A farmer named Muldoon lived alone in the Irish countryside except for a pet dog he for a long time.

The dog finally died and Muldoon went to the parish priest, saying "Father, the dog is dead. Could you possibly be saying a Mass for the poor creature?"

Father Patrick told the farmer "No, we can't have services for an animal in the church, but I'll tell you what, there's a new denomination down the road apiece, and no telling what they believe in, but maybe they'll do something for the animal."

Muldoon said "I'll go right now. By the way, do you think \$50,000 is enough to donate for the service?"

Father Patrick replied "Why didn't you tell me the dog was Catholic."

### Francesco Maria Grimaldi

Born 2 Apr 1618; died 28 Dec 1663 at age 45.Italian physicist and mathematician who studied the diffraction of light. He observed the image on a screen in a darkened room of a tiny beam of sunlight after it passed pass through a fine screen (or a slit, edge of a screen, wire, hair, fabric or bird feather). The image had iridescent fringes, and deviated from a normal geometrical shadow. He coined the name diffraction for this change of trajectory of the light passing near opaque objects (though, more specifically, it may have been interferences with two close sources that he observed). This provided evidence for later physicists to support the wave theory of light. With Riccioli, he investigated the object in free fall (1640-50), and found that distance of fall was proportional to the square of the time taken.«
