I often refer to what happened on our planet long before my birth. And never cease to admire. I will not dig into deep antiquity, and will immediately touch upon the Renaissance. Leonardo, Mikelagelo, Raphael ... They worked 5 centuries ago and still remain unsurpassed. Leonardo was so ahead of his time that until the 20th century, many of his records remained incomprehensible. And the point is not that he wrote with a mirror hand and that he did not manage to organize his numerous manuscripts - simply the level of his ideas was inaccessible to many generations of descendants. He made a revolution in painting, made many discoveries in the field of anatomy, botany, cartography, mechanics. He described models of social management and made amazing theatrical performances. Today, the work of Leonardo does not cease to cause delight even against the background of the works of masters who worked centuries later. His manuscripts are collected by Bill Gates, and Artemy Lebedev continues to find in the diaries of genius thoughts that anticipated modern inventions. Previously, I was skeptical of historical documents - the idea that knowledge from the deep past can remain relevant in the modern world was incomprehensible to me. But today I read Leonardo with great pleasure and, of course, I advise everyone of that.
