(Linear) Vector Spaces: A quick review

A linear vector space is a set V that is closed under finite vector addition and scalar multiplication. By closed we mean that after finite vector addition and (or) scalar multiplication of any number of vectors belonging to that space,

Zeroth Law of Thermodynamics

Equation #15: Zeroth Law of Thermodynamics In thermodynamics, being in thermal equilibrium with another body is nothing but a way of saying that the two bodies are at same temperature (definition of temperature). Basically, this law states that if two

The Photoelectric Effect

Equation #14: Photoelectric Effect Albert Einstein was awarded the Nobel prize for his explanation of the photoelectric effect: when light is shone on a metal surface, electrons are ejected. However, the light cannot be of just any wavelength, it has
