In both science and in technology, a battery is used as a type of device that is used to store energy, making it available for use in an electrical form. They consist of electrochemical devices, including one or even more galvanic cells. Baghdad Batteries are thought to be the first known in history, dating back from sometime between the years of 250 BCE and 640 BCE. The modern battery began with the Voltaic pile, which was developed by Alessandro Volta, an Italian physicist, in 1800. As of a 2005 estimate, the battery industry generates, no pun intended, around 48 billion dollars in annual sales. Batteries can be divided into two main categories, rechargeable batteries and non-rechargeable, or disposable, batteries. Disposable batteries are also known as primary cells. They are intended for a one time use only, to be used until the chemical changes used to induce its electrical current supply have been finished. Their common usages include smaller, more portable devices that have either a low current drain or are used away from any...

Human beings are emotional animals. At the same time we analyze and think with our head. In any given situation, heart or head does not always guide our response. It may be both heart and head that determine our response. For example, you may find one of your co-workers making major blunders. You will not complain about him her to senior management without considering the emotional break down that may be suffered by him her if the senior management sacks them. Your heart will add its compassion to your logic and you will decide accordingly. All of us don t react similarly in a given situation. Some of us are emotional animals while some of us are prominently analytical thinkers. When you read biographies of some of the greatest historical figure, you will find that they had a good mix of both heart and head, except few brutal ones who only thought with head and had no heart. What is your mix. Are you more of heart or head. Please quiz yourself about this. Are you driven by cold logic or your heart makes you act in most of the situations...

Why are so many people drawn to lighthouses. There are probably a lot of different reasons. Maybe it is because lighthouses are found in some of the most beautiful places on earth, many on rugged coast lines dotted with trees, others along the sandy beaches, still others on reefs or rocks out in the ocean. To some, lighthouses appeal to their nostalgic or artistic senses since many of the lighthouses are some of the most historical structures to be found in the United States today. Yet it may be that they are drawn to the lighthouses due to the multitude of heroic rescues associated with them. It does not matter, whether warning mariners of danger or aiding them in finding safe passage into the harbor, lighthouses today as in the past, stand as beacons of safety and security. The lighthouse mystic is a part of our past, present, and future. Let their lights forever shine. Many years ago, people lived in a primitive way, hunting and growing their own food. Eventually, they decided to explore the water in a boat in search of what the sea...

Since the very foundation of this country the groups that have been most disenfranchised and most often attacked were those who would fight for equality. Though the abolitionists and the feminists eventually won their battles, the most often attacked political group and those who completely lost their battle in America were those who fought for economic equality. Socialism and Communism are seen as bad words in today s America and several times during the 20th Century it was seen as completely just to jail someone for their political beliefs and for belonging to a particular party. During the McCarthy era it was seen as just to exile such people from society entirely. Even though McCarthyism ended, there is no longer a Socialist party within America and the word seems to exist only as weapon for Conservatives to use against Liberals, the same as calling a Black man a nigger. Yet this disenfranchisement, this exile, this transformation of a political idea into a naughty word is completely unconstitutional. Perhaps the first attack on such...

As Humans we have three skins. First, our fleshly skin which is breathable. It transpires. Takes in moisture and lets out moisture. Our skin which is the largest organ of our body is a marvelous creation, and one we need to learn from. Our skin offers us protection and comfort. It offers us comfort precisely because of its ability to breathe. Our second covering is our clothing. Again our clothing which offers us protection and comfort is breathable. As a rule people do not prefer wearing plastic or vinyl but rather natural fibers because they breathe. Our Third environment is our home. We learn even from people of antiquity that homes should offer not only protection but be breathable. Why should we expect our walls to be made of plastic. That may offer protection but not comfort. It is no secret that many in the wall finishes industry are speaking against vinyl wall covering specifically because they form a moisture barrier in the wall, not allowing the wall to breathe and creating a situation in which mold is not only inevitable but...
