My View:
It seems that people, no matter who you are or where you're from can get a bloated head about their accomplishments. Although their findings may be very important it is still very important to keep your humbleness because you never know when your theory will be proven wrong. With that said I felt it was necessary to put humans at the bottom, like Mr. Einstein. The next level up are the actual theories and they are ranked by how famous or how often mentioned or discussed. Also the more basic theories/ events are closer to the top.
