Welcome to Tech Stuff, a production from IHeart Radio.

Hey there and welcome to Tech Stuff.

I'm your host, Jonathan Strickland.

I'm an executive producer with IHeart Radio and How the Tech Are You?

We have an episode that originally published on July 1st, 2020.

It's called It's All Relative.

And when I was a kid, I was convinced that Einstein's theories were the super complicated explanations of the universe that

really had no real intersection with my daily life.

But as it turns out, without an understanding of relativity, a lot of the technology we

rely upon wouldn't work properly.

And it's fascinating stuff.

Hope you enjoy. And it's fascinating stuff. Hope you enjoy.

The Hertz unit refers to the number of repeated phenomena over the course of a second.

So imagine that you're dribbling a basketball so that the ball goes from your hand to the ground, back up to your hand, once per

second. Well, you could describe your dribbling as being one hertz in frequency, one full

cycle per second, up, down, up. Now, if you dribbled twice as fast so that the ball went up,

down, up two full times per second, then it would be two

hertz. Well, we can describe lots of stuff where the unit hurts. We use it to describe sounds,

in which case we're talking about the frequency at which stuff vibrates. Typical human hearing

spans a range of frequencies that at the low end is at 20

hertz. That represents the lowest pitches of sounds. You can think of those deep bass notes,
