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 🙂

Third Independent Inquiry into “Climategate” Vindicates the Science

Posted by mattusmaximus on July 14, 2010

As I’ve posted in the past, the so-called “Climategate” which supposedly threw the science behind global warming into doubt seems to have been little more than hot air, an apparent propaganda campaign by climate science deniers to sow confusion on the whole issue.

Well, as I’ve pointed out in previous posts, there have been a series of three (count ’em – THREE) independent investigations into whether or not the scientific data behind the climate science consensus are sound.  The conclusions of the first two investigations (here and here) were clear: there was nothing in the extensive investigation & analysis of the data to show the scientific community’s conclusions on human-influenced global warming to be in doubt.  In short, the science (and related conclusions) are trustworthy.

Now here’s the money shot: the verdict from the third independent investigation is in, and it is consistent with the first two – the climate science data are sound. In a moment of excellent media win, I was quite pleased to see that this news made headlines in a major media outlet over at MSNBC…

An independent report into the leak of hundreds of e-mails from one of the world’s leading climate research centers on Wednesday largely vindicated the scientists involved, saying they acted honestly and that their research was reliable. …

… The panel’s report said the e-mails contained nothing to overturn the case for man-made global warming put forward by the United Nations’ Intergovernmental Panel on Climate Change. “We did not find any evidence of behavior that might undermine the conclusions of the IPCC,” it stated.

This points out to me the power of the scientific endeavor – while some deniers of climate science will still try to make some kind of hay out of these reports (probably by harping upon the less-than-glamorous language & behavior exhibited in the leaked emails, which shows that scientific researchers are, like the rest of us, human – duh), it should be apparent to any objective observer that the science behind the consensus on human-influenced global warming is now vindicated.  Far from attempting to engage in a cover up, the scientists & institutions involved readily submitted to the necessary investigations – as they should when big questions & controversies come up – and I think as a result the science is stronger than before.

But that won’t stop those with an ideological bone to pick with the climate science community – for them, such as with other science deniers (like creationists in regards to their mind-boggling denial of evolution), they will likely downplay or ignore the findings of these independent investigations in an attempt to cloud the science further.  Some may even go so far as to imply a vast conspiracy in a lame attempt to rationalize away the results.

On the plus side, as I said, the results of these investigations should put some spine in the backs of researchers within the climate science community.  In addition, they should carefully heed the lessons of the “Climategate” debacle in order to, in the future, protect themselves from those who would attempt to tear them down.
