Statistical Mechanics: The Ideal Gas

Read Part 1: Equilibrium Systems The Ideal Gas: Boltzmann’s Approach (The Microcanonical Ensemble) Consider a monatomic gas of ##N## non-interacting particles with mass ##m## occupying the volume ##V##. Since the particles of the gas do not interact with each other, it is not difficult to explicitly calculate ##\Omega_{E}##. The position of each particle is constrained to…

Statistical Mechanics: Equilibrium Systems

This is the first of a multi-part series of articles intended to give a concise overview of statistical mechanics and some of its applications. These articles are by no means comprehensive of the entire field, but aim to give a clear line of reasoning from Boltzmann’s equation to non-equilibrium statistical mechanics. It is hoped that…

Getting Started with Solar System Imaging

Some of the most visible objects in the sky are objects within our own solar system: including the Sun, moon, and planets. These objects are generally much brighter than most deep sky objects and in the case of planets, appear much smaller in the sky. These factors have lead amateur astronomers to create specialized imaging…
