Criminal Minds Quotes

Reid: Huh.
Morgan: What? You see something?
Reid: Encryption's a highly specialized skill set but it's fundamentally a mathematical process, which means the human process sometimes through technique can reveal where you learned it. I think I know where he learned how to do this.
Kate: Where?
Reid: Harvard. Which oddly enough isn't known for its advanced math program but it is known for one particular class. When you're good at math - good enough to get into Harvard - you take a math class called "Math 15". When you're better than that you take "Math 25", but when you're the best, the absolute best, you take "Math 55": Honors Advanced Calculus and Linear Algebra. Graduates are immediately employed by the U.S. Government because they're too dangerous to work anywhere else. More specifically, they're employed at the NSA.

Your memory is a monster. It summons with a will of its own. You think you have a memory but it has you - John Irving.
