I have a phone, and I have no idea how it actually works despite the fact that people, like me, created it. I know that there are detailed descriptions of its operation, nevertheless, when I make a call, it is magic for me. I am used to it, and I perceive it as something routine, but it is still a kind of magic.
We are surrounded by these “black boxes” that perform some operations we do not understand. We have created some of them and, generally, understand what they do. Some “boxes”, however, were created by nature and we have poor understanding of their magic, or we have none at all.
