Twice now, Mythbusters has tackled the story of Archimedes' "heat ray." Twice now it's been busted. So who could have persuaded them to revisit it a third time? ...President Barack Obama.

Adam Savage and Jamie Hyneman were guests at the recent White House Science Fair, where the three announced Obama's upcoming appearance. The fair, like Obama's guest spot, was designed to promote the importance of math and science education in America's schools. But Obama also may be something of a fan -- he's already taped his episode, and confessed to the audience that he was "a little frustrated" that he didn't get to blow anything up.

Other presidents have made cameo appearances on television shows, including Bill Clinton on MTV, Richard Nixon on Laugh-In and George W. Bush on Deal or No Deal.

Whenever British Prime Minister's appear outside of the context of Westminster - and particularly when aping some popular culture trope at the urging of some underling or another - it makes me cringe so hard that sometimes I fear that my teeth are going to implode.

The death ray episodes alway left me a bit disappointed. I mean take a 1 sq meter bronze sheild polished and concave and determine the amount of reflected radiation. Consider alternative designs, whitewashed lime springs to minds. Calculate the losses over the distance of 250 meters and determine watts on target. Then scale up until you have driven enough btus for ignition of canvas or sail in under 10 seconds. Then triple your design for death ray effect. Watch the enemy navy go up in smoke as long as they attack on a clear day.

Khrushchev was our president for three weeks in 1964 due to an extraordinarily embarrassing bureaucratic mix-up. It's scarcely remembered by historian, due to an extraordinary cover up that mostly involved everybody getting really quiet and embarrassed when the subject is raised, like when you mention your uncle who is in prison at Christmas dinner. But linguists remember it, because it was the moment the word Czar started getting affixed to presidential advisers, the moment the word "vodka" entered the English language (previously it had been called "white whiskey,") and the moment we started calling prehistoric elephants "woolly mammoths," from the Russian word "mamont"; previously, they had been called Tusk Monsters.

Seriously, nobody thinks Mythbusters is pure science. In fact I'd go so far to say that it's only about 1% science, but the fact is it does attempt to test hypotheses using repeatable, controlled real-world circumstances and that makes it way more scientific than the 700 Club or Fox and Friends.

Fie on that. I recall from the MetaFilter podcast episode with Adam Savage that actual working scientists tend to love the show. The complaints about rigor, sample size, etc tend to come from laypeople complaining on message boards. Ahem.

The show is, at its core, about doing experiments rather than relying on authority or tradition, taking things on faith, or trying to derive an answer from assumptions and intuition. The takeaway points are that a) it is possible and desirable to discover truth through experiment, b) science can be used to answer all kinds of questions, not just the kind involving beakers and particle accelerators, and c) everyone can do experiments, not just some closed-off scientific priesthood. Those are all tremendously valuable lessons.

Around the same size hit as the one they took years ago, declining to air the one about how easy it is to crack credit cards.

In fact I'd go so far to say that it's only about 1% science

Really? Because when I watch Mythbusters, what I see is the veracity of a commonly-held belief of some kind taken as the hypothesis, and then an apparatus gets built to support and tests get done that either support or disprove the veracity of that hypothesis.

Modulo some blowing things up, which I believe we can all agree is right at the intersection of science and fun, what more do you want? These guys aren't doing sociology; having them say "well, according to our sample of 2000 people, 28% of the time, they'll select radio-detonator A over bazooka B, normalizing for age and gender", or whatever, because that's crappy television. They're saying "will a cellphone blow up a gas pump?", putting cellphones all over gas pumps, and determining that the answer is no.

The thing that makes them great, and I'm sure the envy of scientists everywhere, is that at the end of that they'll say "We have this gas pump here not doing anything, and if cellphones won't blow it up, we will", and then kaboom, because explosions are fun.

That doesn't make their investigative process any less scientific. They make a verifiable hypothesis, construct a way to test it, run their tests and use the results to assert that their hypothesis is either correct or false. That's what science _is_.

