Philosophia Naturalis

A new physics-oriented blog carnival, Philosophia Naturalis, has just appeared at Science and Reason. Here’s some background explanation. Looks like a great selection of articles.

To celebrate the birth of this new project, I’ll mention this quote from Al Franken, who is contemplating a Senate run in 2008:

There’s all kinds of things that need to be done. Respecting science again. I would like to do a law where no political appointee can change the language of a scientific report without getting the scientists who made the report to sign off on the language change. That’s a law I’d propose on the first day, I think.

Franken brought this up unprompted during an interview with Lindsay Beyerstein. It shows an admirably pro-natural-philosophy viewpoint.

In contrast, we have George W. Bush, who sees his foreign policy as part of a new religious rebirth:

“A lot of people in America see this as a confrontation between good and evil, including me,” Bush said during a 1 1/2 -hour Oval Office conversation on cultural changes and a battle with terrorists that he sees lasting decades. “There was a stark change between the culture of the ’50s and the ’60s — boom — and I think there’s change happening here,” he added. “It seems to me that there’s a Third Awakening.”

The First Great Awakening refers to a wave of Christian fervor in the American colonies from about 1730 to 1760, while the Second Great Awakening is generally believed to have occurred from 1800 to 1830.

Sadly, the one who views his actions through the lens of a titanic supernatural struggle is the President of the United States, while the one who faces up to the real world is a comedian. Draw your own conclusions about the decline of Western civilization.

Birthdays are a good time to reflect on one’s place in the universe. Via Data Mining, here is a map of the blogosphere, on which we have helpfully circled Cosmic Variance.
Blogosphere Map
The original map is interactive, so you can click on each circle to visit the corresponding blog. We are in a good neighborhood, close to such elite properties as Majikthise, Bitch Ph.D., Lance Mannion, Shakespeare’s Sister, Eschaton, The Huffington Post, and Talking Points Memo. At the top you see a big black dot (Engadget) and an even bigger looming orange dot (Boing Boing); the thicket at the right is filled with blogs I know nothing about, which tells you something, although I don’t know what.

Thanks for visiting, everyone! I wonder what this will look like ten years down the road.

Pandering Frivolity

The baleful eye of the establishment media has once again turned our way, and judged us to be sordid muckrakers. Declan Butler at Nature has written about the largest science blogs, and we were happy to find CV in the top five, along with Pharyngula, The Panda’s Thumb, Real Climate, and The Scientific Activist. (Plenty of room to complain about methodologies, but whatever — suffice it to say that prize money was distributed quite equally.) The Technology Chronicles, however, has poked a stick at these would-be science blogs, and found that they succeed not by “politely debating the fine points of string theory” (ahem), but rather by “channel[ing] the static and political undercurrents in their fields.”

Nonsense! We have succeeded by writing about martinis and the World Cup. To cement our reputations as light-hearted bons vivants, today’s post is about poker.

In particular, a quiz. For those of you not addicted to Bravo’s Celebrity Poker Showdown, the game that has swept the public’s consciousness is Texas Hold’Em. It’s just a particular variety of poker, in which each player gets two hole cards that only they see, and then five cards are dealt face-up in the middle of the table. The winner is the one who can construct the best five-card hand out of seven — their hole cards and the five on the board. Complications arise from the baroque betting structure (two players to the dealer’s left are forced to bet on the first round, which is after the two hole cards are dealt; further betting rounds after the first three board cards are dealt, another after the fourth, and a final one after the fifth), but basically it’s just that simple.

So, consider the following three possible pairs of hole cards:

  • Jack-10 suited (e.g., a Jack of diamonds and a 10 of diamonds)
  • Ace-7 unsuited (e.g., an Ace of spades and a 7 of clubs)
  • Pair of sixes

The quiz is extremely simple, and should be easy for experts: assuming you don’t know what anyone else has, or yet what the board cards will be, which possibility is most likely to win at the end of the hand? And (a subtly different question) which is the best Hold’Em hand? Please show your work; answers will be revealed tomorrow. Winners will receive a free lifetime subscription to Cosmic Variance, one of the most popular science blogs on all the internets.

