Our actions enable us to find out about the world. Full real life provides a sense of all we have to do. Evolution in Africa for 7 million years involves sun, atmosphere, water, earth and interaction with all human groups. Experience of Himalayas and Pacific Ocean excites a deep response as early cultures progress in Southeast Asia.
Polynesian navigators use swells, currents, winds and clouds
Chinese astronomers keep a full record of events in the sky from 2,000 BCE. For the Indus Valley civilisation stars indicate all that is possible in human life. From the Central African Rwenzori Mountains of the Moon the Nile River flows for 4,000 miles on the banks of which ancient Egyptians build from desert earth rock temple column blocks architecture up towards the stars. As we come to North African Mediterranean climes seafarers from Arabia, Levant, Anatolia and Hellas make from experience materialist knowledge of a natural world.
From full life experience to knowledge of physical realities
African Arabian travelling scholars bring the researches of Alexandria and Athens to Renaissance Europe. It is here that Galileo observes a swinging chandelier in Pisa cathedral which he times with his own pulse to find that however high it swings its periods of oscillation are equal demonstrating that acceleration to the earth is really energy change. The fall of an apple for Newton is like a planet moving around the sun with its mass and motion energy changes of the whole universe. This representation involves all that sense experience detects is physically happening.
Sense experience is all that is physically happening
Quantal, electronic, atomic and nuclear discoveries open a 20th century of science advances. Experiments in 1949 demonstrate that quanta correlate as fundamental physical realities. All that involves matter and mass as galaxies clusters rotate comes from wider events of the cosmos. It is energies interchanges of the whole universe that come together through quanta matter mass elementary particles that are the basic physical realities functions.
