I went in with Jack and Leslie, into this room that was lined with brick, and there on the side I can remember very clearly was this small model with plates for the bases - the original model with everything screwed together.

He told me that Francis Crick and Jim Watson had solved the structure of DNA, so we decided to go across to Cambridge to see it. This was in April of 1953.

During this period, I became interested in how the new techniques of cloning and sequencing DNA could influence the study of genetics and I was an early and active proponent of the Human Genome Sequencing Project.

There was still food rationing in England and life was difficult all through my 2 year stay in Oxford.

The modern computer hovers between the obsolescent and the nonexistent.

I completed the first three years of primary school in one year and was admitted to the local school the age of six directly into the fourth year, some two years younger than all my contemporaries.

I set up a laboratory in the Department of Physiology in the Medical School in South Africa and begin to try to find a bacteriophage system which we might use to solve the genetic code.

In 1995, I founded The Molecular Sciences Institute with a gift from the Philip Morris Company where I hoped that we could create an environment where young people could pursue science in an atmosphere of harmonious purpose and high intellectual challenge.

In my second year, after moving to the Medical School, I began the courses of Anatomy and Physiology. I had begun to see that I was interested in cells and their functions.

I also became interested in chemistry and gradually accumulated enough test tubes and other glassware to do chemical experiments, using small quantities of chemicals purchased from a pharmacy supply house.

So that's when I saw the DNA model for the first time, in the Cavendish, and that's when I saw that this was it. And in a flash you just knew that this was very fundamental.

The moment I saw the model and heard about the complementing base pairs I realized that it was the key to understanding all the problems in biology we had found intractable - it was the birth of molecular biology.

Living most of the time in a world created mostly in one's head, does not make for an easy passage in the real world.

Many have gone on to do important scientific work but all remember those wonderful times when we and our science were young and our excitement in meeting new challenges knew no bounds.

I lived at home and I cycled every morning to the railway station to travel by train to Johannesburg followed by a walk to the University, carrying sandwiches for my lunch and returning in the evening the same way.

I went in with Jack and Leslie, into this room that was lined with brick, and there on the side I can remember very clearly was this small model with plates for the bases - the original model with everything screwed together.

Few men would dare to read their own autobiography if all their deeds were recorded in it; few can look back upon their entire career without a blush.

I want to play roles that I'm proud of, that I feel a certain integrity about, and I want to continue to be truthful in the work that I do.

You can get help from teachers, but you are going to have to learn a lot by yourself, sitting alone in a room.

When I was 20, I didn't give a damn about song construction. I just wanted to make as much noise and play as fast and as loud as possible.

Even if I died in the service of the nation, I would be proud of it. Every drop of my blood... will contribute to the growth of this nation and to make it strong and dynamic.

When I'm on the road, I wake up early and walk a lot. I'm very healthy. But when I come back home, I am more tempted by guilty pleasures, such as eating too many sweets and sleeping a lot.

Traveling is difficult when you go for long stretches at a time, but you always come back refreshed, feeling that you've accomplished something. I'm on my knees before I go anywhere in this world.

I fell in love with '50s hot-rod, pinup-girl culture.

Any time the president talks, you listen.

We have a lot of thoughtful people in the U.S. Senate.

Back when Detroit was the head of auto manufacturing, it was clear where profits were created. Right? A car was made in Detroit. There was little argument that you could make that some of the money from that should be sent overseas to Ireland.

At least half the mystery novels published violate the law that the solution, once revealed, must seem to be inevitable.

I have a memory, and I can just eliminate mistakes when they come up because I've already made them.

We're designed for persistence hunting, which is a mix of running and walking. What's built into that kind of running is a sense of pleasure. You are designed and built and perfect for this activity, and it should be enjoyable and fun.

To do work that's not going to be fulfilling doesn't make sense.

I don't believe in frontiers, and I don't believe in races or nationalities.

You have to be narcissistic to be an artist. You have to think you are the centre of the whole thing; otherwise, why do you create? The only thing is to recognise it, and then you make the best of it.

I honestly think I could sit down and write a show tonight that the critics would love, and I know it would be canceled within four weeks. I know what the critics love. We write and produce for people, not for critics.

All human life at every stage of its development is worthy of protection.

You can learn not to want what you want, to recognize desires but not be controlled by them.

True religion comes not front the teaching of men or the reading of books; it is the awakening of the spirit within us, consequent upon pure and heroic action.

I gladly accepted the commission but was uncertain about what the end result would be. On the one hand, Cuban music was conquering the world; being heard everywhere, and our small island was already producing one of the popular musical genres of the 20th century.

I like nonsense, it wakes up the brain cells. Fantasy is a necessary ingredient in living, it's a way of looking at life through the wrong end of a telescope. Which is what I do, and that enables you to laugh at life's realities.

Kings are the slaves of history.
