If Nature is not Supersymmetric, then it is not as elegant as it is made out to be. –(paraphrasing) PvN

Having found my Superpartner (glossary of this paper might help), wish my name started with ‘N’… Eh… I’ll have you know, on second thought, it sort of does: it’s the name that my father uses to call me. I also remember (one of) his elder brother(s) (he, my uncle, also has a son with the same name as mine!) once telling him to stop calling me that because I was (apparently) no longer a kid. So my father, for a while, started using my ‘official’ name, which sounded weird to both of us and so he’s back to using the N-word! Anyway, enough with such trivial personal stories, I do like my current name is the moral of the story.

So, what else can I rant about in this post? Let me remind myself of one of her Superpowers: She can solve Sudokus without needing a program. In other words, She is in very friendly terms with the numbers 1-9. You may ask: How is that a superpower? I may reply: (ignoring my first reaction – I can call it whatever I like!) I gave her a Sudoku from Beelzebub Chapter 135 to solve:

Original Sudoku

Between us, this Sudoku is invalid, i.e. it doesn’t have a solution as told me by my program Smile:

Invalid Sudoku

After having a go at it, she claimed to have solved it and I (obviously) did NOT believe her. She elaborated then that the Sudoku as I gave her couldn’t be solved but if one changes just the number ‘9’ in Squ.[1,3] to ‘2’, it can be solved and she showed me her solution:

Modified Sudoku

I checked her solution to the modified Sudoku in my program, which told me that this new Sudoku doesn’t have a unique solution due to 3 occurrences of a (1,9) doublet (which made me think it had 3 solutions):

Multiple Solutions

So I told her that her solution is one of many (just to annoy her a bit; She was already annoyed when I ‘doubted’ her ability to solve a Sudoku!) and She replied: “Yes, there are two solutions, flip 1 ⇔ 9…”.

My jaws dropped:

2 Solutions
