WMAP 5-year results: live lecture
Yesterday, Sean Caroll wrote an informative post about the WMAP 5-year data release. This morning at 9:30am (local time) Perimeter Institute will be doing a live broadcast of a talk on the subject by Eiichiro Komatsu of the WMAP team. A second live broadcast will follow Saturday at 2:10pm.
More things everyone should know about science
Chad Orzel has a great response to Eva’s question for SciBarCamp, “What are the ten things everyone should know about science?”:
I have three suggestions, which are really all part of one big idea:
1) Science is a Process, Not a Collection of Facts The essence of science, broadly defined, is that it is a systematic approach to figuring out how the world works:
1. look at the world around you
2. come up with an idea for why it might work that way.
3. test your idea against reality.
… making sure you do everything in your power to prove your idea in 2 wrong. When it’s your own ideas you’re testing, the easiest person in the world to fool is yourself.
(I know Chad didn’t intend this as a complete description, and I feel like I’m being pedantic with my addition. I’m on a bit of a kick right now thinking about how biases, especially confirmation bias, affect our view of the world, and how important skepticism is to the conduct of science.)
4. tell everybody you know the results of the test.
Put those steps together, over and over, and you have the best method ever devised for increasing our store of reliable knowledge. The precise facts found by this method are not as important as the process for finding them– given the process, and enough time, you can reconstruct whatever facts you need. The facts without the process are worse than useless, they’re dangerous.
2) Science is an essential human activity. You’ll often hear people who study art and literature wax rhapsodic about how the arts are the core of what makes us human– Harold Bloom attributes it all to Shakespeare, but you can find similar arguments for every field of art. Great paintings, famous sculptures, great works of music (classical only, mind– none of that noise you kids listen to)– all of these are held to capture the essence of humanity.
You don’t hear that said about science, but you should. Science is essential to our nature, because at its most basic, science consists of looking at the world and saying “Huh. I wonder why that happened?” Science is applied curiosity, and there’s no more human quality than that. (“Bloody-mindedness” is a close second.)
(And, from a purely practical point of view, science and the products thereof are the reason why we have the free time to sit around making and appreciating works of art. Without science, we’d still be plains apes scavanging the kills of more efficient predators than us.)
3) Anyone can do science. Science doesn’t depend on race and it doesn’t depend on gender. You don’t need to be rich to do science. You don’t even need to be good at math.
And, I might add, you don’t need to be “smart”. Every 3 year old kid pretty much applies the scientific method as Chad describes (well, they don’t usually publish). Scientists are just a lot more systematic and dedicated than most people. If there’s something that distinguishes them it’s that they appreciate the scientific method, and understand what goes wrong when you start to vary steps.
Science is, fundamentally, nothing more than a systematic approach to looking at the world around us and figuring out how it works. Money and mathematics are tools that can help with this process, but the core of the enterprise is nothing more than a habit of mind.
One of the most pernicious lies told by our culture is that science is an elite and exclusive activity only available to a few. It leads to scientists being stigmatized as “nerds” or “geeks,” set apart from the rest of humanity, and it leads to tenured professors with Ph.D.’s in the humanities to say with a laugh “I just don’t understand science.”
Science does not require innate abilities beyond the standard-issue human genome. If you have the full complement of senses and a brain, you can do science. In fact, the core business of humanities scholars– sifting through texts looking for evidence to support a particular argument– is not really any different than the business of science. You come up with a theory of what’s going on in a particular work of literature, and then you check to see whether that holds up by systematically evaluating the evidence found in the text. That’s one step removed from doing science.
You may not understand a particular set of facts produced by science, but see point #1 above: Science is a process, not a collection of facts. You won’t necessarily understand all the facts of a particular science outside your own field of expertise– I don’t understand microbiology worth a damn– but if you have the brain power necessary to function as an autonomous adult, the process is within your grasp.
And again, if you have the process, you have the ability to eventually understand the facts. I don’t understand microbiology, because I haven’t been trained in those facts, but I know that I could understand it, and if I ever need that understanding, I know the process by which to get it. For that matter, I don’t understand feminist literary criticism, but I know that I could if I needed to, using the same mental toolbox.

John Francis on the value of silence
John Francis decided to stop speaking for seventeen years (one of only many remarkable things he’s done). Here’s part of an interview with Mark Hertsgaard, where Francis talks about the personal effect of his decision to stop speaking:
Interviewer: I’m going to read a passage from your book about your decision to stop speaking: “Most of my adult life I have not been listening fully. I only listened long enough to determine whether the speaker’s ideas matched my own. If they didn’t, I would stop listening, and my mind would race ahead to compose an argument against what I believed the speaker’s idea or position to be.”
