Finding an outdated physics textbook that still defines the kilogram using Le Grand K is like discovering someone using a flip phone in 2024! For the uninitiated, Le Grand K was a literal platinum-iridium cylinder kept in a vault in France that defined THE EXACT MASS of one kilogram for over 130 years. In 2019, scientists finally replaced this physical object with a definition based on Planck's constant. Talk about a weight being lifted off that cylinder's shoulders! Now it can retire in peace while modern physics textbooks catch up... eventually... maybe... hopefully?
