Question
I'm reading a book about string theory, and it describes anthropic principle. Idea is clear to me, I understand this principle describes certain constants in modern physics that are so fine tuned as if to imply the existence of a creator.
I also understand how this is not true if we imagine multiverse where each universe contains different sets of rules and constants thus leading to different physical laws, where infinite amount of universes exist 1 could easily turn out to match ours.
But why is it called Anthropic principle, or better yet why Anthropic?
Explanation / Answer
The word comes from the ancient Greek meaning "pertaining to man;" 'man' here means human. The etymologyonline dictionary is helpful. The Anthropic Principle is so-named because it is fundamentally based on the fact of a human observer.
