Walking Barefoot on Broken Glass – Not Paranormal, Just Physics

Posted by mattusmaximus on March 14, 2010

While at Skepchicamp 2010, one of the woo-busting physics demonstrations I performed was that of walking barefoot on broken glass shards.  Here’s a close up of the action…

This is a standard carnival trick, also used by various New Age gurus to display their supposed mystical, paranormal, or supernatural powers to their gullible followers.  Sorry folks, no woo is required to explain this (pardon the pun) impressive feat.  This is some video shot by a few of my students earlier this year when we were discussing the physics of pressure

It can all be explained with a simple understanding of basic physics: by walking flat-footed on the shards, I spread my body weight evenly over the entire surface area of my feet, which means that I’m touching a large number of glass shards at once. Thus, since my weight is distributed over so many points, the pressure (force per unit area) at any one of those points is so small that it isn’t enough to stab or cut through my skin.

Thus, through a simple application of Occam’s Razor, we can conclude that nothing paranormal is required to explain what’s going on, just good physics!

Deepak Chopra Goes Off the Deep End of the Woo-Pool

Posted by mattusmaximus on January 3, 2010

One of the kings of New Age nonsense, Deepak Chopra, has written a widely read article at the Huffington Post (yet another reason to no longer take HuffPo seriously), and I felt that it deserved a bit of analysis.  The piece, titled Woo Woo Is a Step Ahead of (Bad) Science, is an interesting rant on the part of Chopra about why all things about the modern skeptical movement, “western” science (science is science folks, wherever it’s practiced), and Michael Shermer are off base, wrong, and just plain mean & nasty.  Chopra really seems to have had something stuck in his craw, and I suppose this was his way of getting it out…

There’s plenty of silliness to cover in Chopra’s article, so we might as well get started…
