Human Chemistry…The Study Of How People Chemically React To One Another

Ever been around a person or group of people that you felt you just didn’t mix well with? or transversely been drawn to someone or a group?  Well there may be an actual chemical reason.  Human Chemistry, the study of how people chemically react to one another, is a branch of the science of human nature. According to Jean Sales a French Philosopher in 1789, the atomic definition of a person is a “human molecule”. According to this view, human chemistry is the quantitative study of reactions between human molecules and the structures they form.

The Ingredients for connection and repulsion


“Social chemistry—the study of the mutual attraction and repulsion of equivalent human molecules is how American historian Henry Adams described Human Chemistry later in 1885.

According to the first Human chemist, Greek Philosopher Empedocles (495-435 BC). “People who love each other mix like water and wine; people who hate each other segregate like water and oil.”

The Human Molecule Chemical Equation

Defining and representing human molecules as chemical species A or B, basic human reactions, such as couple formation (combination reaction) or relationship breakup (bond dissolution), take the form of simple chemical equations, such as:

A + B →  AB (Bond Formation)   (or)  AB →  A + B ( Bond Dissolution)

An additional aspect is the quantum mechanical definition of the human chemical bond A≡B between two human molecules, such as the connection in an intimate romantic relationship.-

A Deeper Look…

Human Chemistry views each individual person as a large atomic structure, or single abstract molecule that has been synthesized over BILLIONS of years, which react with each other in the form of daily complex mechanistic chemical reactions.

Over all if a large chemist were looking down on earth, ash though the surface of the earth were a test-tube for his studies, the chemist would view humans to be little molecules reacting together forming products!
