how to see invisible things

in the past, very long time ago there was a little group of mans that used to believe in "a thing" that is more little than the littlest thing that the human can see, and that very, very little thing are the "brick that builds the edification that is the world". Today we know that Democrito and leucipo wast´n wrong, also we can say that we know how this "littles bricks" are, how they work, what they do, where they are, even how they called, but we did´t see any one of them. so? how can i see a invisible thing? like the blind people see, using everything except his eyes.

I thing, that the most important material in the universe are the atoms, why? Its obvious they are everything, they are your food, yours clothes, your friends, your mom,  even yourself and using that same idea i thing that we should learn so much of the atoms as we can, the human should know everything about them and having that knowledge we can do anything.

We always have use them, even when we don´t know they even exist, we use them in every moment of our lives,when you cook, even when you love, there is atoms in your atoms formed body, loving another group of atoms. we always use them, because we always have been them, sounds like a weird kind of pray, but its not a religion, its sciences.
