The whole art of making experiments in chemistry is founded on the principle: we must always suppose an exact equality or equation… — Antoine Lavoisier Copy Share Image
We must trust to nothing but facts: These are presented to us by Nature, and cannot deceive. We ought, in every instance,… — Antoine Lavoisier Copy Share Image
We may lay it down as an incontestible axiom, that, in all the operations of art and nature, nothing is created; an… — Antoine Lavoisier Copy Share Image
The art of drawing conclusions from experiments and observations consists in evaluating probabilities and in estimating whether they are sufficiently great or… — Antoine Lavoisier Copy Share Image
The impossibility of separating the nomenclature of a science from the science itself, is owing to this, that every branch of physical science must… — Antoine Lavoisier Copy Share Image
I consider nature a vast chemical laboratory in which all kinds of composition and decompositions are formed. — Antoine Lavoisier Copy Share Image
Perhaps... some day the precision of the data will be brought so far that the mathematician will be able to calculate at his desk… — Antoine Lavoisier Copy Share Image
Experiments upon vegetation give reason to believe that light combines with certain parts of vegetables, and that the green of their leaves, and the… — Antoine Lavoisier Copy Share Image
“About eight days ago I discovered that sulfur in burning, far from losing weight, on the contrary, gains it; it is the same with… — Antoine Lavoisier Copy Share Image
It required 85 parts by weight of oxygen and 15 parts of hydrogen to compose 100 parts of water. — Antoine Lavoisier Copy Share Image
It is impossible to disassociate language from science...To call forth a concept, a word is needed. — Antoine Lavoisier Copy Share Image
Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of… — Antoine Lavoisier Copy Share Image
Since it is the very substance of the animal, it is the blood which transports the fuel.If the animal did not habitually replace, through… — Antoine Lavoisier Copy Share Image
If everything in chemistry is explained in a satisfactory manner without the help of phlogiston, it is by that reason alone infinitely probable that… — Antoine Lavoisier Copy Share Image
In performing experiments, it is necessary... that they be simplified as much as possible, and that every circumstance that could complicate the results should… — Antoine Lavoisier Copy Share Image
