Excerpt from Harper's Electricity Book for Boys

But this does not mean that we have now accomplished all that there is to be done. On the contrary, the next half century will be full of wonderful advances. This makes it more than ever essential that we should become acquainted with the principles and present conditions of a science which is being applied more and more closely to the work of every day life. It is necessary to know this from the inside, not simply from general descriptions. Theory is all very well, but there is nothing like mastering principles, and then applying them and working out results for one's self.
