Physics is crucial to understanding the world around us, the world inside us, and the world beyond us. It is the most basic and fundamental science. Physics challenges our imaginations with concepts like relativity and string theory, and it leads to great discoveries, like computers and lasers, that lead to technologies which change our lives—from healing joints, to curing cancer, to developing sustainable energy solutions. Physics encompasses the study of the universe from the largest galaxies to the smallest subatomic particles. Moreover, it’s the basis of many other sciences and is essential for those interested in careers such as engineering and architecture.
