I just wish people would stop calling it a damn equation, because it clearly isn't. It's the Drake Estimate.

But that ship has clearly sailed.

It's an equation. The individual components of the equation are speculative, and their values are estimates.

There's unwritten fudge factors everywhere. That's not how equations work. But it is how estimates work.

There's zero shame in calling a thing what it really is.

The fact that it's hard to know the inputs accurately and precisely doesn't make this any less of an equation. Given some inputs on one side, you get an output on the other. You might as well call y = mx + b an estimate.

Well there's math, and then there's physics math. Physics math is different. All the world is a frictionless plane, and we are merely spheres of uniform mass and charge density upon it.

You should see some of the calculus acrobatics they do in plasma physics. It's absolutely bonkers.

I'm sure he's much more known for this than for SETI contributions.

FWIW, I hadn't heard about Frank Drake before, nor of "Drake equation", but I do know what SETI is since before.

I had heard of both but hadn’t realized how directly they were connected.
