High school physics and math as a major. I could scan you my scripts and papers if you're interested.....no won't. ;-D

But maybe "commonly used" was maybe the wrong term. More appropriately: "sometimes" or "by some".

Where in the world? I’ve never used it despite similar background. Perhaps regional?

I have never seen it used as not once in maths or physics. "extremely rarely" perhaps.

To be fair, there are lot of math symbols out there.

There are lots of examples of the lightning bolt in there. In fact, under ulsy Contradiction symbols, there are four variants.

I also noticed the exact symbol being discussed is listed under "Angles".
