Keep in mind that this outline is a general idea, and that there will most likely be several changes made during the creation of the actual speech.
Edit: After a bit of inspiration, I’ve decided I might use a completely different plan instead.
-Upbringing (Father nurtures curiosity, learning about physics at young age, science can be fun)
-MIT + Princeton (High level education, this will just be a brief mention)
-Los Alamos (Atomic bomb research, practical jokes (mention), this was the big leagues)
-Quantum Electrodynamics (complexity, brief description of what it is)
-Schwinger, Dyson, and Oppenheimer (Rivalry, debate, confusion, searching for solutions)
Climax + Falling action:
-Feynman Diagrams (Simple and elegant solution to complex problem, visualization, Feynman’s way of thinking)
-Lectures (straightforward way of speaking makes them approachable by non-scientists, shows passion for job [in the zone], maybe mention the fact that they’re quoted/referenced a lot even today)
-Challenger (O-ring experiment)
-Feynman’s last words (“I’d hate to die twice. It’s so boring.”) or a general last word about everything.
