A request for concise physics books covering classical and modern topics has emerged, emphasizing the need for resources that are significantly shorter than traditional texts like "Physics for Scientists and Engineers" by Tipler and Mosca. Recommendations include the Feynman Lectures, noted for their clarity and comprehensible math, despite their length. Additionally, subscribing to Physics Today is suggested for updates on recent textbooks suitable for undergraduates. A specific mention is made of "Physics: A Student Companion" as a potential resource that aligns with the desire for brevity, aiming for a reference book under 500 pages to efficiently refresh knowledge in physics.
