Why Is This Night Different?

During one of his many trips to London, George Burns became friends with a very wealthy, yet very modest, Jewish chap named Hyman Goldfarb. On one visit, Hy told George that because of his large donations to charities through the years, the queen wanted to knight him, but he was going to turn it down."That's a great honor," George said. "Why would you turn it down?""Because during the ceremony you have to say something in Latin," he said. "And I don't wish to bother studying Latin just for that.""So say something in Hebrew. The queen wouldn't know the difference.""Brilliant," Hy complimented me, "but what should I say?""Remember that question the son asks the father on the first night of Passover? ... 'Why is this night different from all other nights?' Can you say that in Hebrew?""Of course," he said. "Ma nishtana ha leila hazeh. Thank you, old sport, I shall become a knight."At the ceremony Hy waited his turn while several of the other honorees went before the queen. Finally they called his name. He knelt before Her Majesty, she placed her sword on one shoulder and then on the other, and motioned for Hy to speak.Out came "Ma nishtana ha leila hazeh."The queen turned to her husband and said, "Why is this knight different from all other knights?"

Lewis Urry

Died 19 Oct 2004 at age 77 (born 29 Jan 1927).Lewis Frederick Urry was a Canadian-American chemical engineer who invented the ubiquitous alkaline batteries and, later, lithium batteries. After a few years working in Canada for the company that made Eveready batteries, he was transferred in 1955 to its Cleveland, Ohio, laboratory where he began work on a new battery with better life-span than the carbon-zinc type of the time. He succeeded by using manganese dioxide, an alkaline electrolyte and powdered zinc (which he realized had greater surface area than solid zinc). A patent was filed 9 Oct 1957, issued 15 Nov 1960, No. 2,960,558. Production began in 1959. Alkaline batteries are estimated to be 80% of all dry cell batteries now sold in the world. The Smithsonian Institution displays his prototype alkaline battery. Urry held over 50 patents.«
