On April 18th I gave a presentation to the Chicago Skeptics on the topic of what I call Quantum Nonsense. For example, have you ever been talking to a friend who starts going on about how great a movie “What the Bleep?!” was because it proved water has feelings? Or perhaps a family member saw a show where Deepak Chopra explained that they could balance their checkbook and achieve financial security using quantum jumping? Let’s face it, quantum physics is both fascinating and confusing, and many pseudoscientists and charlatans play upon this fascination and confusion to peddle all manner of nonsense to the unwary. In this talk I try to help people learn how to separate quantum fact from fiction.
Download the PowerPoint of the presentation (one with the audio of the talk embedded) below. If you want to be able to flip through the slides, which I recommend since there are many good visuals, I suggest downloading both files and listening to the audio while flipping through the other presentation. Enjoy! :)

Years ago I posted here about how I kill Santa with science, and it goes without saying that doing so can get quite a reaction out of people. Some reactions have been negative, but a surprising number of people have contacted me actually thanking me for killing the Santa myth. In fact, I was recently commissioned to write a formal article on killing Santa with science for TESConnect, an educational magazine and networking organization centered in the UK. I am happy to share with you the full article in all of its colored glory, along with explicit physics calculations, below… Happy Holidays! :)

I posted about a year ago the audio of my talk on how to more effectively communicate with creationists from the 2013 Chicago Skepticamp, and now I’m happy to share with you all the actual video of that talk. For reference, here is a link to an earlier blog post I made on the topic. Enjoy! :)

This recent silliness by “Doctor” Oz came to my attention: apparently, during a recent show he took seriously the notion that women shouldn’t carry cell phones in their bras because it could give them breast cancer. My skeptical colleague Dr. David Gorski at Science-Based Medicine summarizes Oz’s idiocy and fear-mongering here…
… The story aired on December 6 and was entitled Why You Should Keep Your Cell Phone Out of Your Bra. The entire segment, lasting ten minutes or so, is one blatant piece of fear mongering. Even by the usual low standards of a typical Dr. Oz segment, this one was bad. How bad? I’ll give you a taste. Let me start just by asking what you might expect in a segment claiming a link between an environmental exposure of some sort and a specific cancer? You’d expect some actual scientific evidence, wouldn’t you? Some epidemiology, perhaps, showing that women who hold their cell phones in their bras have a higher risk of breast cancer, perhaps with some relative risks that were at least statistically significant. You might expect some scientific evidence suggesting why the proposed mechanism is plausible. You might even expect that there would be convincing (or at least suggestive) evidence that women who put their cell phones in their bras, when they develop breast cancer, develop it more frequently on the side where they stick their cell phone. These would be reasonable things to expect that, even though they wouldn’t be convincing proof, would at least raise concerns.
There was none of that at all. Zero. Nada. Zip. In fact, I was shocked at how evidence-free this whole segment was. Usually Oz at least tries to slather a patina of scientific evidence on his pseudoscience. OK, maybe not usually, but he does at least sometimes try when he’s not doing a story on alternative medicine, “complementary and alternative medicine,” or “integrative medicine,” anyway. Not here. It’s as if Dr. Oz’s producers weren’t even trying for this one. …
If you want a good analysis that thrashes the hell out of Oz’s claims from a medical perspective, definitely read through all of Dr. Gorski’s blog post. Seeing as how I’m not a medical doctor, I won’t rehash his analysis here; but I am a physics professor, so what I can do is go through the basic physics of why it is implausible that cell phones are even physically capable of causing cancer. In fact, I’ve written numerous posts on this topic already…
This first post is probably the most thorough on the fundamental physics of how electromagnetic radiation/waves (also known as light) are generated and propagate; also included is a basic primer on the different kinds of EM waves, the EM spectrum, what role frequency and energy of light play in these issues, and the all important difference between ionizing and non-ionizing radiation. Here’s the upshot: cell phones emit non-ionizing (i.e. non-cancer causing) radiation.
This article about a hysterical politician in Maine points out the implications of allowing basic scientific literacy to be trumped by the kind of psuedoscience and fear-mongering propagated by “Doctor” Oz and his ilk.
Just a more up-to-date article outlining some more research from the Institute of Cancer Epidemiology in Denmark after it looked at more than 350,000 people with mobile phones over an 18-year period. Conclusion: even while looking for supposed long-term negative effects, none were found.

