Thinking of the … WebIn classical mechanics we are usually interested in solving the equations of motion of a point particle under the action of some prescribed force. A method for doing this in a systematic way is given by Newton's equation F = m a, where F is the force applied, m is the mass, and a is the acceleration.
WebHe developed a unique approach to quantum mechanics, measurement algebra, and a general quantum action principle. His discoveries include 'Feynman's' parameters and 'Glauber's' coherent states; in later years he also developed an alternative to operator field theory which he called Source Theory, reflecting his profound phenomenological bent.
