Electric motor

In 1904, the first direct current, interpole, electric motor to be patented in the U.S. was issued to Mathias Pfatischer of Phildadelphia, Pennsylvania under the title "Variable Speed Motor" (No.775,310). His improvement was to "effect commutation without sparking, with a variable load as well as at variable speed and which is capable of rotation in either direction." The new design added auxiliary-field pole-pieces which were small as compared to the main pole-pieces.«

I Want to Be a Pastor When I Grow Up

After a church service on Sunday morning, a young boy suddenly announced to his mother, “Mom, I’ve decided to become a priest when I grow up.”“That’s OK with us,” she said, “but what made you decide that?”“Well,” said the little boy, “I have to go to church on Sunday anyway, and I figure it will be more fun to stand up and yell than to sit down and listen.”
