With a hat tip to our friend Jess, here is a link to a post at the science blog Gene Expression that reports a result which, if true, is hardly a surprise.
So caught up was I in holiday-weekend bacchanalia that I almost neglected to note that the Phoenix Mars Lander made a successful descent in the Red Planet’s north polar region yesterday. “For the first time in 32 years, and only the third time in history, a JPL team has carried out a soft landing on […]
A couple of days ago I linked to Steven Pinker’s discussion of the recent report by the President’s Council on Bioethics, and mentioned that one of the contributors, surprisingly given the overall makeup of the Council, was the irreligious and materialist philosopher Daniel Dennett. In his essay, he is in fine, feisty form.
Steven Pinker, writing in The New Republic, takes aim at The President’s Council on Bioethics for mulish opposition, on largely theological grounds, to a variety of promising medical and scientific efforts.
For those of you who don’t know, our friend Kevin Kim has a new website, created for the purpose of chronicling his upcoming transcontinental walk — a trek whose purpose is to explore the many parallel currents of religion in America, and if possible to help build bridges between them. The walk itself won’t get […]
My daughter ChloÁ« has sent along a link to an article about Piotr Wozniak, the inventor of SuperMemo, a software application that uses some neglected facts about the workings of human memory to help users retain more of what they learn. The system is designed to remind users at specific intervals of items they have […]
It’s already well-known that affluence and education are positively correlated with any number of desirable outcomes: longevity, general health and happiness, that sort of thing. Now we find that it not is only disadvantageous to be poor and ignorant, it hurts. Story here.

We note with sadness the death of this great scientist. He was one of the giants of 20th century physics, and mentor to an extraordinary assortment of disciples. His New York Times obituary is here.
Here’s another item from Physorg.com: it appears that there might have been something to the old saying after all.
Since the Big Bang was first proposed as a cosmological model for our universe — a model that has since been accepted with confidence by the astrophysical community — it has been assumed that it might well be impossible in principle to say anything about the state of the world prior to the initial singularity. […]
I tend to be a fairly hard-nosed naturalist, as readers may have noticed. This arises from an inveterate intellectual conservatism: I think that the most parsimonious approach to understanding the world around us is to try to explain the phenomena we observe — the “phaneron”, to use Charles Sanders Peirce’s lovely word — in terms […]
An item in today’s Washington Post informs us that our only hope to avoid total annihilation is to reduce our carbon emissions to zero. Now.

New research has determined that the Earth, barring any manipulation of its orbit on our part, will be consumed by the dying Sun in 7.6 billion years. Experts are divided on whether this will allow sufficient time for the completion of the proposed Second Avenue subway line. Learn more here.

Don’t trade in that gas-guzzling Detroit road boat just yet. The Cassini space probe, which has been buzzing about the Saturn system gathering data, has revealed that the giant moon Titan has hundreds of times more combustible hydrocarbons just lying around on its surface than are in all the known oil and gas reserves on […]

There has been a good deal of excitement lately about global warming, as readers may already have noticed. It having been announced that the cause is an increase in atmospheric carbon dioxide due to human activity, various segments of society have whipped themselves into rather a frenzy, and some of those in the public eye […]

Yesterday I offered readers a link to a video of a thought-provoking conversation (transcript here, video here) between J. Craig Venter and Richard Dawkins (if you haven’t found the time to look at it yet, I do hope you will). In the ensuing thread, however, rather than discussing any of the forward-looking topics that had […]
February 7, 2008 – 12:48 pm
Here’s Richard Dawkins, opening a conversation with J. Craig Venter at a recent conference in Germany: I thought I’d begin by reading a quotation from a famous philosopher and historian of science from the 1930s, Charles Singer, to give an idea of exactly how much things have changed. And Craig Venter is a leader, perhaps […]

Following on yesterday’s post, here’s a story about another gruesome malady: it turns out that meat-processing workers in Minnesota are developing a strange neurological illness as a result of being splattered with atomized hog brains.

