The Expulsion of the Portuguese Jews and the Paris Shootings
Shortly after the exile of the sultan of Granada in 1492, Queen Isabella of Castile expelled the Jews from Spain. Many of these Jews moved to Portugal which was more tolerant of Jews (relatively speaking). But Portugal's King Manuel the 1st wished to unite Spain and Portugal through a marriage with Queen Isabella's daughter. The Queen agreed to the marriage of her daughter on condition that King Manuel expel all the Jews from Portugal. A few days after signing the marriage contract King Manual signs the decree to rid Portugal of the Jews in less than year. He also decrees that all Jewish children from age 4 to 20 are to be taken from their parents and forcibly baptized as Christians. Isaac ibn Zachin [Isaac e-bin zak-KEEN] killed all of his children rather than see them become Christians. He then killed himself. Other Jews converted to Christianity but maintained their rituals in secret. Some sailed to Portugal's island possessions such as São Tomé off the coast of west Africa. By next year 20,000 Jews who could not get out of Portugal will be enslaved. A new synagogue will not be built in Lisbon until 1904.    
Leonardo's Broken Flight *
Leonardo da Vinci was fascinated with birds in flight and his enthusiasm has led to drawings of flying machines, possibly gliders, a parachute and even an early helicopter. Some time early this year, Leonardo tests one of his designs for a flying machine. He sends his assistant out with the device, but after the man breaks his leg, it is back to the drawing board. It is not clear which of these designs was tested but like Archimedes, some of his ideas remained on the drawing board to come down to us in the modern day to stimulate the imagination.
