Science Quotes by Louis D. Friedman (1 quote)
Space exploration is risky. It’s hard. And actually, let me say here that I feel like we need to take on more risk than we have been in space exploration. The public doesn’t like risk, and they hate failure. But failures happen. They shouldn’t happen for stupid reasons. But if they happen when you were trying something risky, you learn. That teaches you something. At least it should. And you try harder next time.
— Louis D. Friedman
On the failure of the Cosmos-1 solar sail (Jun 2005).
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
