В этот день в 1964 году скончался советский ученый-биофизик Александр Чижевский. Это был человек «изобретательного ума», который он унаследовал от отца. А тот, генерал-майор, артиллерист, еще накануне Первой мировой войны выдвинул идею применения ракет в боевой обстановке. Среди других изобретений его особый командирский угломер для стрельбы с закрытых позиций, которым пользуются до сих пор. Чижевские жили в Калуге, и там отец познакомил Александра с Циолковским. Тот увлек его своими идеями – они больше 10 лет переписывались.

For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. At the start of 2018, the company attempted to launch an Initial Coin Offering (ICO) which would enable it to enable payments (and earn the cash that comes from doing so). The initial signals were promising, especially given Telegram’s user base is already fairly crypto-savvy. It raised an initial tranche of cash – worth more than a billion dollars – to help develop the coin before opening sales to the public. Unfortunately, third-party sales of coins bought in those initial fundraising rounds raised the ire of the SEC, which brought the hammer down on the whole operation. In 2020, officials ordered Telegram to pay a fine of $18.5 million and hand back much of the cash that it had raised. Now safely in France with his spouse and three of his children, Kliuchnikov scrolls through Telegram to learn about the devastation happening in his home country. 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. That hurt tech stocks. For the past few weeks, the 10-year yield has traded between 1.72% and 2%, as traders moved into the bond for safety when Russia headlines were ugly—and out of it when headlines improved. Now, the yield is touching its pandemic-era high. If the yield breaks above that level, that could signal that it’s on a sustainable path higher. Higher long-dated bond yields make future profits less valuable—and many tech companies are valued on the basis of profits forecast for many years in the future.