Help Public Schools, Protect the Honor of Physics

In the noble tradition of using the power of blogs for good, Janet at Adventures in Ethics and Science has organized an effort at ScienceBlogs to raise money for school teachers who want to get their students excited about science. It’s an unimpeachably good cause, no matter where your political sympathies might lie.

Donors Choose So all the ScienceBloggers are kicking in, with only one problem: they are dominated over there by the squishy sciences, leaving physicists in the dust. So we here at Cosmic Variance, in the spirit of disciplinary solidarity, are suggesting that you visit Chad at Uncertain Principles and drop a few dollars onto his donor list. Let’s see if we can’t teach those life-science types a thing or two about altruistic selection. (There are even contests you can win, so any Objectivists motivated entirely by enlightened self-interest are also encouraged to participate.)

Welcome to the Blogosphere

No, not you; you’re already here in the blogosphere. I’m talking about all those physicists out there to whom “blog” sounds like something you feel compelled to do after doing too many Smirnoff shots the previous evening, rather than the place you go for the most erudite and challenging large-scale conversation in human history.

Blogs are a tool of immense power that people haven’t quite figured out how to use quite yet. Physicists, in particular, have been slow to take advantage of this new medium (with a few brave and laudable exceptions, of course). A peek at our blogroll or a visit to Mixed States would give the impression that there is a lot of physics blogging out there, which is certainly true; but “a lot” needs to be compared with the dominance of more traditional forms of communication (papers, talks, conferences, books, journalism), or the much more eager adoption of blogging by the tech community, or even within academia by law professors and social scientists. Professional physics, let’s face it, is a step removed from the concerns of most people on the street, and rather than work to overcome this barrier by making the excitement of their research more accessible, most working physicists are happy to remain relatively isolated within their research communities. Besides, blogging takes time, and who has that?

It was with Luddite preconceptions such as these in mind that I recently wrote a Back Page article for APS News, the house newsletter of the American Physical Society, on the joys of blogging. I was invited by Jennifer Ouellette, who is the assistant editor of APS News when not blogging up a storm in her own right at Cocktail Party Physics (and who was also at YearlyKos). Most people don’t know anything about blogs, and if they haven’t actually started reading them it’s quite difficult to give an accurate description. So I tried right from the start to defuse some of the most pernicious stereotypes.

I know what you’re thinking. You’ve heard of these things called “blogs,” some sort of web journals feverishly updated by pajama-wearing authors convinced that the world is in desperate need of access to their innermost thoughts. Who has time to pay attention to such frivolities? Fortunately, as serious physicists we need not worry that our lives will be affected by this latest example of overhyped cyber-enthusiasm. Just like our lives were unaffected by the advent of email and electronic preprints.

When I’m asked what blogs are all about, I start by saying they are like magazines—collections of serially presented articles (called “posts” in the blog context), published on the internet instead of in bound paper editions. Blogs are a technology for conveying information. Like magazines, blogs can be about anything. The purposes to which we choose to put this technology are nearly infinitely flexible.

I go on to talk about some of these purposes, in particular the distinct (but complementary) ideas of using blogs for technical conversations between researchers, vs. spreading news and musings about science to a wider audience, vs. random discussions about whatever you want because hey, it’s your blog.

One of the things that people really don’t quite get, until they’ve taken the plunge themselves, is how easy it is to start up a new blog. At the lowest level of effort, anyone can start a brand-new blog for free within minutes by popping over to Blogger and just signing up. Give yourself an hour or two to choose a name and a color scheme, and you’re off. If you spend another hour setting up a blogroll and remember to occasionally link to other bloggers, they will notice you and link back, and you’ll actually get visitors. If you want your visitors to join the conversation, just pop over to Haloscan to sign up for free commenting and trackbacks. (Blogger also has comments now, but I’m not so fond of their system.) Continuing your search for free services, sign up with Sitemeter so that you can obsess over how many people are visiting, and who is linking to you. Very rewarding, I promise. At a slightly higher level of ambition, you can install software like WordPress or TypePad, either on your own machine, or at some web host you pay for. That’s what we’ve done here at Cosmic Variance, since the features of WordPress are especially useful for a group blog. And then if you’re extremely ambitious, you can put a lot of work into fine-tuning the look and feel of your blog template — or make it easy for yourself and hire Lauren to do it for you.

