y at West Point, he was the most excellent soldier and kept a record of the best grade——for 25 years. After his graduation, he worked hard every day and became a major general in the Second World War. He served in the Philippines and manded his army to resist the Japanese. However, for the sake of the loss of his air force, he was defeated and in order not to be captived, he left Philippines with all his men captured in Bataan Peninsula. Many Americans cricized him for doing so but he did not bee dejected. Finally he led another army and beat the Janpanese. Obviously, the admiral struggled with the frustration and ultimately succeeded. 4. Breaking the rules amp。 majority [14] Yuan longping is a Chinese agricultural scientist and educator called ―The Father of Hybrid Rice‖. He came up with an idea for hybridizing rice in the 1960s and devoted himself to the research ever since. The biggest problem they faced was having no known method to reproduce hybrid rice in mass quantities. Many people ridiculed him then, because they all thought there was and there would be no means to solve the problem. He happened to find a natural hybrid rice plant that had obvious advantages over others in 1964 and he found another important specie of wild rice for the creation of highyield hybrid rice species in 1970. Ultimately, in 1973, Longping, together with his assistants, was able to establish a plete process of creating and reproducing highyield hybrid rice species. As time goes by, the species have been developed, thus more and more people all over the world can get their stomach full filled, especially the Africans. [15] In 1902, William Maddock Bayliss, a British physiologist, and Ernest H. Starling, also an British physiologist, showed that dilute hydrochloric acid mixed with partly digested food activates a chemical in the duodenum that they called secretin, because it stimulates secretion of pancreatic juice. This marked the discovery of hormones, a term the men coined. However, what did people think before the discovery? Most people thought the phenomenon as a stubborn reflex. It was the continuous experiments and the innovative ideas that made the discovery of secretin. Just imagine that everybody obeyed the rules regarding that as a reflex. Then, the discovery of hormones would be delayed, as secretin was the first hormone to be found. So, the development of biology, pharmaceutics and medical science would be lagged. The importance of breaking the rules can be realized clearly. 5. History amp。 Present [16] Auxins were the first plant hormones discovered. The discovering process is really long and tortuous. First, Charles Darwin started the research. His experiment suggested that the tip of the coleoptile was the tissue responsible for perceiving the light and producing some signal which was transported to the lower part of the coleoptile where the physiological response of bending occurred. Then, Salkowski in 1885, Fitting in 1907, BoysenJensen in 1913, Paal in 1918, Soding and Fritz Went in 1926, all did researches on this project. They all explored independently, but they all studied based on conclusions drew formerly. That is to say, history had play an important role in the discovery of auxins. [17] Chernobyl disaster, the only level 7 event on the International Nuclear Event Scale, occurred on 26 April 1986 at the Chernobyl Nuclear Power Plant in the Ukrainian Soviet Socialist Republic, part of the Soviet Union, now in Ukraine. Four hundred times more fallout was released than had been by the atomic bombing of Hiroshima. As it can be called a nightmare to all human beings, everyone who is enjoying the sweetness of the great use of nuclear energy has waked up. No one knows the reason of the terrible accident, but there were two official explanations: the carelessness of the power plant operators and the problem of control rods. Whatever the reason was, it is an alarm to all nuclear projects. Human have bee more cautious about things connected with nuclear. 6. Education amp。 Knowledge or Practice [18] The law of conservation of mass, also known as principle of mass conservation is that the mass of a closed system (in the sense of a pletely isolated system) will remain constant over time. The law of conservation of mass was first outlined clearly by Antoine Lavoisier in 1789, who is often for this reason referred to as an initiator of modern chemistry. In 1777, Lavoisier conducted an experiment, by using mercury and air, which established a fatal shorting of the phlogiston theory. Absolutely, Lavoisier was not the one of most erudition。 many chemists were more intelligent. But why Lavoisier succeeded? Because others didn’t pay much time on experiments. They believed all what they heard, such as the phlogiston theory. [19] Christopher Columbus was a navigator, colonizer, and explorer whose voyages across the Atlantic Ocean led to general European awareness of the American continents in the Western Hemisphere. Leading three ships out of the Spanish port of Palos on August 3, 1492, he started his adventure to the west to his destination—Asia (the Indies) where the riches of gold, pearls and spice might await. Unfortunately, he did not reach the Asia, which seemed to be a pity for he failed to trade with the Asians and lost a good chance to became a millionaire overnight. However, his practice and efforts didn’t brcame useless in that he found the America. This remarkable incident, which was lately labelled as the greatest discovery of the European history, brought enormous quantity of wealth to the Europe. It was practice that led Columbus famous and European history shinning. [20] James Watt, a Britain inventor, was the most important person of the First Industrial Revolution. After the invention of the steam engine in 1705, many people as we。
