Lavoisier made important discoveries in the world of science.  However, his discoveries were not only essential for scientific progress, but also form the basis of how experiments are analysed and conducted today.  Lavoisier attached a great deal of importance to precision and the emphasis of his success is on his ability to recognise the importance of qualitative observations.

Thus Lavoisier was able to demonstrate the faults in 'Aristotle's Four Elements'.  His theories, however, were not readily accepted by scientists at the time.  His new ideas questioned the fundamentals of Chemistry, as they were at the time.  Lavoisier's new theory about Phlogiston was labeled the 'Anti-Phlogiston' theory:  the methods he used to conduct his experiments did not conform to the traditional methods and were strongly opposed.

Lavoisier had to confront a large amount of opposition when he tried to publish a book on his work, however, thanks to his wealth, he was able to do so.

Lavoisier is known today as the Father of Modern Chemistry and many discoveries were made thanks to his work, which has allowed progress in the world of science.