Of course there are too many blogs out there already, so it’s not as if I’m encouraging people. Only the right people. Actually, there’s no reason why everyone can’t have multiple blogs, serving different purposes. I don’t have an especially clear view of what the blog landscape will look like ten or twenty years down the road, except that it will be substantially more active and diverse than it even is today. You don’t want to miss out, do you?

The View of the Universe from the Nevada Desert

The first-ever YearlyKos get-together has now come and gone. For me it was an interesting experience on several levels. First and foremost, it was an opportunity to meet in person several bloggers whose work I had long admired from afar: PZ Myers of Pharyngula, Chris Mooney of The Intersection (and The Republican War on Science), Lindsay Beyerstein of Majikthise (a guest blogger from way back), Stephen DarkSyde of Daily Kos and Unscrewing the Inscrutable, and a number of others. Only secondarily, I kicked butt at the Riviera poker tables, held my own at slightly higher limits at the Wynn, and got destroyed at the MGM Grand.

There was a great feeling of history being made — a real-life collection of committed political bloggers and diarists, talking politics and ideas and strategies and generally trying to figure out how to move things forward from these early days of promise in which the blogosphere finds itself. And there were plenty of big names around to verify that something important was going on — Harry Reid, Wesley Clark, Bill Richardson, Mark Warner, Tom Vilsak, Howard Dean, Joe Wilson, Maureen Dowd. The place was thick with journalists, guaranteeing that the gathering would not pass unnoticed.

Deep down, though, I learned once again that an environment of political activism is not for me. I’ve volunteered and been active politically in very minor ways in the past, and I am always reminded that I should go back to academia where I belong. Of necessity, political action feeds on fervent commitment to the cause and a deep-seated conviction that one’s opponents are worthless scoundrels. Even when I do believe those things, I can’t quite give myself over to such stances uncritically. I’d rather contemplate the ins and outs of different aspects of an argument, even if I do end up resolutely on one side; politics (as opposed to governance) has little time for such nuances. At the same time, when I do take a position, I have little interest in softening its edges for political consumption, or reducing complexities to soundbites in order to convey a message. The complexities are the fun part! Don’t get me wrong; somebody has to do it, and I have incredible admiration for those who fight for the right side with passion and perseverance in the political arena. I just don’t want it to be me.

The good news is: science! Thanks largely to DarkSyde’s efforts, there was a substantial presence of science bloggers at YearlyKos. A “Science Bloggers Caucus” on Thursday night, which I expected to collect a dozen or so misplaced souls who weren’t interested in the gatherings sponsored by some of the big political blogs, instead packed a room to overflowing with over fifty energetic participants from a wide cross-section of demographics. The bad news is: politics! Even when the science bloggers got together, there wasn’t much (any) talk about the substance of science; it was all about how to combat skepticism of evolution and climate change and stem cell research and so on. Not that this was anything other than inevitable; it was a political-blogging conference, after all. The tragedy is that our society finds itself in a place where scientists need to waste time combatting Intelligent Design when they could be sharing exciting news about the latest developments in evolutionary theory. We do have to keep up this fight, but it’s important to simultaneously mix in a healthy dose of science for its own sake (which all the great science bloggers actually do), to remind people why it’s so fascinating and worthwhile in the first place.

Besides the Thursday science bloggers caucus, DarkSyde also organized Friday morning’s Science Panel, which was a smashing success. We heard talks from Chris and PZ, as well as Wendy Northcutt of the Darwin Awards and famous science supporter and retired four-star general Wesley Clark. Lindsay took pictures.

