Crackpot physics theory
Just wandering, the following can either be utter rubbish, or the most brilliant work(ehem!must be the genius or insanity in me).
We are all familiar with Coulomb's Law for static charges; inversely proportional to the square of the distance from a particular charge. However, the curious thing is that the electrostatic force becomes stronger and stronger, until it becomes infinitely strong at distance = 0. Thats wierd, doubly wierd. Firstly, if you place another charge, say 1 metre away from the orginal charge, and then u calculate the resultant force for a unit charge placed very very close to the the first charge, you still get a value close to infinity. After all, its not surprising if we recall the law of Superposition, that if you add infinity to any number, you get infinity. The above pic shows 3 negative charges placed along linearly on the x-axis; the y values represent the force you might measure for any x position.The second wierd thing, is that you can apparently violate Heisernberg's Uncertainty Principle. Lets assume we have a infinitesimal charge that itself has such a weak field that it is negligible. We can use this infinitesimal charge and go and measure the position of a charge particle. For easy analysis, we will just pretend the whole universe is empty and that there's only one lonely positive charge in space. Ok, we cant see this positive charge, but we can feel the force that the charge exerts on our infinitesimal charge. So we move along, measuring a few values, and then, we can measure the position of our positive charge quite accurately! The pic on the left illustrates how we can found that charge particle's position at (4,0) by taking measurements at (0,0), (4,3),(4,-3), and than looking at the intersection point.
Perhaps, the idea that the electrostatic force is inversely proportional to the square of the distance is not really true, we need to correct that, so that there is a finite value for distance equals zero. The clue as to how we may adjust may be lie in the belief that Heisernberg's Uncertainty is correct, therefore the charge must be in some sort motion if you try measure it, as it jiggles about, you cant possibly measure distance = 0, simply because its moving about its mean position.
Dinner now, perhaps more to come next time.
