Nobel Laureate Dr. William D. Phillips on Why We Measure

World-renowned physicist Dr. William D. Phillips talks about how measurements became standard around the world. Physics relies on standardized units of measurement to ensure consistency and comparability of results. The International System of Units (SI) is the standard system used in physics, which includes units like meters for length, kilograms for mass, seconds for time, and others. Measurement in physics is not just about assigning numbers to physical quantities; it's about extracting meaningful information from the natural world and refining our understanding of the underlying principles that govern it. The precision and accuracy of measurements in physics are critical for developing and testing scientific theories. www.montgomerycollege.edu/events/nobel-laureate www.nist.gov
