Totally agree with that ^ No point knowing the theory if you dont have the capability to put it into practice. The dude who wrote that email says hes a student engineer, so technically he isn't even a engineer, well not yet anyway lol. Do surgeons get pissed off when gardeners call themselves ' tree surgeons ' haha ? So lets say an engineer is a designer or inventor, what about the guys physically building the bridge, for example, what are they then ? See i'd class them as the engineers.
