Metrology is the framework behind modern science and technology. For most of us, our first experience with metrology might have been counting fingers and toes. But how do you measure the oscillations of a beam of light—the fastest thing in the universe? This talk will tell you about new metrology tools that are used to count the cycles of a wave of light and how that is being used to build ultraprecise optical atomic clocks. Interestingly, the same light measurement tools are also being applied to quantify the composition of the air we breathe and find exoplanets around nearby stars.
