### Chalk One Up For The Grandparents!

An elderly man in Miami calls his son in New York and says, "I hate to ruin your day, but I have to tell you that your mother and I are divorcing.

Forty-five years of misery is enough."

"Pop, what are you talking about?" the son screams.

"We can't stand the sight of each other any longer," the old man says.

"We're sick of each other, and I'm sick of talking about this, so you call your sister in Chicago and tell her," and he hangs up.

Frantic, the son calls his sister, who explodes on the phone, "Like heck they're getting divorced," she shouts, "I'll take care of this."

She calls her father immediately and screams at the old man, "You are NOT getting divorced! Don't do a single thing until I get there. I'm calling my brother back, and we'll both be there tomorrow. Until then, don't do a thing, DO YOU HEAR ME?" and hangs up.

The old man hangs up his phone and turns to his wife. "Okay," he says, "They're coming for Passover and paying their own airfares."

### Sir Chandrasekhara Venkata Raman

Died 21 Nov 1970 at age 82 (born 7 Nov 1888).Indian physicist whose work was influential in the growth of science in India. He was the recipient of the 1930 Nobel Prize for Physics for the 1928 discovery now called Raman scattering: a change in frequency observed when light is scattered in a transparent material. When monochromatic or laser light is passed through a transparent gas, liquid, or solid and is observed with the spectroscope, the normal spectral line has associated with it lines of longer and of shorter wavelength, called the Raman spectrum. Such lines, caused by photons losing or gaining energy in elastic collisions with the molecules of the substance, vary with the substance. Thus the Raman effect is applied in spectrographic chemical analysis and in the determination of molecular structure.
