A person who never made a mistake never tried anything new.....Albert Einstein

  Albert Einstein was a German-born theoretical physicist best known for developing the theory of relativity. Einstein also made important contributions to quantum theory. His mass–energy equivalence formula E = mc², which arises from special relativity, has been called "the world's most famous equation". He received the 1921 Nobel Prize in Physics for "his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". In year 1905, sometimes described as his annus mirabilis (miracle year), he published four groundbreaking papers. In them, he outlined a theory of the photoelectric effect, explained Brownian motion, introduced his special theory of relativity, and demonstrated that if the special theory is correct, mass and energy are equivalent to each other. In year 1915, he proposed a general theory of relativity that extended his system of mechanics to incorporate gravitation. A paper that he published the following year laid out the implications of general relativity for the modeling of the structure and evolution of the universe as a whole. It introduced the cosmological constant and is further regarded as the first step in the field of modern theoretical cosmology. In year 1917, Einstein wrote a paper which introduced the concepts of spontaneous emission and stimulated emission, the latter of which is the core mechanism behind the laser and maser, and which contained a trove of information that would be beneficial to developments in physics later on, such as quantum electrodynamics and quantum optics. In the middle part of his career, Einstein made important contributions to statistical mechanics and quantum theory. Especially notable was his work on the quantum physics of radiation, in which light consists of particles, subsequently called photons. With physicist Satyendra Nath Bose, he laid the groundwork for Bose–Einstein statistics. For much of the last phase of his academic life, Einstein worked on two endeavors that ultimately proved unsuccessful. First, he advocated against quantum theory's introduction of fundamental randomness into science's picture of the world, objecting that "God does not play dice". Second, he attempted to devise a unified field theory by generalizing his geometric theory of gravitation to include electromagnetism. As a result, he became increasingly isolated from mainstream modern physics. Many things are named after him, including the element Einsteinium. In year 1999, he was named Time's Person of the Century.

  This quote is from a successful individual, Albert Einstein. Ever know that he tried experiments many times, but failed, just like Thomas Alva Edison. But anyway, he did not give up. He tried his own best. At last, he learned and gained knowledges and experiences. I, like you all, make mistakes before. Is there anyone who don't make mistakes before? Nope. Mistakes are like challenges. People not really need to be 100% correct, like god. If accidentally make mistake, or face any challenges, don't run away, or cry like a baby. Know where it goes, and fix it, you will earn your rewards.......................
