Sir Issac Newton is considered the last alchemist. he was one of the geniuses of the time, inventing calculus, revolutionizing optics, ending the age of alchemy. Newton was neurotic, had little social life, and never married. he did countless experiments, systematizing further alchemical ideas, and soundly disproving many of them with newfound analytical tools. He was, like Boyle, a mechanical philosopher. though his beliefs differed from Boyle’s views, they ultimately lead to Newtonian mechanics, the three laws of motion. it is not inaccurate to say that almost all of Newtons achievements where driven by his philosophical interest in alchemy.
