Is the purpose of theoretical physics to be no more than a cataloging of all the things that can happen when particles interact with each other and seperate? Or is it to be an understanding at a deeper level in which there are things that are not directly observable (as the underlying quantized fields are) but in terms of which we shall have a more fundamental understanding?

The realization that systems are integrated wholes that cannot be understood by analysis was even more shocking in physics than in biology. Ever since Newton, physicists had believed that all physical phenomena could be reduced to the properties of hard and solid material particles. In the 1920s, however, quantum theory forced them to accept the fact that the solid material objects of classical physics dissolve at the subatomic level into wavelike patterns of probabilities. These patterns, moreover, do not represent probabilities of things, but rather probabilities of interconnections. The subatomic particles have no meaning as isolated entities but can be understood only as interconnections, or correlations, among various processes of observation and measurement. In other words, subatomic particles are not “things” but interconnections among things, and these, in turn, are interconnections among other things, and so on. In quantum theory we never end up with any “things”; we always deal with interconnections.

The recognition of certain basic impossibilities has laid the foundations of some major principles of physics and chemistry; similarly, recognition of the impossibility of understanding living things in terms of physics and chemistry, far from setting limits to our understanding of life, will guide it in the right direction. And even if the demonstration of this impossibility should prove of no great advantage in the pursuit of discovery, such a demonstration would help to draw a truer image of life and man than that given us by the present basic concepts of biology.

We understand many things about particles and their interactions, but this and other mysteries make it very clear that we are nowhere close to a full understanding.

"I believe that there are things which humanity will never fully understand, for in the understanding of them, we will no longer be "human." One of these things is the Mr. Clean Magic Eraser. I don't know how it works, and I don't want to know. It's a big universe and even with our limited understanding of it, it's pretty clear that the universe is in no way equipped to keep up with the bureaucracy of its particles and/or strings. There are things lurking in the dark, unwatched, unguarded recesses of reality. Things as beyond you or I as we are beyond an amoeba. It is quite obvious that Mr. Clean Magic Erasers draw their power from these unknowable horrors. They probably found it in the core of a meteor still half buried in the Earth, hideously pulsing with a light not unlike the color of blood and hate. So use your Magic Erasers while you still can, before they run out of meteor or they discover it causes cervical cancer or testicular cancer in men and women respectively."
