Jones came into the office an hour late for the third time in one week and found the boss waiting for him.
"What's the story this time, Jones?" he asked sarcastically. "Let's hear a good excuse for a change."
Jones sighed, "Everything went wrong this morning, Boss. The wife decided to drive me to the station. She got ready in ten minutes, but then the drawbridge got stuck. Rather than let you down, I swam across the river — look, my suit's still damp — ran out to the airport, got a ride on Mr. Thompson's helicopter, landed on top of Radio City Music Hall, and was carried here piggyback by one of the Rockettes."
"You'll have to do better than that, Jones," said the boss, obviously disappointed. "No woman can get ready in ten minutes."

Sir Lawrence Bragg

Died 1 Jul 1971 at age 81 (born 31 Mar 1890). William Lawrence Bragg was an Australian-English physicist and X-ray crystallographer who at the early age of 25, shared the Nobel Prize for Physics in 1915 (with his father, Sir William Bragg). Lawrence Bragg formulated the Bragg law of X-ray diffraction, which is fundamental for the determination of crystal structure: nλ = 2dsinθ which relates the wavelength of x-rays, λ, the angle of incidence on a crystal, θ, and the spacing of crystal planes, d, for x-ray diffraction, where n is an integer (1, 2, 3, etc.). Together, the Braggs worked out the crystal structures of a number of substances. Early in this work, they showed that sodium chloride does not have individual molecules in the solid, but is an array of sodium and chloride ions.
