The seminar that I have chosen to guide me in the process of writing this unit will help me learn how machines work and how they affect the environment. Furthermore, I hope to learn how energy sources are used for machines and how this usage affects the environment.
Energy is a very abstract concept for me. I dare to say that I understand how energy works in the human body with lots of hesitation. But for me concepts such as heat or work, remain a mathematical and scientific enigma. On the one hand I am inclined to use technology and admire engineering ingenuity; on the other hand I have not dedicated time until now to understand how machines work. Moreover, I have not been able to clearly understand how energy sources are transformed for machines to work.
