Curiosity demands that we ask questions, that we try to put things together and try to understand this multitude of aspects as perhaps resulting from the action of a relatively small number of elementary things and forces acting in an infinite variety of combinations.......A great deal is amalgamated, but there are always many wires or threads hanging out in all directions......The question is , of course, is it going to be possible to amalgamate everything, and merely discover that this world represents different aspects of one thing? Nobody knows. All we know is that as we go along, we find we can amalgamate pieces, and then we find some pieces that do not fit, and we keep trying to put the jigsaw puzzle together.回应 20150331 06:14

When we say we are a pile of atoms, we do not mean we are merely a pile of atoms, because a pile of atoms which is not repeated from one to the other might well have possibilities which you see before you in the mirror.20150331 06:10

You might ask why we cannot teach physics by just giving the basic laws on page one and then showing how they work in all possible circumstances, as we do in Euclidean geometry, where we state the axioms and then make all sorts of deductions.......We cannot do it in this way for two reasons. First, we do not yet to know all the basic laws: there is an expanding frontier of ignorance. Second, the c...20150316 16:54
You might ask why we cannot teach physics by just giving the basic laws on page one and then showing how they work in all possible circumstances, as we do in Euclidean geometry, where we state the axioms and then make all sorts of deductions.......We cannot do it in this way for two reasons. First, we do not yet to know all the basic laws: there is an expanding frontier of ignorance. Second, the correct statement of laws of physics involves some very unfamiliar ideas which require advanced mathematics for their description. Therefore, one needs a considerable amount of preparatory training even to learn what the words mean.......Each piece, or part, of the whole of nature is always merely an approximation to the complete truth, or the complete truth so far we know it. In fact, everything we know is only some kind of approximation, because we know that we do not know all the laws as yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected.The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific "truth". But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us the hints. But also needed is imagination to create from these hints the great generalizations  to guess at wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we've made the right guess.回应 20150316 16:54
