>> Of all the qualifications I have ever taken, bar none, Engineering Design has been the most useful. I solved a major technical bugbear involving drilling ferrule holes in a brass DIL package in my first job simply by knowing (a) the correct drill bit and speed to use for brass, and (b) that the pillar drill could be adjusted to the correct speed. In my research career, I have built complex apparatus myself. At home, I don't bother returning flat-pack furniture for replacement or refund, I just sigh and fix the problem myself. While my tool-savvy friend carefully designs router templates, I wield a hand-held router by eye and refine the job with hand tools in half the time.
