## Nonlinear Dynamics: An introduction

This post is the first in the series “Nonlinear Dynamics”. (The subject of nonlinear dynamics builds up on Differential Equations and Classical Mechanics. You may want to brush up on those) Dynamical Systems Let me start with an example. We take

## Bernoulli’s Equation

Equation #16: Bernoulli’s Equation Essentially a restatement of the law of conservation of energy, this equation means that in a given steady irrotational flow of fluid the pressure and velocity at any point is related. The term “v2/2″ denotes kinetic

## 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
