The Broken Spears Book Review essays

The Broken Spears Book Review essays Subject: The Broken Spears Book Review The Broken Spears, by Miguel Leon-Portilla, is a detailed and graphic account of the Spanish conquest, told from the point of view of the conquered (the Aztecs). Leon-Portillas selections of events portrayed in this book combine giving the reader a big picture view of the Spanish conquest. This book gives a historical event an emotional, human, perspective, which helps the reader understand and empathize with the terror and fear the Aztecs were faced with. The book also provides in-depth details concerning the correlation of superstitions, poor (or misguided) leadership, and technological disadvantages that led to the Aztecs being conquered. After reading this book one begins to understand how and why the Aztecs were conquered. I was always under the impression that Cortes was just a great leader with great army and his victory in Mexico was as easy as the US victory was in Iraq (it amazing how similar the two events are; both fed by the hunger for power, and greed). After reading this book I have begun to realize that Cortes may have been a good leader but there were many more circumstances stacked against the Aztecs. These circumstances include native allies of the Spaniards, non-indigenous disease, inferior weapons, and bad interpretations of the Spaniards intentions. The Aztecs did not seem to have any cards in their favor. Most importantly this book shows the stark contrast and ultimate clash of different cultures. The Aztecs superstitious and ceremonial way of life clashed with the brutal and savage methods of Cortes. While the Aztecs decorated idols and built statues the Spaniards planned surprise attacks, for ex ample the attack at the fiesta and the statue of Huitzilopochtli. This passage is found on page 72 and includes a graphic account of the Spaniards brutality. Throughout the entire book these cultural differences are present, forming and ...

The Evolution of GIS - Essay Example terature on this subject, it is clear that these two are the core components of the system and the manner by which they rapidly evolve has driven the pace by which GIS has changed and will change over time. This is supported by the evidences that follows. Essentially, GIS is defined as â€Å"the system of computer hardware, software, personnel, organizations, and business processes designed to support the capture, management, manipulation, analysis, modeling and display of spatially referenced data† (TRB, p.10). As with any type of computing technology, the GIS's own system is consisted of three basic parts, namely, the UI or the user interface, the tools, which is differentiated according to functions, and, finally, the data manager. Put in another way, the components of the system can be said to include data, technology, application and humans (Lloyd and Bunch, 2003, p.828). All of which have their respective and equally important functions. While the GIS could run in a sing le computer terminal, the optimum framework requires several computers for GIS operations - desktop, client server, centralized desktop and centralized server (Longley et al. 2005, p.158). These variables and operational framework underscore why hardware and software are critical in the progression of the GIS development. Hardware The invention of the silicon chip back in the 1970s launched the fast paced computer development (Pasewark and Pinard, 2007, p. 263). It led to the viability of personal computers, which became the precursor of the current technology typified by smaller, faster, powerful and cheap hardware. To put this environment in context, there is the so-called Moore’s Law which states that computer processing chips double in power almost every 18 months, making computer more... Thi essay stresses that the evolution of the GIS system can be attributed to several important technological developments. First, there are the advances in computing hardware, which made computers affordable and powerful. Today, many people and organizations can buy desktop systems not just in workplaces but even for home use. These are computers that can perform complicated tasks and functions with apparent ease. This report makes a conclusion that in order to depict the significance of the evolution of GIS in the past twenty years, it is important to go back to the importance of geographic information. Accurate and reliable geographic data do not only mean effective geographic expeditions or land mapping initiatives. Rather, they are imperative in many other endeavors such as in running a city or in predicting a catastrophe. This is the reason why GIS is an important technological tool and how its evolution should be of interest for people. In the past twenty years, there were significant achievements and the evolutionary path points to a more sophisticated and intuitive system that would help people to make sense not just of the Earth but also beyond. It is worth noting that today there are just numerous geographies or approaches to geography. One of GIS’ greatest contributions, as evidenced by its evolution, is the universalization and consistency of geographic information.
