The most all penetrating spirit before which will open the possibility of tilting not tables, but planets, is the spirit of free human inquiry. Belie….

There exists everywhere a medium in things, determined by equilibrium..

Knowing how contented, free, and joyful is life in the world of science, one fervently wishes that many would enter its portals..

When the elements are arranged in vertical columns according to increasing atomic weight, so that the horizontal lines contain analogous elements aga….

Work, look for peace and calm in work: You will find it nowhere else. Pleasures flit by -- they are only for yourself; work leaves a mark of long-las….

No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments..

There is nothing in this world that I fear to say..

No one nor anything can silence me..

I have achieved an inner freedom..

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

Certain characteristic properties of elements can be foretold from their atomic weights..

The establishment of a law, moreover, does not take place when the first thought of it takes form, or even when its significance is recognised, but o….

It is the function of science to discover the existence of a general reign of order in nature and to find the causes governing this order. And this r….

I have to talk like this! It`s my job.

If all the elements are arranged in the order of their atomic weights, a periodic repetition of properties is obtained. This is expressed by the law ….

The edifice of science not only requires material, but also a plan. Without the material, the plan alone is but a castle in the air-a mere possibilit….

Work, look for peace and calm in work: you will find it nowhere else..

I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper..

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

Why do they [Americans] quarrel, why do they hate Negroes, Indians, even Germans, why do they not have science and poetry commensurate with themselve….

The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compo….
