The time and the calendar
Время и календарь …Люди научились точно учитывать время, когда развилась астрономия — наука о небесных светилах. Только благодаря астрономии мы умеем точно ответить на вопросы: «который час?», «какое сегодня число?», так как эта наука дала правила выверки часов и правила счета дней и годов, то есть то, что называется календарем. Объяснению этих правил и посвящена предлагаемая брошюра. |
