Recently was asked to make a presentation on some math involved in a movie. I chose the Men In Black. The scene I selected was the part where the 2 are in the Queens tunnel and they go on the ceiling of the tunnel and continue to go at an unusual high speed on the ceiling and eventually get down and out. I would just like some insight on what kind of math I should present and how to present it. Also some basic "if it were" kind of questions. Thanks for any help.
