3) The air-fuel mixture is then ignited, usually by a spark plug for a gasoline or by the heat and pressure of compression for a Diesel cycle of compression ignition engine, at approximately the top of the compression stroke.

4) The resulting expansion of burning gases then forces the piston downward for the third stroke (power), and the fourth and final upward stroke (exhaust) evacuates the spent exhaust gases from the cylinder past the then-open exhaust valve or valves, through the exhaust port.

One of mankind s earliest and greatest inventions was the wheel. Without it there could be no industry, little transportation or communications, only crude farming, no electric power. Nobody knows when the wheel was invented. There is no trace of the wheel during the Stone Age, and it was not known to the American Indians until the White Man came. In the Old World it came into use during the Bronze Age, when horses and oxen were used as work animals.

At first all wheels were solid discs. The problem to be solved was to make the wheels lighter and at the same time keep them strong. At first holes were made in the wheels, and they became some with iron and then with rubber.

Isaac Newtonis generally regarded as one of the greatest and most famous scientists in history. Newton was an astronomer, physicist, mathematic and philosopher who is known for theorizing and reporting on gravitational force and three laws of motion.

Isaac Newton discovered that white light is made up of a spectrum of colours, that when blender together produce the white light. He showed by use of a prism that white light can be split into a spectrum of colours and then used a second prism to show this spectrum can then be rejoined to produce white light. Newton also theorized that light was composed of particles but had to associate the property of light with waves in order to explain refraction of light.
