Document Summary
It is the natural motion of every object to keep moving by itself. Newtonian physics does not apply to (1) high speed objects (2) small objects (3) strong forces. Biological evolution does not violate the law of entropy; the increase in entropy of the radiation (cid:862)f(cid:396)ee falli(cid:374)g(cid:863) gi(cid:448)es the i(cid:373)p(cid:396)essio(cid:374) of (cid:271)ei(cid:374)g weightless passing through living organisms is greater than the decrease in entropy of those organisms. 1st law of thermodynamics energy cannot be created or destroyed. 2nd law of thermodynamics entropy always increases.

Moving proton = electric and magnetic field. All magnetic forces are produced by charges in motion. Voltage is the amount of energy given to each coulomb of charge. High voltage across low resistance leads to a short circuit. Matter contains as many electrons as protons in total. Radio waves are electric currents oscillating in electronic devices.
