Genesis crashes

The Genesis spacecraft, a NASA mission designed to collect particles from the solar wind and bring them back to Earth for study, has crashed into the Utah desert. Apparently there were at least two problems, likely to be related: the craft was not correctly rotating so as to maintain its attitude during descent, and the parachutes that were supposed to break its fall never opened. The original plan was for a daring rescue in which stunt pilots would snag the vehicle as it fell to Earth. It’s not clear at the moment whether the samples will be able to be recovered; scientists are examining the craft carefully, as the parachutes may still be explosively deployed.

How would Jesus vote?

From Crooked Timber, the local political news is fraught with religious significance: Alan Keyes says that Jesus wouldn’t vote for Barack Obama. (Presumably, He would vote for Alan Keyes, although Keyes is too humble to draw the obvious conclusion.)

For we non-believers, these esoteric theological discussions are all very confusing. I’ve gotten the wrong impression countless times by simply reading the Bible without an expert commentator at my elbow to help me along. Consider for example the famous passage in Matthew 19:24:

And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.

(The story is repeated in the other synoptic gospels, Mark and Luke.) Now, the meaning here seems pretty straightforward to the uneducated reader — rich people are going to have a really hard time getting into Heaven. An impossible time, actually; as Jesus surely knows, camels don’t fit through the eyes of needles. (Some weasels try to claim that the “eye” was really a gate outside Jerusalem, or the “camel” was really “rope,” but these ideas have been rightfully smacked down.) But that’s only because I’m a naive reader of the scriptures. At least I am quicker on the uptake than Jesus’ disciples, who dutifully play the straight man:

When his disciples heard it, they were exceedingly amazed, saying, Who then can be saved?

Here I would have expected Jesus to slap the disciples, aggravated at their cluelessness. If rich people won’t enter the kingdom of God, it seems pretty obvious that Heaven would be populated by (formerly) poor people. But that’s why I’m a physicist rather than the Messiah. Jesus explains:

But Jesus beheld them, and said unto them, With men this is impossible; but with God all things are possible.

So the point is not that rich people won’t enter Heaven; it that’s they can only enter with the help of God (just like everybody else)! All those parts of the Bible where Jesus appears to be saying disdainful things about wealth are really just a smokescreen — what’s important is not how much money you have, but how deeply you believe in Him. Otherwise how could our President stand a chance?

So I’m not going to offer an opinion about who Jesus would vote for. For all I know, He may think that the good citizens of Illinois should walk around carrying concealed machine guns. Sure would make the morning commute on the El more exciting!

Disagreement is Treason

Brian Leiter, prompted by Jessica Wilson, who was prompted by an essay at That Good Night, wonders whether recent events in the U.S. can usefully be thought of as proto-fascist. Specifically, are there interesting parallels between the U.S. today and Germany in the 1930’s? Let me go out on a limb here and provide a straightforward answer: yes and no.

“No”, in that I think there is essentially zero danger of the U.S. transforming into a fascist dictatorship any time in the foreseeable future. For one thing, as wrong-headed as they may be, nobody in the Bush administration actually wants to overthrow democracy. (Okay, maybe Ashcroft, but he’s only one guy.) It’s true that they want to paint everything in black and white and portray any kind of disagreement as treasonous, but that’s not enough to qualify as fascism. More importantly, democratic ideals are simply too deeply ingrained in U.S. society to allow any realistic chance of transforming into a dictatorship.

So, one’s first response is to think that even asking the question is somewhat alarmist, if not hysterical. But we should keep in mind that historical fascism was quite popular at certain times in certain places, and it’s perfectly reasonable to ask whether the impulses that led to some of the dramatic movements of the past are at work in our present situation. In a more recent post Leiter points to this short essay by Umberto Eco, discussing the universal characteristics of fascist societies. I have to say, some of the features Eco identifies are uncomfortably familiar. For a while now, like many other liberals, I’ve been trying to understand how any reasonable person could possibly support the current administration, which makes wrong choices nearly every time by any sensible criteria. Of course there are many answers to this question, but I think one huge factor (reflected quite explicitly in the campaign rhetoric) is the valorization of certainty (or “decisiveness”) over nuance or complexity (“flip-flopping”). There seems to be a strong feeling among Bush supporters that taking a definitive stand is more important that what that stand is. I don’t mean to be condescending, but this point of view is so alien to me that I can’t really do it justice. To these people, the war in Iraq was justified because Saddam was our enemy, regardless of the absence of weapons of mass destruction or any connection between Iraq and 9/11. It is taken as a sign of strength, rather than a bumbling approach to diplomacy, that our nominal allies are predominantly aligned against us across a range of foreign-policy questions. It is to these people that Dick Cheney’s smirks at Kerry’s “sensitive war on terror” are directed — in this view, the last thing you want to do in a war on terror is to understand the minds of the enemy.

