Hello, I am a retired engineer in the field of telecommunications per satellite (Alcatel Alenia Space). I am fascinated by quantum physics since a few years. I started by reading a lot of popularization books in this field but I tried to avoid the underlying maths. Recently I decided to lift the veil precautiously and I went into the "The Theoretical Minimum" by Leonard Susskind. I am also very interested by alternative énergies and everything that is scientific or simply technical.
