Reading chapter 3 of the shallows “Tools of The Mind”  was very interesting to learn about the chronological order of the development of different tools that today we consider to be an essential part of our daily life. Tools that were developed to expand our power and control over different situations, over time and distance. All created, with a common purpose; to facilitate a task at hand and be more efficient. Reading this chapter made me realized of the importance of the many tools that make our life easier and we take them for granted.
