quote by Enrico Fermi

The fundamental point in fabricating a chain reacting machine is of course to see to it that each fission produces a certain number of neutrons and some of these neutrons will again produce fission.

— Enrico Fermi

Contentment Fission quotations

France generates a significant part of its energy requirements from fission reactors and these have achieved a perfect safety record. We build ours all differently.

Nearly all of our existing power sources are generators which use a heat cycle.

This includes our coal, oil, and gas fired utilities, our automobiles, trucks, and trains, and even our nuclear fission utility power plants.

Rocket scientists agree that we have about reached the limit of our ability to travel in space using chemical rockets. To achieve anything near the speed of light we will need a new energy source and a new propellant. Nuclear fission is not an option.

No-one really thought of fission before its discovery.


It was my responsibility that this world got itself an atom bomb, because there were only a handful of nuclear physicists in the thirties - only a handful. And we were all beating the desk and saying "How wonderful it will be if we discover atomic fission."

Mighty little force is needed to control a man whose mind has been hoodwinked;

contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, not anything - you can't conquer a free man; the most you can do is kill him.

Modern thinking is that time did not start with the big bang, and that there was a multiverse even before the big bang. In the inflation theory, and in string theory, there were universes before our big bang, and that big bangs are happening all the time. Universes are formed when bubbles collide or fission into smaller bubles.

Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!

In the design of fission reactors man was not an innovator but an unwitting imitator of nature.


Other paths would include making nuclear fission cheap enough and safe enough that people broadly embrace it, so that could be scaled up.

You can't conquer a free man; the most you can do is kill him.

Traditional nationalism cannot survive the fissioning of the atom. One world or none.

The barbarian weapon is fission: the splitting asunder.

It has been perfected for death. Our only weapon is fusion: an imperfect process still, though designed for life.

When God speaks, when the Word speaks, energy is translated into matter.

What is atomic fission? It is matter translated back into energy—poof! it disappears. Creation began with energy. In the beginning was the Word. The Word was with God. The Word was God.


Everything we did in the 1960s was designed to fission, to weaken faith in and conformity to the 1950s social order. Our precise surgical target was the Judeo-Christian power monolith, which has imposed a guilty, inhibited, grim, anti-body, anti-life repression on Western civilization.

Divorce: fission after fusion.

It has as much to do with the energy released by linguistic fission and fusion, with the buoyancy generated by cadence and tone and rhyme and stanza, as it has to do with the poem's concerns or the poet's truthfulness.

When all thermonuclear sources of energy are exhausted a sufficiently heavy star will collapse. Unless fission due to rotation, the radiation of mass, or the blowing off of mass by radiation, reduce the star's mass to the order of that of the sun, this contraction will continue indefinitely.

I must furnish those, who would protect or save life, with an energy source, which produces energy so cheaply that nuclear fission will not only be uneconomical, but ridiculous. This is the task I have set myself in what little life I have left.


Most of us do not understand nuclear fission, but we accept it.

I don't understand television, but I accept it. I don't understand radio, but every week my voice goes out around the world, and I accept it. Why is it so easy to accept all these man-made miracles and so difficult to accept the miracles of the Bible?

One-third of the world, it has been said, may be free- -but one-third is the victim of cruel repression--and the other one- third is rocked by the pangs of poverty, hunger and envy. More energy is released by the awakening of these new nations than by the fission of the atom itself.

When any government, or any church for that matter, undertakes to say to its subjects, This you may not read, this you must not see, this you are forbidden to know, the end result is tyranny and oppression, no matter how holy the motives. Mighty little force is needed to control a man whose mind has been hoodwinked; contrariwise, no amount of force can control a free man, a man whose mind is free. No, not the rack, not fission bombs, - not anything - you can't conquer a free man; the most you can do is kill him.

It is impossible, except for theologians, to conceive of a world-wide scandal or a universe-wide scandal; the proof of this is the way people have settled down to living with nuclear fission, radiation poisoning, hydrogen bombs, satellites, and space rockets.

The pace of science forces the pace of technique.

Theoretical physics forces atomic energy on us; the successful production of the fission bomb forces upon us the manufacture of the hydrogen bomb. We do not choose our problems, we do not choose our products; we are pushed, we are forced -- by what? By a system which has no purpose and goal transcending it, and which makes man its appendix.


My novels tend to come about from a fusion of two big ideas, creating a critical mass that then fissions, throwing off hundreds of other particles, riffs, tropes and characters.

We can and should complain about certain horrors of the modern world, but when it comes to the treatment of mental illness, the advances made in the last hundred years have been far more significant than the space program, nuclear fission, or even The Wire, for so many fortunate people.

Today, nothing is unusual about a scientific discovery's being followed soon after by a technical application: The discovery of electrons led to electronics; fission led to nuclear energy. But before the 1880's, science played almost no role in the advances of technology. For example, James Watt developed the first efficient steam engine long before science established the equivalence between mechanical heat and energy.
