What is a theoretical physicist?
A theoretical physicist is a scientist who uses mathematics, calculations, chemistry, biology and a series of theories to understand the complex workings of the universe and the interactions between matter and energy. They often attempt to understand areas that scientists are not currently capable of traveling to for exploration and data collection, such as the deep reaches of outer space and the ocean floor. Some of the most common theories studied by theoretical physicists include:
What does a theoretical physicist do?
The responsibilities of theoretical physicists vary greatly. However, they often conduct research and develop calculations for a wide variety of theories and concepts. Unlike other fields of physics, theoretical physicists spend little or no time conducting physical experiments. Instead, they devote most of their efforts toward developing theories through mathematical calculation and field research in an attempt to expand knowledge in the scientific community and contribute to the advancement of society.
Common duties of theoretical physicists may be to:
Conduct research on physical phenomena using computers and data analysis
Develop theories based on observations and calculations
Create methods to apply physical laws and theories
Develop and refine existing theories using calculations
Discuss equations, formulas, problems and ideas with colleagues and other scientists
Contribute to academic studies and published peer-reviewed articles
Write computer software to assist in the development of theories and aid in research
Study currently accepted theories in the field
Perform mathematical calculations in an attempt to prove abstract theories
Teach advanced theories and practices to physics students
Design scientific equipment for advancement of research
Conduct research related to potential environmental impacts of nuclear and atomic activity
Develop manufacturing and assembly procedures using lasers, infrared and light-sensitive devices
Advise government bodies and officials on best practices during an atomic or nuclear event

Observe the structure and properties of matter
Assist in civil defense planning in the event of chemical hazards
Theoretical physicist work environment
Typically, theoretical physicists work in office, laboratory or academic settings. These individuals may work at universities, laboratories, development facilities or government agencies. Work weeks for theoretical physicists are typically 40 hours and take place during regular business hours, though some overtime is possible depending on workload. Sometimes travel may be necessary for events such as conferences, meetings, seminars and expeditions.
Benefits of being a theoretical physicist
There are several benefits and rewarding aspects of being a theoretical physicist, including:
Contributing to the scientific community
Theoretical physicists make important contributions to the advancement of our communities by furthering our understanding of nature and the complex relationship between matter and energy. The individuals working in this field have the opportunity to provide valuable knowledge and advancement to several types of industries, including:
Technology and engineering
Medicine and healthcare technologies
Exploring the mysteries of the universe
