Hi, I am a physics undergraduate student, and was wondering why so many people would prefer to become an Electrical Engineer or Mechanical Engineer as opposed to a Theoretical Physicist or a Mathematician or a Biologist? What attracts you to the applied science fields so much (APART FROM THE MONEY). Do you not find it exciting to ask fundamental questions like "Where did the universe come from?" or "How does it all work?" or "Why does it all exist?" or "What new knowledge mathematics can produce?" or "How and why life evolved?" ? I know, working as an electronics engineer for example, can be exciting too, making new kinds of circuits that could possibly change current technologies and take our societies forward. But isn't that more close to "helping societies progress", or in other words "social service"? One can get great pleasure from serving the society at large and making a difference in world at a practical level. And so, the excitement that you may get from being an engineer or an applied scientist, isn't it basically the excitement that you get from serving the society at large? Because, according to my personal view, as far as the excitement of new knowledge is considered, the pure and fundamental sciences do a better job of giving that. For example, as an electrical engineer, you may create a great deal of circuits having varied applications, some or most of which would be responsible for bettering our lives. But in the end, whatever you may create or do, rests on the four equations of maxwell, and a bit of math. So in the process, you have produced applications, different ways of doing a thing, bettered the human life, but have essentially produced no new fundamental knowledge. Working on applications is important, else the world wouldn't be the way it is today, but as far as excitement and fulfillment is considered, I guess pure sciences do a better job at that. These were my opinions. I'd like to hear from all you students of engineering/applied science and applied scientists out there.
