Quotations
Carl Sagan
The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.
The cosmos is interesting rather than perfect, and everything is not part of some greater plan, nor is all necessarily under control.
