Looking back on this week, I had a post about astronomy with a wide-angle lens and about the Tunguska blast. For this weekend’s music, I’m going to rob South Park and show you South Park Elementary’s #1 TV show of all time: And for your weekend amusement, I’ll refer you back to my story on…

Wide-Angle Lenses and Astronomy

Just a short while ago, I showed you how the most powerful telescopes were able to gather incredible amounts of light from a tiny part of the sky, and peer deeper into the darkest regions of the Universe than ever before. But there’s another way to do astronomy that’s just as majestic: view the entire…

Tunguska: 101 Years and 1 Idiot Later

One of the scariest things that could happen to Earth is to be bombarded with an asteroid or comet, as the potential for damage is incredible. Well, it turns out that we get hit by tiny “space pebbles” all the time. Every time you see a shooting star, like the one below, it’s actually a…

Building your own Star

There are very few sources of truly clean energy out there. Coal, oil, natural gas, etc. all expel tremendous amounts of carbon dioxide into the atmosphere, something we know we need to stop doing very soon if we want our planet to be habitable to humans for very much longer. Biofuels, while not as harmful…

Weekend Diversion: Web vs. Image Test!

One of the great things that comes along with warm weather is outdoor concerts! Click “play” below to hear one of the greatest live performances of All Along The Watchtower ever recorded. Any idea who that is, rocking out on the guitar? Sounds a bit like Carlos Santana, doesn’t it? Sounds talented like Hendrix, but…

Remember them this Memorial Day!

It’s Memorial Day weekend, and I won’t be blogging over it, as I’m going to be enjoying my long weekend! (And I hope you are, too.) But I’d like to leave you with some reflections on our history of Space Exploration in this country. (This was originally posted last year.) There are wonderful things going…

A Guide to Teaching Evaluations

Regardless of where you work, one of the most nerve-wracking experiences can be your performance evaluations. Why is this nerve-wracking? Because no matter how talented and capable you are, and regardless of how good of a job you actually do, there are factors that you have absolutely no control over that can affect your evaluations.…

The Physics of Hot Pockets!

When I was a teenager, my choice of food was basically determined by three criteria: It needed to be ready in under 10 minutes. It needed to have enough calories to make me not hungry anymore. And it needed to be (marginally) edible. That was really it. And so it won’t surprise you to know…

A Missing Link Found!

One of the greatest challenges in all of evolutionary science is to figure out which species evolved into which over time. From our perspective, we would love to know how humans came to be, who our ancestors were, and what simpler animals gave rise to us. Well, we don’t know this right now. We know…
