If you meet somebody who says he or she has never dreamed of flying, I don't believe you. I mean, they're lying.

SCIENCE is a part of EVERYONE'S everyday life.

Unlike science, creationism cannot predict anything, and it cannot provide satisfactory answers about the past.

Our goal in science is to discover universal laws of nature. If one's faith requires one to abandon or ignore natural laws, well, that person is going to have trouble reconciling religion and science. Otherwise, there is no any conflict.

If you just take a single human and put him or her in the forest he or she might not do very well without some sort of education which he got or she got from some tribe.

It is my mission to change the world. I'm not kidding: Make no small plans, dream mighty things. I feel if we get enough people engaged in climate change, we will get enough people to change the world. We will revolutionize the way we produce electricity and provide clean water to people.

The most serious problem facing humankind is climate change.
