When I entered medical physics in 1958 there were fewer than 100 in the U.S. and I could see many opportunities to apply my knowledge of nuclear physics.

I hope that none of the countries in the Middle East are planning anything but the peaceful utilization of nuclear energy.

Today I can declare my hope and declare it from the bottom of my heart that we will eventually see the time when that number of nuclear weapons is down to zero and the world is a much better place.

A world without nuclear weapons would be less stable and more dangerous for all of us.

For this generation ours life is nuclear survival liberty is human rights the pursuit of happiness is a planet whose resources are devoted to the physical and spiritual nourishment of its inhabitants.

I call upon the scientific community in our country those who gave us nuclear weapons to turn their great talents now to the cause of mankind and world peace: to give us the means of rendering these nuclear weapons impotent and obsolete.

When decisions on nuclear power stations and runways are delayed and the government dilly-dallies people think they aren't important.

There is a Western world. There is America. There is Great Britain and Germany and France and Russia and China and other nations. I doubt that there is one country amongst those I mentioned which has a desire to see Iran with its fundamentalist Islamic extremist government possessing nuclear weapons.

The nuclear arsenal that Pakistan has I believe is secure. I think the government and the military have taken adequate steps to protect that.

The Nuclear Security Summit was President Obama's initiative born out of his vision to leave behind a safer more prosperous world for the future generation.

We inadvertently bombed the Chinese Embassy. But Clinton now is working very hard. He has sent a letter of apology to the Chinese. And he's also given them a gift certificate for future nuclear secrets.

For 50 years nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task and most of the cost of making safe sites that have been polluted half-way to eternity.

I most sincerely wish that the world in which we live be free from the threat of a nuclear holocaust and from the ruinous arms race. It is my cherished desire that peace be not separated from freedom which is the right of every nation. This I desire and for this I pray.

I worked for the Office of Management and Budget in the White House on nuclear energy policy. But I decided it would be much more fun to have a specialty food store so I left Washington D.C. and moved to the Hamptons. And how glad I am that I did!

China in the future is going to have even more nuclear capability than it has had in the past. I don't believe that they have anything to fear from the United States and I frankly don't believe they do fear the United States.

The greatest fear that haunts this city is a suitcase bomb nuclear or germ. Many people carry small gas masks. The masses here seem to be resigned to the inevitable believing an attack of major proportions will happen.

Nobody has ever before asked the nuclear family to live all by itself in a box the way we do. With no relatives no support we've put it in an impossible situation.

I assume we will have figured out a way to efficiently utilize solar energy and tied that to an efficient way to use nuclear energy in such a way that it doesn't pose a serious environmental issue.

My entry into the environmental arena was through the issue that so dramatically - and destructively - demonstrates the link between science and social action: nuclear weapons.

There are nuclear weapons in China Iran Korea and Pakistan. It wouldn't take much to send a couple of warheads off on this planet somewhere that would cause a lot of environmental damage then if you have got someone who wants to retaliate you have real problems.

There are two problems for our species' survival - nuclear war and environmental catastrophe - and we're hurtling towards them. Knowingly.

Nuclear power will help provide the electricity that our growing economy needs without increasing emissions. This is truly an environmentally responsible source of energy.

The United States government first learned of the diversion of the W-88 nuclear warhead design in late 1995.

In its report the Cox Committee concludes that China is using stolen U.S. design information to speed up its deployment of a new nuclear missile force.
