The 24+ Dmitri Mendeleev Quotes

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.

I Have To Talk Like This! It`s My Job

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.

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.

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.

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).

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.

The Elements Which Are The Most Widely Diffused Have Small Atomic Weights.

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.

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 Law Of Nature, However General, Has Been Established All At Once; Its Recognition Has Always Been Preceded By Many Presentiments.
