Little Zachary was doing poorl...

Little Zachary was doing poorly in math. His parents, after exhausting all other incentives, finally decided to enroll him in the local Catholic School. After the first day, Little Zachary came home with a very serious look on his face. He went straight to his room and started studying. This continued for some time. His mother was baffled as to why he had become so dedicated.
Finally, Little Zachary brought home his report card. He quietly laid it on the table and went to his room to study. With great trepidation, his mother looked at it and, to her surprise, Little Zachary go an "A" in math. She asked, "Son, what was it? Was it the nuns, the books, the discipline, the uniforms?"
Little Zachary said, "No!"
"What was it?" she asked.
Little Zachary looked at her and said, "Well, on the first day of school, when I saw that guy nailed to the Plus Sign, I knew they weren't fooling around."

Sir George Thomas Beilby

Died 1 Aug 1924 at age 73 (born 17 Nov 1850).Scottish industrial chemist who developed (1890) the process of manufacturing potassium cyanide (widely used to extract gold from low-grade ore) by passing ammonia over a heated mixture of charcoal and potassium carbonate. Beilby entered the oil-shale industry in 1869 and greatly increased the yield of paraffin and ammonia by introducing the continuous retort. Noting the destruction of metals by ammonia at high temperatures, Beilby researched the flow of solids. He inferred that when a solid is caused to flow, as in polishing, the crystalline surface is broken down to a harder and denser layer. Although much criticized, this theory explained the hardening of metals under cold working and gave valuable stimulus to further research.
