The Physics Philes, lesson 116: Relativistic Doppler Shift

I know, I know…I didn’t write anything about physics last week. It hurt me more than it hurt you, I promise. Let’s see. Where did we leave off? Oh yes, Doppler shift. As we found last week, sound waves can be shifted if either the source of the sound or …

The Physics Philes, lesson 115: The Doppler Shift

We’ve been talking, over the last several weeks, about sound and sound waves and how those waves interact with each other. Implicit in those discussions is the assumption that everyone is at rest relative to one another. That’s not always how it works. We know, of course, that we can …

The Physics Philes, lesson 114: We Got da Beats

Remember last week we learned all about wave interference. As I mentioned at the end of that post, we stuck to waves that have the same frequency. But that’s not always how things work out in the real world. Something slightly different happens when we have two waves overlap that …

The Physics Philes, lesson 93: Do the Wave

We’re chugging along in our journey through introductory physics. We’ve made it through a discussion of fluid mechanics. Now it’s time to start learning about mechanical waves. Before we dive in, we need to nail down the basics. A wave is a fairly familiar thing. Most of us have seen …

Spirit Science: Second Opinion

Back in April, I criticized a video series titled ‘Spirit Science’ that defied the nomenclature it had adopted by denying scientific practices and continues to this day trying to convince its viewers that they can manipulate reality through their thoughts through wordplay that bastardizes scientific concepts and squashes them  in …
