Right from my high school i was very interested in maths and physics, and i want to be scientist in the field of quantum mechanics, particle physics. I took mechanical engineering at my college since it has wide application but here I'm not learning the m uch fundamentals of physics such as quantum mechanics, lagrangian and hamiltonainan mechanics only newtonian then we focus into solid, fluid dynamics.the engineering focus on concepts to build or explain something, but never focuses on concepts. My plan before was like after doing mechanical engineering, i can do nuclear engineer at post graduate level and start out my career as scientist in sub atomic level I like to build something like engineers do but i love to find out the reason being every physical law and always i wanted to answers the question why it it? How it is? So if I'm asked to build something for commercial purpose like engineers do I'm least bothered, because i wanna find something new about at very small scale like Einstein and other scientist found out theories. So should i quit engineering and study physics or else while studying engineering itself may i study subjects like classical, quantum mechanics and electrodynamics, quantum feild theory, etc..... I want to understand the fundamentals and apply engineering concepts to find out new thing about fundamentals.
