Hello everybody. Can't surrender so much easy... Take a look to this: www.geocities.com/k_pullo/suppose.htm You know the proccess: tell where do you see the faults, and then i will understand somethings, but new doubts will come to my mind. Thanks for all your support in physics, you're making a good job into my understanding, first on centrifugal-centripetal, then on magnets and finally into electrostatics. Will it be the end?... SURE NOT!