I agree with you, but really, most of the show is tv show stuff, not them making a varifiable hypothesis and testing it. Slow-mo shots of explosions from different angles, bits about Adam or Grant throwing up due to motion sickness, commercials, that stuff makes up most of the air time. I'm not complaining, I'm just saying the science part may be the overarching theme but it is not the majority of the content.

But, hey, if you want two guys in a lab doing highly controlled, low-budget, sedate physics, there's plenty of that on YouTube too.

Like some others, I will happily defend Mythbusters against charges that it is not "science." I use the scare quotes because the reality is that science is a great many things - it is a philosophy of knowledge, a profession, a collection of techniques to learning, a historically-contingent way of knowing the world, a label for a self-correcting and self-revising knowledge base, and is frequently used as a shorthand for "rationality." Of course Mythbusters isn't an embodiment of all of those but it is fundamentally a good thing because it teaches curiosity about the world and shows it is possible to not only to wonder about the world but to get off your a** and figure out how the world works. And most of the experiments are very do-able or at least understandable to the vast majority of the audience, which is no mean feat.

To me Mythbusters is the best show I have ever seen to illustrate experimental science - that the answers are out there is you would only look. (History Detectives is also great and does the same thing for the historical sciences). The show reaches pinnacles of awesomeness with the revisit-the-myth shows which mirror the peer-review process and internal deliberations that constitute science-as-a-profession. So yes, they don't tackle problems to the same depth as some scientific research does but they show the fundamental approach one would use to get there.

(I would also add that in the experimental wing of my own field, archaeology, there are many papers that are frequently cited that are less involved than a typical Mythbusters experiment. If they ever decided to they could make a huge dent in some of the questions we have about ancient technology with just a few shows. Too bad throwing atlatls, breaking pots, burning wattle-and-daub houses, and butchering and transporting large mammals are probably not the most interesting to a TV audience.)

Clinton was on MTV in 1994. At that time MTV still had Alternative Nation, The Grind, MTV Unplugged, 120 Minutes, Top 20 Video Countdown, and Yo! MTV Raps. That's a fair amount of music.

I've always characterized Mythbusters as being a combination of science and Science! the science is the honest efforts to create repeatable, testable situations for evaluating a claim. The Science! is the resultant explosion of taking said situation to the logical (and wonderfully absurd) extreme.

clarknova: "1) Mythbusters isn't really science."

I think you misunderstand the difference between "not being science" and "not being all science". They're teaching the most vital fundamental of science: don't trust your instinct -- test. Just because they aren't demonstrating sample size and control groups and experiment sanitation doesn't mean they aren't doing science. A kindergarten teacher who's teaching the alphabet is teaching language even though they aren't showing how to identify and eradicate passive tense in five-paragraph essays.

The link to xkcd that device55 posted is perhaps the best response to questions about the validity of Mythbusters. I have always poo-pooed Mythbusters for their sloppiness, but from the standpoint of "basic" science, I think this is the best way to regard the show for it's essential value.

As for Archimedes heat ray, it's pretty clear he used a narrowband microwave emitter cobbled together from things he found lying around. Archimedes was the original MacGyver (cf. The Legend of the Holy Rose, part 2, Season 5).

The 10th Regiment of Foot writes "Seriously, nobody thinks Mythbusters is pure science."

Probably true for most people with a conception of Pure Science. But people without that conception think they are authoritative because they use experiments. The internet is rife with the expression "Mythbusters proved you can't blah blah blah" when often they have proven no such thing. A bit of searching would find that expression or words to that effect on AskMe. I have no problem when they prove something is possible as one successful experiment is all it takes. I love the "plug the pressure relief valve on a hot water tank and see it go sky high" episode. But when they say something isn't possible it is often after only the most cursory of attempts. My go to episode demonstrating this is one when they were trying to light some gas on fire with an obviously too rich mixture and their solution to non ignition was to pour on some more gas. Or when they "proved" a broken drive shaft can't catapult a car when all they proved was you probably can't catapult a 67 valiant. If Mythbusters were running in 1900 they'd easily "prove" that powered flight wasn't possible. They'd easily "prove" no one driving a car could survive a 150 mph impact with a brick wall or a free fall from 5K feet.

jedicus writes "Fie on that. I recall from the MetaFilter podcast episode with Adam Savage that actual working scientists tend to love the show. The complaints about rigor, sample size, etc tend to come from laypeople complaining on message boards. Ahem."

