A special celebration...

While enjoying an early morning breakfast in a northern Arizona cafe, four elderly ranchers were discussing everything from cattle, horses, and weather to how things used to be in the "good old days."

Eventually the conversation moved on to their spouses. One gentleman turned to the fellow on his right and asked, "Roy, aren't you and your bride celebrating your 50th wedding anniversary soon?"

"Yup, we sure are," Roy replied.

"Well, are you gonna do anything special to celebrate?" another man asked.

The old gentleman pondered this for a moment, then replied, "For our 25th anniversary, I took the misses to Tucson. For our 50th, I'm thinking about going down there again to pick her up."

Pafnuty Lvovich Chebyshev

Born 16 May 1821; died 8 Dec 1894 at age 73. Russian mathematician who founded the St. Petersburg mathematical school (sometimes called the Chebyshev school), who is remembered primarily for his work on the theory of prime numbers, including the determination of the number of primes not exceeding a given number. He wrote about many subjects, including the theory of congruences in 1849, probability theory, quadratic forms, orthogonal functions, the theory of integrals, the construction of maps, and the calculation of geometric volumes. Chebyshev was also interested in mechanics and studied the problems involved in converting rotary motion into rectilinear motion by mechanical coupling. The Chebyshev parallel motion is three linked bars approximating rectilinear motion.[Old style dates: Born 4 May 1821; died 26 Nov 1894]
