The elements which are the most widely diffused have small atomic weights.
Dmitri Mendeleev

The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties.
Dmitri Mendeleev

The future of the world, dependent as it is upon atomic energy, requires more understanding and knowledge about the atom.
Willard Libby

The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.
Dmitri Mendeleev

The mathematical framework of quantum theory has passed countless successful tests and is now universally accepted as a consistent and accurate description of all atomic phenomena.
Erwin Schrodinger

The most common and most important result of them is that the nature and size of the effect on corresponding series of different elements are largely an expression of the peculiarity of their atomic structure - or, at least, of the structure of the surface.
Johannes Stark

The only use for an atomic bomb is to keep somebody else from using one.
George Wald

The particular features of the photographic method of detecting atomic particles enabled us to establish the existence of transient forms of matter which had escaped recognition by other methods.
Cecil Frank Powell

The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one.
Albert Einstein

The use of the atomic bomb, with its indiscriminate killing of women and children, revolts my soul.
Herbert Hoover

The way to win an atomic war is to make certain it never starts.
Omar N. Bradley

There are relatively few experiments in atomic physics these days that don't involve the use of a laser.
Eric Allin Cornell

These studies resulted eventually in a complete sequence analysis of the complex from several species, and in the atomic resolution structure of the F catalytic domain of the enzyme from bovine mitochondria, giving new insights into how ATP is made in the biological world.
John E. Walker

Thus at the beginning of 1906 it seemed to be established that the emitters of the spectral series of chemical elements are their positive atomic ions.
Johannes Stark

We can in fact first place the beam of rays of moving positive atomic ions in a plane perpendicular to the axis in which we see the spectral lines emitted by them.
Johannes Stark

We had news this morning of another successful atomic bomb being dropped on Nagasaki. These two heavy blows have fallen in quick succession upon the Japanese and there will be quite a little space before we intend to drop another.
Henry L. Stimson

We must expect the discovery of many as yet unknown elements-for example, elements analogous to aluminum and silicon- whose atomic weight would be between 65 and 75.
Dmitri Mendeleev

When you see something that is technically sweet, you go ahead and do it and you argue about what to do about it only after you have had your technical success. That is the way it was with the atomic bomb.
J. Robert Oppenheimer

World War II, the atomic bomb, the Cold War, made it hard for Americans to continue their optimism.
Stephen Ambrose