I’ve posted many times before about so-called ghost hunters and ghost hunting, and much of the time it has been in either good fun (by spoofing them) or a bit more serious in challenging them to be more rigorous in their methodology. However, in this post I want to point out the danger(s) involved in ghost hunting; as is so often illustrated on the What’s The Harm? website, when people buy into pseudoscientific and non-critical thinking, it can have profoundly negative effects.
Case in point: recently some moronic ghost hunters in New Orleans decided that in order to get the spirits supposedly inhabiting an old mansion from the 1850s to “come out and play” that they needed to set fire to the place. The result: it completely burned to the ground…
… The mansion, built in the 1850s, had survived through many incarnations, operating as a boarding house, a hotel and even an illegal gambling house. Though the mansion had been shuttered in recent years, its owner, the Arlene and Joseph Meraux Charitable Foundation, had plans to renovate the building. …
… The fire at LeBeau broke out at about 2 a.m. local time Friday, Nov. 21, and the building was almost completely destroyed by the time firefighters arrived. The ghost hunters had been trying to produce a reaction from the spirits they assumed resided there, by doing what TV ghost hunters call “provocation,” essentially making loud noises, yelling taunts at the ghosts and banging on walls. Frustrated that their efforts failed to yield any spirits, the group decided to light a fire. Whether this was intended to smoke the spirits out or simply burn the place down, the resulting flames soon reduced the mansion to ashes and four brick chimneys.
While many ghost hunters engage in harmless (and fruitless) fun, as this case shows, there can be a dark, dangerous side to the pursuit. In the wake of popular ghost-hunting TV shows, police across the country have seen a surge in people being arrested, injured and even killed while looking for ghosts.
In 2006, a woman was critically wounded looking for ghosts in a private house near a cemetery; she and a friend were trespassing, and the house owner mistook them for vandals and shot them. In 2010, a North Carolina man died while ghost hunting with a group of friends, hoping to see the ghost of a train that crashed years earlier. The ghost train did not appear — but a real train came around a bend and killed one man who couldn’t get out of the way in time. … [emphasis added]
Note the backwards thinking here: the ghost hunters in question were so hell-bent on “proving” the existence of the ghosts supposedly haunting this mansion that, when all else failed, they actually burnt the damn place down! It is revealing that the thought that perhaps there were no ghosts/spirits in the place at all seems to have never occurred to them, so strong was their confirmation bias in favor of all evidence pointing towards the existence of the ghosts/spirits…

In honor of the epic 50th anniversary of Doctor Who, I am going to re-post a recent post I made this past summer: SkepchickCON-CONvergence 2013 Day Two – Physics of the TARDIS…
On my second day at SkepchickCON–CONvergence 2013, I participated in two panels. The second panel was titled “The Physics of the TARDIS” and since the con had a “British Invasion” theme to it, Doctor Who was a big hit this year. And that meant that this panel was very well attended, so well attended in fact that it ended up being standing (and sitting) room only! In this panel we got into all manner of questions regarding the physics, realistic and speculative, regarding time travel, the TARDIS being bigger-on-the-inside, and more.
My co-panelists for this discussion were Steve Manfred, Renate Fiora, and Katherine Krantz. Check out the audio of the panel below, and enjoy! :)

One of the things I like to do on Halloween, besides handing out candy to trick-or-treaters, is watch scary and spooky themed movies. I recently re-watched one of the great ones from the 1980s: Ghostbusters. Did you ever notice that the character of Peter Venkman is actually kind of a skeptic? This fact is outlined in the following hilarious scene from the opening of the movie, where Venkman essentially calls out his colleagues for engaging in an argument from ignorance in his typical deadpan way as they search for a ghost…
**Dialogue from 0:19 – 0:38**
Ray Stantz: “Look!”
Egon Spengler: “This is hot, Ray.”
Ray: “Symmetrical book stacking, just like the Philadelphia mass turbulence of 1947.”
Peter Venkman: “You’re right, no human being would stack books like this.”

This past Sunday evening, I was interviewed on The Pink Atheist podcast/radio show. The topics of discussion were the vaccine survey research I was involved with and the importance of promoting a good pro-vaccine message, as well as talking about some of the physics behind various crazy demonstrations I perform both in and out of the classroom.
Click the link below for the full audio of my interview, which starts at the 20:25 mark. Enjoy! :)
