Rethinking Newton’s Principia

It is widely accepted that the notion of inertial frame is central to Newtonian mechanics, and that the correct space-time structure underlying Newton’s methods in Principia is neo-Newtonian or Galilean space-time. I argue to the contrary that inertial frames are not needed in Newton’s theory of motion, and that the right space-time structure for Newton’s Principia requires the notion of parall...

Some Reflections on Newton’s ‘Principia’

We examine the text of Principia to discover the extent to which Newton’s claims about his own contribution to it were justified. We argue that the general Scholium, written twenty six years after the first edition, substantially misrepresents the main body of the text for polemical reasons. We discuss papers of Wallis, Wren and Huygens that use the third law of motion, as stated by Newton in B...

Synopsis of the Principia Cybernetica Project

1 Principia Cybernetica Ends: Metasystem Transition Theory As the name Principia Cybernetica implies, it is a project intended to clarify the fundamental principles and produce a uniication of the foundations of the domains of cybernetics and systems science. The philosophical system created by Principia Cybernetica is seen as a clearly thought out and well-formulated, global \world view", inte...
