Amy's Apartment Speculation
I have a theory about Amy's apartment. It's numbered as apartment 314. Now 314 looks a lot like 3.14 which is the equivalent of pi. Now, you have to understand that pi is an irrational number, one of the weirdest ones actually. What makes it irrational is the fact that it is a real number that cannot be expressed as a ratio. What does this have to do with Sheldon and Amy? Sheldon's whole life has been full of rational actions and methods. I believe that 314 represents how Amy has been the most unpredictable, irrational thing in his life thus far. She is his true love and this is something which he cannot express easily. As well as for Amy, the aparment being the first time she took the chance and kissed Sheldon, also when she lost all rational thought and faked being sick. Besides that, it is an infinite number which is what has led to all the infinite occasions where Sheldon has let his rational side leave as soon as he reaches her doorway. Point is, that apartment is where infinite amounts of love have taken place, and where I believe many more shall occur.
