I moved offices a month ago or so.
In my new office there's a whiteboard which I haven't used, but which still has some of the previous occupant's work on it.
Over most of the board they've correctly worked through a couple of loop-level Feynman diagrams (a fairly complicated task). As the last step they've attempted to sum the contributions from different processes and get an approximation of the total. This step is written as:
900
225
100
------
1325 (answer is circled)
Classic physics.