NASA’s MESSENGER (Mercury Surface, Space Environment, Geochemistry, and Ranging) vehicle made a close pass by the innermost planet today, executing a gravitational “slingshot” maneuver in preparation for an orbital insertion on on March 18, 2011, after which it will settle in for some long-term observations. As it passed by, it photographed parts of the planet […]

A little while ago I ran across an interesting, if rather sad, item in the Physorg.com daily newsletter, having to do with the small stature of pygmies. Previous notions had been that having such wee bodies better adapted them to food shortages, or to moving about in dense forests, but neither of these explanations has […]

After a truly debilitating holiday bacchanal last night, followed (almost immediately, it seemed) by a long day at work, I’m far too pooped to post. But I do have something interesting for you to read, if you like. Anyone who pays attention to scientific and technological topics (or who reads the little messages generated by […]
November 24, 2007 – 12:20 am
It was a long day at work; I didn’t get home until after ten, and haven’t had time to prepare anything for tonight. But, saving the day, my friend Jess Kaplan has brought an awfully provocative story to our attention. The topic is an exotic one, right at the edges of human knowledge and understanding, […]

I’m still in southern California, and have had no time for writing today. So here is some more Richard Feynman for you. This clip is about ten minutes long, and unfortunately begins in mid-sentence; of particular interest, however, is the section from about 5:15 on, in which he talks about the built-in uncertainty of science, […]

A couple of days ago the Nobel laureate James Watson was all over the news: he had expressed, in an interview for the London Times, his opinion that scientific results indicated that black Africans were, on average, less intelligent than white Northerners. In a subsequent article, we read: Dr Watson, who runs one of America’s […]

My son Nick has sent along a link to a video, in four parts, of a marvelous lecture by Richard Dawkins on the topic of Science, Delusion and the Appetite for Wonder. Dawkins is, of course, a controversial figure nowadays for his staunch criticism of religion, but like him or not he is a brilliant […]

Today’s Physorg newsletter (which, as always, I recommend to those of you who like to keep up with science news) contained a story about what looks to me like an important piece of medical research, involving the role played by tryptophan in cancer and other diseases. Have a look here.
September 14, 2007 – 10:11 pm
From my son Nick, a splendid young man, restless Internet spelunker, and the prop of my dotage, comes a link to what looks like an worthwhile website: The Worlds of David Darling. I’d never heard of the fellow, but according to Wikipedia he is a well-known British astronomer who has written scads of books. Anyway, […]

To do physical science, one needs uniform references for fundamental quantities: length, duration, mass, and so forth. Over time, as the need for accuracy has increased, attempts have been made to place the fundamental units on ever more precise footing. For example, the reference meter, which was declared in 1791 by the French Academy of […]

As one who has taken, shall we say, a rather nonstandard path through life, I’m always gratified to see mavericks and autodidacts come through with the goods, and I’ve just run across a particularly noteworthy example. Inventor John Kanzius, of Erie, PA, who is battling leukemia, has developed a technique, using nanoparticles and radio waves, […]

We are still more occupied with sun and surf than the glowing screen, but will be back in town, with nose reapplied to grindstone, this week. Meanwhile, a rather odd item from the frontiers of astrophysical research: it appears that there is an enormous hole in the visible universe, a billion light-years across. Lately it […]
August 21, 2007 – 4:13 pm
A few days ago we made passing mention of the Oxford philosopher of science Nick Bostrom’s Simulation Argument, which makes the claim that we are probably living in some sort of Matrix-like computer program. This dismal notion, which we looked at a bit more closely back in May, was also the subject of a brief […]

Here’s another interesting item about climate change, sent our way by Mike Zaharee. It appears that some of the data about which of the past hundred years or so have been the warmest may have been a bit off. See this post as well.

Freeman Dyson, one of our greatest living scientists, has always been known for the originality and independence of his thinking. I’ve just read a remarkable essay by this formidable man, and hope you’ll read it too.
Recently blogger Dennis Mangan, the proprietor of Mangan’s Miscellany, offered his readers information suggesting that animal products in the diet are the cause of numerous health woes. It grieves me to offer more grist for his mill on this one, as I am a carnivore’s carnivore ((I’ve even considered attempting a diet that consists solely […]
Those of you with an interest in astronomy, and a fondness for order, might like to take a look here.
Today’s Physorg.com newsletter (which I enthusiastically recommend as an excellent source of news about all branches of science) had an interesting item about social hierarchies in fish. As is so often the case with discoveries of organizing principles in nature, the research is likely to help us understand not just the particular system under examination […]
Each year the website Edge.org — which I will recommend once again to you all, as it is one of the Web’s most stimulating destinations — asks the intellectual community a carefully chosen question, presents the answers on its website, and then gathers them together into a book. Previous questions have included What Questions Are […]
The late Victorian era was a time of smug certainty in the scientific world. The Darwinian revolution had the God of the Gaps on the run, technological innovation was accelerating briskly, and the great intellectual cataclysms of the 20th century — relativity, quantum mechanics, and GÁ¶del’s theorem, foremost among many — were still nothing more […]
From my friend Jess Kaplan comes a link to the text of a 1966 speech by Robert Oppenheimer about Albert Einstein, whom Oppenheimer of course knew for decades. It is a fascinating glimpse into the personality of the great man, and readers are encouraged to take a look. (It is also far less controversial and […]
There’s a quirky little item in the science news today: some researchers in Germany have been studying fruit flies, and have observed that their behavior seems surprisingly flexible.
We will return to weightier matters as soon as time permits, but meanwhile: You may think you know plenty about duck phalluses, but you have nothing on one Dr. Patricia Brennan, who has made the study of the anatine willy her life’s work. Most male birds, in fact, are entirely ajohnsonal, but ducks buck this […]

