Many ideas taught in elementary physics today are either false in fact or absurd in logic, and having been carried along by traditional practice, these errors and misconceptions continue to be promulgated. Many misconceptions and errors commonly found in current textbooks are examined. Areas dealt with are (1) forces, (2) gravitation, (3) energy, (4) molecular theory, (5) temperature, (6) thermodynamics, (7) heat transfer, (8) electro-magnetic radiation, (9) principles of current electricity, (10) c.g.s. units of electricity and magnetism, (11) atomic physics, (12) definitions, (13) general certificate of education physics, and (14) ancient and modern physics. A summary chapter, an appendix of notes and references, and a subject index are included.
