Dmitri Mendeleev Quotes.
Certain characteristic properties of elements can be foretold from their atomic weights.
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.
No one nor anything can silence me.
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.
The elements which are the most widely diffused have small atomic weights.
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?
The elements, if arranged according to their atomic weights, exhibit an apparent periodicity of properties.
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.
Work, look for peace and calm in work: you will find it nowhere else.
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.
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.
There is nothing in this world that I fear to say.
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.
There exists everywhere a medium in things, determined by equilibrium.
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).
I want you to have this feeling too – it is my moral responsibility to help you achieve this inner freedom.
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-lasting joy, work is for others.
I have to talk like this! It`s my job
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.
No law of nature, however general, has been established all at once; its recognition has always been preceded by many presentiments.
