A scientist has to decide: Is he right or is he wrong? And other people won’t necessarily agree with you. Two very prominent professors in my department came in one day and said, “Look, you know that’s not going to work. We know it’s not going to work. Why don’t you just stop bothering with it, and wasting time, wasting time and money?” I had spent I guess about 30,000 dollars building this up. And they assured me it wasn’t going to work. Now, I had of course been working with it long enough, and thought about it enough that, well, I still think it has a good chance. And so I continued, and a couple of months later it was working. Now also, one should realize that many people came to my laboratory and looked at this, they weren’t terribly excited about it. They said, “Well, you know, that’s a kind of a nice idea.” But nobody else tried to do it. It wasn’t that interesting to other people at that time. They hadn’t yet really grasped what it meant. And everybody was looking at it, “Well yes, okay, that’s a kind of nice idea,” but some doubted it would work. And nobody else was interested enough to try to do it, even though they knew all about what I was trying to do. I had showed them. So we could take two-and-a-half years — no competition — we just went our own course, and did the things we thought had some chance. And it turned out well. Now, it might have not turned out so well. It would have been interesting in any case, but maybe not quite so successful. So it was worth exploring, I was sure of that.
