• Ask a theoretical physicist her phone number, and she'll tell you it's a trivial consequence of Maxwell's equations.
• Ask a mathematical physicist his phone number, and he'll tell you it's a trivial consequence of Maxwell's equations with the appropriate boundary conditions.
• Ask an experimental physicist her phone number, and she'll tell you that so far she knows it to only four significant figures
• Ask an astrophysicist his phone number, and he'll tell you it's on the order of ten to the sixth.
• Ask a computational physicist her phone number, and she'll offer to sell you a program that will try every telephone until you find hers.
