One of the best-known Physicists of our lifetime is Albert Einstein, the scientist whose theories changed the way we think about the universe. Physicists today spend their days producing design and research for experimental or theoretical physics as he did.  
  
The practice of physics is broad, meaning that there are many ways to approach the discipline. Tasks for this profession involve heavy analysis to interpret the research data and results while also developing mathematical models and simulations to explain the behavior of matter and energy. Physicists will also need to document their findings carefully, involving data entry or other administrative tasks.  
  
This career isn't always for the introvert, as the reputation for science often portrays. Career Physicists can be engaging, often liaising and collaborating with others in their field to develop new methods and further expand the boundaries of science. Such partnerships can further develop innovative technologies and equipment for research, commercial, or military purposes. They may also advise and counsel government authorities on radioactive materials and their impact on the environment.  

Roles and responsibilities of a Physicist
Here’s a non-exhaustive list of everyday tasks Physicists are required to complete.  

• Observing the behavior and properties of matter and the transformation and propagation of energy.  
• Using specialized equipment (e.g., lasers, masers, spectrometers, and telescopes) to identify the fundamental principles governing phenomena.  
• Performing complex calculations as part of data analysis and evaluation.  
• Documenting observations and conclusions in mathematical terms.  
• Developing theories and laws to explain the behavior of matter and energy based on observations and experiments.  
• Designing mathematical models and computer simulations to mimic and explain phenomena.  
• Reporting experimental results by publishing papers in scientific journals and presenting findings and developments in scientific conferences.  
• Expanding the boundaries of scientific achievements and knowledge.  
• Contributing to the scientific community.  
• Liaising with colleagues and other scientists in the design and development of new scientific equipment and experiments.  
• Teaching Physics to undergraduate and graduate students. 
• Tutoring students pursuing bachelor’s, master’s, and doctoral degrees in Physics and any of its subcategories.  
• Developing and manufacturing specialized scientific and technological equipment for research, commercial, medical, industrial, or military purposes in collaboration with colleagues and Engineers.  
• Designing lasers, masers, infrared, and other light-sensitive and light-emitting devices.  
• Collaborating with other Scientists and specialists to test new equipment.  
• Conducting application evaluations to determine the uses of modern technologies.  
• Working with and handling radioactive materials and atomic energy-related facilities and equipment.  
• Testing and monitoring levels of radioactive contamination of equipment and laboratory personnel.  
• Recording and tracking levels of radioactive exposure of personnel to avoid health and safety hazards.  
• Determining standards of permissible concentrations of radioactive isotopes, liquids, and gases.  
• Establishing safety protocols and procedures  
• Researching the environmental impact of radioactive activity, the atomic energy industry, and other industrial activities.  
• Advising and counseling government authorities on safety procedures regarding radiation incidents and activities.
