Dmitri Mendeleev Quotes & Sayings

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 only when it has been confirmed by the results of the experiment. — Dmitri Mendeleev

We could live at the present day without a Plato, but a double number of Newtons is required to discover the secrets of nature, and to bring life into harmony with the laws of nature. — Dmitri Mendeleev

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

Pleasures flit by - they are only for yourself; work leaves a mark of long-lasting joy, work is for others. — Dmitri Mendeleev

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 of periodicity. — Dmitri Mendeleev

The most all penetrating spirit before which will open the possibility of tilting not tables, but planets, is the spirit of free human inquiry. Believe only in that. — Dmitri Mendeleev

Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs). — Dmitri Mendeleev

I want you to have this feeling too - it is my moral responsibility to help you achieve this inner freedom. — Dmitri Mendeleev

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

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

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

No one nor anything can silence me. — Dmitri Mendeleev

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

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

When the elements are arranged in vertical columns according to increasing atomic weight, so that the horizontal lines contain analogous elements again according to increasing atomic weight, an arrangement results from which several general conclusions may be drawn. — Dmitri Mendeleev

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

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

I have achieved an inner freedom. — Dmitri Mendeleev

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

Why do they [Americans] quarrel, why do they hate Negroes, Indians, even Germans, why do they not have science and poetry commensurate with themselves, why are there so many frauds and so much nonsense? I cannot soon give a solution to these questions ... It was clear that in the United States there was a development not of the best, but of the middle and worst sides of European civilization; the notorious general voting, the tendency to politics ... all the same as in Europe. A new dawn is not to be seen on this side of the ocean. — Dmitri Mendeleev

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

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. — Dmitri Mendeleev

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 refers in equal measure to the relations of man - social and political - and to the entire universe as a whole. — Dmitri Mendeleev

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 possibility; whilst the material without a plan is but useless matter. — Dmitri Mendeleev
