几个世纪以来，物理学家和天文学家研究了控制物理世界中物质和能量从亚原子粒子到宇宙的结构和动力学的原理。物理学家寻求通过实验，理论和计算方法，在声学，天文学，原子和分子物理学，生物物理学，凝聚态物理学，宇宙学，医学物理学，纳米技术，核物理，光学，粒子物理学，等离子体物理学，量子力学，相对论和热力学。物理学家还将这种理解应用于新技术的发展。例如，物理学家发明了第一批激光器，半导体电子设备和立体声。物理学和天文学的学生从力学，电和磁，统计和热物理学，量子力学，相对论，光学和声学的广泛背景中学习解决复杂的科学技术
Over the centuries physicists and astronomers have studied the principles that govern the structure and dynamics of matter and energy in the physical world, from subatomic particles to the cosmos. Physicists seek to expand human knowledge through experiment, theory, and computational methods, in fundamental areas such as acoustics, astronomy, atomic and molecular physics, biophysics, condensed matter physics, cosmology, medical physics, nanotechnology, nuclear physics, optics, particle physics, plasma physics, quantum mechanics, relativity, and thermodynamics. Physicists also apply this understanding to the development of new technologies. For example, physicists invented the first lasers, semiconductor electronic devices, and stereo sound. Physics and astronomy students learn to approach complex problems in science and technology from a broad background in mechanics, electricity and magnetism, statistical and thermal physics, quantum mechanics, relativity, optics, and acoustics. The tools they develop at BYU include problem solving by mathematical and computational modeling, as well as experimental and observational discovery and analysis. All students gain professional experience via a research senior thesis, capstone project, internship project, or student teaching, usually in close association with a faculty member. Together these experiences can provide excellent preparation for employment or for graduate studies in physics, other sciences, engineering, medicine, law, or business. Most physicists and astronomers work in research and development in industrial, government, or university labs to solve new problems in technology and science. They also share the beauty discovered in our physical universe by teaching in planetariums, high schools, colleges, and universities.<br><br>This program meets the educational requirements designed to lead to an occupationally required professional license or certificate in the state of Utah. Students pursuing occupations requiring a license or certificate in a state other than Utah should contact the appropriate BYU academic advisement center as well as the licensing agency in the state where they intend to work to seek information and guidance regarding licensure and certification requirements.<br>This major is designed to prepare students to teach in public schools. In order to graduate with this major, students are required to complete Utah State Office of Education licensing requirements.
