MythBuster Developing Light-Weight Vehicle Armor 308

gearystwatcher writes "MythBusters' Jamie Hyneman has been developing blast-resistant, light-weight armor for use on US military vehicles in Iraq and Afghanistan based on his work with show co-host Adam Savage. 'We had a lot of experience in the show dealing with explosives, obviously in ways and situations that are outside the norm. This is very revealing, because when you see something outside the norm you get to see what the boundaries of the phenomenon are,' Hyneman tells The Reg during an interview for the new MythBusters' season."

    These always seem to pop up on any Mythbusters thread. No, they're not scientists. They're not pretending to be scientists. And nope, they don't have time to spend years with a research team adjusting for every variable in every experiment in some carefully controlled lab somewhere.

    What they *are* are very knowledgeable laymen, applying basic scientific methodology to fairly straight-foward questions in an entertaining fashion. They bring the basics of scientific testing to the masses. They teach concepts such as skepticism and empiricism to a population that too often relies on hearsay and superstition in their beliefs about the physical world.

    No, they're not scientists. But that doesn't mean they have nothing to teach or that there is no value in their experiments. As the Wright Brothers and Thomas Edison could probably attest, sometimes even a layman has insight to offer.

          I think it'd be safe to say that the quality of work they produce is often equivalent to what your average scientific team produces *before* it goes through the peer-review process.

          The TV show is not the equivalent of a journal publishing results, but of the team submitting to a journal. The Mythbuster Forums are the closest thing they have to peer-review. They then often "resubmit" to the journal to address the criticisms.

        Adam and James may or may not be scientists, but I think there are "scientists" that are on the production team for the show. I'm a PhD chemist in the field of medicinal chemistry, and we've had TV documentary crews come in and film something about our work before. When they do the filming, they just merely ask us to pipet some random liquid into another container for no reason other than to provide some "science" looking video footage. So in effect, even though we are "real" scientists, when we're on TV, we're just actors, but there's science behind the info being disseminated. I tend to think of the mythbusters in a similar way.
        I understand that even their methods are not up to the standards of science publication, but even we do try out things in the beginning in a way not too dissimilar to the Mythbuster way (ie not statistically significant, using some mock-up equipment, or whatever) before we fully commit to an experiment or before we purchase the proper equipment that would cost $50,000 or something. So yeah, the Mythbuster show is pretty scientific.

      I'd be more inclined to call them engineers. Yes, they do experiments, as that's kinda the point of the show, but if you examine their skill sets and techniques, it's pretty obvious what we'd call them if they applied those skills to another field. They make blueprints, run computer simulations, build small scale prototypes, build large scale tests, etc. In particular the "keep at it til something breaks/blows up" approach is engineer thinking.

      So, they're Hollywood SFX guys putting engineering skills to work testing popular science. The fact they're sneaking lessons about control groups and repeatable results into what is ostensibly an entertainment show is an added bonus. The purists who shout "it's not REAL science" are just setting up a "no true Scotsman" argument, since while "science" has a clear meaning "REAL science" does not.

          If they were 'real scientists', they'd do more research, and more rigorous testing.

            In virtually every experiment I've seen, they're eyeballing where the light is being reflected

            Yes, just as the soldiers in ancient Greece would have done. Part of the criteria of that experiment that they made clear from the get-go was that it had to work in the real world, using materials and resources available to Archimedes, and be executed in a realistic fashion. They've had two follow-up episodes now where they've given critics a chance to prove themselves (including the MIT students who so ardently claimed they could do it) and none have been able to replicate this supposed accomplishment in anything resembling real world conditions.

            People hold on to the Archimedes myth because they WANT to believe it, not because it really happened. That's exactly the kind of quasi-religious belief that REAL scientists are supposed to question, not accept blindly (as so many Mythbusters critics seem to).

      XKCD does a good job summing it up: http://xkcd.com/397/ [xkcd.com].

      While careful controlled tests are important to science and critical to many discoveries, that is not the core of what science is. The core is that ideas are tested by experiment. It is the process of saying "Hmmm, maybe X causes Y, let's try it and find out!"

      That's the basis of what they do, and the basis of science. The higher level of rigor are important as well, but they aren't the main thing. Scientific thinking and action in every day life does not mean doing a laboratory based double blind study of every little thing. You'd never make it to work if you did that for everything. It does mean holding your idea up to scrutiny and testing them out. Mythbusters helps promote that.

      Also as a side note they are often more rigorous than it appears. If you've watched some outtakes/behind the scenes stuff it turns out that they often do more testing than you see on screen. Again that's not to say they do everything grade-A lab proper, but it can be more than it appears.

        The rigor also is only useful for negative results. For positive results, rigor is unnecessary; if you aim to prove that something is possible, and you can make it happen, then it's possible.

        The lead balloon is a good example. The myth was that a lead balloon is an impossibility. They built a working lead balloon. Therefore, lead balloons are possible.

        Now, if they had set out to prove that something is possible, and failed to do so, that does not necessarily mean that it's impossible.

      There is no such thing as "bulletproof glass". Usually, what you have is a combination of two things:

      * a polymer and glass layered sheet
      * of a specific thickness and ply count

      For instance, most 'bulletproof glass' is just rated for pistol calibers (as I believe bank teller glass tends to be). Rifle calibers will punch right through. I think you'll need something close to 6" or so to withstand a shot or two from a 30 caliber, high velocity rifle (eg. think mostly anything from WWII, 7.62 NATO, 7.62R, etc.). A .50 Browning is likely to put a nice 'little' pock in such a plate. I wouldn't stand on the other side voluntarily.

      And, with all frangible materials, with repeated impacts they will start to be less effective at fulfilling their role.

      I believe there's a new polymer/glass/transparent aluminum glass out there, too, but they're all variations on the same theme.

      • Yeah, this is what most people don't realize.

        There is a hell of large difference between different calibers and even different types of ammunition at the same caliber.

        Saying something is bulletproof only means something if you specify against what projectile AND what projectile velocity.

        You can get away with much thinner than 6" for .30 cal, but it's still a fairly thick piece of armor.

        As 'pistol calibers', and the resultant energy, tend to vary wildly - that's pretty much a meaningless statement. But most teller glass tends to be rated for rifles anyway.

      Well, you never know, they might actually stumble upon something valid. In fact, they might have already discovered something, and the press release could be lagging significantly behind the development like it does so often with military developments.

      They have practical experience:
      * blowing stuff up in creative but specific ways using improvised explosive devices, of qualities equal to or exceeding what you'd see in the field
      * instrumenting the entire scenario for data analysis later in such a way that the instrumentation is not destroyed
      * preventing other stuff from getting destroyed by said explosion

      You can spend all day failing to come up with a material with the right properties no matter which angle you attack the problem from. Sure, you could model the physics until your brain leaks out of your ears, and you can also waste inordinate time and materials testing via a "Okay, how about now? Now? Now?" methodology. In the end, you can get similar results by calculation or experiment. Check out Damascus steel, for example - we haven't completely figured that out yet, and we certainly can't reproduce it, but people were making it and you can believe they weren't using modern science to design it. I do believe in the value of science, but it doesn't always need to trump experience.
