Tricked ya, kind of. This is a just for fun thread.
I'm on a kick with this today in my mind, though I don't know if anyone is going to want to catch on. Tell a story about a function in combination with something to do with physics or any strange sci-fi/ phenomenon. (Si doms going back in time, etc, can use multiple characters or build on previous posts.)
I would start with some of mine but want to see some others' ideas first.
