Most people say that it is the intellect which makes a great scientist. They are wrong: it is character.

Our record number of teenagers must become our record number of high school and college graduates and our record number of teachers scientists doctors lawyers and skilled professionals.

It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.

The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.

When a scientist is ahead of his times it is often through misunderstanding of current rather than intuition of future truth. In science there is never any error so gross that it won't one day from some perspective appear prophetic.

Scientists will eventually stop flailing around with solar power and focus their efforts on harnessing the only truly unlimited source of energy on the planet: stupidity. I predict that in the future scientists will learn how to convert stupidity into clean fuel.

I don't think of myself as a comedian but as an artist a scientist and chemist who just happens to be funny. I started doing stand-up to add another level to my game. I feel that I'm a young rookie with a veteran's skill.

I am but one member of a vast team made up of many organizations officials thousands of scientists and millions of farmers - mostly small and humble - who for many years have been fighting a quiet oftentimes losing war on the food production front.

My whole damn family was nice. I don't think I've imagined it. It's true. Maybe it has to do with being brought up as Christian Scientists. Half of my relatives were Readers or Practitioners in the church.

I have learned to have more faith in the scientist than he does in himself.
