Hello everybody at the forum. My name is Alejandro, and I am a spanish telecommunication engineer, currently working as technologies teacher. My passion has always been physics, and I even thought seriously of studying a physics degree instead of my telecommunication degree. But now, at my 35, I have decided to study physics, just for intellectual pleasure and as a hobby (well, actually I began my physics studies one year ago). Because of my telecomm degree, I have knowledge of general physics, calculus, algebra, electromagnetic fields, etc, so I do not start from zero. I also studied differential equiations (boths ordinary and diferential), but I have forgotten almost it all about ODEs and PDEs. Now, I have "designed" the following curriculum for my studies, and besides, I have chosen the textbooks I will follow for the different subjects: 1) Classical Mechanics. The book I have chosen is Taylor's "Classical Mechanics". Good book in my opinion 2) Classical electrodynamics. For this subject, my choice is Griffiths' "Introduction to electrodynamics" (actually, I have "fallen in love" with this book. I find it is a jewel). For the time being, I have almost finished with these two subjects, so I am planing my next steps. I think they will be the following: 3) Special relativity. For this subject, I have serious doubts about which book will be fine for me after reading Taylor and Griffiths. I have heard good things about Rindler's "Introduction to special relativity", and about the first chapters of Schutz "A firts book in General relativity". Lots of people suggest Taylor and Wheeler "Spacetime physics", but I do not like the vibe of this book. What do you think? Which would be the appropiate book for me? 4) Quantum mechanics. I have never studied QM, so Griffiths book on QM seems a good option for a introductory course (as I said, Iam really enjoyng his EM book). However, many people warn agaist this book. Other good choices should be Zettili's or Shankar's books, but I am not sure. Your opinion will be really wellcomed to take a decision. 5) Elementary particles. After QM, I would like to take a introductory look to Standard Model, and I think Griffiths' "Introduction to elementary particles" is, definetivelly, the right book for me. Do you agree? 6) General relativity. Once I have finished with Elementary Particles, I would like to get an introduction to GR. In this case, I am also convinced thar Carroll's "Spacetime and Geometry" is a very good book for that. What do you think? When I have finished with it all, I would think what subject called my attention the most, and I would take more advanced courses in that topic. But I have a long (but exciting!) journey until I get there, so it does not worry me too much. I have the possibility to study abot 2 or 3 hours a day, and I really enjoy with it, so it will not be a problem. I am not a geniuos, but a consider myself a smart person. All yor suggestions ang help will be helpful for me. Thanks all of you. Best regards. Alejandro. PS: See you in the threads in this forum.
