The Skeptics Society has retired Skepticblog (while preserving all posts online at their original urls for future reference), but we’re proud to announce our bigger, better new blog: INSIGHT at Skeptic.com! Dedicated to the spirit of curiosity and grounded in scientific skepticism’s useful, investigative tradition of public service, INSIGHT continues and exp […]
Some people say, "Oh, there's anti-science on both sides of the political aisle." But that neglects one important fact: in only ONE political party are the leadership and the party platform dominated by science denial.
Would you believe there is a patch of trapped garbage floating in the North Pacific bigger than the state of Texas? It's called the "Great Pacific Garbage Patch".
While I was at Dragon*Con in Atlanta last month, I did a lot of things. Among them was to be interviewed by my friend and skeptical colleague Ted Meissner, a.k.a. The Secular Buddhist. For a long time, Ted and I have wanted to do a discussion on physics and the martial arts, because we are both skeptics and have a history of martial arts training. And, believe me, if you have been engaged in martial arts training for a considerable amount of time, chances are that you’ve heard some really goofy claims out there. From “no-touch knockouts” to “shielding with chi”, there’s a lot of nonsense being spread around in the martial arts world, and Ted, me, and Brian Gregory (of Virtual Drinking Skeptically) take it all on. Enjoy! 🙂
Matt Lowry the Skeptical Teacher, and Brian Gregory of Virtual Drinking Skeptically join us to talk about the myths and facts of the physics of martial arts.
I remember a television show called “That’s Incredible”, and indeed it was. One particular episode had a self-proclaimed martial arts master, James Hydrick who could — supposedly — move pencils and turn phone book pages with his extra-normal powers. This was debunked with a few flakes of packing material on another show, showing how this charlatan was simply using his breath to cause objects to move.
But there are people who mistakenly believe their own press, who think they really do have supernatural powers, or that they are enhancing their strength with invisible fields of cosmic energy. As you can see in one of the embedded videos on the web page for this episode, one fellow comes drastically close to severing his own arm because of this unfounded delusion. It is important for us to question with confidence, to ask for evidence, or else all claims are equally true, and equally, potentially, harmful.
Matt Lowry
Matt Lowry is a high school physics teacher (plus a part-time physics & astronomy college professor) with a strong interest in promoting science education & critical thinking among his students and the population in general. He is a self-described skeptic, someone who believes in Carl Sagan’s adage that “extraordinary claims require extraordinary evidence.” His blog The Skeptical Teacher is to allow Matt to expound upon various topics related to skepticism, science, and education.
Brian Gregory
Brian Gregory is a software engineer that has recently discovered that most of his assumptions about life are wrong; including beliefs, expectations, roles, etc. This transformation, fueled by the Internet, Social Media, Podcasts, and traditional media, has sparked his passion for science, reason, and the naturalistic worldview. Drinking Skeptically is “an informal social event designed to promote fellowship and networking among skeptics, critical-thinkers, and like-minded individuals”. These “real life” groups meet around the country to provide an opportunity for skeptics and skeptic-friendly people to talk, share ideas (and yes, drink) in a casual, relaxed atmosphere.
In case you didn’t notice the Explicit tag in iTunes on this episode, let me just give you an extra warning here: this is an explicit episode. We’re not talking porn, but there may be a light seasoning of expletives. Also be sure to check out the episode page for this episode on The Secular Buddhist website, as I’ve embedded a lot of the videos we talk about on that page. So, sit back, relax, and have a nice… skeptical drink of you choice!
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 🙂
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.
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…
When I was at The Amazing Meeting 7 in Las Vegas recently, I participated in the first TAM Talent Show. My skit focused upon a favorite physics demonstration and gave me an excellent opportunity to teach some skepticism: the Bed of Nails. Having performed this demonstration about 40-50 times throughout my teaching career, I decided it was time to take things to the big stage 🙂
The demonstration is simple, and dangerous – IT SHOULD NOT BE ATTEMPTED WITHOUT PROPER SUPERVISION!!! In it, I lay down upon a bed of nails, have a second bed of nails placed atop my stomach & chest, have a concrete cinder block placed atop that, and – last but not least – have an assistant break the block with a 10-lb sledgehammer! Here’s some slow motion footage of the demo at the TAM Talent Show…
Moments later, I got up off the bed of nails with no damage at all – pretty impressive stuff! Here’s a photo of my chest seconds after the demo…
The bed of nails has a history of woo – there are some in the martial arts community who claim that their chi or “life force” protects them from injury. Others, such as gurus in India, claim that the only reason they are uninjured is because of the specific type of meditation they perform. But a simple application of Occam’s Razor is all that is necessary to explain what’s going on here – and it doesn’t have anything to do with chi, mysticism, or anything supernatural.
