### Bubba had shingles. Those of...

Bubba had shingles. Those of us who spend much time in a doctor's office should appreciate this! Doesn't it seem more and more that physicians are running their practices like an assembly line?
Here's what happened to Bubba:
Bubba walked into a doctor's office and the receptionist asked him what he had. Bubba said: 'Shingles.' So she wrote down his name, address, medical insurance number and told him to have a seat.
Fifteen minutes later a nurse's aide came out and asked Bubba what he had.
Bubba said, 'Shingles' So she wrote down his height, weight, a complete medical history and told Bubba to wait in the examining room.
A half hour later a nurse came in and asked Bubba what he had. Bubba said, 'Shingles...' So the nurse gave Bubba a blood test, a blood pressure test, an electrocardiogram, and told Bubba to take off all his clothes and wait for the doctor.
An hour later the doctor came in and found Bubba sitting patiently in the nude and asked Bubba what he had.
Bubba said, 'Shingles.' The doctor asked, 'Where?'
Bubba said, 'Outside on the truck. Where do you want me to unload 'em??'

### 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.
