The problem comes up because we ask the question in the wrong way. We supposed that solids were one thing and space quite another, or just nothing whatever. Then it appeared that space was no mere nothing, because solids couldn't do without it. But the mistake in the beginning was to think of solids and space as two different things, instead of as two aspects of the same thing. The point is that they are different but inseparable, like the front end and the rear end of a cat. Cut them apart, and the cat dies.
God made solids, but surfaces were the work of the devil.
Bodily fluids and solids are universally the most disgusting things we as human beings can come upon, but as long as they are inside us, it's part of you.
I shall consider human actions and desires in exactly the same manner, as though I were concerned with lines, planes and solids.
Everything you've learned in school as "obvious" becomes less and less obvious as you begin to study the universe. For example, there are no solids in the universe. There's not even a suggestion of a solid. There are no absolute continuums. There are no surfaces. There are no straight lines.
I should attempt to treat human vice and folly geometrically. . . the passions of hatred, anger, envy, and so on, considered in themselves, follow from the necessity and efficacy of nature. . . I shall, therefore, treat the nature and strength of the emotion in exactly the same manner, as though I were concerned with lines, planes, and solids.
Experimental evidence has now verified that nuclear reactions can be caused to occur in heavily loaded solids. It is premature to predict where this is headed from an applications point of view, but the basic science is clearly revolutionary.
Life is water, dancing to the tune of solids.
