👉 Plastochrone is a concept in theoretical physics that describes how a material's elasticity changes with temperature. It was proposed by physicist Hans von Buechler and later by his student Ludwig Boltzmann, who used it to explain the behavior of gases under pressure. In simple terms, the term "plastochrone" refers to an object or system undergoing a change in its shape due to temperature. This is because when a material changes from a solid state to a liquid state at higher
