Hearts, Again
Steven Kent Vogel · 1992
Abstract Hearts have repeatedly appeared in this account, and the reader may be wondering why the writer doesn’t get them off his chest once and for all. This circulatory machinery, though, is a well-integrated and coherent system, so we commonly need information about one part to take a more penetrating view of another. In addition (and more specifically) we’re now armed with the notions of diffusion, continuity, La place’s and Hooke’s laws, the Reynolds and Hagen-Poiseuille relation ships, and so forth, which we weren’t just a few chapters back. In a proper textbook the nonbiological underpinnings would be done at the start; but a textbook typically talks to a relatively involuntary reader who must put up with such deferral of gratification. (Perhaps the main difference between a nontext and a text, though, is that the nontext is designed to appeal to people looking for a decent level of novelty while the text is selected by people who often prefer a minimum of novelty.)
