Science is not perfect. It's often misused it's only a tool, but it's the best tool we have. Self-correcting , ever changing, applicable to everything: with this tool, we vanquish the impossible.

Science is a way of thinking much more than it is a body of knowledge.
Carl Sagan

Carl Sagan

He didn't want to believe. He wanted to know.
Carl Sagan

The simplest thought, like the concept of the number one, has an elaborate logical underpinning.
Carl Sagan

The nuclear arms race is like two sworn enemies standing waist deep in gasoline, one with three matches, the other with five.
Carl Sagan
Image
Every time you look up at the sky, every one of those points of light is a reminder that fusion power is extractable from hydrogen and other light elements, and it is an everyday reality throughout the Milky Way Galaxy.
Carl Sagan
Image
If we say that God has always been, why not save a step and conclude that the universe has always been?
Carl Sagan
Image
It's perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential population growth. Jobs and wages depend on science and technology.
Carl Sagan
Image
Personally, I would be delighted if there were a life after death, especially if it permitted me to continue to learn about this world and others, if it gave me a chance to discover how history turns out.
Carl Sagan

The cure for a fallacious argument is a better argument, not the suppression of ideas.
Carl Sagan
