  • My friend Paul Newman (yes, that’s really his name, and no, not that Paul Newman) called me a year ago to ask if I’d like to help write a book about Apollo, which was the codename for Adobe AIR at that time. I was already overworked, but I hesitantly agreed. Although I’d known of Apollo in a general way prior to that, it was only at that point that I started to seriously take a look at the technology. Paul later had to bow out of the project due to other demands on his time, but I continued to look at Apollo and prepare to write...

  • Analysis and abatement of air pollution involve a variety of technical disciplines. Formation of the most prevalent pollutants occurs during the combustion process, a tightly coupled system involving fluid flow, mass and energy transport, and chemical kinetics. Its complexity is exemplified by the fact that, in many respects, the simplest hydrocarbon combustion, the methane-oxygen flame, has been quantitatively modeled only within the last several years.

  • In order to understand and manage our air quality resources, it is necessary to gain a fundamental understanding of the principles that govern our ability to do so. From a local perspective, it may be considered desirable to install huge fans in order to “blow the smog away,” but from a technological and scientific perspective it is not feasible. Likewise, from a regional or continental perspective, it is not acceptable to merely transfer air contaminants from one location to another one by dilution or “blowing it away.”...
