Justice jokes

17 July is Day of International Criminal Justice. Raise awareness, and laugh with some jokes!

"What’s the good news?"
"Your cholesterol level is good."

Attorney: "How was your first marriage terminated?"

Paolo Ruffini

Born 22 Sep 1765; died 10 May 1822 at age 56.Italian mathematician and physician who made studies of equations that anticipated the algebraic theory of groups. He is regarded as the first to make a significant attempt to show that there is no algebraic solution of the general quintic equation (an equation with the variable in one term raised to the fifth power). In 1799 Ruffini published a book on the theory of equations with his claim that quintics could not be solved by radicals, General theory of equations in which it is shown that the algebraic solution of the general equation of degree greater than four is impossible. Ruffini used group theory in his work but he had to invent the subject for himself. He also wrote on probability and the application of probability to evidence in court cases.
