A Quote by 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.

[This] may prove to be the beginning of some embracing generalization, which will throw light, not only on radioactive processes, but on elements in general and the Periodic Law.... Chemical homogeneity is no longer a guarantee that any supposed element is not a mixture of several of different atomic weights, or that any atomic weight is not merely a mean number.

Frederick Soddy

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

Dmitri Mendeleev

Probably our atomic weights merely represent a mean value around which the actual atomic weights of the atoms vary within certain narrow limits... when we say, the atomic weight of, for instance, calcium is 40, we really express the fact that, while the majority of calcium atoms have an actual atomic weight of 40, there are not but a few which are represented by 39 or 41, a less number by 38 or 42, and so on.

William Crookes

It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.

Francis William Aston

Extrapolated, technology wants what life wants: Increasing efficiency Increasing opportunity Increasing emergence Increasing complexity Increasing diversity Increasing specialization Increasing ubiquity Increasing freedom Increasing mutualism Increasing beauty Increasing sentience Increasing structure Increasing evolvability

A Christian man is on his guard with respect to those who philosophize according to the elements of this world, not according to God, by Whom the world itself was made; for he is warned by the precept of the apostle and faithfully hears what has been said, 'Beware that no one deceive you through philosophy and vain deceit, according to the elements of the world'

Saint Augustine

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

On the geometric level, we see certain physical elements repeated endlessly, combined in an almost endless variety of combinations. It is puzzling to realize that the elements, which seem like elementary building blocks, keep varying, and are different every time that they occur. If the elements are different every time that they occur, evidently then, it cannot be the elements themselves which are repeating in a building or town; these so-called elements cannot be the ultimate "atomic" constituents of space.

Christopher Alexander

Experimental work of great refinement is necessary in order to determine atomic weights. No relationships between them have yet been certainly found which make it possible for us to compute by any sort of calculation exactly the value of any one atomic weight from any other.

Theodore William Richards

And as particles are living digital elements, moving on their own according to the various attributes (such as weight, speed, shape) given to them by the animator, we don't know what the visual result will be until everything is completed. This result can often be unsatisfying, obliging us to repeat the process all over again, with new features.

Martine Epoque

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

Dmitri Mendeleev

Why should a man have any apprehension about the change and dissolution of all the elements? For it is according to nature, and nothing is evil which is according to nature.

Marcus Aurelius

The problem is the following, black music is increasing encumbered by white elements, often pleasant but always superfluous, easily and advantageously replaced with black elements.

Boris Vian

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

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