To get back on track: Eco makes a strong case that a main theme of fascism is to establish a comfortable zone of certainty in which dissent, and even ambiguity, are considered traitorous. It is a feeling fed by resentment, both of ruling elites generally and of intellectuals in particular. You can see how such a stance might be compelling — it feels good to be a virtuous Everyman, defending one’s way of life against enemies at home and abroad. In a complicated world, there is comfort to be found in leaning on simple, strong, patriotic truths, whether decorating the town with American flags or lashing out with the armed forces. When Ann Coulter labels liberals as treasonous, or Zell Miller gives soldiers credit for freedom of speech, or Rick Santorum demonizes gays and atheists, they are appealing to exactly this feeling of unreflective anger.

After reading Eco’s essay, I am no more convinced than before that we are in any danger of becoming a fascist state, but I do think that the underlying principles of proto-fascism have something important in common with the motivating philosophies of the Bush administration. It explains much of what is otherwise confusing about Bush’s policies, especially to more libertarian-leaning conservatives. From the crusade against gay marriages, to the dramatic undermining of independent scientific advisory councils in policy making, to the cheerful disregard of judicial due process, to the sanguine acceptance of budget deficits and protectionist trade policies, we see a consistent appeal to a resentful and frustrated middle class.

There is a danger in throwing around scare words like “fascism”, that we will denigrate the level of political discourse even further. But we shouldn’t forget that historical fascism really was attractive to a large number of people, and for strong reasons; it’s not impermissible (yet) to think soberly about what those reasons were, and what relationship they have to political currents that still run strongly today.

Moment of silence

A nice gesture from the director of Fermilab.

September 7, 2004

To: The Fermilab Community

From: Michael Witherell, Director

Subject: Three Minutes of Silence at Noon Today

As children returned to classrooms around the US last week, a terrible tragedy unfolded at a school in Beslan, Russia. Violence claims lives every day, but when the victims are children we are even more deeply affected.

At Fermilab, it is both our privilege and our responsibility to carry forward the tradition of a field long known for its leadership in international collaboration. This tradition allows us to know one another as people as well as representatives of other nations. Fermilab has many close ties with Russia. Russian scientists and engineers are leading members of our staff, and many from Russian institutions participate in DZero, CDF, MINOS, BTeV, and CMS. To all of our Russian colleagues, we express our sorrow.

I ask you to observe three minutes of silence today, throughout the laboratory, beginning at 12:00 noon, in sympathy and solidarity with our Russian colleagues here at Fermilab and around the world.

Advice

As a Labor Day special here at Preposterous, we offer some advice for anyone out there who might be thinking of becoming a professional academic physicist. Fortunately, since the spirit of Labor Day is that you’re not supposed to do any work, I can just link to other people who have already written various pieces of good advice.

  • Starting at the top, Nobel Laureate Gerard ‘t Hooft offers a crash course (that would only take a few years) on how to become a good theoretical physicist. ‘t Hooft, for those who don’t know, is one of the startlingly smart physicists of the modern era. I interacted with him a little when we were thinking about time travel in three dimensions. He would make some sort of claim that we didn’t believe, and give a thoroughly unconvincing explanation for why it was true, and almost always turn out to be right in the end. My hypothesis at the time was that he was actually a marginally-talented time-traveling physicist from the future, who knew all sorts of true things but had trouble justifying them. But he recommends my general relativity lecture notes, so I have to compliment his taste. (Although he insists on misspelling my name, which you would think he’d be more careful about, given his own struggles to get people to punctuate his name correctly.) His web page is also very charming, well worth checking out.
  • Amanda Peet, a string theorist at the University of Toronto (not the actress), has two very useful advice pages: one for high school students deciding what to major in, and another for undergraduates contemplating graduate school. Both are aimed at students who are particularly interested in string theory, but much of the advice is pretty universal. (Amanda is also using my book for a course she’s teaching this year, so she also gets points for taste. You can see my criteria for deciding whom to link to — it’s all about me me me, baby.)
  • John Baez is a mathematical physicist working on quantum gravity, who has become well-known for his wonderful expository articles on all sorts of physics topics. He has a page of advice for young scientists that covers both philosophical issues and very practical matters.
  • Just because you’ve arrived at graduate school (or become a professor, for that matter) doesn’t mean you have it all figured out. Michael Nielsen has written a thoughtful series of blog posts on the principles of effective research, something we’re all constantly trying to figure out but rarely making explicit. (At the moment the site appears to be down, but I hope I have the url right.)
  • As a more specialized skill, my colleague Bob Geroch has written some suggestions on giving talks. Very few people will successfully implement his advice, but if more people at least tried the quality of talks in the field would be immeasurably higher.

