Hi! I'm 15 years old. I'm into IT, maths and physics. My hobby is amateur radio, DIY, electronics etc. I very like solve the most hard problems for example problems from Landau's book. I think that school textbooks aren't good source to learn physics. In my opinion good textbooks to learn physics are Feynman lectures, Physics Jay Orear, Physics Resnick Halliday and L. D. Landau & E. M. Lifshitz. I've a my blog at address http://hubot.pl/.
