Varying coordinates were the first to suggest relativities. Although, these were far from Einstein’s relativities, they pointed at the direction that the world and the systems in it are scaled differently. They extended the cognitive process of generalisations enabling the observer to expand his former, narrower views about the world.
This is how, essentially in the 19th century, our concepts of space were liberated from the orthogonally fixed three-dimensional world. With the Bolyai-Lobachevsky revolution, spaces curved in the fourth dimension led to Einstein’s space-world and possibly even further. A basic scheme of our systems approach is the evolutionary continuity of this generalising freedom of thought.
The relativity of our sense of time is an old topic in literature but it is also related to the philosophical and scientific-practical problem of cause and effect.
