Edward C. Stone, 1936-2024
Edward C. Stone, Caltech's David Morrisroe Professor of Physics, Emeritus, passed away on June 9. He was 88 years old.
A giant in the fields of space physics and planetary astronomy, Stone spent six decades at Caltech, leading numerous space missions, overseeing the construction of the W. M. Keck Observatory, establishing the Institute's Space Radiation Lab, serving in distinguished leadership roles, and paving the way for the next generation of giant telescopes.
Stone was perhaps best known for his role as project scientist for NASA's twin Voyager spacecraft, a project of discovery that he spearheaded for 50 years. Always bringing a sense of wonder, an encyclopedic knowledge, and a spirit of exploration to his work, Stone led the Voyager project through its tour of the outer planets—a remarkable journey that included the first encounter with volcanism outside Earth in 1979—and through its later years when both spacecraft made history by crossing i

"Feynman" redirects here. For other uses, see Feynman (disambiguation).
Richard Phillips Feynman (; May 11, 1918 – February 15, 1988) was an American theoretical physicist. He is best known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.
Feynman developed a widely used pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world. In a 1999 poll of 130 leading physicists worldwide bygd
