Moshe Reads an Arab Newspaper

A story is told of a Jewish man who was riding on the subway reading an Arab newspaper. A friend of his, who happened to be riding in the same subway car, noticed this strange phenomenon. Very upset, he approached the newspaper reader.
"Moshe, have you lost your mind? Why are you reading an Arab newspaper?"Moshe replied, "I used to read the Jewish newspaper, but what did I find? Jews being persecuted, Israel being attacked, Jews disappearing through assimilation and intermarriage, Jews living in poverty. So I switched to the Arab newspaper. Now what do I find? Jews own all the banks, Jews control the media, Jews are all rich and powerful, Jews rule the world. The news is so much better!"

Guillaume Rondelet

Born 27 Sep 1507; died 30 Jul 1566 at age 58.French naturalist and physician who contributed substantially to zoology by his descriptions of marine animals, primarily of the Mediterranean Sea. After studying at Montpellier, he later travelling widely through Europe with his patron Cardinal Tournon. Returning to Montpellier in 1545, he taught medicine. His real interest, however, was zoology, and in 1554 he published his massive compendium on aquatic life, Libri de piscibus marinis in quibus verae piscium effigies expressae sunt, which covered far more marine life than any earlier work in the field. This laid the foundation for later ichthyological research and was the standard reference work for over a century. He also published various other works on diagnosis and several pharmacological works.