There’s lots of interesting news these days from really faraway places; if you’re interested in such things, you should subscribe to two of the newsletters I get: one published by NASA, and the other from Spaceweather.com. There are three stories I’ll mention tonight.
In remarking on a recent post, commenter Titus Rivas offered a link to a paper he and Hein van Dongen wrote in 2001, in which they launch an assault on the mind-body model known as epiphenomenalism. Epiphenomenalism is the view that the subjective, conscious mind is a causally impotent byproduct of the physical activity of […]
An item in today’s Times reports a new and important result from a major European research facility. After years of painstaking investigation, the Vatican has announced that Limbo, an area where the souls of unbaptized babies and of the multitudes who lived before the time of Christ were previously understood to dwell — not in […]

The Cassini probe of Saturn has sent back a striking photograph of the planet’s northern polar region, taken in the infrared portion of the spectrum. It reveals a startling feature: an enormous hexagonal standing wave girdling the pole. You’ve never seen Saturn like this. Have alook here.
Readers of these pages will certainly be familiar with Daniel Dennett, the prominent Tufts University philosopher who has done important work over the last several decades on the subjects of free will, evolutionary theory, and, most notably the philosophy of mind. Dennett has also been a major player lately in the increasingly voluble science-vs. religion debate; his book Breaking the Spell is must reading for those who have an interest — from either perspective — in this vital dialogue.
Well, our Dan has been through quite a lot in the past few months; in October he suffered an aortic dissection, and nearly died.
Having, as I do, an interest in matters astronomical, I subscribe to the NASA Science Newsletter (you can, too, by clicking here). Among the other extraterrestrial beats covered by their rovingest of reporters is the violent surface of our Sun.
The newsletter’s latest number carries a fantastic video of a swirling magnetic paroxysm, a vortex of nuclear fire nearly the size of the Earth. Read the story, and see the video, here.
The Jovian moon Io, its small size notwithstanding, is one of the most geologically active objects in the solar system. It is close enough to Jupiter that it is subject to constant tidal stresses, which generate a tremendous amount of heat in the moon’s interior. While most airless moons are scarred and pocked with impact craters, the surface of Io is quite smooth, due to its constantly being paved over with volcanic ejecta. Were Io much closer to Jupiter it would simply be torn apart.
Now the exploratory probe New Horizons, passing by on its way to Pluto, has sent home a remarkable image of an enormous eruption on this tormented moon. You can see it http://science.nasa.gov/headlines/y2007/09mar_alienvolcano.htm?list743573.
Io is a truly remarkable place, unique in many ways. Wikipedia has a good gateway article about this amazing little world; you can find it here.

You may have heard of the book The Structure of Scientific Revolutions, by the late Thomas Kuhn; it is arguably the most influential book ever written on the history and philosophy of science. In it, Kuhn examines the life cycle of a scientific “paradigm”, and the way that scientific communities pass from periods of “normal” science, during which research stays comfortably within the reigning paradigm, to “crises”, in which results begin to appear for which the current model cannot account, and during which more and more desperate efforts are made to preserve the existing view. An example of such a crisis would be the difficulties pre-relativistic physics found itself confronted with in the aftermath of the Michelson-Morley experiment.
Eventually, some breakthrough is made — a “scientific revolution” — and a new model is found that accommodates the troublesome data. Often this involves an entirely different understanding of the phenomena, and even of the nature of reality itself; Kuhn coined the now-familiar term “paradigm shift” to refer to this sort of reformulation.
