The goal is to study “forces”. Can we quantify “forces”? Consider a wooden block on a smooth horizontal surface. Suppose the wooden block is initially moving from west to east with a velocity ${ \vec{v} . }$ i) Note that if no “force” acts on it, it will continue to move with this velocity indefinitely. ii) Suppose a constant “force” acts on...

Updated: 22/2/25 Ref: “Undergraduate Algebra” by Lang. The goal is to study the structure of finite abelian groups. Let ${ (A, +) }$ be a finite abelian group. We can ask ourselves: Can we express ${ A }$ in terms of its subgroups? Note that for every integer ${ n \in \mathbb{Z} _{> 0} }$ there is a group homomorphism ${ \varphi _n : A \t...
