“Science is the refuge of the mediocre”: Steve Jones on “The Life Scientific”

August 7, 2012 • 4:17 am

My friend Steve Jones (real name John Stephen Jones), geneticist and popular writer, appeared this morning on the BBC Radio 4’s regular program, “The Life Scientific.” You can either download or listen to the half-hour show here (click “play recent episodes”). 

Steve is quite eloquent, as always, covering topics ranging from his own upbringing, his experiments on flies and snails, his role as a popularizer of science, and where the media fails in covering science.

I was interviewed about Steve for this BBC show some months ago, and they’ve used two snippets of my own recollections, especially describing the experiments Steve and I did with others in Death Valley studying how far fruit flies can fly in the desert, and a really beautiful (and largely neglected) experiment we did with Linda Partridge using mutant flies with temperature-sensitive eye colors as a way to determine what climates flies actually experience in the wild (references and links at bottom).

Steve was elected to the Royal Society in April, so at last he can (but won’t) append the vaunted “FRS” to his name.

Relive the moment: the landing of Curiosity

August 6, 2012 • 11:54 am

If you’re one of those wimps or working folk who missed the landing of the rover Curiosity on Mars last night, watch this wonderful 2½-minute video of what happened in the control room (interspersed with reconstructions of the landing).  This has just been posted by the NASA Jet Propulsion Lab at Caltech; thanks to alert reader Michael for the catch:

I have cat!

August 6, 2012 • 8:58 am

Well, only temporarily. Meet Molly, a friend’s cat that I’m tending from last Thursday until tomorrow.  It’s the first cat I’ve had in my crib for years.

At first she was very shy and skittish, staying under the bed or behind the couch for two full days. But the lure of wet cat food, treats, and a heavy dose of petting and scratching has made her friendly. Late last night, during the Mars landing, she hopped onto the bed and watched it with me.

I’ll relinquish her tomorrow, but it was good to have a felid around.  For those of you who wonder why I don’t own one, it’s only because I’m away from home so often and don’t want to leave a cat alone, even with a cat-sitter.

A misguided priest goes after Dawkins and New Atheism, mistakes science for “feeling”

August 6, 2012 • 5:58 am

Open Season on Dawkins is in full swing, and Friday’s Catholic Herald takes a potshot at the quarry in a piece by Father Alexander Lucie-Smith, “The tragedy at the heart of New Atheism.”

On to the tragedy in a second, but Fr. Lucie-Smith’s piece doesn’t begin well:

I remember sitting up and taking notice of something Richard Dawkins once said, which was to this effect: “When aliens arrive here, the first thing they will ask is: ‘Have they discovered the theory of evolution yet?’”

The only problem with this quotation is that I can find no reference to Professor Dawkins actually saying it, or the occasion and context of him saying it. He may not have said it at all. If anyone can give me a reference (the link above, which is hardly satisfactory, is all I can find) then I would be grateful. It would be interesting to unpack the meaning of the words.

For crying out loud, anybody who has read Dawkins is familiar with this quote, which comes from the first chapter of The Selfish Gene. It took me all of two seconds to find the source with Google:

Intelligent life on a planet comes of age when it first works out the reason for its own existence. If superior creatures from space ever visit earth, the first question they will ask, in order to assess the level of our civilization, is: ‘Have they discovered evolution yet?

Nice sentences, eh? Maybe they don’t teach Googling in Priest School.  Anyway, the “tragedy” of New Atheism seems to be the despair and nihilism that comes with realizing that there is no god.  As the good Father writes:

Here is a saying that I find particularly problematic: “The universe we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but blind, pitiless indifference.” [JAC: That quote comes from Dawkins’s River out of Eden.]

First of all, notice the use of the words “precisely” and “observe”. It is surely impossible to observe the universe in its entirety. We observe parts, though we may intuit wholes. But these observations are not going to be precise – not if they are observations of “the universe”. So the use of the words “observe” and “precisely” here strikes me as giving the statement a scientific veracity that it cannot possibly claim, for this statement seems neither falsifiable or verifiable.

What the statement seems to be conveying, rather than a scientific observable truth, is an existential statement of belief about the nature of the universe. While Christians believe that at the heart of the universe there is Love, Professor Dawkins makes an opposing and opposite statement. But if the first statement is unscientific, so surely is the second one as well.

No, Dawkins’s statement is an inference from evidence, an inference that the character of the universe is precisely the opposite of that we’d expect under the notion of a loving and powerful god. Here is some of that evidence:

  1. Innocent people suffer for no apparent reason: children get cancer, thousands are killed by natural disasters.  The problem of evil remains unsolved under the conception of the kind of god I mentioned above. The solution is either that there is a god, and it’s capricious, apathetic or malevolent (and no Christian believes that), or that a god doesn’t exist.
  2. The second alternative—no god—is more parsimonious in view of the complete lack of evidence for a deity.
  3. There could have been evidence for such a deity: miracles, regrowth of amputated limbs, and the efficacy of intercessory prayer.  But there is no such evidence.
  4. Every bit of observational evidence previously adduced by religion for a God: creationism, the existence of morality, the motions of the planets, has given way to science.  Science has never given way to religion.  Thus there’s every expectation that the Last Redoubt of Natural Theology, the “fine-tuning of the universe” and the existence of physical laws, will also be explained by science.  It’s more than just an unsubstantiated assumption, then, that the universe doesn’t care for us: it’s a judgment based on evidence.

