The Core Ideas of Science

A National Academy of Sciences panel, chaired by Helen Quinn, has released a new report that seeks to identify “the key scientific practices, concepts and ideas that all students should learn by the time they complete high school.” An ambitious undertaking, but a sensible one. At the very least, efforts like this serve to focus attention on what’s important across a wide variety of K-12 curricula, and at best it could help prod schools (or states, really) across the country into teaching more coherent and useful science to kids. Here’s the web page for the report, a summary (pdf), and the report itself (pdf, free after you register).

So what are the core ideas of science? They are all listed in the summary report, and divided into three categories. The first category is “Scientific and Engineering Practices,” and includes such laudable concepts as ” Analyzing and interpreting data.” The second category is “Crosscutting Concepts That Have Common Application Across Fields,” by which they mean things like “Scale, proportion, and quantity” or ” Stability and change.” It’s great that the organizational scheme emphasizes ideas that stretch across disciplinary boundaries, but there is definitely a danger that the resulting items come off as a bit vague. The secret to success here will be how they can be implemented, with concrete examples.

The third category is the nitty-gritty, “Core Ideas in Four Disciplinary Areas,” namely “Physical Sciences,” “Life Sciences,” “Earth and Space Sciences,” and “Engineering, Technology, and the Applications of Science.” (Math is not within the report’s purview.) And here are the actual core ideas proposed for the physical sciences: …

Miss USA Contestants on Teaching Evolution

Now that Twitter and Facebook have been invented, I don’t usually put up blog posts that simply link to someone else’s posts. (Although I wonder if that policy is a mistake.) But this morning I put up a link to a post at Jerry Coyne’s blog, and it was almost immediately deleted from Facebook. (The Twitter entry was fine, of course.) I wouldn’t even have known, except that someone commented that it had been “flagged as inappropriate by Facebook users.”

Of course, Facebook being Facebook, I have no idea whether this is a nefarious conspiracy or simple incompetence. Probably both. In any event, you should go check out the post, which comments on this YouTube video.

It’s a compilation of the answers given by contestants in the Miss USA contest to a simple question: “Should evolution be taught in schools?” Miss California, Alyssa Campanella, who eventually won the contest, gave a strong pro-science answer that will bring a smile to your face. At least, if you are finished crying and throwing objects at your computer monitor after seeing some of the other answers. Due to the vagaries of alphabetical order, Miss Alabama comes first, and it’s not pretty.

For the most part, the contestants are interested in being good politicians and keeping everybody happy, not in staking out courageous stances in the science/religion debates. But that’s exactly what’s so depressing: here we are, in the most advanced country in the world (albeit in its waning years), and it’s considered controversial whether we should teach science to our children. The question wasn’t even “should we teach creationism,” which is actually a harder issue (although still very easy). It was just whether we should teach straightforward science at all. Very sad indeed.

The Mighty THOR

I know everyone is excited about this weekend’s premiere (at least here in the U.S.) of Thor, the latest superhero extravaganza from Marvel studios. At least I am, for my usual selfish reasons: I helped do some consulting (through the Science and Entertainment Exchange) for the movie. Also, there is a mystical hammer that smashes things; what’s not to like?

Thor - Trailer 2 (OFFICIAL)

Unlike TRON: Legacy, where we came in after the screenplay had been drafted, on Thor we came in near the beginning. Marvel had done a lot of work on the idea, but there wasn’t yet a script. The Exchange set up a consult meeting with director Kenneth Branagh, the screenwriter, and few people on the design and production side of things, along with three scientists — Jim Hartle from USCB, Kevin Hand from JPL, and myself.

We bandied around lots of issues relating to the Thor universe and how it fit in with Marvel’s bigger plans. Once there was a script, I came in to read it and offer some more comments. Since that time, the script was re-written by the dynamic duo of Ash Miller and Zack Stentz, and I haven’t actually seen the film yet, so I can’t speak to what kind of impact we had in the end. Let’s just say that there was one thing in particular that they were planning on doing in the movie that drove all the scientists batty — I think we convinced them to fix it, but we’ll have to see. And once filming started, they recruited Caltech student Kevin Hickerson to help with the tech-gadgetry end of things. So I have high hopes. (Early reviews are very positive. And of course, Agent Coulson returns, with a larger role than in the Iron Man films. Everyone loves Agent Coulson.)

