INTRODUCTION WHAT IS QUANTUM? Quantum is the Latin word which means “the smallest possible discrete unit of any physical property”, such as energy or matter. Quantum came into existence in 1900, when the physicist Max Planck used it in a presentation to the German Physical Society. Planck had sought to discover the reason that radiation from a glowing body changes its colour from red to orange and finally to blue when the temperature is raised. He found that by making the assumption that radiation
The branch of physics which deals with mechanics (statics and dynamics) of fluids and the forces on them. Where, fluids include liquids, gases, and plasmas. Fluid mechanics can be divided into two disciplines: Fluid statics: The mechanics of fluids at rest under action of forces. Fluid dynamics: The mechanics of the effect of forces on fluid in motion. 1.2 Fluid Mechanics and society: 1.2.1 Sports:
Introduction Nowadays, cars play a very important role in our lives. Although very complex, they are some of the best facilities the human being has created. Cars are powered by engines. There are many types of engines, according to, the number of strokes, the design of the engine, the fuel used, the method of ignition, the arrangement of the cylinder and the air intake process. For example; four stroke engine, two stroke engine, rotary engine, diesel engine, electric engine, single cylinder engine
