– – THAT EXPERIMENTALLY PROVE IT !

No it doesn't!
Only a complete fraud or an ignorant would claim it does!
Oh, look, I can draw something in 3d!
Therefore must be cubic!
Therefore it is PROVEN to be linked to everything else that is considered cubic for the same reason.
Oh, look, there are 13 cards in each suit in a deck of cards!
Therefore these are quite obviously linked to the 12 Olympian gods, and from there, obviously, to the 12 2nd-order personalities "types" that Cattell established.
(Let's ignore the difference between 12 and 13, though!)
Oh, look, a "baker's dozen" has 13 in it, but because it has the word "dozen" in it then it must link to 12!
Therefore 13 = 12!
So anything with 13 in it must equate to everything else which has 12!
Oh, look, there are two words in Biology (that I don't really understand the word of, but that's okay, 'cos surely noone else will either) that are to do with who we biologically are.
Therefore the gap between them must of course be God!
Oh, look, the brain has multiple parts!
Let's take only two of them ('cos, well, taking others wouldn't fit my conclusion) and multiply them twice to get 8.
8! Therefore it must be considered "Cubic"!
And therefore it is yet again EXPERIMENTALLY PROVEN to link directly to everything else that is "Cubic".
And therefore it is EXPERIMENTALLY PROVEN that my Rubik's Cube has 12 personalities (or is it 13? Or is it God?)!
Oh, and I must be right, as I've got an MS in Physics, was published once back in 1994, and also managed to have my photo taken with a well known person in the field of Psychology.
What more could I possibly tell you before you accept my PROOF!
Seriously, Mr Hammond, what you're posting is garbage, and you're treating this forum, and its members who have taken the time to honestly review what you have offered, with utter disrespect.
I have no doubt you've posted this nonsense in many places over the years, and have no doubt each and every one of them has sent you packing for being the crank you so obviously are.
I look forward to the day that this site does similarly.
