Hello, After reading https://www.physicsforums.com/showthread.php?t=128879", I started to be afraid that same situation applies to me. Let me describe situation. I'm currently a 15-year old sophomore in HS at US (though I only came to US 2.5 years ago). I have good skills at self-studying: I self-studied programming in C++ from Straustrup to Alexandresku and thank God, am in process of landing part-time C++ job. Six monthes ago, as well as five years ago (when I started programming), I was all set to go for computer science major and work as a soft.dev. Yet I assured myself this April that I don't want to develop for life but rather like doing science. Please, acknowledg e that I DO understand my choice might change and re-change times more but heck, it is interesting and what can I do?. Still, anyway, I, firstly interested in string theory through Green's video, got my hands quickly on first non-mathematical tutorial in quantum mechanics. Later in summer, on rather much mathematical textbook (Introduction to QM - Wileys). Right now I'm reading P&S - Intro. to QFT. Not to be a hypocrite, I was looking at school science fairs such as ISEF and would be pleased to go there. I'm afraid to say that and not be thrown tomatoes unto, but I'm trying to research. I confess that I'm trying to model molecular entanglement of sample and cantilever in magnetic resonance force microscopy; which is right now basically at the stage of solving Schroedinger equations for interacting systems and finding ways to prevent thermal decoherence from collapsing WF. After programming exp., linear algebra doesn't seem to be that hard to grasp in concepts. However, after reading thread mentioned early, my enthusiasm all vanished. I'm afraid my knowledge in other areas of physics is not as strong as it probably should be -- doesn't go further than first volume of Feynman. Should I just drop everything and start learning all physics and quit researching (if I am even allowed to use this word) to refraing from being restrained in one particular area? Still, I understand that I'll have to study every other area of physics in college in details and am open for that; well, I'm open for almost any sort of study, even history :) However, the idea that I'm just doing it wrong and too early is chasing me.
