Re: "Angel Girl"
Ok kids, shool's in session. I'm the new foreign teacher, so forgive me if sometime the terms i use are not exactly what your previous teacher used, feel free to point them out.
First and foremost there is no tecnology known to man to observe an electron, uncertainty principle(Werner Karl Heisenberg google it yourselves cause it's one long principle and a shortening just make it more confusing), for all tecnologies we posses that can detect sub-molecular structures are based on electro-magnetic waves(basically visible and non visible light if that makes it simpler), and such waves would alter the position of the particle(know as electron), there is no known way to determine where they "are" in a determinate moment.
The current image we have of atoms is based on theoretical analisys on the general "probability" of an electron being in a determinate position at a determinate point in time.
That being said you will never find atoms roaming around on their own, you can either find ions in solution in a fluid or you will find them in molecular forms, now that we know this important fact, we can see that matter works as a whole, we speak of individual atoms only from a theoretical point of view. The best example to make this a little clearer rests in the "Metallic bonds", in which we have a base skeleton of nuclei(protons/neutrons) and a sea of electrons that flow constantly, something similar to a region of sea with a great amount of whirlpools, this is the best example i can think of to explain why electrons don't fall in the nucleus, without resorting to quantum mechanics. The don't fall because there are many other nuclei that prevent it from happening, because matter(be it solid, liquid or aeriform) is all a big mass, the only difference being in the "speed" and distance of the ever moving atoms.
They should start teaching Quantum Physic in middle school, at least everyone would know what they're made off and that we're all part of the same broth...
Besides, there is no meaning in life beyond what you chose to give it for yourself.