These are the pieces of worthy advice that I know about; let me know if there are any good ones I’ve missed. I should say that I only point at all these well-intentioned articles with some trepidation, as reading them all at once could give someone the idea that become a physicist is an incredibly exhausting grind. The impression by no means inaccurate; but the rewards are more than commensurate!

Sunday song lyric

With apologies to Juan Non-Volokh, it’s time for another Sunday song lyric. This time from progressive-rock supergroup Emerson, Lake & Palmer, with bonus theological commentary!

The Only Way (Hymn)

Music by Emerson; Lyrics by Lake

People are stirred

Moved by the Word

Kneel at the shrine

Deceived by the wine

How was the Earth conceived?

Infinite space

Is there such a place?

You must believe in the human race

Can you believe

God makes you breathe

Why did he lose

Six million Jews?

Touched by the wings

Fear’s angel brings

Sad winter storm

Grey autumn dawn

Who looks on life itself

Who lights your way?

Only you can say

How can you just obey?

Don’t need the word

Now that you’ve heard

Don’t be afraid

Man is man-made

And when the hour comes

Don’t turn away

Face the light of day

And do it your way

It’s the only way

Okay, not the most sophisticated statement of the problem of evil (and Lake is trying to sing way outside his range). But when I was younger, hearing this song was what made me realize it might actually be okay to not believe in God.

Fred Whipple

I’m late learning this, but Fred Whipple passed away on August 30th at the age of 97. He was best-known for his work on comets, and played an important role in U.S. astronomy as director of the Smithsonian Astrophysical Observatory (now merged with the Harvard College Observatory to form the Harvard-Smithsonian Center for Astrophysics). I met him a couple of times as a graduate student in the Harvard Astronomy Department; he was a warm and friendly spirit as well as a major figure in astrophysics.

Update: My Ph.D. advisor, George Field, was close friends with Whipple. George mentions with pride how the speakers at the funeral stressed Whipple’s atheism.

Probability of discovery

I’m always on the lookout for ways to make money off of my esoteric physics knowledge. Here’s one: you can bet on the chance that a big physics experiment will discover something by a certain date. Inspired by an article in New Scientist on large physics experiments, Ladbrokes betting agency is placing odds on various possibilities, and taking cash bets up until Sept. 6th. The four bets up there now are: LIGO discovering gravitational waves by 2010 at 2-1; understanding the origin of cosmic rays (presumably they mean ultra-high-energy cosmic rays) by 2010 also at 2-1; discovery of the Higgs boson by the ATLAS experiment at CERN’s Large Hadron Collider by 2010 at 3-1; and completion of a working fusion power station by 2010 at 40-1. Personally I would happily wager 100 pounds to win 300 on the Higgs being discovered, although I’m not sure what happens if the CMS experiment finds it rather than ATLAS. A fusion power plant is very unlikely. I don’t know what counts as “understanding” cosmic rays, so I’d be a little leery of that one. LIGO finding gravitational waves by 2010 is a trickier one — everybody things gravitational waves are out there, so the bet depends more on the technological progress (and funding) of the observatory, which is hard to predict.

Blogs are the best thing ever

As someone with his finger firmly on the erratic pulse of the American body politic, I might at some point in the past have thought of it as my patriotic duty to watch at least a tiny portion of the Republican convention. But in these enlightened and blogospherical times, ordinary folks are saved from the need to torture themselves by the generous sacrifice of intrepid souls with a modem and a sense of humor; between Michael Bérubé and Fafblog!, it’s better than being there.

Extraterrestrials?

Since this seems to be Provocative Day here at Preposterous, I might as well throw this one out there: the Search for Extraterrestrial Intelligence (SETI) project has found a signal they can’t explain, possibly originating from an extraterrestrial civilization. This is something I’m truly not an expert on, so I’ll just point you to some commentary from Simon DeDeo, who brought this to my attention. (Original data here.) The basic idea is that they’ve found a signal at 1420 megahertz (a very noisy part of the electromagnetic spectrum) that has appeared a few times, starting at a fixed frequency and slowly drifting (as if Doppler-shifted from a moving source). Certainly the most likely explanation is some perfectly mundane, although interesting, source of emission in atomic hydrogen. I would put the chance that we’ve actually found some intelligent life to be about one in a million. But that’s a chance worth exploring.

Interestingly, the signal was first identified via the SETI@Home project, running as a screensaver on countless home computers. I have it on mine. We physicists are introducing Einstein@Home, a way you can help search for signals of gravitational waves from LIGO data, but if we’ve found aliens that will never catch on.

Now, what I want to know is, do these aliens feel emotions?

Update: Ooops! Almost before I finished typing, Simon points me to this disclaimer. Now I know how Matt Drudge must feel all the time.
