🔣یکی از شگفتی‌های ریاضی این است که مجموع اعداد فرد متوالی همیشه به یک مربع کامل ختم می‌شود! این یعنی وقتی اعداد فرد را یکی یکی جمع می‌کنید، نتیجه همیشه یک مربع خواهد بود.
🟣به عنوان مثال: 1=1² 1+3=4=2² 1+3+5=9=3² 1+3+5+7=16=4² ... فرمول کلی این رابطه 1+3+...+(2n-1)=n²
❗️این الگو یک راز جذاب از دنیای ریاضی است که نشان میدهد چگونه یک جمع ساده می‌تواند به نتایج شگفت انگیز منتهی شود.

"He has to start being more proactive and to find a real solution to this situation, not stay in standby without interfering. It's a very irresponsible position from the owner of Telegram," she said. Telegram does offer end-to-end encrypted communications through Secret Chats, but this is not the default setting. Standard conversations use the MTProto method, enabling server-client encryption but with them stored on the server for ease-of-access. This makes using Telegram across multiple devices simple, but also means that the regular Telegram chats you’re having with folks are not as secure as you may believe. "Russians are really disconnected from the reality of what happening to their country," Andrey said. "So Telegram has become essential for understanding what's going on to the Russian-speaking world." He said that since his platform does not have the capacity to check all channels, it may restrict some in Russia and Ukraine "for the duration of the conflict," but then reversed course hours later after many users complained that Telegram was an important source of information. "There are several million Russians who can lift their head up from propaganda and try to look for other sources, and I'd say that most look for it on Telegram," he said.
