Древнеримский(!) водяной насос, Испания, датировка — I век н.э.

Найден в античной шахте рядом с городом Сотиэль-Коронада, Андалусия, юго-запад Испании. Сделан из бронзы. Использовался для разрушения струей воды нагретой огнем породы.

Хоть убейте, но выглядит эта штука как напорный насос времен начала промышленной революции, век эдак XVIII или даже XIX. Снимаю шляпу перед римскими инженерами и конструкторами!

На медиаболоке 5 — видео с иллюстрацией принципа его работы.

Национальный музей археологии (исп. Museo Nacional de Arqueología), Мадрид, Испания

On December 23rd, 2020, Pavel Durov posted to his channel that the company would need to start generating revenue. In early 2021, he added that any advertising on the platform would not use user data for targeting, and that it would be focused on “large one-to-many channels.” He pledged that ads would be “non-intrusive” and that most users would simply not notice any change. And indeed, volatility has been a hallmark of the market environment so far in 2022, with the S&P 500 still down more than 10% for the year-to-date after first sliding into a correction last month. The CBOE Volatility Index, or VIX, has held at a lofty level of more than 30. Under the Sebi Act, the regulator has the power to carry out search and seizure of books, registers, documents including electronics and digital devices from any person associated with the securities market. He floated the idea of restricting the use of Telegram in Ukraine and Russia, a suggestion that was met with fierce opposition from users. Shortly after, Durov backed off the idea. At this point, however, Durov had already been working on Telegram with his brother, and further planned a mobile-first social network with an explicit focus on anti-censorship. Later in April, he told TechCrunch that he had left Russia and had “no plans to go back,” saying that the nation was currently “incompatible with internet business at the moment.” He added later that he was looking for a country that matched his libertarian ideals to base his next startup.
