What Does a Physicist Do?

A physicist asks fundamental questions about the interaction between matter and energy and then begins observation and experimentation to answer these questions. Many of the technological advances that humans have today are the results of a physicist's work.

Physicists perform a wide variety of roles in the workforce. Careers can range from sustainable energy production to designing and developing video games. The medical field also relies on physicists to help develop better cancer-fighting treatments and improving the diagnosis of illnesses. The computers that are used for imaging utilize advances that physicists helped develop.

Physicists depend on an understanding of different mathematical models and relationships and rely on them for creating the different theories that they then test. Physicists focus their foundation of learning on the natural world around them. This base allows physicists the possibility to test theories and draw conclusions based on actual data.

Physicists rely on computers to help build modelling processes that are complex. This helps give physicists the knowledge to help answer some of the fundamental questions a physicist asks in regard to how the universe works and how it may continue to change. Nearly all aspects of modern life are influenced by the work of physicists.
