Thoracic surgery is deeply intertwined with the principles of physics, which govern the tools and techniques used in various procedures. A thorough understanding of these principles is essential for the safe and effective use of surgical technology, advancing surgical techniques, and developing new medical devices. This manuscript provides a comprehensive overview of crucial physical principles relevant to thoracic surgery, such as radiosterilization, electrosurgery, fluid dynamics, endoscopic techniques, diffusion principles, and laser technologies. This manuscript aims to enhance thoracic surgeons' understanding of how physics underpins their practice by elucidating the connections between these principles and their medical applications. This multidisciplinary approach seeks to improve surgical outcomes by fostering a deeper appreciation of the fundamental science behind thoracic surgery, thereby encouraging innovation and the safe, effective use of advanced surgical technologies.