You might be wondering, where is there room for any sort of science in a comic-book movie about a Norse god in a red cape who swings a magical hammer? Well I’m glad you asked. Actually there were a couple of different things where the movie people were very interested in our input. One was constructing a coherent framework for the Marvel universe — ultimately, this story about Thor the thunder god is going to have to be compatible with Tony Stark’s Iron Man world, since the two characters are both part of the Avengers. (I also got to read the script for that, and yes — it is as great as the rumors suggest.)

Kevin Feige, president of production at Marvel Studios, is a huge proponent of having the world of these films ultimately “make sense.” It’s not our world, obviously, but there needs to be a set of “natural laws” that keeps things in order — not just for Iron Man and Thor, but all the way up to Doctor Strange, the Sorcerer Supreme who will get his own movie before too long. The thinking here is very much based on Arthur C. Clarke’s “any sufficiently advanced technology is indistinguishable from magic.” In the trailer above, Thor basically gives exactly this pitch to Jane Foster.

That’s the other area where we science consultants were able to help out: …

Sir Martin Rees Wins the Templeton Prize

The Templeton Prize has to be the most efficient publicity campaign ever. The Templeton Foundation gives a million British pounds to a scientist who is willing to say that science and religion are compatible, and in return they get many times that value in publicity. (The formal citation is “for making an exceptional contribution to investigating life’s spiritual dimension”) Atheists should really just refuse to talk about it, but — can’t resist!

This year’s winner is Sir Martin Rees, one of the world’s leading theoretical astrophysicists. Like everyone else, I have nothing but enormous respect for Sir Martin’s work. He focuses mostly on “physical” cosmology — that part that involves actual known laws of physics, like galaxy formation — but is more willing than most folks in that game to think about speculative ideas concerning the multiverse and the Big Bang. He describes himself as non-religious but church-going, and would rather science and religion just get along than be constantly at each other’s throats. You can read an extremely awkward interview with him by Ian Sample in the Guardian — it’s clear Rees has no interest at all in talking about science/religion issues, but that’s going to come up when you win the Templeton prize.

But the really telling thing is this companion piece at the Guardian‘s website by Mark Vernon. (Another piece by Jerry Coyne provides some balance.) The real problem with the Templeton Foundation, in my view, is that it works very hard to give people a false impression that science and religion are actually reconciling, not just that they should be. If you want to see the publicity machine at work, this piece is a perfect example. Here’s the money paragraph:

But with Rees’s acceptance, the substantial resources of the Templeton Foundation have, in effect, been welcomed at the heart of the British scientific establishment. That such a highly regarded figure has received its premier prize will make it that little bit harder for Dawkins to sustain respect amongst his peers for his crusade against religion.

There you go — now that such a distinguished and respectable scientist has accepted the Templeton Prize, we may conclude that “the British scientific establishment” is rejecting Dawkins and his fellow noisome atheists in favor of warm and fuzzy Templetonianism. That’s exactly the publicity effect they are hoping for.

In unrelated news, Mark Vernon spent time at Cambridge in a journalism fellowship paid for by the Templeton Foundation. Have to hand it to them, these guys know how to get a message out.

A Sense of Doubt

Jerry Coyne, cheerful fire-breathing atheist that he is, gets invited to a church to talk about evolution. That’s not how it worked out, as people were more interested in talking about the relationship between science and religion. You can guess what happened — or maybe not. There was a productive two-hour conversation in which both sides learned something.

That’s pretty much the same thing that happened when I visited a Chicago church back in the day. There’s obviously a selection effect at work: the kinds of churches that invite atheists in for conversations are generally ones that enjoy some kind of open dialogue. Not that it’s all warm hugs and pleasant disagreement; I noticed that the older generation in my audience was a lot less open to even thinking about some of the points I raised, while Jerry had to fend off someone who thought that math and science had led to Nazi Germany.

