People who wish to analyze nature without using mathematics must settle for a reduced understanding.

Another thing I must point out is that you cannot prove a vague theory wrong.

Thank you very Much, I enjoyed myself

Poets say science takes away from the beauty of stars-mere globs of gas atoms. Nothing is "mere". I too see the stars on a desert night, and feel them. But do I see less or more? ...What is the pattern, or the meaning, or the why? It does not do harm to the mystery to know a little more about it. For far more marvelous is the truth than any artists of the past imagined it.
