Playlist "Great Minds, Great Words":• ---Please SUBSCRIBE to Science & Reason:• Richard Feynman (1918-1988) was an American physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics (he proposed the parton model). For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He assisted in the development of the atomic bomb and was a member of the panel that investigated the Space Shuttle Challenger disaster.

Antares is a red supergiant star in the Milky Way galaxy and the sixteenth brightest star in the nighttime sky (sometimes listed as fifteenth brightest, if the two brighter components of the Capella quadruple star system are counted as one star). The Pistol Star is a blue hypergiant and is one of the most luminous known stars in the Milky Way Galaxy. Rigel (β Ori / β Orionis / Beta Orionis) is the brightest star in the constellation Orion and the sixth brightest star in the sky, with visual magnitude 0.18.
