"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.

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 […]
Modern humans have been around roughly 100,000 years, but until 55 years ago, none of us knew what the far side of our own Moon looked like. That changed in 1959 with the Soviet Union’s Luna 3 robotic probe, the first spaceship to travel around the Moon and return photos to Earth. My latest column […]
On October 11 and 12, I’ll be helping my friends bring SCIENCE to GeekGirlCon. My contribution: making Möbius strips and Klein bottles out of paper! If you couldn’t make it to GeekGirlCon in Seattle, or maybe you came to my station, but you want the instructions on how to do this activity at home? Well, […]
I don’t write about climate change very often, even though it’s the most important issue facing humanity. That’s mainly because it’s not my “beat“: I’m a physics and astronomy writer, and I do best when I write about topics in my areas of expertise. (And after all, there are many good writers focusing on climate […]
Over the last few months, I wrote a three-part series of longer articles on dark matter, covering three different aspects. The third and final installment ran today. Though I could hardly be comprehensive in just three articles, I tried to cover three major aspects of dark matter science: direct-detection experiments, mapping the location of dark […]