Wesley Clark

I enjoyed the talks a great deal. Chris gave an extremely polished and hard-hitting presentation, his skills obviously honed to a fine edge by months of book-touring. PZ warmed my heart by telling it like it is:

Some like to say America is a Christian nation. I think that misses the point: we have been and are a science and engineering nation. The riches we enjoy right now arose from invention and discovery and industry.

But it was Clark’s presence that was the biggest coup, and might have had something to do with the incredible attendance for a session that started at 8:00 a.m. on a Friday. (Although, as a matter of fact, almost everyone stood around to hear the rest of the talks.) I’ve always liked Clark as a prospective Presidential candidate, and the fact that he chose a venue devoted to science as the place to give his speech was a nice bonus. The speech itself was interesting and essentially completely extemporaneous. There was some expected stuff about how great America is, and how that greatness relies in substantial measure on our scientific expertise. But he also wasn’t afraid to address the complicated relationship between science, politics, and religion. He professed to believe in God, which is what you expect a politician to do (and is likely to be perfectly sincere, I have no idea), but went on to insist without hedging that religion should be kept clearly separate from both science and politics. He even brought up stories of officers in the armed forces who told soldiers that they would go to Hell if they didn’t believe in (the right) God — and said in no uncertain terms that those officers should be thrown in jail. (One interesting thing about being a prospective national candidate is that anything you say can potentially get you in trouble. To guard against this, you are followed everywhere by a handler who sits in the audience while you speak, ready with hand signals to let you know if you are treading onto dangerous territory and should skip to another subject. Apparently no such intervention was required during Clark’s speech. But I definitely need somebody like that to follow me around.)

Best of all, we learned that General Clark’s secret dream while growing up was to be a high-energy physicist! Only once he got to West Point did the realization dawn that one could not be both a career army officer and a working scientist; becoming Supreme Allied Commander in Europe for NATO must have been lukewarm consolation. (To be fair, he did mix up the inverse-square law with the equation for motion under constant acceleration, so perhaps he made the right career choice.) And, to my delight/horror, he went out of his way during his talk to mention the string theory landscape! You can’t make this stuff up. Clark brought up Leonard Susskind’s book The Cosmic Landscape as an example of the extraordinary ideas that contemporary physicists are contemplating in their efforts to make sense of Nature, and in particular as a warning against any claim that the origin of the universe could only be understood by invoking a God of the gaps.

There was a brief question period after Clark’s talk, but I did not rush to the microphone to explain that an anthropic resolution of the cosmological constant problem relied heavily on a problematic choice of measure on the space of observers in the multiverse. You would be proud of me.

“The Entire Planet!”

I had the great pleasure last night of meeting Melissa of Shakespeare’s Sister fame and some of the great cast of characters she has assembled over at her blog, including Mr. Shakes, Litbrit, Paul the Spud, and others. The occasion was a visit to our northern suburb of Evanston to catch Al Gore’s movie An Inconvenient Truth. In fact I had already seen the movie, but was more than willing to see it twice. I am quick to admit that I am not a Gore fan, and the thought of paying hard cash to see a movie that consists mostly of him giving a Keynote presentation (there was plenty of Apple product placement) falls somewhat below “drinks at Clooney’s villa in Tuscany with the gang” on my list of exciting ways to spend an evening.

But it turns out to be a great film, oddly compelling, with at least one priceless joke about gold bars. It’s not a science documentary — many graphs have no labels on their axes (much less error bars), and much of the evidence adduced is anecdotal and aimed at the gut rather than the brain. But what anecdotes they are. It’s hard to see pictures of Russian fishing boats stranded in a barren sandy landscape that once was a major lake bed without thinking that something needs to be done.

There isn’t any scientific controversy over whether or not climate change is happening, or whether or not human beings are a major cause of it. That argument is over; the only ones left on the other side are hired guns and crackpots. But the guns are hired by people with an awful lot of money, and they’re extremely successful at sowing doubt where there shouldn’t be any.