Jerry concludes that the harmful aspects of religion are correlated with the certainty displayed by its adherents. This is a true but subtle point, as of course there are those who love to accuse scientists and/or atheists of unwarranted certitude. I think the difference is that we feel relatively sure about some things, while we’re quite ready to admit that we don’t know the answer to other questions, and we have a clear notion of where the distinction lies. But I would think that, wouldn’t I?

Conversations like these are enormously helpful. The trick is that it’s much easier — on both sides — to be polite and interactive in person, while the temptation to lecture people from on high is irresistible in other contexts, where it’s easier to think of the opposition as cartoons rather than real people.

Scientists Aren’t Always Complete Idiots

I don’t like to spend too much time highlighting and making fun of silly things on the internet; it’s not like they are going to be stamped out by a few well-placed blog posts. But this awful little article by Chris Ormell in Times Higher Education merits an exception. It has been ably demolished Jon Butterworth at the Guardian, but is worth revisiting, because its badness illuminates a larger point. (Via @astroparticle.)

Ormell’s thesis is laid out at the start:

Mathematics tends to be both misunderstood and credited with magic powers, especially by those who are intelligent but not mathematically inclined. Arising from this, there is a perennial temptation for mathematicians to play to the gallery and to assume the role of magicians and, even more temptingly, high priests.

The worrisome sign here is not the explicit content, which is vague enough to be unobjectionable, but the gleeful indulgence in overgeneralization. It seems clear that what we are in for is a broad denunciation of mathematicians and their ilk, not a nuanced appreciation. The devil will be in the details.

We have seen blind faith in mathematics in action recently. In addition to the contribution of mathematical models to the great credit crunch of 2008, take physicist Stephen Hawking’s claim that philosophy is dead. The reason he gave was that philosophers have stopped bothering trying to understand modern mathematical cosmology. This cosmology is based on current mathematical physics, most of which has been in place for less than 100 years. It is an impressive edifice of concepts and mathematical models, but one that has not yet built up a track record for reliability over a thousand years, let alone a million years.

Hawking’s claim that philosophy is dead was silly, but not nearly as silly as this. I’m not sure what the implication is supposed to be — we shouldn’t trust sciences that don’t have a thousand-year track record of reliability? Since that includes almost all of contemporary science except for a bit of astronomy, we’d be living in primitive circumstances indeed. The “million years” criterion is even more awesome. That means we shouldn’t trust things like “writing,” or for that matter “human beings.”

Edge World Question Center: Your Cognitive Toolkit

This year’s edition of the Edge World Question Center asks: “What Scientific Concept Would Improve Everybody’s Cognitive Toolkit?” There’s quite a collection of contributions, many from scientists but also from writers and an assortment of unclassifiable big thinkers.

I haven’t carefully perused all of the entries. As you do, please chime in with any that you think we should all be paying attention to. At a brief glance, here are some that caught my eye:

I have a contribution of my own, The Pointless Universe, after Steven Weinberg’s quote. Need to come up with better branding if this idea is really going to take off.

Is Al Gore Responsible for Destroying the Planet?

Among the many depressing aspects of our current political discourse is the proudly anti-science stance adopted by one of our major political parties. When it comes to climate change, in particular, Republicans are increasingly united against the scientific consensus. What’s interesting is that this is not simply an example of a conservative/liberal split; elsewhere in the world, conservatives are not so willing to ignore the findings of scientists.

Republicans are alone among major parties in Western democracies in denying the reality of climate change, a phenomenon that even puzzles many American conservatives. Denialism is growing among the rank and file, and the phenomenon is especially strong among those with college degrees. So it doesn’t seem to be a matter of lack of information, so much as active disinformation. Republican politicians are going along willingly, as they increasingly promote anti-scientific views on the environment. After the recent elections, GOP leaders are disbanding the House Select Committee on Global Warming.

What makes American conservatives different from other right-wing parties around the world? Note that it wasn’t always this way — there was a time when Republicans wouldn’t have attacked science so openly. I have a theory: it’s Al Gore’s fault.

