I want to persuade people that Culture, broadly defined (literature, philosophy, art, theatre, photography etc.) can be used as a guide to how to live. I believe in the practical application of Culture, Culture as self-help.

I believe in Test cricket, but at the end of the day, I’m a professional. It wasn’t part of my journey. I have no regrets because it wasn’t me that turned my back.

Pix is probably the most successful payment infrastructure run by a government in history. I think Pix has been what has allowed a country like Brazil to leapfrog developed economies like the U.S. and in Europe, and has positioned Brazil today probably five years ahead of the U.S. I don't think anybody understands that, and probably in the U.S. they didn't really expect that.

Science for me is a language of peace and the only one I know which is absolutely international. I can talk to a UK scientist or any scientist worldwide about my research and they understand exactly what I am talking about. We may even find an area of mutual interest to collaborate on and together we can make an even greater impact on the world around us.

Those are important, but there is still a need for any youngster who has any scientific interest at all to continue the lead that we have on technology in the world today, if we are interested in the future of the United States.

Oh, absolutely. I was delighted when I was assigned command of the first Gemini flight with Tom Stafford as my co-pilot, but it was shortly after that I developed a disorientation problem in my ear, and NASA grounded me. I was grounded for almost six years.

And I think that still is true of this business — which is basically research and development — that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.

I think all of us certainly believed the statistics, which said that probably 88 percent chance of mission success and maybe 96 percent chance of survival. And we were willing to take those odds.

A little bit of overconfidence perhaps. A lack of attention to duty. Little insidious things that happened. You had this great team of dedicated, qualified people, but they get a little bit complacent, and boom! Pretty soon something goes wrong.

In those days, talking in terms of a hero — it had to be Charles Lindbergh. I was very young when he flew across the Atlantic, and very impressed.
