History Of Islam

History Of Islam When Charles Martel defeated the Muslims in Spain and stopped their advance into greater Europe (Ahmed 67)0, he most likely did not know just how much of an effect his victory had on the history of not only Europe, but of the known world. The fact that Islam may have overtaken the rest of the world had it not been for that crucial battle attests to the strength of this relatively new religion. If the strength of the religion is dependent upon those who start it, then it is important to analyze the life of the one key character in history who began it all. That key character is Muhammad, the man that is known as the first and last true prophet of Islam. Muhammad, the great prophet and founder of Islam, was born in 570 AD, and was soon an orphan without parents. He was raised by a family of modest means and was forced to work to support himself at an early age. He worked with a travelling caravan as a driver and at

Nanotechnology essay

Nanotechnology: Immortality or total annihilation? Technology has evolved from ideals once seen as unbelievable to common everyday instruments. Computers that used to occupy an entire room are now the size of notebooks. The human race has always pushed for technological advances working at the most efficient level, perhaps, the molecular level. The developments and progress in artificial intelligence and molecular technology have spawned a new form of technology; Nanotechnology. Nanotechnology could give the human race eternal life, or it could cause total annihilation. The idea of nanotech was conceived by a man named K. Eric Drexler (Stix 94), which he defines as "Technology based on the manipulation of individual atoms and molecules to build structures to complex atomic specifications (Drexler, "Engines" 288)." The technology which Drexler speaks of will be undoubtedly small, in fact,

 

SOLAR ENERGY -- THE ENERGY OF THE FUTURE?

SOLAR ENERGY -- THE ENERGY OF THE FUTURE? About 47 per cent of the energy that the sun releases to the earth actually reaches the ground. About a third is reflected directly back into space by the atmosphere. The time in which solar energy is available, is also the time we least need it least - daytime. Because the sun's energy cannot be stored for use another time, we need to convert the suns energy into an energy that can be stored. One possible method of storing solar energy is by heating

Solar cells

Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still

the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and

unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear out. It is no wonder that one marvels on how such a device would
