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

Telegram | DID YOU KNOW?

Date: |

On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. "Like the bombing of the maternity ward in Mariupol," he said, "Even before it hits the news, you see the videos on the Telegram channels." To that end, when files are actively downloading, a new icon now appears in the Search bar that users can tap to view and manage downloads, pause and resume all downloads or just individual items, and select one to increase its priority or view it in a chat. Right now the digital security needs of Russians and Ukrainians are very different, and they lead to very different caveats about how to mitigate the risks associated with using Telegram. For Ukrainians in Ukraine, whose physical safety is at risk because they are in a war zone, digital security is probably not their highest priority. They may value access to news and communication with their loved ones over making sure that all of their communications are encrypted in such a manner that they are indecipherable to Telegram, its employees, or governments with court orders. Friday’s performance was part of a larger shift. For the week, the Dow, S&P 500 and Nasdaq fell 2%, 2.9%, and 3.5%, respectively.
