I’ve been teaching physics, astronomy, and math at both the high school and college level for about 18 years. And in that time I’ve made a number of contributions to the intersection of skepticism and education. I’m proud to say that one of them is a my part in a new ebook published by the James Randi Educational Foundation, available for free download. Please pass this along to any educator whom you know is interested in preserving and encouraging scientific and critical thinking in the classroom 🙂
The JREF is pleased to offer a new eBook for educators
Magic in the Classroom is a collection of essays by educators across the curriculum who are using extraordinary claims to teach critical thinking. Editor Robert Blaskiewicz gathers the contributions of fourteen authors from the James Randi Educational Foundation’s Swift Blog who write on topics ranging from popular culture, psychology, linguistics, evolution, exobiology, history, folklore, and many more. Together these essays represent the work of a vibrant skeptical culture in education that is bringing critical thinking skills to students across the curriculum.
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! 😀
Well, The Amaz!ng Meeting 9 (the largest skeptical gathering ever!) is about to get underway in Las Vegas! I will try to provide some updates about how things are going at the conference and the general goings on, but I know that I’m only one guy with a limited perspective on things.
So, whether you are attending TAM9 or not, perhaps one of the best things to do to keep up is to read the following excellent post on the Digital Guide to TAM9. The author is Tim Farley, perhaps better known as the creator of the What’s The Harm? website, and this post gives you all the details (and I mean ALL the details) on how to follow what’s happening at TAM9…
The purpose of this post is to be a clearinghouse for all things digital related to the meeting. I’ll show you how to get information you need about the show, how to get connected and stay connected once you are in Las Vegas, and more. I’ll provide links to a variety of resources online that will help.
Please note: in most cases I did not create the resources listed. Most were created or published by the JREF itself, other TAM9 attendees or JREF Forum users. Where possible I’ve also provided links where you can get in touch directly with the content creators. …
According to this story over at Space.com, there is an amateur astronomer claiming that he has discovered what he calls a “Base on Mars” in the following image that he downloaded from Google Mars…
All I can say is… are you kidding me?! A grainy, fuzzy, and heavily pixelated image from Google Mars shows… what exactly? Why couldn’t this be some kind of geological feature on Mars, or couldn’t some of the features be artifacts of the imaging process? Why the rush to jump to “alien base on Mars” without any supporting evidence? This sort of thing is on par with people using similar crappy-quality images to claim they’re looking at Bigfoot, the Loch Ness Monster, or seeing Jesus in the clouds. Folks, it all boils down to that well documented phenomenon called pareidolia, because if there were decent high-resolution images available then it would be harder for people to see what they (consciously or not) want to see in the pictures.
Some more reasonable possibilities are suggested by some experts in the Space.com article:
“It looks like a linear streak artifact produced by a cosmic ray,” said Alfred McEwen, a planetary geologist at the Lunar and Planetary Lab at the University of Arizona and the director of the Planetary Imaging Research Laboratory. McEwen is the principal investigator of the High Resolution Imaging Science Experiment (HiRISE), a powerful telescope currently orbiting Mars.
Cosmic rays are extremely energetic particles emitted by the sun and other stars. For the most part, the Earth’s protective magnetosphere blocks them from hitting the planet’s surface, McEwen explained. “But with space images that are taken outside our magnetosphere, such as those taken by orbiting telescopes, it’s very common to see these cosmic ray hits. You see them on optical images and a lot of the infrared images too,” he told Life’s Little Mysteries. …
… The digital compression software that converts the image into a JPEG file then “sort of smears out the image, giving it that pixelated look,” McEwen said. What started as a clear streak in high-resolution turns into a streak that, in the armchair astronaut’s words, looks like it is “made up of cylinders.”
That, or this guy actually did discover an alien base on Mars. I think you’d have to have a particularly dull Occam’s Razor to accept that conclusion, however.
Okay, I just couldn’t pass this one up… I saw this video today on Yahoo Sports where they claim to show recent footage of the world’s longest basketball shot. I’m a bit skeptical, because such videos have been released to the Internet before and many are found to be digitally altered or tweaked. So it’s tough to take something like this at face value.
But I’m willing to be convinced – most especially because, if true, it’s a pretty damn cool feat! And it does make sense that, given enough attempts, something like this could be done – there is, after all, nothing in the laws of physics which would prevent it. With that, here are two videos showing the claimed shot…
So, my fellow skeptics, what do you think? Real or fake? Let the games begin! 🙂
