На уроке математики я столкнулась с задачей: «В старину часто пользовались солнечными часами, они известны более 3000 лет. В солнечных часах время определяется по положению тени от наклонного стержня на циферблате (циферблат и стержень располагали так, чтобы в полдень тень от стержня была направлена на отметку 12 ч). Подумайте, что общего у солнечных часов с современными, в чем их достоинства и недостатки». Я поняла, что практически ни чего не знаю о солнечных часах и заинтересовалась ими. В поиске информации я нашла много интересного материала о солнечных часах, который обобщила в данной работе.
In math class I was faced with a problem: "In the old days often used sundial, they are known more than 3,000 years. The sundial time is determined by the position of the shadow of the inclined shaft on the dial (dial and rod are arranged so that at noon the shadow of the rod was designed to mark 12 hours). Consider that the total hours of sunshine in a modern, what their strengths and weaknesses. " I realized that almost none of which I do not know about the sundial, and became interested in them. In search of information I found a lot of interesting material on the sundial, which is summarized in this paper.
