Physics hands you gravity, attraction, force, mass and relativity, which is close to an unfair advantage when writing chat-up lines. This is our full run of physics pick up lines, ranked by reader votes. They suit students, lecturers, lab partners and anyone who has strong feelings about Schrodinger's cat. Expect jokes about being drawn to someone with a force proportional to something, at least one about relative motion, and a few genuinely elegant ones that only work if the other person knows the equation. Delivered to the right audience these are charming. To the wrong one they are homework.
