“It is to be emphasized that no matter how many [amplitude] arrows we draw, add, or multiply, our objective is to calculate a single final arrow for the event . Mistakes are often made by physics students at first because they do not keep this important point in mind. They work for so long analyzing events involving a single photon that they begin to think that the arrow is somehow associated with the photon [rather than with the event].”
About This Quote
Source Lecture: “Quantum Mechanics and the Arrow of Time” (Caltech, 1965)
Stresses that in physics, multiple calculations must converge to a single result; students err by attributing properties to particles rather than events.
In simple terms: Physics calculations must focus on the event, not the particle.
Key Takeaway
Always target the final outcome, not intermediate artifacts.
