My name is Dr. Sheldon Cooper. I am a Caltech theoretical physicist. I would describe myself as calculating and cynical, believing that Leonard (my roommate & colleague) is only setting himself up for disappointment as he continues to have a crush on our neighbor, Penny. I often represent the voice of reason amongst my friends, as I do not hesitate to point out the facts.
