Statistical mechanics or statistical thermodynamics[note 1] is a branch of physics that applies probability theory‚ which contains mathematical tools for dealing with large populations‚ to the study of the thermodynamic behavior of systems composed of a large number of particles. Statistical mechanics provides a framework for relating the microscopic properties of individual atoms and molecules to the macroscopic bulk properties of materials that can be observed in everyday life‚ therefore explaining

Raymond Williams The twenty months between 1847 and 1848 were decisive for the English Novel. These months marked a new kind of consciousness‚ related to the ‘new and unprecedented civilisation in which it took shape.’ Williams attributes this consciousness to certain major changes which were taking place at this time. He lists the ever expanding influence of the Industrial Revolution‚ the struggle for democracy‚ the growth of cities and towns and Chartism (political and social reforms in the mid

Celestial Mechanics Orbital Maneuvers Earth‚ Moon‚ Mars‚ and Beyond Rodolfo G. Ngilangil Jr. MBA‚ BSAE Impulsive Maneuvers Impulsive maneuvers are those in which brief firings of onboard rocket motors change the magnitude and direction of the velocity vector instantaneously. The position of the spacecraft is considered to be fixed during the maneuvers. This is true for high-thrust rockets with burn times short compared with the coasting of the spacecraft.

Quantum Mechanics ~Three physicists were instrumental: Heisenberg‚ De Broglie‚ and Schrodinger ~Their approach stemmed from De Broglie’s matter wave concept known as "Wave Mechanics" or "Quantum Mechanics" ~ Bohr’s model was inefficient for atoms other than hydrogen or poly-electronic atoms ~ This new approach to a model of the atom focused on the concept of wave functions ~ Since electrons are particles and therefore have wave properties ~ Schrodinger viewed the electron as a standing wave

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

George Washington Carver George Washington Carver was born in 1860 in Diamond Grove‚ Missouri and is one of the most celebrated and respected scientists in United States history as his important discoveries and methods enabled farmers through the South and Midwest to become wealthy and prosperous individuals‚ all due to peanuts. George‚ being the sickly child of two slaves was very frail‚ allowed him not to be able to work in the fields but he did possess a great interest in plants and was very

Sports Mechanics Of Tennis The hitting and subsequent motion of a tennis ball in playing a forehand topspin Abstract The forehand topspin is one of the primary techniques that is utilised in modern day tennis. It has been used to enhance a player’s overall forehand skills that result in the maximising of a players groundstroke power output. This report will analyse the motions the tennis player and tennis ball undergo‚ the forces acting on the player and the ball and lastly‚ the force transformation

Emily Chuang Mechanics of Swimming The crawl‚ also known as freestyle‚ is often regarded as the fastest swimming style. The legs perform a fluttering movement called the flutter kick to propel the body from behind while the elbows take turns moving in a semicircle movement in the swimming direction. One arm relaxes while the other is driven forward. The head is to be kept down in the water when not breathing. To breathe‚ the head turns sideways out of the water and air is to be taken in by the mouth
