5 of the Best Measurements In Science

The video discusses the extensive testing of the Standard Model, comparing it to the predictability of sunrises. It highlights advancements in atomic clocks, particularly cesium and strontium, and their role in verifying general relativity. The equivalence of inertial and gravitational mass is explored through historical and modern experiments, including the MICROSCOPE satellite. The video also covers the precision of the Rydberg constant and electron g-factor, emphasizing their importance in scientific measurements. Finally, it addresses the near-perfect charge equivalence of protons and electrons, underscoring the quest for precision in understanding the universe.
