Yesterday’s Google doodle got science people fired up.
I got the periodic/wave/Hertz thing. But I tried to see “Google” in it and failed. So I tuned out, feeling annoyed.
Then Frank Noschese, high school physics (etc.) teacher and all around smart person stepped in:
Is anyone else upset that the Hertz Google doodle isn't actually sinusoidal in shape?—

Conversation ensued. Basically, Chris Lusto (high school math teacher and all around smart person) and Frank went back and forth on what exactly constitutes a sinusoidal curve.
Now I was interested. Lusto’s question prompted me to respond:

And then this question got inside my head. Is it still sinusoidal if it’s composed of an infinite series of sinusoids?
I didn’t care even a little bit what the formal definition would be. I was struggling with the spirit of things. Does it make sense to call this thing sinusoidal?
And then walking to the parking lot at 9:00 at night, it struck me.
