Подробный рассказ о Французской Геодезической Миссии в Перу. Как ученые доказали, что Земля - сплюснутый эллипсоид, а не просто шар. Эпоха Просвещения, экватор. Восемь лет измерений, безденежья и опасностей: лихорадка, индейцы, убийства. Короче говоря, обычная работа астрономов.
📌Выпуск: «На севере диком»
Полярный день и полярная ночь 1736 года: французские ученые ходят по непролазным лесам, спят в палатках, пишут письма, наблюдают звезды, северное сияние и стрелку компаса. А еще дивятся бревенчатым избам и комарам.

But Telegram says people want to keep their chat history when they get a new phone, and they like having a data backup that will sync their chats across multiple devices. And that is why they let people choose whether they want their messages to be encrypted or not. When not turned on, though, chats are stored on Telegram's services, which are scattered throughout the world. But it has "disclosed 0 bytes of user data to third parties, including governments," Telegram states on its website. The gold standard of encryption, known as end-to-end encryption, where only the sender and person who receives the message are able to see it, is available on Telegram only when the Secret Chat function is enabled. Voice and video calls are also completely encrypted. 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. "And that set off kind of a battle royale for control of the platform that Durov eventually lost," said Nathalie Maréchal of the Washington advocacy group Ranking Digital Rights. "There is a significant risk of insider threat or hacking of Telegram systems that could expose all of these chats to the Russian government," said Eva Galperin with the Electronic Frontier Foundation, which has called for Telegram to improve its privacy practices.