Their task is made easier by the fact that the atmosphere is a complicated place, and the inherent difficulties in modeling something as messy as our climate. But climate models are not the point. The point is not even the dramatic upward trend in atmospheric temperature in recent years. The actual point is made clear by the plot of atmospheric CO2 concentration as a function of time, which I just posted a couple of days ago but will happily keep posting until I save the planet.

CO2 concentration

Here is the point: We are taking an enormously complex, highly nonlinear, intricately interconnected system that we don’t fully understand and on which everything about our lives depends — the environment — and repeatedly whacking it with sledgehammers, in the form of atmospheric gasses of various sorts. Statements of the form “well, we don’t really know what that particular piece of the system does, so we can’t be rigorously certain that smashing it with a sledgehammer would necessarily be a bad thing” are, in some limited sense, perfectly true. They are also reckless and stupid. The fact that there are things we don’t understand about the environment isn’t a license to do whatever we like to it, it’s the best possible reason why we should be careful. And being careful won’t spell the doom of our economic system, bringing global capitalism crashing to the floor and returning us all to hunter-gatherer societies. We just have to take some straightforward steps to mimimize the damage we are doing, just as we very successfully did with atmospheric chloro-fluorocarbons to save the ozone layer. And the best way to ensure that those steps are taken is to elect leaders who are smart and determined enough to take them.

Blogs!

Some new-ish physics-y blogs that you might not know about, but are worth checking out. (How do I know about them? Probably because at some point they linked to CV. Not that I ever check.)

  • Backreaction is a group blog, I think by some physics grad students mostly postdocs. Sabine Hossenfelder seems to be the lead conspirator. Great fun posts, full of interesting physics.
  • physics musings, subtitled “the tale of a physicist’s comeback.” Jao (Jose Antonio Ortega Ruiz) got a Ph.D. in gravitational-wave detectors, left the field, and has now been inspired to get back in.
  • Charm &c. is by an experimentalist at Cornell, apparently working at Fermilab. Otherwise mysterious.
  • Sexy Science is like Us magazine, for science. No physicists yet! Outrageous.
  • Galactic Interactions is by occasional CV commenter Rob Knop. Articles about tenure and funding are must-reading.
  • Brad Hoc is not entirely serious, but still he should post more. He’s single ladies!

Just a small sample of relatively new blogs that I happened to have noticed. As of this moment, Cosmic Variance is arguably the largest physics-oriented blog on the web. But the idea is just catching on, and I wouldn’t be at all surprised if we were overtaken at some point sooner rather than later. Which is great — let everyone do their thing, and the quality stuff will bubble to the top.

If you have your own science-type blog that you’d like to plug, or know of some good ones that deserve wider recognition, consider this thread the place to be shameless.

Kosmos

Kosmos Before there were blogs, there were things called “books” that people would carry around with them in order to occasionally read the words printed inside. In a clever bit of cross-platform fertilization, DarkSyde and DevilsTower (Mark Sumner) from Daily Kos have put together a collection of science posts into a new book, Kosmos: You Are Here. They’ve included original illustrations by artists Carl Buell and others, as well as interesting exerpts from the comment threads of the original posts. DarkSyde is a great science writer, so I imagine the book is worth reading for the actual content as well as representing an exciting new-media experiment.

And before there were comment threads, there were events called “conferences” where actual human beings would gather in a common location to exchange ideas and patronize the local drinking establishments. This summer will witness the first ever YearlyKos, a gathering of bloggers at a small Nevada resort town on June 8-11. (Don’t ask me why “Daily Kos” is two separate words while “YearlyKos” has no spaces. For some reason, people type in a few URL’s and suddenly they think that spaces are an antiquated typographical anachronism.) Should be a fun event; celebrities to attend include Harry Reid, Ambassador Joseph Wilson, PZ Myers, and Chris Mooney. Hopefully there will be something to do to fill the downtime between the interesting talks.
