I was looking at US News graduate rankings and noticed that they have a little description for each subfield they rank ([url=<a href=“http://grad-schools.usnews.rankingsandreviews.com/best-graduate-schools/top-science-schools/mathematical-analysis-rankings%5Dlink%5B/url”>http://grad-schools.usnews.rankingsandreviews.com/best-graduate-schools/top-science-schools/mathematical-analysis-rankings]link[/url] to example). Considering that these sentences are supposed to be read by students applying to graduate programs, some of them are kind of silly:
Mathematics
“Graduate students in algebra, number theory and algebraic geometry courses build upon knowledge first learned in grade school.”
“Earning your graduate degree in mathematical analysis will mean taking courses in both real analysis and complex analysis, as well as training in key theories and functions.”
“For students who enjoy reasoning, a graduate degree in logic will help them understand theories and methods and may prepare them for teaching jobs, research appointments and government positions.”
Theories and methods! 
History
“Famous historical figures such as Napoleon Bonaparte, Karl Marx and Adolf Hitler have helped shape European history.”
“Since the end of the Civil War, American literature has been influenced by major national events, such as the Depression and World War II.”
“Shakespeare may be one of the most famous English authors, but courses in Medieval and Renaissance literature will expose you to many other works.”
“The study of Latin American history highlights events, political culture and racial issues in countries including Brazil and Chile as well as in the Caribbean.”
