Applied Physics

The Bachelor of Science in Applied Physics at the California Institute of Technology offers a rigorous and comprehensive curriculum designed to prepare students for innovative careers in scientific research, technological development, and engineering. This interdisciplinary program combines foundational physics principles with advanced applied and experimental techniques, enabling students to understand and manipulate complex physical systems. Students will engage in coursework spanning classical and quantum mechanics, electromagnetism, thermodynamics, and statistical physics, integrated with specialized topics in applied physics such as materials science, optics, nanotechnology, and computational modeling.

Through laboratory work, research projects, and hands-on experimentation, students develop critical skills in experimental design, data analysis, and problem-solving. The program emphasizes the development of quantitative reasoning, technical proficiency, and innovative thinking. Students have access to state-of-the-art laboratories and research facilities, supporting projects that often involve collaborations with industry and research institutions. The curriculum is designed to foster a deep understanding of physical principles while cultivating the ability to translate scientific knowledge into practical applications.

The program also encourages interdisciplinary collaboration, allowing students to work with faculty and peers across engineering, applied mathematics, and computer science departments. Opportunities for internships, undergraduate research, and participation in cutting-edge projects prepare graduates for careers in academia, industry, or entrepreneurship. The applied physics program at Caltech aims to produce versatile scientists and engineers equipped with both theoretical knowledge and practical skills needed to advance technology and solve real-world problems. Upon graduation, students are well-positioned to pursue graduate studies or professional careers in fields such as aerospace, energy, materials science, and information technology.

• Common Application or the Coalition Application with Caltech Questions - Caltech does not have a preference between the Common Application or the Coalition Application. We advise that you use the best platform for your application process.
  • Note: Caltech is also a QuestBridge Partner. Students may apply for Caltech through the QuestBridge College Match Program.
• $75 application fee or fee waiver (Common App waiver, Coalition Application waiver, or Caltech-specific waiver)
• SAT with Optional Essay or ACT with Writing (official scores from testing agency)
• SAT Subject Test in Mathematics Level 2 (official scores from testing agency)
• 1 SAT science subject test: biology (ecological), biology (molecular), chemistry, or physics (official scores from testing agency)
• 1 math or science teacher evaluation
• 1 humanities or social sciences teacher evaluation
• Secondary School Report
• Academic transcripts
• TOEFL scores - Required of all international citizens unless 1) your native language is English; or 2) you have had school instruction for two or more years in English. The two years of school instruction must be completed prior to the application deadline). We do not accept the IELTS or any other substitute for the TOEFL requirement.
• International Financial Aid Statement of Intent - When an international citizen applies for freshman admission, the application prompts questions to confirm his/her understanding of our financial aid policy and thus confirm his/her financial aid intent towards Caltech. Caltech is need-sensitive for international citizens because the total amount of financial aid funds is limited for these students, and we remain committed to meeting the demonstrated need of all admitted students.
