We sense the world through our actions. What we find makes our full real life experience. Our comprehension of the universe comes from this. We add to our knowledge as we develop what we do.
To start with we sense the natural world. As human life develops all of our actions come to involve the world around us. Ancient civilisations initiate astronomical observations to provide guidance for human affairs. Commercial activity on earth is directed by knowledge of the stars.
The African Arabian civilisation develops astronomical observation. Around the world cultures develop through seafaring transactions. Circa 1000 CE physical science advances via human efforts exerted across hammered earth terrain. Civilisation preserves advances in optics and astronomy and affairs of the Near East transmit scientific knowledge to Europe.
The stability of renaissance Europe provides initiative for human involvement with the planets and stars to develop. The enlightenment sees material and planetary science able to comprehend dynamics of masses. Cooperative human endeavour through the industrial revolution aligns physics and astronomy in practical involvement with earth and planets. In the 20th and 21st centuries it becomes clear human actions involve energies of the universe.
