Today's world is filled with technologies, chemistry projects, social projects but nevertheless now were following the concept of their stage or dais. The only changes are happened honestly: their drama was performed in open air and today it can be inside covered area; in those days drama was performed only evening these days we can easily enjoy three times per day; there were no means of light facilities today it is totally computerized; that point dais was fixed and now it is revolving. Next to contact breaker, spark plug is among the most weakest part of the ignition system. It is mounted within the combustion chamber from the engine, where working conditions are- severe. During peak combustion conditions the temperature inside the combustion chamber in the modern car engine may be around 2500 ºC and the pressure about 7 Mpa. Moreover a spark plug can also be exposed to thermal and load cycling fatigue on account of sudden changes in temperature and pressure-from the high temperature of burnt gas on the relatively low temperature with the air/fuel mixture and from the ruthless during the time of explosion from the air/fuel mixture to low pressure during induction. In addition, the spark plug needs to endure high voltage, mechanical vibration along with the corrosive atmosphere of combustion gages. A modern spark plug posseses an economical life of about 10,000-16,000 km. Colorful animal world is so interesting for humankind to explore. It is the diversity of genres with various life spans which leads to the ecosystem balance. It has been searched that the Galapagos tortoises can live during 177 years due to good adaptation for the environment; however, there are many life spans that are shortened by natural features. What animals have the shortest life expectancy? Let's discover!