Actually it’s not my theory, it comes from Randy Olson. For a while now Randy has been vocally skeptical about An Inconvenient Truth, Gore’s critically-acclaimed documentary about global warming. I was initially unconvinced. Surely the positive effects of informing so many people about the dangers of climate change outweigh the political damage of annoying some conservatives? But Randy’s point, which I’m coming around to, was that for all the good the movie did at spreading information about climate change, it did equal or greater harm by politicizing it.

By most measures, Al Gore has had a pretty successful career. Vice-President during an administration characterized by peace and prosperity, winner of the popular vote total during his Presidential run, co-founder of Current TV, winner of an Emmy, a Grammy, and a Nobel Prize. But to Republicans, he’s a punchline. It’s an inevitable outcome of the current system: Al Gore was the Democratic nominee for President; therefore, he must be demonized. It’s not enough that their candidate is preferable; the other candidate must be humiliated, made into a laughingstock. (Ask John Kerry, whose service in Vietnam was somehow used as evidence of his cowardice.) The conclusion is inevitable: if Al Gore becomes attached to some cause, that cause must be fought against.

Here is some evidence. You may think of Jay Leno as a completely vanilla and inoffensive late-night talk-show host. But he’s a savvy guy, and he knows his audience. Which is mostly older, white, suburban middle-class folks. Which political party does that sound like? Between January and September of 2010, Jay Leno made more jokes about Al Gore than about Sarah Palin. You read that right. This is while Palin was promoting books, making TV specials, stumping for candidates, and basically in the news every day, while Gore was — doing what exactly?

Once Al Gore became the unofficial spokesperson for concern about climate change, it was increasingly inevitable that Republicans would deny it on principle. This isn’t the only reason, not by a long shot (there’s something in there about vested interests willing to pour money into resisting energy policies that are unfriendly to fossil fuels), but it’s a big part. Too many Republicans have reached a point where devotion to “the truth” takes a distant back seat to a devotion to “pissing off liberals.” With often nasty implications.

What the United States does about climate change will be very important to the world. And what the U.S. does will be heavily affected by what Republicans permit. And Republicans’ views on climate change are largely colored by its association with Al Gore. As much as I hate to admit it, the net real impact of An Inconvenient Truth could turn out to be very negative.

Gore himself doesn’t deserve blame here. Using one’s celebrity to bring attention to an issue of pressing concern, and running for office in order to implement good policies, are two legitimate ways a person can help try to make the world a better place. In a healthy culture of discussion, they shouldn’t necessarily interfere; if any issue qualifies as “bipartisan,” saving the planet should be it. But in our current climate, no discussion of political import can take place without first passing through the lens of partisan advantage. Too bad for us.

Here’s What Needs to be Explained

The results from this weekend’s question are in: “What is the one concept in science that you really think should be explained better to a wide audience?” I tried to collate the answers from Twitter and Facebook as well as here, at least up to the point where my patience evaporated. Answers below the fold, grouped into three categories: big concepts, specific ideas, and meta issues.

Scott Aaronson wrote, “The skill of sharpening a question to the point where it could actually have an answer.” Which is a skill I should probably try to develop myself, as the question I asked was amenable to different interpretations. Many people answered “evolution,” but as Ed Yong pointed out on Twitter, evolution is actually explained quite well in many places. So when we ask what needs to be explained better, there are at least two issues at work: what we actually do a bad job at explaining, and what doesn’t succeed at penetrating out into the public consciousness. In contrast with evolution, for example, I would say that quantum mechanics is explained in many places, but very rarely is it explained well.

The winner by a wide margin was the meta issue of “the scientific method.” Which raises another question: do we agree on what the scientific method is? I suspect not. But I am completely on board with the idea that “how science works” is not explained very well, and possibly a higher priority than any particular scientific concept.

Others that did well: evolution, statistics, certainty/uncertainty, entropy, quantum mechanics, time, and gravity. I cannot refrain from pointing out that these last four were all addressed at some length in From Eternity to Here. Which makes me think that what people are really saying is, “more folks should read Sean’s book.” Only 40 more shopping days ’till Xmas…

Also of note is that there wasn’t actually a great deal of consensus; the list of concepts that came up is quite long. Clearly we need to do a better job of explaining.

Here are the answers:
