interaction 1 of 3

The Heart of the Matter
Everything we can see, hear, smell, taste, and touch is the result of interactions between our bodies and the physical world. Any relationship we have with other people involves some kind of social interaction with them. History is basically an ongoing story of our collective social interactions. The evolution of every species of life on the planet is the result of long-term, large-scale biological interactions. From grains of sands to galaxies of stars, everything composed of physical matter is the product of emergent interaction. We could even say that everything IS an interaction.
