At school we had the subject geometry. There we learned the special properties of special geometric shapes and how to construct them. For example, equilateral triangles or the centres of gravity of any triangle, or that the radius of a full circle can be drawn exactly seven times on it, or what special feature a Thales circle has, or how to construct median perpendiculars, and so on. These properties still fascinate me today. On the one hand, I find it extremely remarkable that there were and still are people who find out and empirically prove such laws, which were unknown until their discovery. On the other hand - and even more so - that such mysteries are simply present in our life and cosmos. It is like Easter with the hidden eggs: someone took the trouble to hide them - so that they would be discovered and people would be happy about them. Great work!
I wish you an extraordinary day!
