Отношение длин касательных к эллипсу равно отношению радиусов вписанных окружностей (синих) и корню кубическому из отношения радиусов соприкасающихся окружностей (красных), касающихся эллипса в тех же точках. Второе утверждение - теорема Лиувилля.

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.
