Physicists are the perpetual three year olds of science. They always ask: Why? Physics is about observing nature, from elementary particles to the entire universe, and wondering why and how it works.
While enjoying the beauty of natural phenomena such as rainbows or dark star filled skies, physicists continue trying to understand how they work. Achieving this understanding enhances nature's beauty. The best physicists keep their childlike wonder while unraveling nature's mysteries.
As Whitman's Learned Astronomer, they show "the charts and the diagrams, to add, divide and measure them" while continuing to wander off "in the mystical moist night-air, and from time to time [look] up in perfect silence at the stars"
