The Physics Philes, lesson 115: The Doppler Shift

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 hear things eve if they are moving. It would be a pretty weird world if we couldn’t. But that doe... »

Awesome Sauce Music Friday! Cult of Mac Edition

You guys! Did you hear? Apple announced its new products this week. *swoon* I’m fully ready to admit that I’m a bit of an Apple groupie. If I had the disposable income, my apartment would be decked out in Mac. I just can’t get enough of that smooth user interface and App Store! And, even though I’m an analog watch person to the core, that Apple Watch looks awfully pretty. T... »

The Physics Philes, lesson 114: We Got da Beats

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 have slightly different frequencies, and all we have to do is apply some concepts we already know and love. Let&#... »
