"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.

A lot of science fiction plot devices are devoted to getting around the speed of light. In the real Universe, nothing with mass can travel faster than light, which means we can’t travel to distant stars without taking decades, centuries, or longer in transit. So, sci-fi draws from teleportation, hyperdrive, warp drive, and the ultimate […]

For more on these two offerings, please click on the links or scroll down. And please help spread the […]
One of the unfortunate side effects of being a professional science writer is that people send me their big ideas about how to solve major problems in physics. These are usually very poorly constructed; many don’t have any equations at all, and therefore have no way to make predictions that can be compared with experiment […]
