Principles of Mechanics in the XVIII century

In Module 2 we are going to take a look at the original formulations of two very important principles of physics, namely d'Alembert's and the principle of least action.

D'Alembert's principle is a general statement that, according to its author, solves the general problem of constrained motion of systems of bodies. We will apply this principle to solve the celebrated "center of oscillation" problem.

The principle of least action is a beautiful formulation of mechanics and has many applications in different areas of physics. Several metaphysical issues inevitably emerge with this topic because of the idea that "Nature/God wisely chooses the path that minimizes the action".

The reading material has been divided into two groups, each related to one principle. Don't be scared by the apparent amount files. The texts are short and will help define the specific topic for discussion. And most importantly, don't expect to understand original sources the first time you read them. By the way, remember to submit your questions through Assignment 2: Questions Module 2. They are very important for structuring the teaching and discussion sessions.
