Plutonium namedIn 1942, a secret report was submitted suggesting the name “plutonium” for artificial element 94 since it followed neptunium and uranium (elements 93 and 92). The symbols Pu and Np were also suggestions. The paper was held secret until after WW II, when it was published by the Journal of the American Chemical Society in 1948. The authors were Glenn Seaborg and Arthur C. Wahl. Since Edwin McMillan and Philip Abelson had named neptunium (discovered 8 Jun 1940) after the planet that lies outside of the orbit of Uranus, the name for the next element in the periodic table was named after the next planet, Pluto. But instead of “plutium,” the authors decided on the name “plutonium.” Seaborg said, “It just sounded better.” They also liked “Pu” instead of “Pl.”Image: Twenty micrograms of pure plutonium hydroxide in capillary tube, Sep 1942.
Character Recognition and the Secret Service
Donald Trump is walking out of the White House and heading toward his limo when an assassin steps forward and aims a gun.
A secret service agent, new on the job, shouts, “Mickey Mouse!”
This startles the would-be assassin, and he is captured.
Later, the secret service agent’s supervisor takes him aside and asks,
“What in the hell made you shout Mickey Mouse?”
(Wait for it....)
Blushing, the agent replies, “I got nervous. I meant to shout, “Donald duck!”