Francis: That was one of the tearful lessons for me. Because when I realized that I hadn’t been listening, it was as if I had locked away half of my life. I just hadn’t been living half of my life. Silence is not just not talking. It’s a void. It’s a place where all things come from. All voices, all creation comes out of this silence. So when you’re standing on the edge of silence, you hear things you’ve never heard before, and you hear things in ways you’ve never heard them before. And what I would disagree with one time, I might now agree with in another way, with another understanding.
Mass scientific literacy
Here’s Eva Amsen’s idea for a event at SciBarCamp:
My idea: find 4 or 5 volunteers from different backgrounds to sit on a 20 minute panel and (with audience feedback) make a list of Ten Things Everyone Should Know About Science. Since we have a wide audience, this hopefully would be a varied list. Actually, maybe we could just put up a large sheet of paper and have people write down what they think should be on the list and get back to it later.
It’s a really interesting idea, and relates to the question in my last post about finding ways to better incorporate science into public policy.
My number one suggestion for Eva’s list is a deep practical understanding of how science works: what it means to know something, how something comes to be known, the provisional nature of all knowledge, the need to be aware of our own biases, and so on.
A sign that this is curretly lacking is the enormous pressure climate scientists are under to present a clear and simple story to the public about climate change. If they admit to uncertainty or complexity, it is seized on by their opponents as evidence that climate change is not happening. Yet such uncertainty is an essential part of the scientific process. One must confront it head on to get at the truth, and a public discourse in which this uncertainy is absent cannot possibly reflect the underlying truth; in a democracy, this means that science can play at most an indirect role in decision making. In a letter Richard Feynman explains how a colleague once saw through to where the truth lay between two competing points of view, one simple and clear, the other complex:
He smiled and reminded me he was an expert on judging evidence in difficult physics experiments. In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth
In his wonderful review of Ed Hutchins’ book “Cognition in the Wild” (read the whole thing!), Cosma Shalizi writes of the amazing things enabled by mass literacy. I wonder what changes in civilization would be enabled by mass scientific literacy? Here’s Cosma:
The nineteenth century, and to a lesser degree this one, have witnessed a dramatic expansion in the numbers of us engaged in administration, bureaucracy, management, oversight – that is to say, in formally-organized tasks of collective cognition and control. We did not invent bureaucracy, the mainstay of the ancient empires, but we’re much, much better at it than they were. A random American town of 200,000 – Piffleburg, WI, let us say – will have police, a rescue squad, a fire department, a hospital, universal schooling, several large factories, insurance offices, banks, a community college, a public library with several thousand volumes at least, a post office, public utilities, political parties, garbage collection, paved and usable roads everywhere, mercantile connections stretching across the country, and, with some luck, unions. These are corrupt, inefficient institutions which work poorly; every election, Piffleburg’s citizens mutter something like “what do we pay taxes for anyway?” Yet to run any one of these institutions at the level of honesty, efficiency and efficacy which makes Piffleburg grumble would have demanded the full powers and attention of even the ablest Roman propraetor or T’ang magistrate. That all of those institutions, plus the ones not restricted to a single city, could be run at once, and while governed by a very ordinary slice of common humanity, would have seemed to such officials flatly impossible.
The immediate question this raises, of why we are so much better at collective endeavors than the ancients, can be answered fairly simply. To a first approximation, the answer is: brute force and massive literacy. We teach nearly everyone to read and write, and to do it, by historical standards, at a high level. This lets us staff large bureaucracies (by some estimates, over 40% of the US workforce does data-handling), which lets us run an industrial economy (the trains run on time), which makes us rich enough to afford to educate everyone and keep them in bureaucratic employment, with some surplus left over to expand the system. This would do us no good if our ideas of administration were as shabby as those of our ancestors in the dark ages, but they’re not: we inherited those of the ancient empires, and have had quite a while to improve upon them (and improvements are made easier and faster by the large number of administrators and the high standard of literacy). Among the improvements are many techniques (standardized procedures, standardized parts, standardized credentials and jobs, explicit qualifications for jobs and goods, files, standardized categories) and devices (forms, punch cards, punch card tabulators, adding machines, card catalogs, and, recently, computers) for making the administration of people and things easier.
