Richard Feynman Rubber Bands

Richard Phillips Feynman was an American physicist known for the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the super fluidity of super cooled liquid helium, as well as work in particle physics (he proposed the Parton model). For his contributions to the development of quantum electrodynamics, Feynman was a joint recipient of the Nobel Prize in Physics in 1965, together with Julian Schwinger and Sin-Itiro Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime and after his death, Feynman became one of the most publicly known scientists in the world.

Richard Feynman on Discovery of Neptune

(from a Lecture on Gravitation)

The key thing here is the connection between theoretical understandings of how the universe works and practical observations. Theories are used to make predictions. When the predictions turn out to be correct, we get some more evidence that the theory is on the right track. Here, Feynman talks about how the theory of gravity led to the discovery of the speed of light, and how knowledge of the effect of gravity on planetary orbits led to the discovery of the planet Neptune. Very cool stuff.

The Feynman Series - Curiosity

Part three of the Feynman Series by Reid Gower.

Richard Feynman discusses the methodological naturalism at the foundation of 400 years of science, and the blissful experience of discovery.

The Feynman Series - Beauty

Part one of the Feynman Series by Reid Gower.

Richard Feynman discusses how his personal experience of beauty is enhanced by deep scientific knowledge. He also talks about the fallibility and incompleteness of all knowledge, and how wonderful this is.
