Edwin McMillan and his Research on Transuranium Elements

On September 18, 1907, American physicist and Nobel Laureate Edwin Mattison McMillan was born. McMillan is credited with being the first ever to produce a transuranium element, neptunium. For this, he shared the Nobel Prize in Chemistry with Glenn Seaborg in 1951. Edwin McMillan – Early Years Edwin McMillan, the son of physicist Dr. Edwin Harbaugh McMillan and his wife Anne Marie McMillan, née Mattison, grew up in Pasadena, California. He entered…

The Case of J. Robert Oppenheimer

The Case of J. Robert Oppenheimer

On April 22, 1904, American physicist J. Robert Oppenheimer was born. Oppenheimer was the wartime head of the Los Alamos Laboratory and is among those who are credited with being the “father of the atomic bomb” for their role in the Manhattan Project, the World War II undertaking that developed the first nuclear weapons. Oppenheimer‘s achievements in physics included the Born–Oppenheimer approximation for molecular wave functions, work on the theory of electrons…

Edward Teller and Stanley Kubrick’s Dr. Strangelove

On January 15, 1908, Hungarian born US theoretical physicist Edward Teller, often referred to as ‘Father of the hydrogenic bomb‘, was born. Teller made numerous contributions to nuclear and molecular physics, and is considered one of the inspirations for the character Dr. Strangelove in the 1964 Stanley Kubrick movie of the same name. “There’s no system foolproof enough to defeat a sufficiently great fool.” — Edward Teller, As quoted in “Nuclear Reactions”, by…

Emilio Segrè and the Discovery of the Antiproton

On February 1, 1905, Italian physicist and Nobel Laureate Emilio Segrè was born. Segrè is best known for his discovery of the elements technetium and astatine, and the antiproton, a sub-atomic antiparticle, for which he was awarded the Nobel Prize in Physics in 1959. “If some nuclear properties of the heavy elements had been a little different from what they turned out to be, it might have been impossible to build a…
