Long description
To zdjęcie podoba mi się z kilku powodów:
- jest piękne,
- ma symboliczne znaczenie: małżeństwo, którego symbolem jest obrączka jest znakiem miłością (serce),
- jest naturalnym potwierdzeniem pewnych przekształceń matematycznych. Pierwotnie myślałem że to jest przekształcenie koła w kardioidę, ale ten cień ma 2 punkty osobliwe a kardioida tylko jeden)
Otwarta książka to słownik polsko-rosyjski. Czy te strony są wybrane losowo czy mają jakieś szczególne znaczenie? "jako że to była rocznica ślubu, wybrałem na haśle "miłość" ;-)" (Sebastian Tkacz)
I like this image very much because:
- it is beautiful,
- for me it's meaning is that marriage is a symbol of love,
- it is a natural example of some mappings: circle to non-cardioid heart curve
User Underwater has convinced me[1] that the shadow is not a cardioid but non-cardioid heart curve[2]. It has 2 singular points (cardioid has only one - cusp).

This opened book is a Polish-Russian dictionary.
It was a wedding anniversary so it is opend on the word "love".
