The rubix cube is a very popular toy. Though calling it a toy would be doing it a disservice. It has weaved it's way into pop culture in a way so rarely done. It is one of the only things you can learn in a few days that everyone else is convinced only masterminds can figure out. Though this is the case for the rubix cube. Not only that but it has had tons of spin offs and models. So many in fact that there are tons of official events for speedcubers around the world. Though before I ramble too much let's break down this phenomenon
While you may be disappointed to find out that the one person you know who can solve a rubix cube found out how to online but don't be! Almost no one figured it out for themselves. Anyone who has the mental capacity of a middle schooler can figure it out with enough time spent trying to understand the tutorials. I can speak from experience as I learned how to in middle school as well taught a friend who wanted to learn. That's the key. You just have to want to learn.
While it may seem all the same, there are a few different methods to choose from. At first you learn a beginner's method. After that you have a few choices. The most popular is CFOP. The difference between them is that CFOP takes a average of 50 moves while beginners method takes about 120. Though for beginners you need to learn seven algorithms. For full CFOP you need around 80 if you do F2l intuitively. If not it is well over 100.
Not only does the rubix cube exist, but there are many variants. For instance the 2x2. The traditional rubix cube is a 3x3. Mass produced you can go from 2x2 al the way to 13x13. That is the number of layers there are. Not to mention all the other ones. The mirror cube for instance shape shifts in a way that is hard to get your head around. Combine that with megaminxs and Square ones and it is madness.
Now you might be wondering the history of the rubix cube. Well the website ThoughtCo.com could not have said it better,
"Ernö Rubik is the one to praise or to blame, depending on how mad the Rubik's Cube has driven you. Born on July 13, 1944 in Budapest, Hungary, Rubik combined the divergent talents of his parents (his father was an engineer who designed gliders and his mother was an artist and a poetess) to become both a sculptor and an architect.
Fascinated with the concept of space, Rubik spent his free time — while working as a professor at the Academy of Applied Arts and Design in Budapest — designing puzzles that would open his students' minds to new ways of thinking about three-dimensional geometry.
In the spring of 1974, just shy of his 30th birthday, Rubik envisioned a small cube, with each side constructed of moveable squares. By the fall of 1974, his friends had helped him create the first wooden model of his idea.
At first, Rubik just enjoyed watching how the squares moved as he turned one section and then another. However, when he attempted to put the colors back again, he ran into difficulty. Oddly entranced by the challenge, Rubik spent a month turning the cube this way and that way until he finally realigned the colors.
When he handed other people the cube and they too had the same fascinated reaction, he realized he might have a toy puzzle on his hands that could really be worth some money"
This just about covers every aspect of the cube. It is a very mind boggling thing. Why don't you go watch some tutorials and see how long until you give up.
