Chemical engineering.
Personally am majoring in Engineering as I have a strong passion for Chemical engineering. These field of engineering interest me because it involves finding scientific solutions to real-world problems in a more practical way than theoretical. Therefore, I chose my primary source as the WW1 X-RAY TUBE, which an Xray tube discovered by Wilhelm Conrad Rontgen, who was a German physicist between 1845 and 1923. The machine is reserved in the Museum of Technology in the UK as it came to very useful in World War One. Basically, the tube was used by surgeons to detect where bullets had explicitly penetrated in the head during the Great War. This device interests me as following its invention, up to date this device invented by Rontgen have been improved and in use globally for medical purposes. Viewing it from an engineering perspective, it was an invention that brought about a critical solution to a world problem.
Similarly, Chapter 24 of titled “An affluent society” details about the Growth of the west as well as various inventions that took place after World War II through the 1980s. These inventions changed American society, especially the coming of the TV generation. Such inventions can be related to the invention of the WW1 X-RAY TUBE, and up to date, any standard hospital globally must have an X-ray Unit.
