There was an elderly widow who lived in a large mansion. She was feeling generous when it came to Thanksgiving, so she called up the local military base, and asked to speak with the lieutenant.
"Please send up four nice young men to eat dinner here on Thanksgiving, but please, don't send any Jews. Please, no Jews."
The lieutenant replied, "No problem ma'am, and I am sure I speak for the army when I say we all appreciate your kindness."
Well, Thanksgiving rolled around, and the widow went to answer the door when it rang. She was surprised to see four black recruits. "But... But... There must be some mistake," she stammered.
One of them replied, "No ma'am, Lieutenant Goldstein doesn't make mistakes."

Auguste Bravais

Born 23 Aug 1811; died 30 Mar 1863 at age 51.French physicist and mineralogist, best remembered for his work on the lattice theory of crystals. Bravais lattices are named for him. In 1850, he showed that crystals could be divided into 14 unit cells for which: (a) the unit cell is the simplest repeating unit in the crystal; (b) opposite faces of a unit cell are parallel; and (c) the edge of the unit cell connects equivalent points. These unit cells fall into seven geometrical categories, which differ in their relative edge lengths and internal angles. In 1866, he elaborated the relationships between the ideal lattice and the material crystal. Sixty years later, Bravais' work provided the mathematical and conceptual basis for the determination of crystal structures after Laue's discovery of X-ray diffraction in 1911.
