In engineering, chemical engineering (TR:7) (LH:201) (TL:208) is the study of chemistry pure and applied in matters of engineering, e.g. construction, design, synthesis or analysis; a chemical engineer is one who practices the art of chemical engineering, pure or applied.


The following are related quotes:

“On the meaning of vitalism. We have seen that it means that there must be something else in a biological system which cannot be included under the heading of ‘physics’ or ‘chemistry’. This must be some sort of ‘force[1] or some directing ‘spirit’ – this is the sort of idea that appeals to the non-scientists. Scientists, on the other hand, prefer to think that there will be ‘extra laws’ in biological systems, which are not included in physics and chemistry. The difficulty with this last point is to say clearly what sort of thing such an extra law would be, and, even more, to give a concrete example of one. In a certain sense it could be argued that natural selection is such an extra law, and I would certainly think it was a law of the most fundamental importance for biological systems. But it is not at all clear that something like it could not have been deduced from the study of, say, the chemistry of open systems. It is quite conceivable, that the study of chemical engineering would have thrown up a law similar to natural selection, since if we came across anything in the form of a replication process in a simple chemical system we would be confronted with behavior of this kind. Such behavior, however, may be exceedingly rare. But what test could be used to refute vitalism? One obvious approach could be to try and make some ‘biological’ object completely synthetically, starting from chemical elements. It would certainly disturb many people if some simple living organism could be made in this way. Nevertheless, I foresee that even if it were done there would be those who would claim that the system, having been made by us was then ‘colonized’ by the ‘vitalistic force’, or the ‘soul’, or whatever they might like to call it, which thus took over the workings of the system. So, in addition to being able to ‘synthesize’ it we see that it is necessary to explain the ‘behavior’ of the organism in terms of physical and chemical laws.”
