Why is it that our furnances are not built as both a heating and air conditioning system which switches over automatically when the days are hot but the nights are cold? I know the thermostats have different temperature ranges for heating and cooling, but perhaps there could also be a “spring” and “fall” setting which blends the two?

Although I have many years of formal education, most of what I've learned has come from experimenting and trying to solve problems on my own. Once an idea for a project is set in my mind, it is all-consuming and one must learn everything possible about the subject on the way to the outcome. For learning is more than reading books and spoken word, it is hours of frustration, trial and error, and one sudden flash of insight when the world magically makes sense. It is during this moment when I am truely alive.
