⚡️Boshqotirma plastik kubdan iborat. Kub ust tomonidan qardaganda 54 kichik kublardan tashkil topgan yirik kubni oʻzida mujassam etadi va 3 ta oʻqdan iborat boʻlib turli tomonlarga aylanadi. Har tomoni 9 ta kvadratlardan iborat va olti tusli ranglardan biriga bo'yalgan.
🎲 Ernyo Rubik 1970-yilllar oʻrtasida Budapeshtdagi Amaliy sanʼat akademiyasida Dizayn Interera boʻlimida ishlagan. Oʻsha davrlarda Ernyo oʻz talabalariga Matematik nazariyalarni hech tushuntira olmadi va guruh talabalari bilan bir kun 27 ta yog'ochli kublarni yasadi, har birini esa 6 xil ranglarga boʻyadi. Kutilmaganda ulardan yagona kubni yaratish mushkul ekanligi maʼlum boʻldi. Bu bilan Rubik butun oy davomida shugʻullandi. Ammo, eng qiyini esa uni mexanizmini yaratish boʻldi.

Despite Telegram's origins, its approach to users' security has privacy advocates worried. Unlike Silicon Valley giants such as Facebook and Twitter, which run very public anti-disinformation programs, Brooking said: "Telegram is famously lax or absent in its content moderation policy." If you initiate a Secret Chat, however, then these communications are end-to-end encrypted and are tied to the device you are using. That means it’s less convenient to access them across multiple platforms, but you are at far less risk of snooping. Back in the day, Secret Chats received some praise from the EFF, but the fact that its standard system isn’t as secure earned it some criticism. If you’re looking for something that is considered more reliable by privacy advocates, then Signal is the EFF’s preferred platform, although that too is not without some caveats. The Security Service of Ukraine said in a tweet that it was able to effectively target Russian convoys near Kyiv because of messages sent to an official Telegram bot account called "STOP Russian War." Since its launch in 2013, Telegram has grown from a simple messaging app to a broadcast network. Its user base isn’t as vast as WhatsApp’s, and its broadcast platform is a fraction the size of Twitter, but it’s nonetheless showing its use. While Telegram has been embroiled in controversy for much of its life, it has become a vital source of communication during the invasion of Ukraine. But, if all of this is new to you, let us explain, dear friends, what on Earth a Telegram is meant to be, and why you should, or should not, need to care.
