MAN’S GADGETS OR THE MACHINES THAT DO THINGS

<jats:p>This book has its origin in the research I did for my PhD studies in architecture, at that time it was not easy for me to look for the publication of the work, I was more interested in finishing my studies and continue with my life. Time and chance led me to publish part of that thesis in my first book, however that publication did not cover all the work done so far, so that’s what’s decided by the editors, leaving out the part of the analysis of the machines and taking only the explanations of hydraulic engineering, mestizo processes and treaties and their analysis, the book published in 2010, two years after obtaining the PhD, represented my debut feature Hydraulic Engineering in Mexico sixteenth century and despite the happiness that caused me that first publication had the feeling that there was something that I still need to do. Besides, I never found a clear explanation as to why only half of the thesis had been published, perhaps the number of pages, or the choice of a topic evaluated as being of greater interest, that question had been going around in my head for some time. Why had hydraulic machines been left out?</jats:p>
