High school students interested in physics can benefit from a variety of resources, including online courses, textbooks, and lecture series. Recommended materials include the Feynman Lectures, which are available for free online, and Paul Hewitt's "Conceptual Physics," which is accessible without heavy math. Websites like MIT's OpenCourseWare provide free physics classes, while Wikipedia articles on topics like dark matter and unsolved physics problems offer foundational knowledge. Engaging with MOOCs on platforms like edX and Coursera can enhance learning through structured content and peer interaction. These resources collectively support a deeper understanding of physics concepts and encourage further exploration in the field.
