Before getting to know what it is physics let us know in advance the characters in the world of physics. maybe some of you already are familiar with these figures, but there are some who are not familiar at all, so let's get acquainted with the experts.
Albert Einstein (born March 14, 1879 - died 18 April 1955 at age 76 years) is a theoretical physicist who is widely regarded as the greatest scientist in the 20th century. He put forward the theory of relativity and also greatly contributed to the development of quantum mechanics, statistical mechanics, and cosmology. He was awarded the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect and "for his services to Theoretical Physics ".Having formulated the theory of general relativity, Einstein became famous throughout the world, an unusual achievement for a scientist. In his old age, his fame exceeded the fame of all scientists in history, and in popular culture, says Einstein is considered synonymous with intelligence or even genius. His face is one of the most known around the world. Albert Einstein, People of the Century (Person of the Century). In 1999, Einstein called the "People of the Century" by Time magazine. To appreciate them, a unit in the photochemical named einstein, a chemical element named einsteinium, and a named asteroid 2001 Einstein.
Thomas Alfa Edisson (1847-1931) is a person who earned the nickname "the Great Inventors. " He began his career as a sender (the operator) the railway telegraph in North America. Kemdian he became the inventor and developer of the objects of human needs that can be patented and sold. In 1870 he was able to sell the results of his creations, namely the telegraph exchanges. His discovery of a phenomenal and highly influential in the field of electricity are the bulb (lamp) of electricity.
James Watt (1736-1819) was a great engineer from the UK (United Kingdom). He successfully created the first efficient steam engine. This steam engine is in fact one of the strengths that led to the Industrial Revolution, particularly in Britain and Europe in general. To appreciate his services, a last name that is used as the name Watt power unit, such as engine power and electric power.
Michael Faraday (1791-1867) Received the nickname "Father of Electricity". He is a person who studies the various fields of science including the effects of strong magnetism on light. This phenomenon led him to find the ideas that became the basis of the theory of magnetic field. He is a member lectures to popularize scientific knowledge in the general population. Rational approach in developing the theory and analyzing the results, very impressive.
Sir Isaac Newton (1642-1727) was a greatest scientist of all time. As a youth he studied at the University of Cambridge (UK) and after graduation he taught at the university. In 1669, he was appointed Professor of Mathematics. He researched various fields of science, such as force, motion, and optics. He successfully argued the three laws of motion. He also wrote several famous books, including Principia and Optics. Her name used to name the unit of force, namely Newton.
Galileo Galilei (1564-1642) was the Italian scientist who is known as one of the first modern scientist. Mathematical description of falling bodies is still valid today. He also made many findings about astrology. Is the first person who saw the craters on the moon with a telescope. Findings conflict with the teachings of the Roman Church at that time. As a result, he was sentenced by a court agam and died while serving his sentence.
Johannes Kepler (1571-1819) was a mathematician and astronomer from Germany who discovered laws of planetary motion (Law I, II, and III Kepler) in a study of the orbit of Mars. He argued that the planets move follows the slightly elongated oval orbit (ellipse), not circular as expected Copernicus. He also found that there is a relationship between the velocity of the planet and the planet's distance from the Sun. Each planet moves fastest when it is at a distance closest to the sun.
Archimedes (287-212SM) was one of the largest engineer and inventor in ancient Greece. He carried out the first scientific study of simple machines and use their knowledge to create a variety of machines. He is the inventor of the Archimedes law that explains why some objects float, float, and sink if put into water or liquid. That said, he found the law was when I saw the water rising at the time he entered the tub.
