Physics of Board Breaking & Karate at The Amazing Meeting 8

Posted by mattusmaximus on July 14, 2010

This past weekend I attended The Amazing Meeting 8 in Las Vegas, along with about 1300 other skeptics & supporters of science.  And, like last year, there was a talent show in which I participated.  Last year I performed the bed of nails demonstration and explained the physics involved, but this year I decided to do the hitting, so I gave another skeptical physics lesson – this time on karate & board breaking.  And, thanks to my colleague Dean over at the Blog of Phyz, I have some slow-motion footage of my grand finale break…

It might surprise many people to know that pretty much anyone can break boards with little training – in order to do more challenging breaks like that pictured here takes more training, though the basic principles are still the same. But in the end there is *nothing* mystical involved – no chi or “life energy” or any of that rot. With proper body mechanics and good use of mass (twisting the body), velocity (dropping to convert GPE into KE), and a low time of impact (solid supports that won’t give) one can make lots of kindling out of boards. Oh yeah, and the spacers are a nice trick as well 🙂 For a fuller explanation, see my previous blog post on the subject.

And, just to put my money where my mouth is, I have to brag about one more thing: while at TAM8, I taught skeptic & paranormal investigator Joe Nickell how to break boards.  Joe had never before performed a board break, and – to my knowledge – has no formal martial arts training, yet I was able to get him successfully breaking boards with just 5 minutes of instruction.  Here he is successfully performing a palm-heel strike on a board I’m holding…

So, there you have it: if Joe Nickell, at his age & with no formal training, can employ the basic physics & body mechanics required to break a board, then pretty much anyone can do it… no special chi or paranormal powers required 🙂

I’m Now a Believer in Chi

Posted by mattusmaximus on March 29, 2010

Well, I don’t know about you, folks, but I’ve been converted from a skeptic to a believer in chi, ki, qi, qi gong, “life force energy”, or whatever you want to call it.  I know that many times I’ve stated publicly on this blog that, whether you’re talking about breaking boards, laying on beds of nails, or walking barefoot on glass shards, such amazing physical feats have absolutely nothing to this chi stuff, but I can do so no longer.  You see, I’ve been convinced by irrefutable & unquestionable evidence that this chi business is the real deal.

So how was I, a die-hard skeptic, convinced of the undeniable reality of chi?  Simple really… I just saw the most amazing video on Youtube!!!

Wow… now I might have to give all that stuff about crystal power a second look, too.

Hat tip to UncaYimmy from the JREF Forum for sharing this little gem of a video with me.  It was so cute I had to pass it along 🙂

Skeptical Teacher Displays Awesomeness at Skepchicamp!

Posted by mattusmaximus on March 9, 2010

Well, I’ve had a couple of days to process all that took place during the first Chicago SkeptiCamp, also known as Skepchicamp. In addition to outlining what I contributed, I’d also like to provide some of the thoughts & feedback from others in attendance…

My presentation, titled Bringing Skepticism into the Physics Classroom, was a display of my belief in “sacrificing myself for science” whereby I perform a variety of extraordinary and dangerous demonstrations in the hopes of dispelling any notions of paranormal woo.  Specifically, I performed three impressive physical feats: walking barefoot on broken glass, breaking five wooden boards with my fist, and laying between two beds of nails while a concrete cinder block is crushed on my chest. Talk about fun times! 🙂

As I told the audience, when I perform these demos for my students I’m not proving that there is no such thing as chi/ki/qi or whatever other New Age “life force” paranormal woo-woo is often invoked to explain these phenomena.  Instead, what I’m encouraging my students to do is simply apply Occam’s Razor to the scenario: their understanding of basic physics is all that is necessary to explain things… no woo required.

For a fuller view of the awesomeness I displayed, check out this great footage shot during my presentation (hat tip to the Bolingbrook Babbler)…

… and here’s another one from a fellow Skepchicamp organizer…

Physics of Karate – No Woo Required

Posted by mattusmaximus on November 14, 2009

I’ve practiced martial arts of various styles for 20 years, and in all that time I’ve heard a number of very strange & woo-filled explanations for why people can accomplish the physical feats they can.  One such example is breaking wooden boards with the bare hands & feet – often people provide an explanation by referencing so-called “chi, ki, or qigong energy”. The whole concept of chi is more of a philosophical concept than anything else, and it is little more than a “dragon-in-the-garage” (an untestable notion that cannot be verified through scientific means).

Well, I’m here to tell you that such physical feats as board breaking can be performed & explained simply by referencing the known laws of physics – no woo required.  Take a look at the video of me performing such a break with five pine boards at once…

How do I accomplish this feat?  Here’s how: I hit the boards really hard – the question is how do I generate such a large force of impact?  Read on…
