Why humans need units and proportions to understand the universe
In short: From subatomic particles to cosmic timelines, our senses cannot perceive the true scale of reality. This video explores how scientists use specific tools of proportion and measurement to make the invisible visible.
Paul Andersen explains that the universe operates across three primary scales: size, timespan, and energy. Because many natural phenomena occur at speeds too fast or sizes too small—or are conversely too large and slow—for human observation, we rely on units of measure to bridge the gap.
The video highlights how understanding proportion is essential for both science and engineering. By mastering these concepts, we can comprehend complex systems that exist far outside our immediate physical experience.
