Bad news or terrible news

This guy was sitting in his attorney's office. "Do you want the bad news first or the terrible news?" the lawyer said.

"Give me the bad news first."

"Your wife found a picture worth a half-million dollars."

"That's the bad news?" asked the man incredulously. "I can't wait to hear the terrible news."

"The terrible news is that it's of you and your secretary."

Eugenio Beltrami

Born 16 Nov 1835; died 18 Feb 1900 at age 64.Italian mathematician and mathematical physicist known for his concepts of non-Euclidean geometry. In 1865, he published a paper on how line elements on the surfaces of constant curvature could be represented by linear expressions. His approach offered a new representation of the geometry of constant curvature that was consistent with Euclidean theory. Beltrami studied elasticity, wave theory, optics, thermodynamics, and potential theory, and was among the first to explore the concepts of hyperspace and time as a fourth dimension. His investigations in the conduction of heat led to linear partial differential equations. Some of Beltrami's last work was on a mechanical interpretation of Maxwell's equations.
