure sign of ignorance. The writer, either genuinely, or disingenuously, does not realise that the word "theory" has a special significance in the scientific method.
Here’s a short, pithy primer on the scientific meaning of the word.

A Scientific Spat
Richard Dawkins seems to attract more than his fair share of unfounded attacks, and not always from the other side of the religious dialogue’s divide. Here, for example, is David Sloan Wilson, atheist and Distinguished Professor in the Departments of Biology and Anthropology at Binghampton University, writing in a recent article of eSkeptic:
When Dawkins’ The God Delusion was published I naturally assumed that he was basing his critique of religion on the scientific study of religion from an evolutionary perspective. I regret to report otherwise. He has not done any original work on the subject and he has not fairly represented the work of his colleagues.
Er, excuse me? I can almost see Wilson perched on top of his high horse in a state of affront. Dawkins has responded entirely reasonably, I feel:
Why would Wilson ‘naturally assume’ any such thing? Reasonable, perhaps, to assume that I would pay some attention to the evolution of religion, but why base a critique on an evolutionary perspective, any more than on Assyrian woodwind instruments or the burrowing behaviour of aardvarks? The God Delusion does, as it happens, have a chapter on the evolutionary origins of religion. But to say that this chapter is peripheral to my main critique would be an understatement.
…
The central theme of the book is the question of whether God exists. I agree that it is also interesting to ask whether religion has some kind of Darwinian survival value. But whatever the answer to that might turn out to be, it will make no difference to the central question of whether God exists.
Wilson also can’t resist an ad hominem attack on Dawkins:
Time will tell where Dawkins sits on the bell curve of open-mindedness concerning group selection in general and religion in particular. At the moment, he is just another angry atheist, trading on his reputation as an evolutionist and spokesperson for science to vent his personal opinions about religion.
This probably accounts for the fact that methinks I detect a slight sense of exasperation, and I can’t say I blame him, in Dawkins’ reply when he writes that he even refers the readers of The God Delusion to the work of Wilson:
As for group selection (either as normally understood or in the idiosyncratic sense of Wilson’s private re-definition, about which he has been obsessing for thirty years), The God Delusion devotes a sympathetic page and half to the possibility that something like it might apply to the special case of religion. But a page and a half was all I could spare because I had more interesting matters to talk about, for example the "moth in the candle flame" theory of the origins of religion. I referred my readers to Wilson for a fuller treatment of what he calls group selection, and moved on. I thought it a generous gesture at the time, and I see no reason now to regret my choice to write my own book rather than his.
I would just like to make a couple of further points. The first is that much of Wilson’s article in eSkeptic is most interesting, and worth reading in its own right. But I do note that Wilson has received funding from the Templeton Foundation for some of his research, which I personally find somewhat questionable. That seems to me to be rather like research into astrology being funded by those who have a stake in proving that astrology works. One should not be surprised to see that the result is often bad science to produce the required result. A charge of using the language of statistics in a misleading manner is also being levelled at some of Wilson’s findings.
Here’s an article that states that Wilson has received funding from the Templeton Foundation and it is also indicative of why I am suspicious of such foundations and those associated with them. It’s an article by William Grassie, founder and former executive director of the Metanexus Institute on Religion and Science and who managed the Templeton Advanced Research Project. He opens the article with:
Noted philosopher Daniel Dennett recently published a book entitled Breaking the Spell: Religion as a Natural Phenomenon, arguing for the necessity of engaging in the scientific study of religious and spiritual phenomena.
The John Templeton Foundation shares with Dennett the conviction that the scientific study of religious and spiritual phenomena is a wholesome and worthwhile endeavor and has done much in the last decade to promote such research. However, for Dennett the assumption at the outset is that there is no truth-value in religion and that the result of this inquiry will be the disenchantment of religion. The Templeton Foundation’s approach is to assume, indeed, that there is truth and other value to religion. God, by whatever name, exists. Humans can learn a lot more about themselves and also something more about ultimate reality by appropriately studying and interpreting religious traditions with the help of science, including the human sciences.
I have a couple of issues with this. The first is the statement that "Dennett has the assumption at the outset that there is no truth-value in religion and that the result of this inquiry will be the disenchantment of religion". This is simply not true. Grassie is either deliberately or inadvertently being extremely economical with the truth. Dennett has quite clearly written in Breaking the Spell, and gone on record in interviews, that he, himself, simply does not know:
Wouldn’t such an exhaustive and invasive examination damage the phenomenon itself? Mightn’t it break the spell? That is a good question and I don’t know the answer. Nobody knows the answer. That is why I raise the question, to explore it carefully now, so that we (1) don’t rush headlong into inquiries we would all be much better off not undertaking, and yet (2) don’t hide facts from ourselves that could guide us to better lives for all.
For Grassie to state at the outset that, in effect, he knows the answer, simply underlines to me why I am suspicious of such foundations and their "research". I’ll leave the last word to Dennett:
Who is right? I don’t know. Neither do the billions of people with their passionate religious convictions. Neither do those atheists who are sure the world would be a much better place if all religions were extinct. There is an asymmetry: atheists in general welcome the most intensive and objective examination of their views, practices and reasons. (In fact, their incessant demand for self-examination can become quite tedious.) The religious, in contrast, often bristle at the impertinence, the lack of respect, the sacrilege, implied by anybody who wants to investigate their views. I respectfully demur: there is indeed an ancient tradition to which they are appealing here, but it is mistaken and should not be permitted to continue. This spell must be broken and broken now. Those who are religious and believe religion to be the best hope of humankind cannot reasonably expect those of us who are skeptical to refrain from expressing our doubts if they themselves are unwilling to put their convictions under the microscope. If they are right – especially if they are obviously right, on further reflection – we skeptics will not only concede this but enthusiastically join the cause. We want what they (mostly) say they want: a world at peace, with as little suffering as we can manage, with freedom and justice and well-being and meaning for all. If the case for their path cannot be made, this is something that they themselves should want to know. It is as simple as that. They claim the moral high ground; maybe they deserve it and maybe they don’t. Let’s find out.

