Science Is a Fundamental Part of America

August 3, 2017

Neil deGrasse Tyson:

“How did America rise up from a backwoods country to be one of the greatest nations the world has ever known? We pioneered industries. And all this required the greatest innovations in science and technology in the world. And so, science is a fundamental part of the country that we are. But in this, the 21st century, when it comes time to make decisions about science, it seems to me people have lost the ability to judge what is true and what is not, what is reliable what is not reliable, what should you believe what you do not believe. And when you have people who don’t know much about science standing in denial of it and rising to power, that is a recipe for the complete dismantling of our informed democracy.”
