Medicare Coverage

The phone rings and the lady of the house answers, 'Hello.'
'Mrs. Sanders, please.'
'Speaking.'
'Mrs. Sanders, this is Doctor Jones at Saint Agnes Laboratory. When your husband's doctor sent his biopsy to the lab last week, a biopsy from another Mr. Sanders arrived as well. We are now uncertain which one belongs to your husband. Frankly, either way the results are not too good.'
'What do you mean?' Mrs. Sanders asks nervously.
'Well, one of the specimens tested positive for Alzheimer's and the other one tested positive for HIV. We can't tell which is which.'
'That's dreadful! Can you do the test again?' questioned Mrs. Sanders.
'Normally we can, but Medicare will only pay for these expensive tests one time.'
'Well, what am I supposed to do now?'
'The folks at Medicare recommend that you drop your husband off somewhere in the middle of town. If he finds his way home, don't sleep with him.'

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.
