Yeah, I'm sure it was totally made because someone loved lambdas so much. You probably actually believe that lambda actually means "half-life" in physics equations.
Why isn't it just an alpha in the center? That's also used in many equations as a variable. But you'd look like a moron with a plain old "a" in the middle of your screen.
