Talk:2614: 2
Hello people. Anyone got an explanation for this? 172.70.114.229 22:59, 2 May 2022 (UTC)
To the person who has requested a citation that two is a number... here you go: https://youtu.be/dBVoIUASFS0?t=82. Can someone who knows how to add citations add it? :D --172.70.110.209 23:09, 2 May 2022 (UTC)
- The [citation needed] thing is a running joke here thanks to 285: Wikipedian Protester. It's used for obvious statements of fact on this wiki as a joke (basically the opposite of its Wikipedia use). KirbyDude25 (talk) 00:43, 3 May 2022 (UTC)
Hey all, the group theory thing reminds me a lot of cyclic groups or ideals generated by the value 2. Also equivalence classes (which come up in group theory) can be written with [brackets] but may be confused with <cyclic groups> or (ideals).
The 2;2 notation looks like the notation \mu; \nu that is used for covariant derivatives of tensors in physics. Also 2,2 looks like \mu, \nu that is used for partial derivatives of tensors. And as mentioned above, (2) could be a cyclic subgroup or ideal generated by two or a special case of cycle notation for elements of symmetry groups used to mean an element that keeps 2 fixed. 162.158.62.120 23:32, 2 May 2022 (UTC)
I second the point about tensors. Maybe you could expand the summation notation slightly. It's common to use index sets or rules underneath large symbols for all sorts of things, like sums, products, direct sums, direct products, unions, intersections, integrals, and much, much more. So here, the large 2 in parentheses represents one of these symbols. Rather than adding or multiplying the elements or whatever, you are twoing them, whatever that means. You are twoing over all values of 2, apparently. It's sort of reminiscent of jokes with punchlines like "for sufficiently large values of 2." There are of course, different 2s out there. Like, there is the von Neumann ordinal 2, the integer 2, the rational number 2, the real number 2, the complex number 2, the residue class of 2 mod 3, etc. All of these may be represented by 2. Perhaps we are indexing over some collection of canonical representations of 2? 172.70.130.161 00:02, 3 May 2022 (UTC)
Explanation needs something about one of the 2s being cursed. Also, this should be added to the category for cursed stuff (I think it's cursed things, but did not look it up).
