Yin and Yang

Yin and Yang is a form of Technology and Culture.

Description
Yang is the light, Yin is the shade. Without one, there cannot be the other. Yang and yin are the opposing but complementary forces that permeate nature. Hot and cold, life and death, fire and water, action and passivity, male and female. These ideas underpin most of Chinese thought.
