"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.

Well, my upcoming class is unlikely to cover everything. After all, there’s a lot we still don’t know about cosmic inflation, including whether it actually happened or not. According to some theories, the Universe expanded very rapidly right after the Big Bang, which would explain a lot of the odder features of the cosmos as […]
Predicting the future, especially of something subject to the winds of political misfortune as space exploration, is problematic. However, it’s a safe bet it won’t look like it did during the first few decades. More nations than ever are interested in sending spacecraft into orbit and beyond (including crewed spaceships), and privately-owned companies are taking […]
Of all the articles I’ve written over the last four years, none elicited stronger responses than “The Problem of Richard Feynman”. While many people responded positively, I was also lambasted by a conservative blogger, accused of trying to boost sales of my nonexistent book or otherwise make money on an unpaid blog, and generally told […]
Saturn’s small moon Mimas is best known for the giant crater Herschel, which makes it look like the Death Star. However, a new study based on Cassini data shows that its interior is weird too. While Mimas presents the same face to Saturn due to tidal-locking (just like the Moon does with Earth), it rocks […]
One of the biggest science stories of 2014 came out of the BICEP2 cosmic microwave background polarization experiment. Last spring, the BICEP2 researchers announced they had measured something known as B-mode or tensor-mode polarization, a particular twisting of light that is the hallmark of primordial gravitational waves. Those waves in turn would be a strong […]
