Science Quotes by Robert S. Ledley (1 quote)
It’s hard to explain to people what the significance of an invention is, so it’s hard to get funding. The first thing they say is that it can’t be done. Then they say, “You didn't do it right.” Then, when you’ve done it, they finally say, “Well, it was obvious anyway.”
— Robert S. Ledley

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) --
