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.

Telegram | DID YOU KNOW?

The next bit isn’t clear, but Durov reportedly claimed that his resignation, dated March 21st, was an April Fools’ prank. TechCrunch implies that it was a matter of principle, but it’s hard to be clear on the wheres, whos and whys. Similarly, on April 17th, the Moscow Times quoted Durov as saying that he quit the company after being pressured to reveal account details about Ukrainians protesting the then-president Viktor Yanukovych. Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. Anastasia Vlasova/Getty Images 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. You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp.
