This book is intended for students of B Sc degree at university level. This book deals with Computer Programing Thermodynamics and Optics 1 in detail.
Computer programs today simulate physical systems for various purposes, such as realism in games and testing mechanical prototypes before construction. Added with the current trend of increasing processing power, these physical simulations are continually becoming more complicated and elaborate. As such where physics is applicable, programs without these capabilities appear more simple and primitive and thus less desirable compared to programs with these abilities.
Not all programs require the full range of computational capabilities. Most games only require the ability to accurately calculate mechanical processes. Programs like the ones used to test objects need more complex abilities, like calculating the heat given off by the friction between two surfaces. Some programs may even find it desirable to perform pseudo-calculations, calculations based upon physics yet tweaked to achieve a more desirable behavior, or they may just represent a very narrow range of processes that can occur.
When programming physics, various different mechanisms of physics, including branching decisions such as collisions between objects, gravity and any other exertional forces taking effect upon objects present, along with various other elements depending upon the given situation, need to be taken into account and compensated for accordingly.
Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work. The behavior of these quantities is governed by the four laws of thermodynamics, irrespective of the composition or specific properties of the material or system in question. The laws of thermodynamics are explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, chemical engineering and mechanical engineering.
Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Nicolas Léonard Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scottish physicist Lord Kelvin was the first to formulate a concise definition of thermodynamics in 1854 which stated, “Thermo-dynamics is the subject of the relation of heat to forces acting between contiguous parts of bodies, and the relation of heat to electrical agency.”
The world around us is bathed in light, providing the input to our eyes with which we try to make sense of the surroundings. However, light is not limited to the narrow band of wavelengths we can see, but extends across a broad spectrum including long wavelength radio waves down to short wavelength x-rays and gamma-rays.
