Today is pi day (3.14), Albert Einstein's birthday, and talk like a physicist day. I'm a physicist, so I guess I talk like one all the time, but anyway.
Because I have friends who understand what I mean, I have the habit of asking people for their boundary conditions when I want to make plans together with them. And when i didn't know the English word "slide" at the playground, I asked what to call the thing that is like an inclined plane. Some think that's funny.
