An oft-repeated maxim is that learning by doing is the best type of learning. As easy as it is to believe, it seems that humanity, at least the part living in the developed world, is quickly moving in the direction of complete dependance on complicated gadgets designed by high tech companies that recruit brilliant scientists. Even if one wanted to build something, how can it be possible to compete with the world of highly advanced industry? As it turns out, the point is not to compete but to learn how to hack — hacking, not in the sense of breaking into computer systems, but in the sense of making things. That is the idea behind, Instructables, a site devoted to collecting community-generated do-it-yourself projects. Whether you want to make complex origami sculptures or your own boat, there are numerous visual guides and detailed instructions to help you out. Each project, is effectively a hands-on lesson and can be a starting point for further exploration of physics, math, and engineering principles.
