You don't consider Newton's "Law of Gravitation" to be a formal theory? How much more formal can you get than defining space and time and mass and force then relating them all with [image: F = G \frac{m_1 m_2}{r^2}\] ? I'm guessing you mean something different by a "formal theory" to what I would understand by that phrase. When I ask Edgar for a formal theory I'd be delighted to get something like Newton's law of gravitation rather than a load of hand waving verbiage. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
