"Galileo's Pendulum" is a blog covering physics, astronomy, math, and related topics - all for a non-specialist audience. I am especially interested in showing how science actually works, and how the various conceptual pieces fit together to make the theoretical framework that provides the best description of the natural world.

Methane on Mars is a huge deal, so much so that every announcement finding evidence for it in probe or telescope data gets a big media hoopla. That’s because methane is a common byproduct of life as we know it, though some non-biological processes make it too. (We’re pretty certain, for example, that the methane […]
As I’ve mentioned on several occasions, I’m director of CosmoAcademy: the branch of the CosmoQuest public outreach/citizen science organization that runs online classes. We’ve had a good year, offering a variety of classes on many topics. Now we’re looking ahead to 2015 and the sorts of things we want to offer in the new year. […]
Comets are an obvious culprit if you want to understand how water gets from one part of the Solar System to another. They’re famously known as “dirty snowballs”, for their mixture of water ice, ices made of other molecules, and a few organic molecules thrown in to give them a dark gray color. Since very […]
On Friday, NASA performed its latest test of the Orion capsule, the next-generation spaceship that will carry human crews. Since the long-overdue retirement of the Space Shuttle, the United States space program has relied on Russia to get astronauts into orbit. But Orion is more than a Space Shuttle replacement: it’s intended to travel beyond […]
Last week (November 21, 2014, to be specific), I spoke to the astronomy department at New Mexico State University about science communication. Necessarily my talk was my personal perspective: I’m definitely no expert on the topic. However, I like to think that I’ve learned a few things during my transition from Kid Who Loved Planets […]
