The Sound of Science - "Hemholtz Resonators"

Jun 22, 2018

With me today I have a Hemholtz resonator. This is an incredibly complex instrument, so I’ll do my best to describe it. It’s a glass bottle with a long neck, and I got 6 for about 10 bucks. Okay, it’s a beer bottle, but it is in fact a Hemholtz resonator.”

The Sound of Science - "Resonance"

Jun 22, 2018

What do kids on a swing, musical instruments, and microwave ovens have in common? They all use an underlying scientific concept called resonance as well as being common parts of our daily lives.

With me are two tuning forks, each tuned to 256 Hz. I’m going to strike one and only one tuning fork. After a second or two I’ll put my hand on that tuning fork to stop it. I’m not going to touch the second fork at all. Listen closely.

The Science Of Cicada Songs

It’s that time of year again: when cicada songs flood our warm summer nights, announcing their presence as they attract mates. As a kid I was told they only came out every 7 years. I was confused because I heard them every year. It turns out whomever told me they emerge every 7 years was wrong on two counts: some species of cicadas emerge every year, and some emerge every 13 or 17 years.

The Science of Gut Rumbles

Whoo, that was embarrassing. I accidentally let my borborygmi go. Of course, borborygmi is involuntary, I can’t help it. Borborygmi, the rumbling sound of your gut, doesn’t come from your stomach, nor is it solely because you’re hungry.

WNIJ and NIU STEAM are partnering to create “The Sound of Science,” a weekly series explaining important science, technology, engineering and math concepts using sound. The feature will air at 1:04 p.m. Fridays as a lead-in to Science Friday. The first “Sound of Science” episode airs today.

“STEM is a topic of great interest to our audience – especially with Science Friday listeners," WNIJ General Manager Staci Hoste explained, "so it makes sense to add NIU STEM experts to the mix of information our listeners get during this very popular national program.”
