Here's something I think about a lot: of these three traits, which is the least desirable? I have gone in circles for several years now and run the proverbial gamut, befriending people with these three traits (often several, actually.) I always ask myself: is it better to be kind and dumb or be intelligent, yet callous?
If I subscribed to the "agent" philosophy of personal relationships, I would most likely never befriend people of the third type₁, since they seldom have skills to offer (at least at first glance), interestingly enough, one of my better and "more useful" friends is both type one and two. This particular friend is politically misguided (to a... (read 666 more words →)
Reversible/Carnot cycles in heat engines are a theoretical model that describe a system with perfect efficiency within each of the cycles. The Carnot heat engine is a model used in Thermodynamics 1 to introduce heat engines to students. The point of this is to allow students to focus on the four constituent cycles of the heat engine without worrying about tracking inefficiencies. It is, of course, impossible to design a heat engine that is operating at perfect efficiency with perfect reversibility.
Your are correct in your assumption that the Carnot cycle is just a distillation of the core principles of heat engines. Because of this, the Carnot model also helps at a higher... (read more)
