The theory of elasticity

|

The theory of elasticity offers us more complicated equations, but which do not differ much from the preceding ones. We still have three unknown functions u, v, w, to which I will add the auxiliary function Θ = du/dx + … Read More

Henri Poincaré: On the Partial Differential Equations of Mathematical Physics – Law of cooling of an isolated solid body in space

|

Suppose we are looking for the law of cooling of an isolated solid body in space. It will be a question of finding a function V satisfying the equation dV/dt = kΔV, and which moreover is given for t = … Read More
