Who Should Make the Coffee?

A man and his wife were having an argument about who should brew the coffee each morning. The wife said, "You should do it, because you get up first, and then we don't have to wait as long to get our coffee."The husband said, "You are in charge of the cooking around here so you should do it, because that is your job, and I can just wait for my coffee."Wife replies, "No, you should do it, and besides it says in the Bible that the man should do the coffee."Husband replies, "I can't believe that! Show me."So she fetched the Bible, and opened the New Testament and showed him at the top of several pages, that it indeed says, "HEBREWS."

Gaetano Arturo Crocco

Died 19 Jan 1968 at age 90 (born 26 Oct 1877).Italian pioneer in aeronautics and space science who designed revolutionary airships and patented an early cyclic pitch design for helicopter rotors (1906). While the design of helicopters was in its infancy, Crocco recognized that a way to change the pitch cyclically on the blades was needed if a helicopter was to work properly in forward flight. He designed a number of airships in the early part of the 20th century and switched to designing rocket engines in the 1920s. Crocco founded the Italian Rocket Society (1951) and made many contributions to the theory of spaceflight. He calculated that a spacecraft could travel from Earth to Mars, perform a reconnaissance Mars flyby (without orbit), and return to Earth in a total time of about one year.«
