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.
Newton Since his name appears in the title of this tutorial, I should probably say something about this fellow. There are many people, both past and present, whose intellect I hold in awe. But, if I were limited to a single choice, it would have to be Sir Isaac Newton.
