EVP Patrol Squad: When Parody is Indistinguishable from Woo

Posted by mattusmaximus on November 3, 2012

I just ran across this parody of the “History” Channel by some folks calling themselves the EVP Patrol Squad.  They are spoofing the various pseudoscientific “experts” that are regularly paraded out on that channel in favor of various ancient alien, paranormal, and ghostly claims.  The funny thing is that if you actually watch some of the stuff on the History Channel, it is so goofy that it almost seems that this is straight from one of their shows – so this is good evidence of Poe’s Law.  Enjoy! 🙂

I don’t know about you all, but I don’t think that I’ll ever be able to look a sporks the same again.  The horror… THE HORROR!!!

Solving the Mystery Behind “Mystery Houses”

Posted by mattusmaximus on October 28, 2012

Years ago I performed an impromptu investigation of the Montana Vortex, a roadside attraction whose proprieters claim that there is actually some kind of weird adjustment to the laws of physics in order to account for the strange goings on there.  Like many such attractions, the folks who run the Montana Vortex have a “mystery house” where the effect of gravity seems to be lop-sided.  But while this is obviously an illusion, it certainly feels real…

Thanks to a follower of this blog (@denatureSD on Twitter), I saw this recent Science Friday video from YouTube which nicely explains this phenomenon.  Enjoy! 🙂

EBay Bans Witchcraft and “Supernatural Sales”?

Posted by mattusmaximus on August 16, 2012

Okay, sometimes you run across a story so outlandish that it just seems too goofy to be true, kind of like those headlines you see in The Onion… then you find out they ARE true and you get whiplash from the double-take.  Case in point, this little gem from the LA Times:

EBay bans supernatural sales of magic spells, potions, hexes

By Tiffany Hsu This post has been updated. See note below.August 16, 2012, 10:58 a.m.
Making a profit on the occult arts? Cultivating a loyal customer base for potions, magic spells and psychic readings? Not on EBay, you’re not.

In its 2012 Fall Seller Update, the online marketplace said it was banning all sales of supernatural goods and services, exiling its witchy and wizardly clientele to the wilds of Craigslist and other Web-based Diagon Alleys.

Among the prohibited items: “advice; spells; curses; hexing; conjuring; magic services; prayers; blessings; Psychic, Tarot, Reiki, and other metaphysical readings & services; magic potions; healing sessions.”

EBay representatives did not immediately respond to questions as to why Harry Potter wannabes were no longer welcome or whether they contributed substantially to EBay transactions.

[Updated, 12:00 p.m. Aug. 16: EBay said in an email that it regularly reviews categories and updates policies based on customer feedback and was “discontinuing a small number of categories within the larger Metaphysical subcategory.”

Spokeswoman Johnna Hoff said that buyers and sellers have complained to EBay that such transactions “often result in issues that can be difficult to resolve.”

“It’s important to note that items that have a tangible value for the item itself and may also be used in metaphysical rites and practices (ie  jewelry, crystals, incense, candles, and books) are allowed in most cases,” Hoff wrote.”]

Beginning Aug. 30, attempts to list such enchantments for sale will be blocked, according to the website. …

Oh dear evil Jebus… you’ve got to be kidding me.  Not “you’ve got to be kidding me” in the sense of “you’ve got to be kidding me that EBay banned witchcraft” but “you’ve got to be kidding me that they even sold witchcraft in the first frakkin’ place!!!”

Don’t get me wrong, I’m glad that EBay woke up and smelled the coffee, so to speak.  But why did they even sell this crap in the first place???

I would also just like to note that, despite showing a semblance of sanity and relation to reality by banning these so-called “supernatural sales”, EBay will still have a subcategory titled “Metaphysical” after August 30.  The mere fact that such a subcategory even exists on EBay just makes me cringe and forces me to seriously question the ethics of those who operate the company.  Selling such nonsense purely for the sake of making a buck just strikes me as wrong; or will the operators of EBay be willing to take “metaphysical money” in place of the real, materialistic cash for these purchases?

Ah well, EBay, this one’s for you:

The Skeptical Teacher to be Interviewed on Darkness Radio – LIVE!

