Looking Heavenward

The temporary Sunday School teacher was struggling to open a combination lock on the supply cabinet. She had been told the combination, but couldn't quite remember it. She went to the pastor's study and asked for help. The pastor came into the room and began to turn the dial. After the first two numbers he paused and stared blankly for a moment.Finally he looked serenely heavenward and his lips moved silently. Then he looked back at the lock, and quickly turned to the final number, and opened the lock. The teacher was amazed. "I'm in awe at your faith, pastor," she said. "It's really nothing," he answered. "The number is on a piece of tape on the ceiling."

Georg Frobenius

Died 3 Aug 1917 at age 67 (born 26 Oct 1849).Ferdinand Georg Frobenius was a German mathematician who made major contributions to group theory, especially the concept of abstract groups (with Ludwig Stickleberger) and the theory of finite groups of linear substitutions (with Issai Schur), that later found important uses in the theory of finite groups as it applies to quantum mechanics. He also contributed to means of solving linear homogenous differential equations. The fact so many of Frobenius's papers read like present day text-books on the topics which he studied is a clear indication of the importance that his work, in many different areas, has had in shaping the mathematics which is studied today.
