Simple machines make work easier for us by allowing us to push or pull over increased distances.
It was perfectly normal to have no middle name. um... well.... Sir Isaac Newton didn't have a middle name. im serious. belive me. i knew that for 3 years already becasue we learned about him 3 years ago. i studied alot about him. <br /><br />[edit to improve]: During his time period, many people didn't have middle names, and some only had initials, such as Harry S. Truman.
Bottom line: Isaac Newton was born on January 4, 1643 (December 25, 1642, in the same year that Galileo died, in the old style Gregorian calendar). His work laid much of the foundation for our modern understanding of the physical universe.
