Recently I heard about this surprising theorem. I already knew about Fáry’s theorem: if a simple graph can be drawn on the plane without crossing edges (i.e. if the graph is planar), then it can always be drawn in such a way that all edges are non-crossing straight lines. Hence, restricting to straight-line edges doesn’t give a strictly smaller class of planar graphs. I found this to be quite surprising already.
However, much more is true: you can always draw a simple planar graph in the plane in such a way that you can place non-overlapping circles on the vertices, such that two circles touch if and only if the corresponding vertices are joined by an edge. In particular, the drawing clearly satisfies the result of Fáry’s theorem. This result is called the circle packing theorem.
“Noo, stupid, stupid Kuru-nee! You can drown in a cocktail shaker for all I care!”
During break the first year sisters Kururi and Mairu were fighting over an extremely meaningless topic.
“Both of them are similar though, right?”
The boy who stated that not reading the mood was glared at by the two of them with a look that said “this guy doesn’t even know anything…..”, and although receiving a shock he has doubt over his own disposition with his heart throbbing at the strangeness of those cold gazes, but that is an entirely another matter.
“But Yuuhei Hanejima would like both of them, right?”
When a girl nearby said that, the two of them nodded at the exact same timing.
Hearing that, their classmates laugh in amazement.
Yo, short ass sentence prompt. High school au cat the cheerleader and Kara the jock. Go! NC x
“Why do you pretend to be so mean to everyone?” Kara asked without looking up from her advanced mathematics book. Cat narrowed her eyes at the words, scratched out a circle in her cheerleading graph before adding something to it and the tip of her bright red pen almost ripping the paper. “Because, I’ve noticed being a rich blond girl in highschool isn’t exactly a sinecure and I am determined to thrive and to be remembered for it. This is why I chose to appear strong and unmovable, bitchy even. I don’t want people to see me as soft and caring.” This time, Kara looked up from her textbook and Cat felt her heart race into her chest at the sight of the bright, bright smile etched on the other girl’s lips. “I see you as soft and caring and I respect you, maybe more than all the jerks you’re hanging around with.” The kindness in Kara’s voice melted Cat’s reason and she finally smiled too. “I know. I still don’t understand how exactly you managed to get through my walls but … I’m glad you did.” She admited, her voice so low and small she doubted Kara heard her.
The smile on Kara’s face, bright as a thousand suns and the love, pure as crystal water, swimming in the ocean blue eyes let her know she’s been heard, loud and clear.