Posted by mattusmaximus on May 14, 2012

I know I’m posting this a little late, but I wanted to let you all know that I’m going to be interviewed tonight (Monday, May 14th) live on Darkness Radio at 11:00pm CDT.  If you recall, I blogged some time ago – almost two years – about a very interesting discussion I had with paranormal investigator Dave Schrader at Convergence 2010 on the topic of “ghost hunting”.  Despite the fact that Dave’s a believer in ghosts and the paranormal and I’m a skeptic, we hit it off and he invited me to be on his show so that I could give my perspective as a skeptic… well, it took awhile, but tonight’s the night! 🙂

If you can catch the show, please click the Darkness Radio icon below to listen live.  Otherwise, try looking it up on the Darkness Radio archive afterwards.

2012 Pigasus Awards are Here!

Posted by mattusmaximus on April 1, 2012

As is the skeptical tradition, every April Fool’s Day the James Randi Educational Foundation releases its annual Pigasus awards (so named for the notion that certain crazy ideas are to be believed “when pigs fly”).  Below is James Randi himself announcing this year’s winners… or are they losers? 😉

An Honest Liar – The Story of James “The Amazing One” Randi

Posted by mattusmaximus on February 18, 2012

One of my biggest skeptical heroes is James Randi.  He is a small man with a big laugh, an even bigger heart, and an even bigger love for the pursuit of skeptical analysis into all manner of paranormal, mystical, or odd-ball claims.  For Randi, no questions are off limits and skepticism knows no bounds; he and his legacy are one of the primary reasons why I am here, doing what I do on this blog and in my daily life as a skeptic and teacher, and I know his work (through the James Randi Educational Foundation) has reached and inspired countless others.  Now there is a movie being made about him, called “An Honest Liar: The Amazing Randi Story”.

Watch the trailer, pass it on to your friends (even if they aren’t card-carrying skeptics), and consider helping to get this film made.  As is stated early in the trailer, “This is a film about trickery, fraud, about lies…” 🙂

Physics Proves the Existence of Ghosts?

Posted by mattusmaximus on November 24, 2011

I’ve blogged here before about “professional” ghost-hunters and their woo.  And in many cases I have taken such “professionals” to task for not really following any kind of decent, consistent protocols (such as knowing how their instrumentation works, duh) but instead favoring stories that seem to be a combination of the Blair-Witch Project and various kinds of techno-babble.  But now I just have to mention a couple of things about how many ghost-hunters just seem to get basic physics (pardon the pun) dead wrong.

My skeptical colleague Ben Radford recently wrote an article for LiveScience.com on this very point…

Do Einstein’s Laws Prove Ghosts Exist?

… Despite years of efforts by ghost hunters on TV and in real life, we still do not have good proof that ghosts are real. Many ghost hunters believe that strong support for the existence of ghosts can be found in modern physics. Specifically, that Albert Einstein, one of the greatest scientific minds of all time, offered a scientific basis for the reality of ghosts. …

Now hold on a minute.  As we’ve seen before, it is not uncommon for pseudoscientists and cranks of all kinds to try glomming onto Einstein’s coat-tails as one of the most well-known and respected scientists of the 20th century as a way of trying to gain traction for their ideas.  It is as if they think that by simply invoking Einstein’s name and theories, despite the fact that they have no real understanding of those theories, that it will somehow, magically make them correct.  Of course, this simply displays a fundamental flaw in the thinking of ghost-hunters, because it shows they have no real knowledge of how science (much less physics) works.

Specifically, in this case the ghost-hunters are claiming that Einstein’s theory of relativity “proves” the existence of ghosts:

… For example, ghost researcher John Kachuba, in his book “Ghosthunters” (2007, New Page Books), writes, “Einstein proved that all the energy of the universe is constant and that it can neither be created nor destroyed. … So what happens to that energy when we die? If it cannot be destroyed, it must then, according to Dr. Einstein, be transformed into another form of energy. What is that new energy? … Could we call that new creation a ghost?”

This idea shows up — and is presented as evidence for ghosts — on virtually all ghost-themed websites as well. For example, a group called Tri County Paranormal states, “Albert Einstein said that energy cannot be created or destroyed, it can only change from one form to another. When we are alive, we have electrical energy in our bodies. … What happens to the electricity that was in our body, causing our heart to beat and making our breathing possible? There is no easy answer to that.” … [emphasis added]

Actually, the answer is pretty easy, as long as you understand how energy is related to matter as outlined in Einstein’s theory.  It can all be summed up in what is probably the most well-known, but one of the least understood, equations in all of science… Read the rest of this entry »

Halloween: The Perfect Opportunity to Promote Skepticism!

