Finally, the final tab, “Man in the spotlight (1)” describes some optical experiments – an out-of-control hobby of this site’s webmaster – that are situated in a scientific, philosophical and religious context.

Part 1. An initial orientation text on light waves and an experiment based on destructive interference that may show us the first fine layer around our finger. (14 p.).

Part 2. A more scientifically oriented text for those who want to make sense of our experiments, possibly for those who want to redo them themselves. The Michelson and Morley experiment conducted in 1887 occupies an important place in this text. It then sought to show that in the universe there is no need to assume the existence of an evenly distributed fine substance called the “ether. However, in a somewhat modified form that we present here, and with an accuracy that may not have been possible at that time, this experiment does appear to demonstrate the very existence of an extremely fine substance, albeit in a non-uniform manner. And this seems to us to be a curious twist of fate: the same experiment then leads first to a falsification, and 125 years later and in a slightly modified form of it, to a verification. All this, and more, we want to explain in detail below.  (25 p.)

Part 3. Here the emphasis is not so much on the scientific content, but we go more into the philosophical and religious aspects of the existence or non-existence of “fine matter.” (22 p).
