"...for nothing is created in the operations of either art or of nature, and it can be taken as an axiom that every operation an equal quantity of matter exists both before and after the operation, that the quality and quantity of the principles remain the same and that only changes or modifications occur. The whole art of making experiments in chemistry is founded on this principle: we must always suppose an exact equality or equation between the principles of the body examined and those of the products of it's analysis." -Antoine Lavoisier
