History is important: it explains us how we got to the place were we are and interferes more with our future than many would admit. This is true in life, but also in science. In lecturing we usually teach concepts and methodologies, many developed in the last five centuries and they are all developed with a background. This background tells us a lot about why these methodologies gained its importance they nowadays have and only when we understand them we understand why they are so highlighted compared to other methodologies, which we do not necessarily teach nowadays. Nevertheless, usually we keep the mentioning of this background quite brief and when at all, some words about it can be found in books. But is it the right way?
