Free Energy and Life

Life is a constant process of chemical reactions, from the simplest reactions of biology to the complex chemical reactions that power our modern society. These reactions are driven by free energy, which is released or absorbed as they occur. Understanding free energy is essential to understanding life, and it plays a crucial role in our daily lives as well.

Free energy can be thought of as the difference between the amount of energy gained or lost during a chemical reaction, and the amount of energy that remains available for other reactions or for storage. It is this free energy that drives the chemical reactions that make up life, and it is also what drives our engines, our computers, and even our brains. Understanding how free energy works and how it can be used is fundamental to our understanding of the world around us, and it is essential for creating a sustainable future for our planet.
