Physics

Physics is the science of matter, energy, space and time. It looks both inward and outward, from the smallest subatomic particle to the vastness of the universe—and yet it is also intensely practical. Physics begins with the everyday physical world around us—the blue of the sky, the colors of the rainbow, the fall of an apple, the motions of the moon. What's happening here? Why do things work this way?
