You travel across the country, you visit departments, you give talks, you talk about the work at your laboratory - what's going on, what the opportunities are there - you talk about your own research.

I was strongly encouraged by a science teacher who took an interest in me and presented me with a key to the laboratory to allow me to work whenever I wanted.

I wound up getting offered a job at the NASA Jet Propulsion Laboratory where I invented a power supply mechanism for the Galileo space craft which was in orbit around Jupiter until 2003.

The International Space Station is a phenomenal laboratory, an unparalleled test bed for new invention and discovery. Yet I often thought, while silently gazing out the window at Earth, that the actual legacy of humanity's attempts to step into space will be a better understanding of our current planet and how to take care of it.

Our laboratory is a place that celebrates diversity and is totally open to all differences, not just sex but also age, ethnicity, religion and other traditions.

I consider nature a vast chemical laboratory in which all kinds of composition and decompositions are formed.

In preparation for a career in academic medicine, I worked as a medical house officer at Columbia-Presbyterian Hospital from 1966 to 1968 and then joined Ira Pastan's laboratory at the National Institutes of Health as a Clinical Associate.

Here at the Cold Spring Harbor Laboratory, we have genetically rearranged various viruses and bacteria as part of our medical research. In fact, we have been able to create entirely new types of DNA molecules by splicing together the genetic information from different organisms - recombinant DNA.

Now a cholera epidemic was sweeping through Southeast Asia and south Asia in the early 1970s, so I started medical school and I joined a laboratory to work on this.

In the Radiation Laboratory we count it a privilege to do everything we can to assist our medical colleagues in the application of these new tools to the problems of human suffering.

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.

The space station is the most unique laboratory we've ever built. The reason we have it is to do research on materials, people, medical matters, pharmaceuticals - the possibilities are nearly endless.

Put off your imagination, as you put off your overcoat, when you enter the laboratory. Put it on again, as you put on your overcoat, when you leave.

It is not only my laboratory and my place of work but also my home, so that on the 30th October I was able to share my happiness immediately with my students and collaborators and, at the same time, with my wife and family.

Just after graduation in 1966, like many of my contemporaries, I applied for research training at the National Institutes of Health. Perhaps because his wife was a poet, Ira Pastan agreed to take me into his laboratory, despite my lack of scientific credentials.

The kitchen's a laboratory, and everything that happens there has to do with science. It's biology, chemistry, physics. Yes, there's history. Yes, there's artistry. Yes, to all of that. But what happened there, what actually happens to the food is all science.

What we do in the laboratory is we try to design drugs that will not just eradicate cancer cells but will eradicate their homes.

I joined the staff of EMI in Middlesex in 1951, where I worked for a while on radar and guided weapons and later ran a small design laboratory. During this time, I became particularly interested in computers, which were then in their infancy. It was interesting, pioneering work at that time: drums and tape decks had to be designed from scratch.

My father had a big brick cell phone, before anyone had a cell phone, because he was really just into that kind of thing - communication devices. I grew up between my father's laboratory and my mother's library.

In the numerous observations made in my laboratory upon this object, we have only once seen a combination of vessels in which there might be a direct communication between a small artery and a vein, though the two observers could not come to a final conclusion on the point.

I have been trying to point out that in our lives chance may have an astonishing influence and, if I may offer advice to the young laboratory worker, it would be this - never to neglect an extraordinary appearance or happening.

We are able to find everything in our memory, which is like a dispensary or chemical laboratory in which chance steers our hand sometimes to a soothing drug and sometimes to a dangerous poison.

Achievers have an enabling attitude, realism, and a conviction that they themselves were the laboratory of innovation. Their ability to change themselves is central to their success. They have learned to conserve their energy by minimizing the time spent in regret or complaint. Every event is a lesson to them, every person a teacher.

What, more realistically, is this "mutation," the "new man"? He is the rootless man, discontinuous with a past that Nihilism has destroyed, the raw material of every demagogue's dream; the "free-thinker" and skeptic, closed only to the truth but "open" to each new intellectual fashion because he himself has no intellectual foundation; the "seeker" after some "new revelation," ready to believe anything new because true faith has been annihilated in him; the planner and experimenter, worshipping "fact" because he has abandoned truth, seeing the world as a vast laboratory in which he is free to determine what is "possible"; the autonomous man, pretending to the humility of only asking his "rights," yet full of the pride that expects everything to be given him in a world where nothing is authoritatively forbidden; the man of the moment, without conscience or values and thus at the mercy of the strongest "stimulus"; the "rebel," hating all restraint and authority because he himself is his own and only God; the "mass man," this new barbarian, thoroughly "reduced" and "simplified" and capable of only the most elementary ideas, yet scornful of anyone who presumes to point out the higher things or the real complexity of life.
