Skeptical Panels & Discussions at Chi-Fi Con

Posted by mattusmaximus on April 11, 2015

At Chi-Fi 2015 in Chicago this past March, the Skepchicks ran a track on issues related to skepticism, critical thinking, and science (and, I might add, ours was one of the more well-attended tracks 🙂 ). I was honored to participate in a number of these panel discussions, and I recorded the audio of them all to share with you here. To access the audio files, simply open up the PowerPoint linked below; each panel recording is on its own page.

Chi-Fi 2015 SkepchickCON Track

Chi-Fi Bigfoot 2

One of our panels at Chi-Fi’s SkepchickCON. I’m making a cameo appearance as Bigfoot 🙂

For reference, the panels in which I participated were:

Ask A Scientist: Ever wonder how black holes work? Want to know why we get brainfeeze? Do you really know why the sky is blue? We have you covered from asteroids to zoology as our panel of science experts answer your burning questions.

Star Trek, the Skeptical Paradox: Boldly go where no SkepTrekker has gone before as we discuss the unusual, yet amiable marriage between secular humanism, religion and spirituality within the Trekverse.

Science of Stargate: Black holes, wormholes, naquadah, and symbiotes. It’s fantastic science fiction, but how do the stories of Stargate fit in with real science? Find out!

Science of the Apocalypse: This is the way the world ends! Or is it? We’ll explore some of our favorite ways the “end of the world as we know it” might happen and the science behind these fantastic scenarios.

Science vs. the Humanities: Some people think that science and the humanities are destined to be in conflict. From postmodernist nonsense to looking at science as “the only way to know anything about the world,” there are many times when the two fields of study appear to be at odds. But does it have to be that way, and how can they get along? Come to this panel to hear a variety of perspectives on this question.

Help Bring Reading Rainbow Back!

Posted by mattusmaximus on May 29, 2014

This isn’t necessarily a skeptical blog post, but it is an educational one in that in order for people to be skeptical and critical thinkers they must be able to share, disseminate, and critique ideas… and that means being able to read.  Thus, this blog is proud to support the new Kickstarter effort to bring back Reading Rainbow! 😀

Please watch the video and consider donating to this worthy cause…

“Mysterious Planet-Sized Object” Is… A Planet!

Posted by mattusmaximus on December 9, 2011

A couple of days ago I came across this article titled “Mysterious planet-sized object spotted near Mercury” and it contained some shocking images.  I reproduce some of these images and related commentary from the article below…

The mystery image of a “cloaked alien ship”… the Romulans, perhaps?

… Theorists have seized on the images captured from the “coronal mass ejection” (CME) last week as suggestive of alien life hanging out in our own cosmic backyard. Specifically, the solar flare washing over Mercury appears to hit another object of comparable size. “It’s cylindrical on either side and has a shape in the middle. It definitely looks like a ship to me, and very obviously, it’s cloaked,” YouTube-user siniXster said in his video commentary on the footage, which has generated hundreds of thousands of views this week. Now, how this user was able to determine that the object was “obviously” a cloaked spaceship with no other natural explanation remains as much a mystery as the object itself. …

Note the staggering level of argumentation from ignorance here.  I like to call this sort of reasoning (if you can call it that) from various UFOologists the “alien-of-the-gaps”, because much like the related “god-of-the-gaps” argument from ignorance, what they do is find some kind of strange image and/or phenomenon for which they do not have en explanation and then they immediately give it an explanation unsupported by evidence.  In short, because they don’t know what it is, they know it’s aliens!  Huh?!

This, of course, is a direct contradiction and points out just how ludicrous the general argument from ignorance can be.  If the object is an Unidentified Flying Object (UFO), then by definition it is unidentified – which means that you admit right off the bat that you don’t know what it is!  So if you don’t know what it is then how can you suddenly turn around and, seemingly without any kind of scientifically-valid or evidence-based reasoning, state that it is an alien spacecraft?  Using such loose argumentation, I could just as easily claim the object in question is Santa Claus (but no, that would be silly).

Of course, a little more research shows that astronomers actually have figured out what this “mysterious planet-sized object” is hanging around next to the planet Mercury.  It seems the answer is that the object is… the planet Mercury itself.  Here’s a fuller explanation from the article…

Of course, there’s another scientifically sanctioned explanation for the curious images, though we’re not certain that skeptics and UFO enthusiasts such as SiniXster will endorse it. Natalie Wolchover of Life’s Little Mysteries put the question to scientists in the solar physics branch at the United States Naval Research Laboratory (NRL). They’re the people who analyze data from the Heliospheric Imager-1 (HI-1)–better known in this context as the camera that shot the footage in question.

Head NRL group scientist Russ Howard and lead ground systems engineer Nathan Rich say the mysterious object is in fact Mercury itself. And what we’re seeing in the footage is the equivalent of Mercury’s wake, “where the planet was on the previous day,” as it travels through the solar system on its natural gravitational path:

To make the relatively faint glow of a coronal mass ejection stand out against the bright glare of space—caused by interplanetary dust and the stellar/galactic background—the NRL scientists must remove as much background light as possible. They explained that they determine what light is background light, and thus can be subtracted out, by calculating the average amount of light that entered each camera pixel on the day of the CME event and on the previous day. Light appearing in the pixels on both days is considered to be background light and is removed from the footage of the CME. The remaining light is then enhanced.

So there you have it.  The object in question is basically an artifact that results from the combination of taking multiple images of that region in space over multiple days, the planet Mercury moving in that time, and processing the light in the image to enhance the coronal mass ejection to make it more visible.

What stuns me about situations like these is just how quickly so many people are willing to invoke magical thinking and jump to conclusions (the “cloaked alien ship” explanation) in the absence of any real evidence.  What is it about openly and honestly admitting that sometimes the most truthful answer is simply “we don’t know” that disturbs so many people?  That, to me, is the real mystery.

William Shatner Sets Phasers for “Debunk” and PWNs John Edward

Posted by mattusmaximus on January 16, 2010

During my random Friday-night web surfing, I stumbled across this little gem that I had to share.  William Shatner (who played Captain Kirk on Star Trek) is interviewing psychic charlatan John Edward on his show “Shatner’s Raw Nerve” and definitely had his phasers set for “debunk”.  Check these clips out! 😀

“Is it possible you’re psychotic, not psychic?”

“John, it’s woo woo.”

Mr. Shatner, this one’s for you!!!

Skepticism & Science at Dragon*Con 2009

Posted by mattusmaximus on September 7, 2009

Well, I’m starting to wind down here at Dragon*Con in Atlanta, which I have basically concluded is Mardi Gras for geeks – a lot of people dress up & party, and I was no exception.  Below was my small contribution to the party atmosphere 🙂

pirate-matt

On a serious note, while Dragon*Con is essentially a big science-fiction convention & general geek-fest, there is a very serious science & skeptical presence here.  The Skeptics track is now in its second year, and it seems as if it grew out of a desire to counter or provide a rebuttal to some of the more woo-ish paranormal nonsense that you see here.  For instance, there is a track which seems quite heavy on the paranormal woo called the X-track where all manner of ghost hunters do their thing.  With so many people attending Dragon*Con who can actually distinguish fact from fiction, it’s no wonder that many people are interested in the actual science & skepticism tracks.

I will outline all the things I did here – lecturing on the Large Hadron Collider & particle physics, participating on the Science of Star Wars panel, moderating the Darwin’s Bulldogs panel on teachers combating creationism, and participating on the Skepticism in the Classroom panel – in future posts.  What I want to discuss for the rest of this post is why it is that I think having skeptics present at events like Dragon*Con is important in the first place…
