Roberto de Mattei

  Roberto de Mattei

Italian scientists probably weren’t surprised when they saw in the bookstores a new work entitled Evolutionism: the Decline of a Hypothesis. Italy does have a fairly substantial Creationist movement, and the statements the book made were pretty close to Creationist doctrine: Dinosaurs didn’t go extinct until 40,000 years ago, what scientists take to be fossil strata are only high-water marks from Noah’s Deluge, etc.

But if they recognized the name given as the book’s author the case became stranger. His name was Roberto de Mattei, also known as the person occupying the second highest office, after only the president, of Italy’s National Research Council, the principal source of funding for scientific research anywhere in the country. Not only that but it began to look as though the Council had even helped to underwrite the cost of publishing the book.

Well, the Italian public is pretty used to scandals, although they usually involve sex or money. Maybe it’s time for a little variety.

Ardipithecus ramidus

Ardipithecus ramidus

 
Until 1994, the oldest fossil of a possible ancestor of ours was a mere three and a quarter million years old,. Then some teams of excavators in Ethiopia’s Afar Depression began turning up pieces from some three dozen individuals, all from the same species of hominid, called Ardipithecus ramidus, and dated at 4,400,000 years Before Present. Of all those fragments by far the greatest number — 125 or so — came from a single female, not more than four feet tall and with a brain not a lot bigger than a chimpanzee’s, named for short Ardi.

Ardi doesn’t look exactly like a chimpanzee, though she’s (probably) furred and with a less jutting jaw than a great ape. If one of them were to turn up next to you at the pool, the most unexpected feature you would see would be the long, dexterous opposable big toe on each foot. This made it easier for Ardi to get around on tree branches, and that made it probable that she lived in a wood, rather than the soggy swamp that some Hollywood designers prefer to show.

Blushing dunce

A few weeks ago, I responded to a comment by a viewer who signs himself TJIC to say, among other things, that there was a species of penguin in Antarctica which is steadily moving its breeding grounds farther and farther south. The reason it does this is to migrate to colder latitudes in order to try to avoid the warming which messes up their oceanic ice.

That much of what I said appears to be true, but then I went on to say that if the penguins went on migrating in that direction they would sooner or later reach a point so far south that the Sun would never rise at all and it would be eternally dark.

That’s ridiculous. There’s no such place. Simple geometry proves that.

I had misunderstood something my source said — I now suspect that it was something about no longer having any ice to worry about because they were now in the middle of the Antarctic continent — and written it down wrong. So now to all of you I bare my throat and say I’m sorry.

 
There’s one other thing in that dashed-off answer that needs a little elucidation. What I said was, “… at one point in history (the scientific) community believed that the Sun went around the Earth and then, not all that much later, reversed their opinion…”

That’s not exactly wrong. It’s incomplete, though. It’s not just that the world’s scientists habitually look at any two theories presented to them, the old and the new, and say, oh, yeah, that new one is more complete, more accurate and more useful than the old one, so from now on I’m with the new.

That does happen, but it’s only part of the process. The other part is that a number of scientists cling to the old theory until they die, evidence be damned. But then they do die, and the generation of new scientists that follow them grow up with that new theory already embedded in their minds.

So it’s true that at one time almost all scientists believed that the Sun orbited around the Earth, and at a later time almost all scientists believed that the Earth orbited around the Sun. But they weren’t the same scientists.

Wonder Stories, April 1933

I don’t know what kind of a writer I would have been if I hadn’t met Dirk Wylie and, through him and with him, the whole world of science-fiction fandom. Much the same, I imagine. I almost certainly would have been some kind of a writer — I’m hardly fit for anything else. And I had been trying to write sf at least a year before I met Dirk, in idle moments in classes in the eighth grade. But it would have taken a lot longer.

I owe a lot to fandom. From Don Wollheim, John Michel, Doc Lowndes — and later from Cyril Kornbluth, Dick Wilson, Isaac Asimov and others — I learned something about what they were learning about writing; we all showed each other our stories, when we weren’t actually collaborating on them. In the fan mags, I acquired the skills necessary to prepare something for public viewing — and the courage to permit it.

What I am not as sure of is whether all the things we learned then were worth learning.

Science fiction was purely a pulp category in those days. Sometimes the emphasis was on gadgetry, sometimes on blood-and-thunder adventure; when it was best, the high spots were vistas of new worlds and new kinds of life. In no case was it on belles-lettres, nor was it a place to look for fresh insights into the human condition. What we learned from each other and from the world around us was the hardware of writing. Narrative hooks. Time-pressure to make a story move. Character tags — not characterization, but oddities, quirks, bits of business to make a person in a story not alive but identifiable. So I learned how to invent ray-guns and how to make a story march, but it was not for a long, long time that I began to try to learn how to use a story to say something that needed saying.

In fact, when I look back at the science-fiction magazines of the twenties and the early thirties, the ones that hooked me on sf, I sometimes wonder just what it was we all found in them to shape our lives around.

I think there were two things. One is that science fiction was a way out of a bad place; the other, that it was a window on a better one.

The world really was in bad trouble. Money trouble. The Great Depression was not just a few million people out of work or a thousand banks gone shaky. It was fear. And it was worldwide. Somehow or other the economic life of the human race had got itself off the tracks. No one was quite sure it would get straight again. No one could be sure that his own life was not going to be disastrously changed, and science fiction offered an escape from all that.

The other thing about the world was that technology had just begun to make itself a part of everyone’s life. Every day there were new miracles. Immense new buildings. Giant airships. Huge ocean liners. Man flew across the Atlantic and circled the South Pole. Cars went faster, tunnels went deeper, the Empire State Building stretched a fifth of a mile into the sky, radio brought you the voice of a singer a continent away.

It was clear that behind all this growth and acceleration something was happening, and that it would not stop happening with huge Zeppelins and giant buildings but would go on and on. What science fiction was about was the going on. The next step, and the step after that. Not just radio, but television. Not just the conquest of the air, but the conquest of space.

Of course, not even science fiction was telling us much about the price tag on progress. It told us about the future of the automobile; it didn’t tell us that sulphur-dioxide pollution would crumble the stone in the buildings that lined the streets. It told us about high-speed aircraft, but not about sonic boom; about atomic energy, but not about fallout; about organ transplants and life prolongation, but not about the dreary agony of overpopulation.

Nobody else was telling us about these things, either. A decade or two later science fiction picked up on the gloom behind the glamour very quickly, and maybe too completely. But in those early days we were as innocent as physicists, popes and presidents. We saw only the promise, not the threat.

And truthfully we weren’t looking for threats. We were looking for beauty and challenge. When we couldn’t find them on Earth, we looked outside for prettier, more satisfying places. Mars. Venus. The made-up planets of invented stars somewhere off in the middle of the galaxy, or in galaxies farther away still.

I think we all believed as an article of faith that there were other intelligent races in the universe than our own, plenty of them. (I still believe it! What puzzles me is why we haven’t seen any of them as visitors. I wish I could swallow the flying-saucer stories — I can’t; the evidence just isn’t good. But the absence of hard facts hasn’t shaken my faith that Osnomians and Fenachrone are out there somewhere.) If polled, I am sure we would have agreed that wherever there’s a planet, there’s life — or used to be, or will be.

Now, alas, we know that the odds are not as good as we had hoped, especially for our own solar system. The local real estate is pretty low quality. Mercury is too hot and has too little air; Venus is too hot and has too much, and poisonous at that. Mars is still a possibility, but not by any means a good one — and what else is there? But in the mid-thirties we didn’t know as much as we do now. The big telescopes hadn’t yet been completed, and of course no spaceship had yet brought a TV camera to Mars or the Moon.

But we believed.

Emperor penguins in Antarctica.

Emperor penguins in Antarctica.

If you’ve seen me lately, you might have noticed a good-looking blonde hanging around. That’s my wife, Dr. Elizabeth Anne Hull, who may soon be famous as the editor of what I think may be close to the best science-fiction anthology ever published, but is already locally well known as a woman who has gone swimming in both Arctic and Antarctic waters. It happened on two trips, several years apart, but I’ll tell you what I learned about the two remotest sections of our world now.
 

Betty Anne and me.

Betty Anne and me.

The Antarctic is said to be very cold, but when we were next to the Palmer Station on the Antarctic peninsula the air temperature was 37 degrees F. When we left Chicago, the temperature at O’Hare had been –4.

Antarctic ice comes in several pretty colors, It is blue or green if it has been at the bottom of some heavy layers of other ice and the air has been squeezed out of it, rarely reddish or yellowish if it has picked up a load of algae or something and — everybody’s favorite — the rest of the time most of it is the whitest white you ever saw.

The principal visible inhabitants of Antarctica are penguins. There are more than a dozen brands of penguins, but which brand any given penguin belongs to is of real concern only to another penguin. I can tell the difference, but only if they’re fairly close and I have the guidebook in my hand.

A pretty sight is to see several Buick- to bungalow-sized ice floes sailing by, each one with a penguin catching a free ride by sitting on its top.

Penguins live on land but have to return to the ocean if they want to catch anything to eat. This makes quite a problem for them because on the other side of one of those holes in the ice that they use to let them get into the water may well be one or more hungry seals, who are swimming around down there, waiting in the hope of catching a penguin for the same purpose. That is why you see the number of penguins parked next to a hole growing until, at last, one of them dives in and the rest follow pretty much all at once. If there is a single famished seal waiting there he’ll catch one of the penguins, all right, but the rest are home free.

Penguins don’t exactly swim. They sort of fly through the water and are very good at it.

Ice floes come in all shapes and sizes, some like castles with towers and minarets, some like craggy mountain ranges, some like huge, flat, square-cut pizza boxes, some like nothing you’ve ever seen before.

Most of a berg or floe is under water with a lot of mass and jagged edges. Consequently every once in a great while one of them holes a ship, and then there’s big trouble. One small cruise ship did go down a few years ago, with I believe two people trapped inside.
 

While on the other end of the planet —

 
The Arctic Ocean contains no continent (though it is bounded by several) and very few islands (although one or two new ones are being discovered as the ice melts away).

When we sailed north toward the Pole, we hit lucky on the weather. It was fair and not very windy, thus giving us only gentle waves. As we approached the Arctic ice cap there was at first only a vague blur on the horizon. Then abruptly it transmuted itself to what looked a wide bay that we were entering. The closer we got, the more it began to look like — wow! — a tropical island that we were approaching, with a narrow beach of white sand, lacking only some palm trees and a central mountain to resemble Bora Bora or Moorea.

Actually, that whole scene was composed of nothing but size-sorted bits of floating ice. We were almost on top of it before I could see that the “beach” part was made up of a gazillion tiny ice bits, more or less marble-sized, next to a band composed of larger strawberry-to-baseball sized pieces, then one band after another, each band’s pieces getting bigger and bigger as you headed Poleward. Each separate piece of ice was jigging independently up and down in the gentle waves but they all kept to their spots within the group. (I developed a theory that there was a feeble northward current around there, perhaps a straggling fragment of the dissipating Gulf Stream, pushing on the surface waters to line the ice fragments up so neatly, but never found an oceanographer to tell me how all wet I probably was.)

Then the captain took us right into the ice, all the thousands of tons of our cruise ship, until we were more than a quarter mile from open water and getting a bit close to some biggish ice floes. The captain stopped the ship so we could all take pictures. (And, gee, I wish I had.) And then he carefully backed us out of the ice, staying within the liquid-water lane we had opened on the way in.

 
There aren’t any penguins in the Arctic. What they do have there is the local knock-off of the same general design, the auk, only they don’t have many of them anymore because 19th-century sailors found them quite tasty. We didn’t see any, anyway. Other Arctic creatures we didn’t see include polar bears, Arctic foxes and various aquatic and semi-aquatic forms.

We did see some whales.

 
Oh, and listen, those waters in the Arctic and Antarctic that I said Betty Anne had gone swimming in. Did I mention that they were the swimming pools located on the upper decks of our cruise liners?

 

The next total solar eclipse is predicted for 11 July 2010.

The viewable path of the next total solar eclipse, predicted for 11 July 2010.

Remember Omni? It was a wonderful, slick-paper magazine published and edited by Bob Guccione and his gorgeous wife, Kathy Keeton, and I just this minute realized that one of the reasons I liked it so much was that its basic editorial policy was pretty much identical with that of this blog: Its primary interests were science fiction and science, with excursions into anything else that attracted the attention of its editor — in Omni’s case Guccione, in this blog’s case me. We knew that we had interests in common, too, and that’s why I did a lot of writing for Bob’s magazine throughout its all-too-short history.

Pretty much the whole editorial staff of Omni suffered from the same streaks of curiosity as Bob and Kathy and I did, which included not only the policy-makers but the ones that made it happen day by day — that is, Ben Bova, Bob Sheckley and maybe one or two others. And when, in the spring of 1991, we all became aware that one of those splendid sky shows that are called total eclipses of the sun was going to happen later that year it seemed to all of us that someone (preferably me) should cover the event for the magazine.

At the same time, I’ve been looking over some pieces I wrote on various subjects for various periodicals long ago, and wondering how many of you guys would like to see some of them reprinted here. So let’s find out. And to do that, here’s the eclipse of ’91 report, just as Omni published it nearly twenty years ago.

 
7:27 a.m., July 7, 1991. We’re ninety-six hours from the eclipse, but some of the dedicated eclipse fans are already out on the starboard railings of the S.S. Independence, squinting anxiously at the sun. It’s good and bright, right this minute. That’s pretty much the way you’d expect the sun to be here in these sunny Hawaiian waters, and the good news is that if the moon were going to slide in front of it today instead of four days from now you’d surely say that it was being eclipsed, all right. The bad news is that you wouldn’t be able to make out some of the fainter outer corona because there’s a thin, high fan of cirrus that starts at the horizon and spreads out over the eastern sky. It won’t keep you from getting a sunburn, but it’s just enough to fuzz out the fainter patches of coronal light. Maybe our luck will be better on July 11.

Maybe it won’t, too. Pacific skies are cloudy. I’ve flown over this ocean twice in the last few weeks, fourteen and a half hours from San Francisco to Hong Kong, and there was never a minute when I could look out my window and see no clouds in the sky at all. This morning there are fluffy little clumps of cumulus all over the eastern horizon. Twenty minutes later, while we’re eating our breakfast papaya and omelets on the fantail, a couple of clumps slide right over the sun, and that’s the kind of thing that can really spoil an eclipse for you.

Of course, on the Independence we’ll be a moving target. We should be able to dodge a few cumulus shadows. We’d better do it, too. There are 800 passengers who have booked passage on the Independence for the sole and simple reason that they want to see the sun go out. If they don’t see it with their own eyes some of them are going to be thirsting for blood.

Alan Turing

Alan Turing
 

The close of Pride Month seems an apt time to talk about Alan Turing, inventor of the famed Turing Test for identifying independent intelligence in computers, who worked for the British code breakers in World War II, and was one of the leading figures who successfully cracked the secret German messages, a feat which played a considerable part in the victory over Hitler.

Turing was, however, a homosexual. After the war, he was arrested and convicted of “gross indecency.” He was promised to be spared prison, provided he agreed to allow himself to be injected with estrogens to “cure” his condition. Turing made the deal, but two years later, he killed himself by eating a poisoned apple.

After a group of scientists launched a movement to expunge his conviction and honor his name in his home country of England last year, then-Prime Minister Gordon Brown issued a posthumous apology to Turing on behalf of the British government. Turing was already honored in much of the rest of the world; for example, in America, the Association for Computing Machinery has presented the Turing Award, the field’s top award, since 1966.
