Program Summary
Physics and Astronomy are for creative and curiously-minded students who want a shot at cracking Nature's secret source code — people who are excited by questions like “What happened right after the Big Bang?”, “How does time warp near a black hole?”, or “Can atomic systems coexist in multiple realities at once?”
Physics and Astronomy are for inventive and enterprising students who want to design humanity's future — people who are motivated by questions like "Can clean fusion energy propel equitable access to technology and resources?", "How will quantum computing revolutionize our link with information?", or "When will self-sustaining communities be established on Mars?"
Physicists work to understand the most basic laws of nature in the most simple and general way possible. Physicists likewise apply this understanding to solving engineering and design problems in every facet of modern life. Our faculty specialize in Materials Science (exploring properties of dense atomic systems computationally and with x-ray / atomic-force imaging, and designing superior molecular compounds for engineering applications like batteries and superconductors) and Particle Physics (theory and high-performance computer simulation involving elementary constituents of matter and their interactions, the Large Hadron Collider in Switzerland, the search for dark matter, and mysterious properties of the neutrino).
Astronomers seek to understand our place in the Universe, and to unravel clues about its history from light reaching us across the expanse of space. Our faculty take a special interest in the data-based improvement of approaches to science education, and have research expertise in the topics of stellar spectroscopy and ionized gas in spiral galaxies. The university observatory houses several telescopes for in-person stargazing, and our indoor planetarium provides immersive simulations of the night sky as viewed from any location and date.
Academic Programs
The department offers a Bachelor of Science degree in Physics plus several options for Pre-Engineering. Physics and Engineering go together very well, because so much of Engineering Design is built upon the underlying foundation of Physics.
Pre-Engineering includes more Math (especially Calculus) than Engineering Technology does, and it leads to very different careers. The Accreditation Board for Engineering and Technology (ABET) says that Engineering programs often focus on theory and conceptual design, while Technology programs usually focus on application and implementation. Engineers often do work involving original research and development, and many continue on to Masters or Doctoral programs in Engineering. Technologists are most likely to work in construction, manufacturing, product design, testing, or technical services and sales.
In the Dual Degree, or "3+2" program, students earn degrees in both Physics and Engineering. This starts with three years at SHSU, completing the Core Curriculum, the Calculus and Physics introductory sequence, and a portion of the upper division Physics Curriculum. Students then apply to any accredited Engineering program at an institution of their choice for the last two years of degree work. One option is UT Tyler, where a transfer agreement guarantees admission for students with a 2.5 GPA. After completion of the Engineering Degree, credits are retroactively transferred back to SHSU so that the Physics Degree can be awarded simultaneously.
The "2+2" Pre-Engineering Tracks in Civil, Mechanical, and Electrical Engineering are four-year degrees where students transfer to an accredited Engineering Program (such as UT Tyler) after completing two years at SHSU.
The Bachelor of Science degree in Physical Science with Secondary Certification is available to students seeking careers in secondary education.
The Minor in Physics pairs well with other Science, Technology, Engineering, and Mathematics (STEM) majors. It also complements a number of cross-over careers such as Science Journalism, and K-12 Science Education.
Career Opportunities
A degree in Physics or Pre-Engineering leads to many profitable career options because it develops marketable attributes and skills that employers are greatly interested in. This includes mental flexibility, capacity for critical though, abstraction and generalization, training in creative problem solving, intuition for mechanical and electrical systems, and proficiency in advanced mathematics, data analysis, and computer applications (including programming).
According to the American Institute of Physics (AIP), across the country, 95% of Physics Bachelors are either employed or enrolled in graduate school one year after graduation. PhD students in physics and astronomy usually receive a full tuition waiver plus a substantial wage or stipend. In the private sector, about 35% of graduates do engineering, 25% do computing or information, and 15% take other STEM-related jobs, all with competitive starting salaries. A shortage of high-school physics instructors means that plenty of attractive and well-paid teaching positions are currently accepting applications across the state.
Program Specific Information
Sam Houston State University is a wonderful place to study Physics, Astronomy, and Pre-Engineering. We provide an outstanding educational environment, with small class sizes, extensive personalized attention, and expert instruction. Our students build strong resumes with hands-on faculty-directed research experiences (in topics such as Particle Physics, Materials Science, and Astronomy Education), and have the option to work as paid assistants for introductory laboratory sessions. Most of our students receive scholarship assistance directly from the department and its donors, in amounts up to $5,000 per year for outstanding candidates.
All students interested in Physics or Pre-Engineering enroll in the Physics Bootcamp (PHYS 1401) during their first semester on campus. This lets interested students see what physics is all about as early as possible, with no prerequisites. It ensures that they have math skills required in the next two years, and helps them understand what those skills are good for in Physics and Engineering. It develops confidence, teamwork, camaraderie, and a sense of belonging in the department. A weekly group-based problem-solving practice session is integrated. The Bootcamp is typically offered each Fall and Spring term.