Captain Jack Visits CERN
Actor John Barrowman (aka Captain Jack) visits CERN to learn about the Large Hadron Collider. Here’s the podcast and here’s the vidcast. The podcast is much more meaty as far as science goes, but if you want to see Captain Jack in a hardhat, then by all means watch the vidcast. Unfortunately, there’s some really irritating music on the vidcast as well, so you will have to put up with that…The moment in the podcast when Dr. Brian Cox asks Barrowman what sort of quark he would like to be is classic (hint: the choices include such flavours as top or bottom).I see that there’s also a podcast with Charles Jencks – I must listen to that as well. -
The Power Of Memes
The wonderful Dan Dennett talks about ants, terrorism and the power of memes… Recorded back in 2002 at a TED conference, it’s only just been posted on the TED web site. I can do little better than to echo the byline on the site’s page: This. Is. Unmissable. -
Binaural Recording
If you’ve got a pair of headphones handy, then use them to listen to this sound recording. It’s been recorded binaurally, rather than stereophonically. That means that the aural illusion is very strong indeed. Just listen.(hat tip to PZ Myers) -
When Tim Met Jim
A good article in the Observer about the continuing gulf between art and science. It worries me that so many of the scientific facts that I had at my fingertips when young are beginning to slip away from me now. Time for a refresher course, I think.But perhaps even more worrying is the fact that ignorance about science seems to be on the rise. -
Before The Bang
Phil, over at the Bad Astronomy Blog, writes about some of the very latest research theories that are coming out about what may have been going on when time started and maybe even before it started. Fascinating. -
It Is With Some Trepidation…

A procedure (medical and/or religious) that’s been around for at least 7,000 years.
