In my relatively short engineering career I have had the chance to work on a variety of challenges and learn a fair amount about a number of topics. This is my effort to share my view and what I have learned along the way.
Why Rational Engineering? I think that application of reason and logic usually leads to a solution to most problems. Overall my approach is fairly simple: learn and improve. If you don't know something, ask questions and learn it. If something isn't optimal, determine what can improve it and try it.
The topics here will be wide ranging and some may not seem like engineering on the surface. However, my view is that when you take anything and improve it, you've done some type of problem solving (and all engineering is problem solving).
