the great social problems of our time’’ has been the subAttacking ject of a growing volume of comment, argument, and confusion. Some of the confusion, perhaps, has arisen from the fact that the nature of engineering practice has been changing at the same time that the nature of problems attacked by engineers has been changing. Both of these changes are momentous, and their simultaneous occurrence has made them difficult to grasp. Sifting through the maze of facts and impressions, John G. Truxal, Dean of Engineering a t Polytechnic Institute of Brooklyn, recently presented (ISA Journal, February 1966, page 6) a system to classify engineering problems that promises to clarify the situation by providing a framework in which to visualize what is happening. Dean Truxal breaks engineering into four categories : industrial, military and space, bioengineering, and societal (transportation, air and water pollution control and abatement, and system organization, for example). He points out that major funding has been provided historically for industrial needs, during and after World War I1 for military and space needs, and only recently to any extent for biomedical and societal engineering. Chemical engineering, in particular, still rests primarily on an industrial foundation. But the pressure for extension is mounting. More and more chemical engineers are penetrating into the other areas. I n doing so they, like other engineers, have found their working body of knowledge to be inadequate and have added an active chemical engineering research program in response. This research activity receives most of its financial support from granting agencies that are not industrially oriented. I n the past 15 years, it has flourished and grown. Until recently, in fact, many chemical engineers feared that it was growing so large that it was assuming a relative importance that threatened the traditional purpose of the profession. That fear has now subsided, for the most part, as the profession has learned to live with its new structure. But the whip of research has left many a mark on the original body of working knowledge. I t has, in fact, significantly changed the way much industrial chemical engineering is done, by adding more fundamental chemical understanding, more insight into the physical phenomena, and more mathematical competence to the engineer’s approach to his task. Meanwhile, chemical engineers, with this greater competence, are becoming more closely involved with the nonindustrial problem areas. Here the “chemical” part of the engineering task may well not predominate; in some cases it obviously does not. A new problem to be faced, therefore, is whether chemical engineering can deal effectively with these multidisciplinary, nonindustrial problems and retain its identity while doing so.
