I am taking engineering 101 this semester so I know that the definition of engineering encompasses many different sections like chemical, structural and electrical, applying science to actual use. From this course specifically we have been discussing civil engineering, applying science and math to buildings and waterways and or systems. It has been really interesting to see the structures and systems from the past, and discussing how sophisticated some of them were, still people question how, without modern day tools, these structures were built and still standing. Civil engineering has obviously been the theme for the majority of our modules so far. Really the only module that did not involve engineering was the module on Thanksgiving. Discussing the significance of the size and design of the bridges especially for the era that they were built in. The same goes for the module on the Aztecs and the incredible structures they were capable of building with no present day architectural tools. Now moving to talking about the sophisticated irrigation systems that the Hohokam built, still encompassing civil engineering.
