Renaissance Art History essays

Renaissance Art History essays The transition from the Middle Ages to modern times between the fourteenth and sixteenth centuries is referred to as the Renaissance, which originated in Florence, Italy. During this time, Italian artists studied the art of the Greeks and Romans, whom they learned a lot from. The Italian artists had hopes of rekindling the spirit behind Greek and Roman cultures, referred to as classical antiquities. The Renaissance artists were the main spark behind the rebirth of both cultures. Renaissance humanists emphasized the classical studies along with the restudy of the culturalist ideals and forms. With the combination of wealth and dominant connections, the Medici family soon began to make their presence known early in the fifteenth century of the renaissance. The Medici family were among the more powerful supporting leaders of humanism. The Medicis influence along with few members of the house that supported patrons of the arts, literature, and learning, are what helped establish Florence as one of the richest repositories in Europe. During the high Renaissance, art became a way for some to make a living. Artists were creating ways to show their humanistic ways and views. The same artists could often times get a better understanding of the renaissance in their own paintings. One important artist of the high Renaissance is Leonardo da Vinci, who presents the High renaissance dichotomy better than any other artist of that time period. Leonardo worked for a military weapon engineer, but still managed to continually paint creations of ideal beauty during the high renaissance. After his brief job with the military weapon engineer, Leonardo attained a better understanding of the evil nature of a man. Another important artist is Raphael, who composed the balance and harmony of the high Renaissance. Throughout the Renaissance time period, Raphael designed many churches, palaces, and even mansions. His interpretation of classi...

The Life and Achievements of Albert Einstein

The Life and Achievements of Albert Einstein Legendary scientist Albert Einstein (1879 - 1955) first gained worldwide prominence in 1919 after British astronomers verified predictions of Einsteins general theory of relativity through measurements taken during a total eclipse. Einsteins theories expanded upon  universal laws formulated by physicist Isaac Newton in the late seventeenth century. Before EMC2 Einstein was born in Germany in 1879. Growing up, he enjoyed classical music and played the violin. One story Einstein liked to tell about his childhood was when he came across a magnetic compass. The needles invariable northward swing, guided by an invisible force, profoundly impressed him as a child. The compass convinced him that there had to be something behind things, something deeply hidden. Even as a small boy Einstein was self-sufficient and thoughtful. According to one account, he was a slow talker, often pausing to consider what he would say next. His sister would recount the concentration and perseverance with which he would build houses of cards. Einsteins first job was that of patent clerk. In 1933, he joined the staff of the newly created Institute for Advanced Study in Princeton, New Jersey. He accepted this position for life, and lived there until his death. Einstein is probably familiar to most people for his mathematical equation about the nature of energy,  E MC2. E MC2, Light and Heat The formula  EMC2 is probably the most famous calculation from Einsteins special theory of relativity. The formula basically states that energy (E) equals mass (m) times the speed of light (c) squared (2). In essence, it means mass is just one form of energy. Since the speed of light squared is an enormous number, a small amount of mass can be converted to a phenomenal amount of energy. Or if theres a lot of energy available, some energy can be converted to mass and a new particle can be created. Nuclear reactors, for instance, work because nuclear reactions convert small amounts of mass into large amounts of energy. Einstein wrote a paper based on the  new understanding of the structure of light. He argued that light can act as though it consists of discrete, independent particles of energy similar to particles of a gas. A few years before, Max Plancks work had contained the first suggestion of discrete particles in energy. Einstein went far beyond this though and his revolutionary proposal seemed to contradict the universally accepted theory that light consists of smoothly oscillating electromagnetic waves. Einstein showed that light quanta, as he called the particles of energy, could help to explain phenomena being studied by experimental physicists. For example, he explained how light ejects electrons from metals. While there was a well-known kinetic energy theory that explained heat as an effect of the ceaseless motion of atoms, it was Einstein who proposed a way to put the theory to a new and crucial experimental test. If tiny but visible particles were suspended in a liquid, he argued, the irregular bombardment by the liquids invisible atoms should cause the suspended particles to move in a random jittering pattern. This should be observable through a microscope. If the predicted motion is not seen, the whole kinetic theory would be in grave danger. But such a random dance of microscopic particles had long since been observed. With the motion demonstrated in detail, Einstein had reinforced the kinetic theory and created a powerful new tool for studying the movement of atoms.
