Many students and schoolchildren often skip classes and lectures, and then find themselves on the brink of expulsion or of “failing” the exams they need. Having brought the situation to a critical point, at the last moment they ask themselves how to master the subject in a few months or weeks, where to get physics lectures and how to master the subject as painlessly as possible.
You must understand that any science is somewhat like a huge pie with several layers of filling. Mastering physics quickly simply will not work – it is equivalent to eating this pie in one sitting and mixing it all up in the stomach (the head). A standard course consists of about ten sections, which are, of course, connected with one another, and they must be mastered gradually, plunging deeper and deeper into knowledge of the world.
One should begin with mechanics, then move on to the basics of thermodynamics and the molecular kinetic theory. This is the main pillar of physics, without which further study is simply impossible. Having mastered these sections, move on to electricity, optics, quantum mechanics and nuclear theory. To study all this one needs a good grasp of mathematics and geometry, so you will certainly need a minimum of school knowledge.
Be sure to alternate the study of theory with practice, solve as many problems as possible, memorise formulas and grasp the heart of physics itself. You will need to keep a notebook in which all the terms are written down – you must clearly separate them from one another. Do not be lazy about doing laboratory work; understand that physics is a practical science that requires experiments and abstract thinking. In addition, write small crib sheets for yourself – this way you will remember formulas, quantities, units of measurement and other nuances of the subject better. Be sure to read more lectures and try to understand them. At a certain point you will realise that the main thing is not numbers and formulas but drawing up the right algorithm of calculation and the principles of solving problems! In a word, it really is possible to master the school physics course on your own in a short time, but for this you will have to want to and try hard!
