The Physical Universe
"It has to do with curiosity. It has to do with people wondering what makes something do something. And then to discover, if you try to get answers, that they are related to each other–that things that make the wind make the waves, that the motion of water is like the motion of air is like the motion of sand. The fact that things have common features. It turns out more and more universal. What we are looking for is how everything works. What makes everything work."— Richard Feynman
People of every culture have pondered their origins and the origins of the cosmos. What is this space around us? Where did the matter that makes up the world around us come from? These questions remain some of the most pressing in science. They are a testament to our curiosity from childhood on and the work needed to expand the present limits of our knowledge.