Questions
I’m really excited – in a couple of weeks I’ve got an opportunity to talk with and ask questions of an incredibly diverse and interesting group of 100+ people at SciBarCamp. So I’ve been thinking about what sorts of big picture questions I find most interesting, and trying to prime myself in preparation. I decided to write a few down, mostly outside the list of familiar standards – how did life begin, how did the Universe start, and so on. I’ve written the post with a view towards SciBarCamp, but of course I’m interested in hearing everyone’s thoughts! If you are coming to SciBarCamp, I’d also love to hear about some of the things you’d like to hear about at SciBarCamp.
What role can science play in public policy?
This question bugs the heck out of me, since loads of important public policy decisions are made without an appreciation of relevant scientific input. There’s a standard litany of solutions people offer to this problem – “more focus on science literacy”, “more outreach”, “educate the decision makers”, “run for office”, and so on. All these answers are worthwhile, but none seem to me to get to the core issue: either we need to find a system that works differently and better than democracy, or else we need to find some way of integrating science into the heart of the polity. I don’t know how to do either of these things, but I’d like to know what other people think about it.
What are the best ways to organize groups for collective creativity?
Kevin Kelly has a couple of mind-expanding stories about collective creativity:
In 1990 about 5,000 attendees at a computer graphics conference were asked to operate a computer flight simulator devised by Loren Carpenter. Each participant was connected into a network via a virtual joy stick. Each of the 5,000 copilots could move the plane’s up/down, left/right controls as they saw fit, but the equipment was rigged so that the jet responded to the average decisions of the swarm of 5,000 participants. The flight took place in a large auditorium, so there was lateral communication (shouting) among the 5,000 copilots as they attempted to steer the plane. Remarkably, 5,000 novices were able to land a jet with almost no direction or coordination from above. One came away, as I did, convinced of the remarkable power of distributed, decentralized, autonomous, dumb control.
About five years after the first show […] Carpenter returned to the same conference with an improved set of simulations, better audience input controls, and greater expectations. This time, instead of flying a jet, the challenge was to steer a submarine through a 3D under-sea world to capture some sea monster eggs. The same audience now had more choices, more dimensions, and more controls. The sub could go up/down, forward/back, open claws, close claws, and so on, with far more liberty than the jet had. When the audience first took command of the submarine, nothing happened. Audience members wiggled this control and that, shouted and counter-shouted instructions to one another, but nothing moved. Each person’s instructions were being canceled by another person’s orders. There was no cohesion. The sub didn’t budge.
Finally Loren Carpenter’s voice boomed from a loudspeaker in the back of the room. “Why don’t you guys go to the right?” he hollered. Click! Instantly the sub zipped of to the right. With emergent coordination the audience adjusted the details of sailing and smoothly set off in search of sea monster eggs.
Collective creativity is at the beginning of a long boom (look at Wikipedia go!), and it seems there are lots of new opportunities for collective creativity in science, the arts, and other areas. I’d love to hear good ideas about collective creativity at SciBarCamp, perhaps from a programmer like Reg Braithwaite, whose experiences seem to me to blend much of what it means to be creative in both science and art, or maybe from a Jazz musician like Isaac Ezer.
How is the web going to impact the process and institutions of science?
This is, of course, a question of great personal interest to me; I think we’re at the start of a major revolution in the processes and institutions of science. It seems like nearly all the participants are going to have interesting things to say about science and the web, including people like science blogger (and SciBarCamp co-conspirator) Eva Amsen, synthetic biologist (and promoter of open biology) Andrew Hessel, and Troy McConaghy, who does all sorts of amazing science-related stuff in Second Life.
I have about 50 other questions I’d like to add to my list, but if I do so this post will stop being a blog post, and will instead turn into a rather peculiar book, so perhaps I should stop there. One final question that I can’t resist because it’s so personally important for me: how do people manage their creative lives? This includes things like finding the discipline to do creative work, keeping the wolves of distraction and unfortunate obligation at bay, and managing all the information and decisions we seem to labour under. I’d sure like to hear other people’s experiences and ideas about all these things.
How to run an unconference: 20 useful online resources
As part of helping out with SciBarCamp, I’ve been studying other people’s experiences with unconferences. This post is a collection of some of the more useful links I’ve found.
- Foo Camp 2007
- The wiki for Foo Camp 2007. Great prototype if you’re thinking of running an event. Note that wikis for previous (and presumably future) Foo Camps are linked at the bottom of the page.
- Wikipedia: Unconference
- The article is a bit disorganized (as at 29 Feb 2008), but the links at the bottom on participation methodologies are stimulating.
- openspaceworld.org
- Open Space is a methodology for running meetings closely related to unconferences. It’s a bit more venerable, and has a different (though overlapping) community associated to it. This website is a clearinghouse of ideas on Open Space.
