The discussion centers on identifying authoritative and comprehensive textbooks in STEM fields, referred to as "STEM Bibles." Participants suggest various texts across disciplines, emphasizing their depth, respect within the community, and comprehensive coverage of subjects. Key physics texts mentioned include "The Feynman Lectures on Physics," "Classical Mechanics" by Goldstein, and "Classical Electrodynamics" by Jackson. Quantum mechanics discussions highlight the lack of consensus on a definitive "bible," with suggestions like Griffiths and Ballentine being debated for their comprehensiveness and authority. Other fields such as medical physiology and electrical engineering are also discussed, with texts like Guyton's "Medical Physiology" and Sze's "Physics of Semiconductor Devices" being proposed. The conversation reflects a blend of personal preferences and community standards, with some participants questioning the criteria for a book to achieve "bible" status, particularly regarding size and depth. The dialogue showcases a rich exchange of opinions on essential literature across various scientific disciplines.
