👉 Tercia is a scientific term used in the field of physics and engineering. It refers to the mathematical representation of a system or object that can be described by a set of differential equations. Tercia is often used in the context of systems with multiple degrees of freedom, such as complex structures like fluids or machines. The concept of tercia was introduced by physicist William Rowan Hamilton in his work "On the Transformation of Heat and Mass into Electric and Magnetic Fluxes", published in 183
