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.

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.

Dogs are a window on the natural world.

My motivation and aspiration is the same, being number one or being number five. So that's the truth. And my goal is the same - it's to always be happy playing, it's to enjoy the game and improve always.

If you have a major disaster involving hundreds of thousands, or in this case millions of people, whether it be a natural disaster or an act of terrorism, the first 72 hours are going to be totally chaotic no matter what you plan to do.

I think, having done 'The Princess Diaries,' it was a fun experience, and it's cool to have made fans that are now into all this music. That movie is still so relevant to our culture. It's always on. It's kind of a rare, nostalgic thing. I get tweets all the time about it.

Forty is the line of demarcation that says you're an adult now. You're an adult, so don't pretend you're a kid anymore.

Scratch a Yale man with both hands and you'll be lucky to find a coast-guard. Usually you find nothing at all.

Memory as an article of faith often comes naturally to writers, who by temperament are likely to be diarists and record keepers, forever searching past events for elusive patterns - and forever believing that such patterns are to be found.

If you do build a great experience, customers tell each other about that. Word of mouth is very powerful.

In my life, it's always been about who I'm going to collaborate with. Less important to me is what the subject is.

If you want to run a mile, then run a mile. If you want to experience another life, run a marathon.

At twilight time the smog makes a rainbow.

Ireland is a good place to start out as a filmmaker. If what you do is good, even at a very small scale, it will get recognized.

Nowadays, there are sometimes more producers than there are people in the cast, because it takes that much money to put a show on.

It's too late for me to get married before I'm famous. You never know people's intentions.

My advice to young wrestlers is that your surroundings really make a difference. You want to put yourself in good, positive surroundings.

I've made some mistakes before.

You have to pick the places you don't walk away from.

I've never had to fend for a child's life, which sounds very terrifying.

My passion for giving is no different than yours. I give because it's in my heart to give. I give because I was taught to give at a very early age. This is how I developed my passion for giving.

I suppose I have become a sort of living monument in Portugal. But I come from a family with roots all over the world, so the idea of patriotism is not very strong in me. My country is the country of Chekhov, Beethoven, Velasquez - writers I like, painters and artists I admire.

Underperforming hospitals or units should accept that they have to improve the service they offer or that patients, quite properly, will go elsewhere.

A good aphorism is too hard for the tooth of time, and is not worn away by all the centuries, although it serves as food for every epoch.

In Colombia, education is sometimes considered a luxury, not a human right. And it's not a priority in the agendas of many leaders.

Good intentions often get muddled with very complex execution. The last time the government tried to make taxes easier it created a 1040 EZ form with a 52 page help booklet.
