Study Notes
Modern Physics: Exploring the Subfields
Modern physics, the field that emerged in the 20th century, encompasses a wide array of subdisciplines, each delving into different aspects of our physical universe. Here, we'll explore three primary subfields: theoretical physics, experimental physics, and applied physics.
Theoretical Physics
Theorists, using mathematics and models, seek to explain current phenomena, predict new ones, and describe the laws of the universe. These researchers tackle specific problems, limited in scope, often involving complex equations and abstract concepts.
Experimental Physics
Experimentalists test theoretical predictions and investigate observable interactions and physical behavior. This subfield often leads theory, as when a new unpredicted particle is discovered. Experimental physicists construct and operate instruments, ranging from small equipment to massive installations like the Large Hadron Collider. Like theorists, they work to extend current knowledge of the physical world.
Applied Physics
Applied physicists solve practical problems by applying physics principles to real-world situations. This subdiscipline bridges the gap between physics and engineering. For example, medical physicists apply physics concepts to treat cancer patients with radiation, while others may develop technologies such as semiconductors or large-scale weather simulations.
Research Opportunities
Many undergraduate physics departments have limited research opportunities on campus. Students can expand their exposure to different fields by seeking opportunities outside their departments, such as national labs, private companies, or postgraduate institutions.
Modern Physics and Employment
The skills developed through modern physics research—problem-solving, data analysis, and creative thinking—are highly valuable in a variety of careers. Physicists are sought after by organizations that include colleges and universities, national labs, private companies, and hospitals. Moreover, the skills developed in modern physics research are often transferable to other fields, such as computer science, engineering, and finance.
Graduate Research Assistants
Graduate research assistants (GRAs) play a significant role in modern physics research. GRAs can gain valuable experience, such as the opportunity to collaborate with leading researchers, attend conferences, and present their work. Some GRAs may even have the opportunity to participate in international research collaborations, as Ahmad Nemer did in Japan.
Research Assistantships
Research assistantships are a valuable opportunity for students to gain hands-on research experience and develop skills that will serve them in modern physics and other fields. In these roles, students contribute to research projects under the guidance of faculty or senior researchers. Depending on their experience, students are paid as either training or research assistants, with pay rates increasing as they gain more experience.
Conclusion
Modern physics is a wide and exciting field, encompassing an array of subfields, research opportunities, and career paths. The skills developed in modern physics research are highly valuable in a variety of careers, making this field a worthwhile and engaging pursuit. Whether you're a curious undergraduate seeking a research assistantship or a graduate student seeking a career in a specific branch of modern physics, the opportunities and rewards are numerous.
