Polishing Apples

A young man asked an old rich man how he made his money.
The old guy fingered his expensive wool vest and said, "Well, son, it was 1932. The depth of the Great Depression. I was down to my last nickel."
"I invested that nickel in an apple. I spent the entire day polishing the apple and, at the end of the day, I sold the apple for ten cents."
"The next morning, I invested those ten cents in two apples. I spent the entire day polishing them and sold them at 5:00 pm for 20 cents. I continued this system for a month, by the end of which I'd accumulated a fortune of $9.80."
"Then my wife's father died and left us two million dollars."

Plutonium named

In 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.
