Pedagogical Notes

  1. When do children look at the stars? In our urban society, few people look up to contemplate the heavens, and there is so much light pollution that it is often difficult to see anything (the weather doesn't help either!). If we can't see the sky, we are denied some fundamental wonders to experience, and even in the countryside it is getting more difficult to see the events 'especially near the horizon ' where the events that were the basis of the calendar, navigation, and time reckoning occurred. The study of astronomy became an essential part of human activity, and led to significant developments in a wide variety of mathematical knowledge. The references below could encourage you to start something serious!
