Antoine Lavoisier‚ deemed the father of modern chemistry‚ was born August 26‚ 1743 in Paris‚ France‚ but he did not pursue his love for science as a career until after he received a bachelor’s degree in law and obtained a license to practice law in 1764. Lavoisier always had a strong interest in the sciences‚ but was encouraged by his father to consider it only a hobby. However‚ in 1764‚ the same year he decided against practicing law‚ his first scientific paper was published‚ and he was elected

What is Brain Chemistry? Brain chemistry or neurochemistry is the complex system which allows the brain to function with the use of chemicals known as neurotransmitters which move information around in the brain. Every person’s brain chemistry is slightly different‚ and a number of things can play a role in the levels of various neurotransmitters in the brain‚ and how those chemicals affect the brain’s function. It is believed that difference in brain chemistry may explain a variety of behavioral

the first to state this‚ but this is false. The first to state this was actually Jean Ray who had come up with a similar law. This law only became established after Lavoisier discovered it. Lavoisier produced his book Elementary Treatise on Chemistry. In this book he states the difference between a compound and an element‚ since so many people did not know the difference. This book also included the idea that light was a chemical element. He also stated in his book that there was a substance
