Continuing in the quest to make sense of things around me, I stumbled into something quite thought-provoking. It has something to do with our idea of separating knowledge into the sciences and the arts.
It is interesting to note that the Ionians, of the Eastern part of the Greek civilisation, and the Hindu culture started learning things about the world we live in entirely independent of each other. It is incredible how quite similar their discoveries were, at least in the initial stages.
The pre-Socratic thinkers thought that there was a connection between the Universe and the world immediately around us. Thales tried to say that water is the essence of our existence. Democritus put forward the theory of Void and eternal, indivisible atoms that made up our physical world. Pythagoras and his cult members attempted very hard to a mathematical formula for everything in the Cosmos, including music. His equations, he later realised, could be irrational at times. A case in point is the irrationality of √2. The hypotenuse of a right-angled triangle with dimensions of 1 X 1 cannot be calculated probably made him abandon his idea. From that time onward, another branch of knowledge is said to have developed - natural philosophy. Later philosophers quit looking at the stars for the answers but instead started gazing inwardly. They abandoned the physical sciences to rhetorics. Their idea of problem-solving was people watching. This type of wisdom continued all through Plato and subsequent sages. As we know Plato's teachings metamorphosed into Neoplatonic ideas which greatly influenced the Abrahamic religions.
Attempts to revive sciences through the works of Kepler, Copernicus and Newton met a lot of resistance from the society so ingrained in a kind of a dogmatic belief. Some of the branches of the Abrahamism realised their loss of grip on the flock and decided to move with the times while some found content in spewing their 6th-century or maybe 12th-century slightly improved ideologies.
On the other side of the world, in the Indus Valley, things progressed slightly differently. Their perspective of life on Earth seems to one that was devoid of the outside realm but of one that incorporated all the celestial bodies in the Universe. Till today, they appreciate significant events of the heavens like the birth of the new moon, the glory of the full moon and specific planetary positioning. Modern science is slowly agreeing to many of their old age believed traditions about the Cosmos and its cyclical manner of doing things. People of the Indian sub-continent continue showing their appreciations to things which are taken for granted in life. A simple example is the festival of Thai Ponggal or Makara Sankranthi which is celebrated during the Indic solstice as the sun enters the 10th house of the Indian zodiac Makara or Capricorn.
As more and more new things are discovered, one cannot fathom but only stand in awe trying to come in terms with how these ancient civilisations, with their rudimentary tools, were able to find things that were literally out of this world.

Kepler-186f is an exoplanet about 550 light-years from the Earth. It is the first planet with a radius similar to Earth's to be discovered in the habitable zone of another star. (Wiki) |
