William Newcomb

Template:Short description Template:Use dmy dates William Newcomb (1927 – 29 May 1999) was an American theoretical physicist and professor at the University of California's Lawrence Livermore Laboratory, who is best known as the creator of Newcomb's paradox, devised in 1960.<ref name=nahin19>Template:Cite book</ref> He was the great-grandnephew of the astronomer Simon Newcomb.<ref>Template:Cite web</ref>

Newcomb started at the Lawrence Livermore National Laboratory (then University of California Radiation Laboratory) probably in 1955 in the Energy Directorate. He was also an adjunct professor in the UC Davis Livermore Department of Applied Science since 1971.

At Lawrence Livermore National Laboratory, Newcomb made significant contributions to plasma physics through his pioneering work on magnetic mirrors, a plasma confinement concept for nuclear fusion. His two seminal publications in this field were "Gyroscopic-quasielastic fluid systems" (published in Annals of Physics in 1973)<ref>Template:Cite journal</ref> and "Equilibrium and stability of collisionless systems in the paraxial limit" (published in Journal of Plasma Physics in 1981).<ref>Template:Cite journal</ref> These works established fundamental theoretical frameworks that advanced understanding of plasma behavior in magnetic confinement systems.