As above I have no problem with the show when they prove something possible. It's the authority they claim which is then accepted by other people when they say something isn't possible that grates.

But when they say something isn't possible it is often after only the most cursory of attempts.

Take the soda vs. windshield episode. "Naw, it just sort of bashed up the windshield a bit. Busted!" Wait--what? What if it's one of Jay Leno's antiques with a winshoield made of un-tempered, un-laminated glass? He'd totally die, right? Right?

The plane will fly. Get over it.

That's the exact opposite of what Mitheral's talking about. It would be as if the plane happened to not fly in their one test and they concluded that it could never fly.

There's a bunch of myths I'd like to see busted : )

Perez Hilton (or his ghostwriter) was snarking on this and saying the President should be paying more attention to solving the recession or unemployment or whatever instead of being on Mythbusters, and said that he was trying to be a celebrity. Seriously? I hate Perez Hilton now. This is the kind of stuff I've been seeing on CNN and all over the web the minute the president attends his kids' soccer game or goes to Hellburger or takes a bathroom break. I hate it when people say stuff like that. It's so irritating. Like solving the recession or unemployment is just about spending more thinking it out or whatever. There's finally a president who is a real, honest to God role model for American children, and people complain that he takes bathroom breaks. They never complained when Bush was out on vacation all of the time. It never bothered them that that guy could barely string a coherent sentence together, but President Obama can't make a cameo on television without people screaming that he's trying to be a celebrity.

OK, I finally signed up here indulge in an optics geek rant. The problem with calculations like humanfont's, above, is that the figure you need is not watts on target, but watts per square meter. There's a fundamental law of optics that says that because the sun's not a point source, you can never concentrate all of it's energy back onto a point-sized target.

In fact, if you stand at the target and look back, the surface brightness (watts per square degree is one measure) of an object like the sun, viewed through an optical system (the mirrors, lenses, or what-have-you that create the 'death ray', can never be higher than when you view the object itself.*

Take, for example, the ant on a sunny sidewalk under a mean kid's magnifying glass. When she looks back at the death ray that's about to annihilate her, she doesn't see the same size sun, grown many times brighter. Instead, the sun is the same brightness (again, per square degree) as it always was, but magnified so that it fills the burning glass. Since the lens is fairly small, but quite close, that means it fills up a lot of square degrees, and the poor ant has no chance.

What this boils down to is there are just two factors that influence the effectiveness of the 'death ray': how large the optics are, and how close you can get them. The ratio between size and distance measurements is (roughly) what optics nerds call 'focal ratio' or 'f-stop' and this the same argument explains why 'faster' lenses (with bigger optics) 'burn' an image into a film or sensor more quickly. Archimedes is left with a choice of making his death ray the size of the city, or getting it really close to the target. The same mirrors that will torch a ship held near at dockside, will barely light it up from miles away atop the mountain.

* Proving this law requires Hamiltonian math that I never quite learned, and an application of Liouville's theorem, but it's relatively easy to see that any system that could violate this law could be turned into a kind of of luminous perpetual motion machine. More importantly, you can test it yourself through experiment. Look through a magnifying class at a fairly dim extended light source (a frosted bulb on a dimmer, paper over an old flashlight, NOT THE SUN) and compare it to the original. Te magnified image is larger, but it will never be brighter.

anniecat: "Like solving the recession or unemployment is just about spending more thinking it out or whatever."

This is a lot like how I think about work. I'm suspicious of people who work 18-hour or 20-hour days every day every week. You end up seeing every problem as something that can be solved by throwing hours at it, not necessarily as something that can be solved through intelligent solutions.

