> Some applications are too complex for math, so you just have to create really good simulations, like for example in wireless communications. Understanding the math behind those simulations is absolutely crucial to not getting bit by them. > One such example is smart watches. Some of the theory is less valuable there. The experience of working on low-power devices with engineers that do not understand the theoretical fundamentals of the devices they work with is an experience I can only describe as very, very painful. Smart watches are an excellent illustration of this, yes. "Smart" component selection with no understanding of the underlying complexity of the technology is a sure way to ensure you end up with crap that's 30% more expensive and 50% more power hungry than it should be.
