Don't worry about anything. Go out and have a good time.

Agnostic for me would be trying to weasel out and sound a little nicer than I am about this.

It is simple, therefore it is beautiful

You see, the chemists have a complicated way of counting: instead of saying "one, two, three, four, five protons", they say, "hydrogen, helium, lithium, beryllium, boron."

If you thought you were trying to find out more about it because you're gonna get an answer to some deep philosophical question...you may be wrong! It may be that you can't get an answer to that particular question by finding out more about the character of nature. But my interest in science is to simply find out about the world.

To those who do not know mathematics it is difficult to get across a real feeling as to the beauty, the deepest beauty, of nature ... If you want to learn about nature, to appreciate nature, it is necessary to understand the language that she speaks in.

As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise expect.
