E = mc2 for the Chemist: When Is Mass Conserved? Richard S. Treptow
Einstein's famous equation is frequently misunderstood in textbooks and popular science literature. Its correct interpretation is that mass and energy are different measures of a single quantity known as massenergy, which is conserved in all processes.
