Revision of the SI: International System of Units
This lecture covers the revision of the International System of Units (SI), focusing on the kilogram, ampere, kelvin, and mole. The SI, based on fundamental constants, is being updated to ensure global comparability of measurements. Historical context, such as the metric system's evolution, is discussed, along with the new definitions and the impact on scientific measurements. The presentation also explores the Kibble balance and Avogadro project as alternative approaches to redefine the SI units.
