Alchemy is an idea based on superstition and philosophical global traditions spanning hundreds of years. Alchemists made medicines and pharmaceuticals from the earth’s materials and purified objects through philosophy, magic, and spirituality. Chemistry is based on the material principles of mixed bodies, and spans all natural or physical sciences in its practices. This book on alchemy and chemistry shows the scientific method at work and proves and disproves the subjects at hand. It explores a branch of modern science or a major scientific milestone, comparing and contrasting it with an older idea that has been proved wrong or fails to meet the strict and studied standards of science.
