Early Christian and Byzantine Architecture
1. The architecture of Byzantium, or Eastern Roman Empire, was the culmination of Early Christian architecture. This style can be traced back to the period after 330 BC. The art characteristic of the developed Byzantine Empire had enormous influence on both East and West, spread widely and lasted throughout the Middle Ages until the fall of Constantinople to the Turks in 1453.
2. The dominant Byzantine art was architecture. It was characterized by round arches, elaborate columns, richness in decorative elements and colour. But the chief contribution of the Byzantine style to the architecture of the world was large pendentive-supported dome. Brick was the main material used for the construction of Byzantine churches. It was covered externally with plaster and internally with thin marble facing and mosaics above.
3. The Byzantine style reached a high point in the reign of the Emperor Justinian (527-565). He built and rebuilt 26 churches, many hospitals, bridges aqueducts, and fortress. The outstanding masterpiece of Byzantine church architecture is Hagia or Saint Sophia in Constantinople (now Istanbul). Hagia Sophia remained unique and no attempts were thereafter made by Byzantine Builders to emulate it. Its chief feature is the huge dome, approximately 32.6 m in diameter, rising 56 m above the floor. It’s carried on pendentives. There are also half-domes at two ends which are, in turn, carried by smaller semidomed exedrae. The interior surface of the edifice is richly decorated.

How Batteries Work
1. An electrical battery is a combination of one or more electrochemical cells, used to convert stored chemical energy into electrical energy. Since the invention of the first Voltaic pile in 1800 by Alessandro Volta, the battery has become a common power source for many household and industrial applications.  
2. Inside the battery itself, a chemical reaction produces the electrons. The speed of electron production by this chemical reaction (the battery's internal resistance) controls how many electrons can flow between the terminals. Electrons flow from the battery into a wire, and must travel from the negative to the positive terminal for the chemical reaction to take place. That is why a battery can be stored on a shelf for a year and still have plenty of power. Once you connect a wire, the reaction starts.
3. Batteries may be used once and discarded, or recharged for years as in standby power applications. Miniature cells are used to power devices such as hearing aids and wristwatches; larger batteries provide standby power for telephone exchanges or computer data centers.
