Can a Mechanical Engineer help society?? I really much into in how science and technology, math and physics can help society in a practical way(i dont mean that theoretical dosent do any good so dont come with that). Some times i feel science is used just to make unnecesary needs for people. Personally if my country wouldnt be that violent i could walk to school with no problem, without using a car, but i know that ambulances are very necessary, and a lot of things like that. Well i wana work with renowable energy, and how we generate the electricity that we use every day. So can a degree in Mechanical Engineering help me with that?
