The most important piece of advice that I could give them is to take advantage of the tremendous reservoir of knowledge that’s out there today. Spend some time learning how the world has evolved. There are a lot of good lessons in history, and other peoples’ experiences in the past, that could be exactly the solution to the problem you’re looking for.

By the way, the guys with very high grades are not necessarily the people that are the most successful in later life. They may be the ones that can regurgitate gracefully, and they get very high grades. But if the guys that have to work for it and do not have such good grades can do something extra, and prove that they can perform, they may have a chance.

My advice to everyone is: “Become a journalist.” ... if you have a chance to be a newspaper reporter for three or four years — before you do whatever you want to do — do it, because you will know so much.

So any student who wants to get into psychology, right now the students are like lemmings. They say, “Well, it’s popular to study brain science, I’ll do that.” Or, “It’s popular to do neural networks; I see 30,000 people doing it, it must be good.” And my advice is if a lot of people are doing it, don’t waste your time.

There was no importance to what I was doing, but ultimately there was.  The diagrams and the whole business that I got the Nobel Prize for came from that piddling around with the wobbling plate.

I don’t believe I can really do without teaching.  The reason is, I have to have something so that when I don’t have any ideas and I’m not getting anywhere I can say to myself, “At least I’m living; at least I’m doing something; I’m making some contribution”—it’s just psychological.

It is necessary, I believe, to accept this idea, not only for science, but also for other things; it is of great value to acknowledge ignorance.  It is a fact that when we make decisions in our life we don't necessarily know that we are making them correctly; we only think that we are doing the best we can – and that is what we should do.

We'd walk in the canyons, and we'd often walk with Bethe, and Von Neumann, and Bacher. It was a great pleasure.

It was a brilliant idea: You have no responsibility to live up to what other people think you ought to accomplish.  I have no responsibility to be like they expect me to be.

the colonel said I shouldn't tell them how the neutrons work and all the details because we want to keep things separate, so just tell them what to do to keep it safe.
