Physics is the study of the most basic natural phenomena—from the smallest particles to the largest structures of the universe, from the beginning to the end. Physics is also the scaffolding behind the technology found in numerous current advances such as in smart phones, self-driving cars and radiation treatment of cancer. Physicists are keen to understand the nature of the world around them, as well as to control it for the betterment of humanity. They use their creativity to solve challenging problems, whether they are creating very powerful lasers for eye surgery, colliding particles at very-high energy, or descending deep down into underground mines to investigate the most basic building blocks of matter. Physicists look for and examine patterns in nature in order to formulate natural laws. They push scientific boundaries by exploring unknown territory through theory and experimentation, often thinking about and describing our physical world in ways that we cannot yet observe in nature.