Plutor i writes "The plane will fly. Get over it."

I've always been pro-plane taking off (though the question itself is insufficiently constrained and therefor the intent of the question is debatable.) However as kmz says that's not what I'm taking about. What I'm talking about is paulsc or others in his camp would have been all over the episode and all over Metafilter if the Mythbuster's plane hadn't taken off as if it proved something; even if hypothetical minor or major tweaks to the setup or plane would have resulted in the plane taking off.

To sum up: Given their methodology a positive result is a-OK, great even; a negative result is mostly useless as data.

CHoldredge,

Brightness is equivalent to the sum of photons converging on a sensor. A lens should indeed be increasing the sum of photons hitting the ant -- though not the energy per photon.

Or am I missing something?

I understand why some are resistant to the idea that Mythbusters is "science", but frankly the concept and application of the show, while containing quite a bit of entertainment, is a decent basic application of science, especially since it is aimed at America which has a distressing amount of anti-science elements.

And, in all honesty I can't help but like that the President is going to be on the show. I think I would say that no matter the party affiliation of the president but frankly this is something GWB, McCain or Reagan would never do, Bush the Ist maaaaaaybe.

Seriously, nobody thinks Mythbusters is pure science. In fact I'd go so far to say that it's only about 1% science, but the fact is it does attempt to test hypotheses using repeatable, controlled real-world circumstances and that makes it way more scientific than the 700 Club or Fox and Friends the vast majority of news segments that discuss "science" in any sort of serious way.

Complaining that Mythbusters isn't scientific(ly rigorous) in their testing methods takes away from the fact that it's one of the few engaging sciencey shows on TV now. The show isn't called Testing Myths with Repeatable Experiments. And the fact that they'll re-test myths if people throw out reasonable alternative testing methods gives them bonus points in my book. Sure, it's "easy programming" to re-tread old myths, but it shows they also take it seriously. Plus, they blow up stuff.

Effugas, not at all, but from that point of view, there is a limit on how closely you can arrange those photons. If I focus my concentrating reflector on a blank wall, it will project an image of the sun. Beyond a certain point, all I can do to make that image smaller (and therefore brighter) is to move closer to the wall. As I move further back, the smallest projection I can create gets larger and larger, until eventually it's much, much larger than the wall and most of those photons are wasted.

For a couple of ancient technology Mythbuster shows, I would totally get cable.

They do, occasionally. One of my favorite segments was when Kari, Grant, and Tori successfully recreated a medieval Korean Hwacha.

Too bad throwing atlatls, breaking pots, burning wattle-and-daub houses, and butchering and transporting large mammals are probably not the most interesting to a TV audience.

Don't forget to burninate all the peoples.

Since the lens is fairly small, but quite close, that means it fills up a lot of square degrees, and the poor ant has no chance.

This rings false. The magnifying glass is only close to the ant because it is designed for reading, therefore has a very short focal length. Take a lens of the same diameter, with a focal point 2 yards away instead of 6 inches, and it will still concentrate the same surface area of sunlight into the same smaller area, thus producing the same watts per square meter, but from much further away, and taking up very little of the ant's field of view.

Are you arguing that the shorter focal distance lens is inherently vastly more efficient at producing a smaller spot?

I suspect your optical principles are talking about brightness, whereas burning is talking about energy (watts). They are not the same thing.

Binoculars and telescopic sights aid night vision because they do make the image brighter. That's why the diameter of the objective lens is the second half of their spec, after magnification.

posted by brenton at 12:00 AM on October 20, 2010


CHoldredge--

A lens takes photons that otherwise would have missed me (in their forward path) and causes them to hit me. The photons that would have hit me, still do (minus a bit of loss, going through the glass and all). But now I have this huge other area of space where photons are pointing at me instead.

Perhaps this is the equivalent of saying, now I have a thousand spotlights on me, instead of one, but no one spotlight is any brighter. However, I've got a thousand spotlights on me. I am, quite indeed, brighter. So much brighter, I am (alas) erupting in flames.

Correct?