Fr. Lucie-Smith apparently doesn’t grasp the evidential basis for rejecting god, for he sees atheism and religious belief as simply both manifestations of “feelings”:

What this might all boil down to are opposing interpretations of experience. Some may feel that they are being protected by a benign Divine Providence and that even when they suffer this suffering can be turned somehow to good. Others may feel that life teaches them that there is no purpose to anything, only blind, pitiless indifference.

How anyone can look at the world and think that a benign and providential God is protecting humans is beyond me. The parsimonious interpretation is “indifference”, i.e., no god.

And then the Big Canard: atheism is equivalent to nihilism:

It seems to me that if Professor Dawkins believes in pitiless indifference as the presiding spirit of the universe, then he is clearly in the camp of an earlier professor, Friedrich Nietzsche. This is a serious matter, because the Nietzschean vision is one that not only contradicts the idea of Divine Providence, but it also makes science of any sort nonsensical, in that it seems to deny intrinsic meaning to physical phenomena, attributing meaning only to human will. In other words, a Nietzschean would say that any theory of meaning is in the head of the person who holds it, not in the phenomena themselves. . .

Is this what Professor Dawkins believes? Is this what modern atheists believe? It does sound pretty close to the quote from Dawkins above. But if he believes this how can he believe in an ordered universe, one that is susceptible to rational and scientific observation?

Since when can one see science as “nonsensical” if there is no intrinsic (i.e., God-given) meaning to physical phenomena? Science works, whether it’s done by an atheist or a believer. Is it nonsensical to give antibiotics to an infected atheist, or for an atheist to develop new drugs? That is a meaningful endeavor regardless of whether there is a god.  Suffering is relieved, regardless of whether the moral view that suffering is bad comes from God or an atheist.  I swear, when I hear an educated priest make statements so palpably false, it makes me see how deeply religion can corrupt rationality.

And while I can’t speak for Professor Dawkins, yes, we atheists believe that humans make their own meaning in life, that science is a valuable thing to do, and that we can be moral without god.  These are all observable facts. And we also believe that an ordered universe can arise from principles of physics, and does not require a caring God.

Curiosity: it’s only just begun

August 6, 2012 • 4:14 am

I know that some of you, as did I, stayed up last night to watch the Mars rover “Curiosity” execute a successful touchdown on the red planet.  It was a highly emotional moment, not just for the engineers, technicians, and other NASA personnel who went wild in the control room when the words “touchdown confirmed” were announced, but also the rest of us. It was a triumph for science and the human spirit, as the readers of my live Curiosity “blog” can attest.  And it was all so improbable.  As Matthew Cobb responded when I asked him if he got up early enough to watch it (he’s in Manchester, England):

No I’m ashamed to say I was asleep. I don’t think I could have stood the tension. I was so sure it was going to fail, given a) Mars’ history and b) the crazy way they decided to land the damn thing. Absolutely astonishing. More amazing and exciting than the whole of the Olympics put together.

There’s a short—too short—account of the landing by Kenneth Chang in today’s New York Times; it includes this:

The landing, involving a seemingly impossible sequence of complex maneuvers, proceeded like clockwork: the capsule containing Curiosity entered the Martian atmosphere, the parachute deployed, the rocket engines fired, the rover was lowered and, finally, the Curiosity was on the ground.

Over the first week, Curiosity is to deploy its main antenna, raise a mast containing cameras, a rock-vaporizing laser and other instruments, and take its first panoramic shot of its surroundings.

NASA will spend the first month checking out Curiosity. The first drive could occur early next month. The rover would not scoop its first sample of Martian soil until mid-September at the earliest, and the first drilling into rock would occur in October or November.

Because Curiosity is powered by electricity generated from the heat of a chunk of plutonium, it could continue operating for years, perhaps decades, in exploring the 96-mile-wide crater where it has landed.

Meanwhile, Irish comedian and science lover Dara O’Briain said this on Twitter:

And this is the photo, taken by C. S. Muncy:


It’s a great morning to be a human.

Oh, and if you’re late to work today (I’m a bit groggy myself), you can haz this from xkcd:

p.s. If you like science that much, read the damn sloth post!

Mars rover on the way: live “blogging”

August 5, 2012 • 10:22 pm

This is the first time I’ve ever woken up to do a post, but I’m watching the Mars lander. At 12:22 AM Central time (US), all is well.

12:26 AM: Guided entry started

12:29: Parachute deployed

12:31: Parachute jettisoned; powered descent beginning.  All still ok.

12:32: TOUCHDOWN!!!! Delirium in the control room—years of effort vindicated!

12:34: Pictures are being broadcast, though I can’t quite make out what is being shown. Ah, now I can; the rover’s wheel is resting on the Martian surface.

Two live pictures from Curiosity. It’s resting on the Martian surface and you can see the horizon as a curvature in the right-hand photo, as well as a wheel of the rover Curiosity (lower right).  I believe the left-hand photo was taken before the dust had settled.

How can anyone have watched this and think that science and scientists are cold and unfeeling? What an emotional moment, to have labored so long to achieve such a success.  And this is just the beginning: now we’ll begin getting data about what things are like on Mars.

This tired but excited boy is going back to bed.  Those still watching, please keep posting as new information or photos come in.

Goodnight!
