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.”
