🔣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.

Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. Given the pro-privacy stance of the platform, it’s taken as a given that it’ll be used for a number of reasons, not all of them good. And Telegram has been attached to a fair few scandals related to terrorism, sexual exploitation and crime. Back in 2015, Vox described Telegram as “ISIS’ app of choice,” saying that the platform’s real use is the ability to use channels to distribute material to large groups at once. Telegram has acted to remove public channels affiliated with terrorism, but Pavel Durov reiterated that he had no business snooping on private conversations. "Your messages about the movement of the enemy through the official chatbot … bring new trophies every day," the government agency tweeted. In addition, Telegram's architecture limits the ability to slow the spread of false information: the lack of a central public feed, and the fact that comments are easily disabled in channels, reduce the space for public pushback. "He has kind of an old-school cyber-libertarian world view where technology is there to set you free," Maréchal said.
