**** Longevity week 18
Back at school the teacher once said all pulls reduce to pushes. The example used was the car ball pushes on the trailer coupling. The car is really pushing a towed trailer was the point. Not pulling it. He 'pulled' gravity, magnetism and electromagnetism out of this and it was all something a professor had once told him.
Personal definition of force is the exertion of matter upon matter. Which is, of course, potential and or actual acceleration. Reckon all post particle forces might be explainable by such. Sure the structure of the earth's inverse square law can be, don't believe there is such a thing as centripetal force and until a 'pull' has a clear definition, does anyone know that there is such thing as a pull. If a unified field theory was desired, clear mechanical definitions of what force is would be needed, perhaps negative charge positive gravity, atom probably splits because of annulment of charge on one side of a one proton. You would expect a charge to be an equal an opposite force system like a gravity field, anyway.
Hard to imagine a world solution short of teaching coming generations planetary motion through the motion of the sun.
Apologies for any inadequacies in translations out of Martian into Hebrew and Arabic. Peace in the trouble spots of your world is inspirable. Just needs earth professors to decide whether or not an earth school year is a speed differential with respect of the speed of a star. This world could settle down into longevity.
