These four papers were major contributions to the foundation of modern physics. They revolutionized science's understanding of the fundamental concepts of space , time , mass , and energy. Because Einstein published these remarkable papers in a single year, is called his annus mirabilis miracle year in English or Wunderjahr in German. The first paper explained the photoelectric effect , which was the only specific discovery mentioned in the citation awarding Einstein the Nobel Prize in Physics. The third paper introduced Einstein's theory of special relativity. These four papers, together with quantum mechanics and Einstein's later theory of general relativity , are the foundation of modern physics.

In: Science. The Photoelectric Effect: How Solar Electricity is Generated Solar energy is an evolving source of power that gradually is becoming more popular to be used as a viable replacement for or for at least some of the commonly used power sources around the world today, such as coal, natural gas, and nuclear power. Because many scientists of The Industrial Revolution strongly believed that fossil fuels such as coal would eventually run out, some of them looked for different ways to generate energy. Thus, dating far back to the early s, power generation through the photoelectric and photovoltaic effects were discovered. Solar energy is generated by solar panels, which are composed of individual solar cells or photovoltaic cells that absorb light from the sun - the light absorbed is then turned into electricity. The absorption of light can be attributed to two processes, one being the photoelectric effect, and the other the photovoltaic effect.

History of Solar Power

Please join StudyMode to read the full document. The photoelectric effect is when a clean metal surface emits electrons after light, especially ultraviolet, has been shone on at it. This happens because of a process called photoelectric emission whereby a single photon package of electromagnetic energy, called a quantum, is absorbed by metal surfaces. This energy is then transferred to one single electron which can then be released by the metal and that released electron is known as a photoelectron. The effect was first absorbed by German physicist Heinrich Hertz in and another discovery he discovered said that metal surfaces where also more likely to emit sparks if they had also been illuminated.

Although Einstein wrote five fundamental papers in , only one - the article showing that light consists of discrete quantum particles - was truly revolutionary, argues John S Rigden. In less than seven months, Einstein wrote five history-making papers. The creative outpouring that Einstein exhibited in stands alone in the history of physics. After years of sweeping advances in the subject since then, the content of these papers remains at the bedrock of our discipline see Five papers that shook the world Physics World January pp
