The following are the disciplines in Engineering and the richest men in the world are engineers. Engineering is the most lucrative discipline in the world and it has transformed the world with imagination.
In the chemical industries, engineers maintain all the machines used for the manufacturing of Chemicals like H2SO4, HCl, drugs and produce all the medical equipment/machines etc. Engineers at GE developed a magnetic field that is 30 times bigger than the earth's magnetic field and built the emerald machine( MRI machine) use to scan or view the human brains. This has transformed the medical world immensely.
