Don’t Know Much About Gravity

…or at least as much as we think we do. Does the gravity model need to be adjusted?

In the one probe the researchers did not confirm a noticeable anomaly with, MESSENGER, the spacecraft approached the Earth at about latitude 31 degrees north and receded from the Earth at about latitude 32 degrees south. “This near-perfect symmetry about the equator seemed to result in a very small velocity change, in contrast to the five other flybys,” Anderson explained — so small no anomaly could be confirmed.

The five other flybys involved flights whose incoming and outgoing trajectories were asymmetrical with each other in terms of their orientation with Earth’s equator.

For instance, the NEAR mission approached Earth at about latitude 20 south and receded from the planet at about latitude 72 south. The spacecraft then seemed to fly 13 millimeters per second faster than expected. While this is just one-millionth of that probe’s total velocity, the precision of the velocity measurements was 0.1 millimeters per second, carried out as they were using radio waves bounced off the craft. This suggests the anomaly seen is real — and one needing an explanation.

Well, gravity just like evolution, is (in the words of anti-evolutionists) only a theory. It’s not reality–it’s simply an attempt to model it. And for most purposes, it does a pretty good job. But one of the reasons to do space, I think, is that it gives us new laboratories to make new discoveries about basic physics, the potential of which is unforeseeable.

Idiot Alert

Over at Reason, the sad tale of a free-loader wannabe:

The group was now “out of food, hadn’t slept in days and were really cold,” and decided, in a grubby version of Dunkirk, to abandon the mission and head back to England. Boyles is disappointed-but not deterred. He is, the BBC reports, planning “to walk around the coast of Britain instead, learning French as he goes, so he can try again next year.” At which point the cycle begins anew, when, upon reaching Baden-Baden, the poor lad will realize that he should have also studied German.

As Wilde said in another context, one would have to have a heart of stone to read this and not laugh out loud.

Was Burke A Fascist?

Some thoughts from Jonah.

And I thought this bit, while not directly pertinent to the point, did seem pertinent to some recent discussion here.

The reaction from so many liberals to William F. Buckley’s death is a good case in point. How many of them insist that even though Buckley recanted his earlier views on race that these views are all important and eternal when it comes to assessing the man? But the fact that the founding fathers of Progressivism and modern liberalism were chock-a-block with imperialists, racists, eugenicists, fascist-sympathizers and crypto-fascists is not only completely irrelevant but tediously old news? Am I alone in seeing a disconnect here?

No. No, you’re not.

RIP WFB

While I’m not a conservative, and never have been, I came to appreciate William F. Buckley much more as I grew older and started reading National Review (though not consistently–I’ve never had a subscription) back in the Reagan years. An intellectual giant has passed.

The Corner is (not surprisingly) all WFB all the time right now.

[Update at 2:30 PM]

A tribute from Mario Cuomo:

I was privileged to know William Buckley for more than 20 years and was in fact his opponent in his last public debate.

He may not have been unique. But I have never encountered his match. He was a brilliant, gentle, charming philosopher, seer and advocate.

William Buckley died … but his complicated brilliance in thought and script will survive him for as long as words are read. And words are heard.

[Early evening update]

Bob Poole weighs in, with a libertarian perspective:

By creating National Review in 1955 as a serious, intellectually respectable conservative voice (challenging the New Deal consensus among thinking people), Buckley created space for the development of our movement. He kicked out the racists and conspiracy-mongers from conservatism and embraced Chicago and Austrian economists, introducing a new generation to Hayek, Mises, and Friedman. And thanks to the efforts of NR’s Frank Meyer to promote a “fusion” between economic (free-market) conservatives and social conservatives, Buckley and National Review fostered the growth of a large enough conservative movement to nominate Goldwater for president and ultimately to elect Ronald Reagan.

In many ways, this is a loss for the conservative (and libertarian) movements even greater than that of Reagan. But due to his influence, which is immeasurable, he leaves behind many to pick up and carry the torch for freedom forward.

[Evening update]

Ed Kilgore has further thoughts:

Buckley once said he offered his frequent polemical enemy Arthur Schlesinger, Jr., a “plenary indulgence” for his errors after Schlesinger leaned over to him during a discussion of the despoilation of forests and whispered: “Better redwoods than deadwoods.” And that’s certainly how a lot of us on the Left feel about the legacy of William F. Buckley, Jr. (see progressive historian Rick Perlstein’s tribute to WFB’s decency and generosity at the Campaign for America’s Future site). He made us laugh, and made us think, and above all, taught us the value of the English language as a deft and infinitely expressive instrument of persuasion. I’ll miss him, and so should you.

It’s a shame that I have to suffer pea-brained feces-flingers in my comments section on the occasion of his passing. That person will clearly never be able to use the English language as an expressive instrument of persuasion, infinitely or otherwise. It’s sad that he’s unable to realize how unpersuasive, and deserving of the contempt of all, that he is. It’s equally sad that he has no sense whatever of shame, no matter how deserving.

[Update early Thursday morning]

The Washington Post says that Buckley will be missed. Well, not by certain scumbags in my comments section, of course. But who cares about them…?

[Update early morning on February 28th]

Here’s a huge compendium of encomia from all points on the political spectrum. Sadly, the only unbonum words that I’ve seen have been expressed in my own comments section. But then, I don’t deliberately go to the wacko leftists web sites.

Terminators, Coming Up

Alan Boyle has an interesting post on the ethics of killer robots.

“Asimov contributed greatly in the sense that he put up a straw man to get the debate going on robotics,” Arkin said. “But it’s not a basis for morality. He created [the Three Laws] deliberately with gaps so you could have some interesting stories.”

Even without the Three Laws, there’s plenty in today’s debate over battlefield robotics to keep novelists and philosophers busy: Is it immoral to wage robotic war on humans? How many civilian casualties are acceptable when a robot is doing the fighting? If a killer robot goes haywire, who (or what) goes before the war-crimes tribunal?

Mystery “Solved”

Scientists now have a plausible, and likely theory for what created the Burgess Shale:

By looking over hundreds of micro-thin slices of rock taken from the famous shales, the researchers have reconstructed the series of catastrophic underwater landslides of “mud-rich slurry” that killed tens of thousands of marine animals representing hundreds of species, then sealed them instantly – and enduringly – in a deep-sea tomb.

The mass death was “not a nice way to go, perhaps, but a swift one – and one that guaranteed immortality (of a sort) for these strange creatures,” said University of Leicester geochemist Sarah Gabbott, lead author of a study published in the U.K.-based Journal of the Geological Society.

I use the scare quote because that’s the word used in the headline. This kind of language, I think, is (at least partly) what bothers people who continue to rebel against evolution, and science. It is a certainty of language (like “fact,” rather than “theory”) that they consider hubristic, and arrogant. After all, when Sherlock Holmes “solved” a case, it generally was the last word, case closed.

In this case, what the word means is that scientists have come up with a plausible explanation for an event for which they’d been struggling to come up with one for a long time, and it is sufficiently plausible that there are few scientists who argue against it, thus presenting a consensus. Does it mean that they have “proven” that this is what happened? No. As I’ve written many times, science is not about proving things–scientists leave that to the mathematicians. What scientists do (ideally) is to posit theories that are both reasonable and disprovable, yet remain undisproved.

There may be some other explanation for what happened up in what is now Yoho National Park that corresponds better to what really happened, but until someone comes up with one that makes more sense, or comes up with some inconvenient indisputable fact that knocks this one down, it (like evolution itself) is what most scientists, particularly the ones who study such things for a living, will believe.

And of course, I won’t even get started on how upset some anti-science (and yes, that’s what they are, even if they don’t recognize it) types will get over the statement that one of the ancestors of humans is in that shale.

[Update a few minutes later]

Oh, the main point about which I put up this post. This is an excellent illustration of how rare are the circumstances in which we find the keys to our biological past. Those that demand that we cannot know the history of life until every creature has died on the body of its parents, perfectly preserved, are being unreasonable. To paraphrase Don Rumsfeld, we do science with the (rare) evidence that we have, not the evidence we’d like to have. There will always be many huge holes in the fabric of the evidence, barring the development of a time machine to the past. We simply do the best we can with what we have, and put together theories that best conform to it. To say that God (or whoever) did it isn’t science–it’s just a cop out. And that is true completely independently from the existence (or not) of God (or whoever).
