What is a Physicist?

Physics is the study of the forces and laws of nature, from the largest galaxies to the tiniest subatomic particles. It's the most fundamental science, since the laws of nature determine everything else, forming the basis of chemistry, and ultimately of biology, organisms, and ecosystems. It also encompasses electricity and magnetism. Advances in these and other areas of physics have made electric power, industry, electronic devices, and our modern standard of living possible.

A physicist is an inquisitive person who spends his or her life trying to advance our knowledge of how things work. Theoretical physicists study things like the relationships between matter and energy and the nature of the universe, usually through advanced mathematical equations. Applied physicists try to put that knowledge to practical use by inventing new products and processes.

What Does a Physicist Do?

Physicists study the forces, laws, and behavior of nature to understand how things work, or to develop new materials, electronics, processes, or energy sources. Physics is a broad field with many areas of specialization, including environmental physics.

Environmental physicists apply physical principles to environmental problems. They work on creating new materials, photovoltaic systems, and products that are better for the environment. They also work on remote sensing equipment, energy conservation measures, atmospheric models, and other issues related to the environment. Environmental physicists may find careers in remote sensing, atmospheric climate modeling, pollution control, energy conservation, renewable energy development, nuclear waste disposal, and site remediation. Condensed matter physicists who study the condensed states of matter (liquids and solids) are involved in materials research, and are especially important to the development of photovoltaic systems. Some plasma physicists study ways to create fusion reactors to power our society.

Geophysicists use seismic waves to find out what's underground. While they often do this for oil companies, they also investigate potential or existing landfill sites, and provide seismological data to governments. Geophysicists also work on geothermal energy systems, converting the earth's heat energy to clean, renewable electric power. Geothermal energy is a rapidly expanding field in many countries.

Regardless of specialty, most physicists do many of the same things, like use complex calculations and computer models to analyze data. They use math to describe theories and processes. They may observe, identify and measure physical phenomena with lasers, telescopes, and other advanced equipment. They share their research results by writing papers and presenting at conferences.

Many people with advanced physics degrees teach and do research as faculty members at colleges and universities. Those with undergraduate degrees may become high school science teachers.

Where Does a Physicist Work?

As of 2012, most (29%) physicists worked in research and development in the physical, engineering, and life sciences. Colleges and universities were the next highest employers of physicists (19%). 16% worked for the federal government, and 7% were employed in management, scientific, and technical consulting services. 5% were medical physicists employed by hospitals.

The National Aeronautics and Space Administration (NASA) and the U.S. Department of Defense are two of the largest employers of physicists and astronomers in the federal government. However, aspiring geophysicists interested in geothermal energy should note that Canada, Iceland, Italy, Japan and New Zealand are the leaders in geothermal development. The industry is also rapidly growing in the U.S. and Scandinavia.

Physicists spend most of their time in laboratories and offices. Most physicists and astronomers work full time.

What Is the Average Physicist Salary?

According to the U.S. Bureau of Labor Statistics (BLS), the median annual wage for physicists was $106,840 in May 2012. Those working for hospitals made the most money ($152,280). Physicists employed in management, scientific, and technical consulting services earned $130,980. Those in the federal government earned $111,020, and those employed in research and development in the physical, engineering,and life sciences made $104,650. Physicists working for colleges, universities and professional schools earned $81,180.

What Is the Job Demand for Physicists?

Employment of physicists and astronomers is projected to grow 10 percent from 2012 to 2022, about as fast as the average for all occupations. While growth in physics research dependent on government funding is expected to be flat, grants for energy and advanced manufacturing research will continue the need for physicists. Physicists will also be needed in a wide range of industries in the private sector. Nuclear energy, renewable energy, and environmental jobs are areas of job growth.

How Do I Get a Physics Degree?

Doctoral degrees are required for most jobs, though master's degrees (M.S.) are sufficient for many applied research and development positions in industry. Graduates with bachelor's degrees in physics (B.S.) who don't want to earn an advanced degree may be qualified for jobs as technicians and assistants in related fields like engineering or computer science.

Undergraduate programs focus on the natural sciences and math. Core courses in physics include quantum mechanics (the study of the very small, i.e., subatomic level), electromagnetism, thermodynamics, and optics. Chemistry and calculus are also covered. Computer science is also very important, since computer modeling is an integral part of physics. Aspiring environmental physicists may also study condensed matter physics, electronics, ecology, environmental assessment, and biology.
Some sensitive federal government positions may only accept as candidates U.S. citizens with security clearances.
