Nothing is lost, nothing is created, everything is transformed.
ANTOINE LAVOISIERNothing is lost, nothing is created, everything is transformed.
ANTOINE LAVOISIERThe whole art of making experiments in chemistry is founded on the principle: we must always suppose an exact equality or equation between the principles of the body examined and those of the products of its analysis.
ANTOINE LAVOISIERSulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed.
ANTOINE LAVOISIERNothing is born, nothing dies.
ANTOINE LAVOISIERPerhaps; some day the precision of the data will be brought so far that the mathematician will be able to calculate at his desk the outcome of any chemical combination, in the same way, so to speak, as he calculates the motions of celestial bodies.
ANTOINE LAVOISIERMathematicians come to the solution of a problem by the simple arrangement of the data, and reducing the reasoning to such simple operations, to judgments so brief, that they never lose sight of the evidence that serves as their guide.
ANTOINE LAVOISIERThus, while I thought myself employed only in forming a Nomenclature, and while I proposed to myself nothing more than to improve the chemical language, my work transformed itself by degrees, without my being able to prevent it, into a treatise upon the Elements of Chemistry.
ANTOINE LAVOISIERI am young and avid for glory.
ANTOINE LAVOISIERIt is impossible to disassociate language from science, To call forth a concept, a word is needed.
ANTOINE LAVOISIERThis theory [the oxygen theory] is not as I have heard it described, that of the French chemists, it is mine (elle est la mienne); it is a property which I claim from my contemporaries and from posterity.
ANTOINE LAVOISIERIt is almost possible to predict one or two days in advance, within a rather broad range of probability, what the weather is going to be; it is even thought that it will not be impossible to publish daily forecasts, which would be very useful to soci.
ANTOINE LAVOISIERExperiments upon vegetation give reason to believe that light combines with certain parts of vegetables, and that the green of their leaves, and the various colors of flowers, is chiefly owing to this combination.
ANTOINE LAVOISIERIn performing experiments, it is necessary… that they be simplified as much as possible, and that every circumstance that could complicate the results should be completely removed.
ANTOINE LAVOISIERImagination, on the contrary, which is ever wandering beyond the bounds of truth, joined to self-love and that self-confidence we are so apt to indulge, prompt us to draw conclusions which are not immediately derived from facts.
ANTOINE LAVOISIERA wealthy landowner cannot cultivate and improve his farm without spreading comfort and well-being around him. Rich and abundant crops, a numerous population and a prosperous countryside are the rewards for his efforts.
ANTOINE LAVOISIERThe art of drawing conclusions from experiments and observations consists in evaluating probabilities and in estimating whether they are sufficiently great or numerous enough to constitute proofs. This kind of calculation is more complicated and more difficult than it is commonly thought to be.
