    How many times is the word "inclusion" / "inclusive" abused?When I showed my tactile Rubik's cube around, someone said "it's an inclusive game. Sighted and blind can play".False. Rubik's cube like chess can be multi-sensory games, not inclusive. It's something different.You define "inclusive" when everyone, really everyone, can play. Including people with cognitive disabilities. But here, in front of those brain-involving games, it's not for everyone. For the games in question there are even fully sighted who don't manage to succeed playing, so, let's distinguish and tell the truth.I love both games, I play both of them, but I'm far from calling them "inclusive". The risk is to turn a very specific word, in an umbrella word. Like when someone uses "woke", or whatever else, eliminating the word's real meaning but wanting to create a false enemy with anything they don't approve. #RubiksCube #inclusion #words #language

    Solved my cube in about 15 minutes. It's a record as I just started learning a couple weeks ago. I know there are folks solving in second but it is not my time yet. #BlindCuber #RubiksCube

    @luca @nationsblind @BPI @mastoblind Unfortunately I must address you to a big tech place, but, search for "sensory cube". It has colors but also tactile textures.

    A Friday-afternoon puzzle about #RubiksCube:What's the shortest sequence of moves on the Cube which _non-obviously_ gets you back to where you started?By "non-obviously", I mean that it shouldn't be possible to _prove_ the sequence is a no-op by using only the obvious properties of the quarter-turn moves that they all have order 4, and opposite faces commute.To be group-theoretically formal about it, consider the following infinite group H, which captures those properties of the Cube moves but nothing more subtle:H = ⟨ L,R,F,B,U,D | LR=RL, FB=BF, UD=DU, L⁴=R⁴=U⁴=D⁴=F⁴=B⁴=e ⟩A sequence of moves is _obviously_ the identity if it's the identity even when you do it in H. What's the shortest sequence of moves that is the identity in the true Rubik's Cube group, but _not_ the identity in H?
