Late one Sunday afternoon, a blonde from a Pennsylvania small town was taking a long walk through a nearby meadow, when she was surprised to see a parachutist trapped in the high branches of a tree.
"Help!" he cried when he spotted her down below.
"What are you doing up there?" she called back.
"I was skydiving," he answered, "and my parachute didn't open!"
The blonde rolled her eyes: "Well, of course it didn't. If you'd just asked one of the locals, anybody could've told you that nothing around here opens on a Sunday!"

Girolamo Cardano

Died 21 Sep 1576 at age 74 (born 24 Sep 1501). Italian physician, mathematician and astrologer who was the first to give a clinical description of typhus fever. His book, Ars magna ("Great Art," 1545) was one of the great achievements in the history of algebra, in which he published the solutions to the cubic and quartic equations. His mechanical inventions included the combination lock, the compass gimbal consisting of three concentric rings, and the universal joint to transmit rotary motion at various angles (as used in present-day vehicles). He contributed to hydrodynamics and held that perpetual motion is impossible, except in celestial bodies. Cardano published two encyclopedias of natural science, introduced the Cardan grille, a cryptographic tool (1550), and was a life-long believer as an astrologer. He died by suicide.«
