关于此电子书
The idea of engineering has been present since prehistoric times when humans started shaping important creations like lever, wheel and pulley. Every invention is reliable with the contemporary explanation of engineering manipulating basic principles of mechanics to develop useful tools and objects.
The word engineering has been derived from the term engineer and dates back to around recently 1325 and the word engineer in those times meant or denoted to someone who was the constructor of engines. The term engine has actually become obsolete now as it is now referred to a military machine or in a more detailed description it was a mechanical apparatus used in wars for eg: a catapult. Engine comes from an old word used in Latin ingenium which means intrinsic quality, particularly cerebral power, hereafter an ingenious creation.
