A Quote by Emilio G. Segre
If some nuclear properties of the heavy elements had been a little different from what they turned out to be, it might have been impossible to build a bomb.

You think of what might have been different if dad had been around, or how I might have turned out as a person. You just don't know. I might not even be playing cricket.
There might have been a hundred or a thousand life-bearing planets, had the course of evolution of the universe been a little different, or there might have been none at all. They would probably add, that, as life and man have been produced, that shows that their production was possible; and therefore, if not now then at some other time, if not here then in some other planet of some other sun, we should be sure to have come into existence; or if not precisely the same as we are, then something a little better or a little worse.
We haven't been out in many of these countries helping them build infrastructure. How would they look at us today if we had been there helping them with some of that, rather than just being the people who are going to bomb in Iraq and go to Afghanistan?

We are not afraid of nuclear weapons. The point is that if we had in fact wanted to build a nuclear bomb, we are brave enough to say that we want it. But we never do that.
The nature of nuclear weapons makes it impossible to either ban the bomb or wipe out an enemy's arsenal. Nuclear deterrence was unavoidable.
The most dangerous thing Iraq could have ever had was a nuclear weapon. The nuclear weapon Iraq was trying to build was not deliverable by bomb or ballistic missile. It was a large, bulky device that they hoped to bury and set off to let the world know they had a nuclear weapon. They never achieved that.
The scientists who made the atomic bomb are, in my sense, people with a tragic destiny. You know, there was the US race with Nazi Germany and good evidence that the Germans were more advanced in nuclear physics, and we had to get the bomb first. But then there was the use of that dreadful weapon, or instrument of genocide, and many of the more sensitive scientists turned quickly into anti - nuclear people - and very effective ones.
The one great gift to humankind from our nuclear physicists has been the nuclear bomb. How can we ever thank them?
I, who had been in favour of nuclear energy for generating electricity ... I suddenly realised that anybody who has a nuclear reactor can extract the plutonium from the reactor and make nuclear weapons, so that a country which has a nuclear reactor can, at any moment that it wants to, become a nuclear weapons power. And I, right from the beginning, have been terribly worried by the existence of nuclear weapons and very much against their use.
A nuclear program has arguably worked as a deterrent for North Korea and other states - would Moammar Gadhafi have been deposed and summarily killed if Libya had had nuclear weapons? Iranians might not think so.
There has been a transition from a nuclear-annihilation scenario to an isolated-terrorist-nuclear-bomb scenario. But we're still locked into a mind-set that nuclear war would be so overwhelming that any kind of preparedness would be futile.
In an enterprise such as the building of the atomic bomb the difference between ideas, hopes, suggestions and theoretical calculations, and solid numbers based on measurement, is paramount. All the committees, the politicking and the plans would have come to naught if a few unpredictable nuclear cross sections had been different from what they are by a factor of two.
Saddam Hussein had nerve gas and used it against his own people, he had used chemical weapons against the Iranians and he almost had a nuclear bomb in 1981 and in 1991. And he had been caught with anthrax in 1995 by the UN inspections after denying that he had it.
So the idea about how detonation of a nuclear weapon might happen vary, you know - some people are especially concerned about terrorists getting their hands on nuclear weapons and using them. Some people are worried that there might be a nuclear war between India and Pakistan. Some think the Middle East, were Israel already has nuclear weapons and where other countries may be interested at some point and acquiring them, might be a flash point.
The act of living had been enjoyable; at some point when I was not paying attention, it had turned into a different sort of experience, to whose grimness I had grown so accustomed that I now took it for granted.
