  • Feynman replaces complex numbers with spinning arrows, which start at emission and end at detection of a particle. The sum of all resulting arrows gives a final arrow whose length squared equals the probability of the event. In this diagram, light emitted by the source '''''S''''' can reach the detector at '''''P''''' by bouncing off the mirror (in blue) at various points. Each one of the paths has an arrow associated with it (whose direction changes uniformly with the ''time'' taken for the light to traverse the path). To correctly calculate the total probability for light to reach '''''P''''' starting at '''''S''''', one needs to sum the arrows for ''all'' such paths. The graph below depicts the total time spent to traverse each of the paths above.

QED manifesto

The QED manifesto was a proposal for a computer-based database of all mathematical knowledge, strictly formalized and with all proofs having been checked automatically. (Q.E.D. means quod erat demonstrandum in Latin, meaning "which was to be demonstrated.")
