From Universe in Problems
This is an introductory chapter, intended to remind the readers of the quantities and concepts to be used later in the actual problems. The scope is too large, so you will not learn a subject if you don't know it yet, but this may help you have some fun while recalling what you already know and provides a heads-up for some of the more interesting, sometimes controversial, questions.
