    <content type="html">Моей тете было 19 лет, когда она родила первого сына. Он женился, когда ему тоже было 19 лет, и она стала бабушкой в 39. Если для упрощения предположить, что время поколения 20 лет, то две "короткие" тысячи лет, о которых пишут археологи, это 100 поколений. Я могу себе представить пять поколений своей семьи. Миллиардер Абрамович может купить документы о португальских предках 20-25 поколений назад. Получается, что цена более глубокого "копания" в семейной археологии, практически, недоступна сегодняшним жителям земли.&lt;br /&gt;&lt;br /&gt;С другой стороны, я бесплатно могу читать двухтысячелетние книги и знаки своего народа. Более того, во доминирующих человеческих культурах человек обязан читать и понимать такие книги. С точки зрения археолога, одна книга - одно поколение. Написана ли уже книга (текст), который будет у следующего поколения? Если да, то как бы ee прочитать?&lt;br /&gt;&lt;br /&gt;&lt;img src="https://www.dreamwidth.org/tools/commentcount?user=timelets&amp;ditemid=1370997" width="30" height="12" alt="comment count unavailable" style="vertical-align: middle;"/&gt; comments</content>

We also get two  triples of adjoint functors, depending on how we construct a fibered domain of the past (product vs coproduct). &lt;br /&gt;&lt;br /&gt;Lower-level past and future are modeled as exponential objects.&lt;br /&gt;&lt;br /&gt;Set&lt;sup&gt;past&lt;/sup&gt; -&amp;gt; Set&lt;sup&gt;future&lt;/sup&gt;&lt;br /&gt;&lt;br /&gt;&lt;img src="https://www.dreamwidth.org/tools/commentcount?user=timelets&amp;ditemid=1270187" width="30" height="12" alt="comment count unavailable" style="vertical-align: middle;"/&gt; comments</content>
