Countryside: good food, good coffee, silence (alright maybe just my brother watching Le Tour de France!, but I like that after-lunch, slow TV chat), gardens and nature... and time to read some old books with astro algorithms in C++ <3

I really like the figure in the ecliptic–equatorial coordinates section. How equinoxes are the points in which us (Earth) change from travelling above->below (spring) or below->above (autumn) the equatorial plane. And how the 23.5° angle causing seasons is seen!
