The Hard Sphere Monte Carlo Model performs canonical Monte Carlo simulations of 256 or 500 hard spheres covering the fluid and solid states. The results are analysed through the radial distributions functions from which the equation of state (EOS) is estimated. This is done by fitting a polynomial to the radial distribution functions in order to exrapolate them to the hard spheres distance of contact.

Carnot cycle - The Carnot cycle is a theoretical thermodynamic cycle proposed by Nicolas Léonard Sadi Carnot in 1823 and expanded by in the 1830s and 40s. It can be shown that it is the most efficient cycle for converting a given amount of thermal energy into work, or conversely, creating a temperature difference (e.g. refrigeration) by doing a given amount of work.

Kepler Orbits Hodographs first proved useful in astronomy. If we plot the vectors from the Sun to a planet as it revolves, the locus of their tips is an ellipse. The movement from one arrow to the next gives the velocity. Hamilton showed that, for a planet in a Kepler orbit, the hodograph of the velocity is a circle. This surprising result is easily shown, starting from the polar equation for an ellipse, the orbit of the planet. Hamilton showed it in purely geometric terms (although a lack…