Posted by mattusmaximus on October 27, 2011

My favorite time of the year is almost upon us: Halloween! 😀

I love Halloween not just because of the candy, the costumes, and the decorations (when else can you be a complete freak and it be socially acceptable?) but also because of the wonderful potential for promoting skepticism and critical thinking about various paranormal claims.  Let’s face it: at this time of the year, ghosts, witchcraft, psychics, and various other kinds of woo are on everyone’s minds, so why not take advantage of that fact and use it to inject the skeptical viewpoint on things?  I have found this to be a very effective teaching technique over the years, so that’s why I pass it along to you.

So in the spirit of the season (pardon the pun), allow me to share with you some links to various Halloween-ish skeptical resources that you can use, including a few of my earlier blog posts on the subject…

“The Skeptic’s Dictionary” Now Available on iTunes!

Posted by mattusmaximus on August 23, 2011

Whoo-hoo!  I’ve been waiting for a long time for this: the famous Skeptic’s Dictionary – that amazing online resource on all things paranormal, pseudoscientific, and full-of-woo – has come to the iTunes store (actually, it came to iTunes earlier this year, I’m just a little behind).  This means that you can download it to your mobile smart phone and have the entire resources of the Dictionary available at your fingertips for when someone with whom you are speaking makes a less-than-skeptical claim 🙂

It’s not free, but in my opinion for $0.99 it is quite a bargain.  Check it out…

Firewalking is Just Physics, Not Mysticism

Posted by mattusmaximus on July 28, 2011

Fire is cool… well, not cool, because it’s actually pretty damned hot.  But what I mean is fire is really interesting to watch – what kid hasn’t at some point been fascinated simply staring into the depths of a campfire?  Do you know what’s more interesting?… the fact that some people actually like to walk on fire.  This in and of itself is just all-around awesome, but then some woo-meisters have to go and spoil it with a bunch of made-up New Age nonsense.  The purpose of this blog post is to show you why firewalking really works.

My skeptical physics colleague David Willey shows his stuff, sacrificing himself for science.  **THIS IS EXTREMELY DANGEROUS AND SHOULD NOT BE PERFORMED WITHOUT PROPER SUPERVISION**

And just to show you that I put my money where my mouth is, below is a video shot of me and my colleagues performing an experimental firewalk back in the summer of 1999…

We decided that we wanted to study the physics of firewalking for ourselves and made this video as a way of documenting the effect. There are (were) two basic competing, scientifically plausible ideas for why it is that firewalkers are not too damaged by the high temperatures during the walk across hot coals: low thermal conductivity and the Leidenfrost effect.

In the first hypothesis, it is the low thermal conductivity of ash, wooden coals, charcoal, or rocks that the firewalker traverses in their journey. Even though the temperatures are extremely high (on the order of 500-800 degrees Fahrenheit), the low thermal conductivity means the rate at which heat will transfer from the hot material to the walker’s feet is very slow. This is why when you check out a baking cake in the oven it is okay to touch the batter but not the metallic pan – the thermal conductivity of the cake batter is low whereas that of the metal pan is very high!

In the second hypothesis, the Leidenfrost effect protects the walker’s feet. The Leidenfrost effect is the same thing that prevents your finger from being burned when you touch a hot iron with a wet finger. The hot iron turns the spit into steam which forms a temporary insulating layer between the iron and the finger. In this argument, the sweat on the walker’s feet is what is vaporized and then protects the feet from the hot coals.

In the video we tested out these two ideas, and we found the Leidenfrost effect to be inadequate to explain the phenomenon. It is the low thermal conductivity of the coals which prevented our feet from being too damaged – I walked a total of four times, three times dry and once with very wet feet. After three dry walks my feet were fine, with only one very small blister (half the size of a pinky nail, barely visible on the video) on one foot, but during the walk with wet feet, to test out the Leidenfrost effect, I found the coals sticking to my feet… OUCH!!! That is where I got badly burned (which is apparent by the very end of the video).

One thing we found was clear: we successfully negotiated the fire bed without any appeals to New Age mysticism or supernaturalism – no prayers were muttered, no crystals stroked, and we never even bothered to measure our “chi” levels. Such appeals to woo are simply not necessary to explain what is happening here – in fact, I have a challenge: if any New Age firewalking guru wants to really convince me that they have paranormal powers, then they’ll walk barefoot across red hot METAL!

I submit that no one will ever seriously attempt such a stupid feat, and even if they did I guarantee they’ll only do it once 😉

For more information on the physics of firewalking, I suggest reading Dr. David Willey’s page at http://www.pitt.edu/~dwilley/Fire/FireTxt/fire.html
