Newton (牛顿) 
One day, Newton was walking and thinking in a garden. He saw that an apple fell from a tree to the ground. It came into his thought that the power of gravity was not limited to a certain distance from earth. This power must extend much further than what people usually thought back then and perhaps retain the moon in its orbit. 

Marie Curie (居里夫人) 
Marie Curie was born in the late 1800s in Poland. The country was torn by wars when she was growing up. Her family called her Manya. Manya’s parents were teachers, and they taught their five children the value of learning. Before Manya turned 11, her eldest sister had died of typhus and her mother had died of tuberculosis. Despite these losses, Manya graduated from high school at 15 with the highest honors. Women were not permitted to study at the University of Warsaw back then. She and her sister had to go to Paris to get their college education. After many years of hard work, she completed her doctoral thesis in 1903 became the first woman to receive a doctorate in France.

Copernicus (1473-1543), great polish astronomer, the founder of modern astronomy, disrupting the founder.

Copernicus in 1473 was born on February 19, Poland, the earthen jarvis riverside city of Aaron. 10 years by anyone, uncle watts harp lode raising. 18 years old, in Krakow in university, professor of mathematics are humanists ChuSiJi Pluto, and conduct the astronomical research volunteers dedicated to.

Copernicus is the main contribution of the heliocentric theory established science, write "natural science in the declaration of independence" celestial circulate. With "1535, four years of Copernicus to complete her time" six volumes of the science of celestial circulate. Complete the theory put forward the heliocentric theory structure in the center of the universe, the sun, and motionless, including the earth around the sun planets are turning. From the sun's recently, followed by mercury, Venus, earth, Mars, Jupiter and Saturn. Only the moon going around the earth. Stars are is far from the sun of a sphere is stationary.

Copernicus to dominate the entire universe took power gives the sun, and each object has its nature is the motion. The heliocentric theory of Copernicus scientifically expounds the view of celestial overthrew the rule, the ptolemaic system for over a thousand years, and the theory of gravity fundamentally denied about god created everything, Christianity is motionless fallacy.

Copernicus startled the rule of the church, be afraid of the opposition and persecution, unwilling to circulate the bodies of publication. On May 24, in1543, Copernicus in his illness, just as he had seen in the published YangShu "celestial circulate.

Although the "sun center said Copernicus by society," the power of religion and the people, even of slander and attack the doctrine of faith propaganda also was brutally crushed and persecution, but of the doctrine of Copernicus, won the final victory. Copernicus and his "object" like a dark night circulate in the twinkling stars, has been a bright ray radiation

哥白尼简介 哥白尼(1473~1543),伟大的波兰天文学家,日心说的创立者,近代天文学的奠基人。   哥白尼1473年2月19日生于波兰维斯瓦河畔的托伦城。10岁丧父,由舅父瓦琴洛德抚养。18岁时进克拉科夫大学,在校受到人文主义者、数学教授布鲁楚斯基的熏陶,抱定献身天文学研究的志愿。   哥白尼的主要贡献是创立了科学的日心学说,写出“自然科学的独立宣言”《天体运行论》。1535年,哥白尼用“四个九年的时间”完成了长达六卷的科学巨著《天体运行论》。完整地提出了太阳结构的理论日心学说:太阳居于宇宙的中心静止不动,而包括地球在内的行星都绕太阳转动。离太阳最近的是水星,其次是金星、地球、火星、木星和土星。只有月球绕地球转动。恒星则在离太阳很远的一个天球上静止不动。   哥白尼把统率整个宇宙的支配力量赋予太阳,而各个天体则都有其自然的运动。哥白尼的日心学说科学地阐明了天体运行的观象,推翻了统治长达一千多年的托勒密体系地心学说,并从根本上否定了基督教关于上帝创造一切,地是静止不动的谬误。   哥白尼慑于教会的统治,怕遭到反对和迫害,迟迟不愿将《天体运行论》公开出版。1543年5月24日,哥白尼在他弥留之际,才在病榻上见到了刚刚出版的《天体运行论》样书。   尽管哥白尼的“太阳中心说”公布后,受到社会上宗教势力和守旧的人们的污蔑和攻击,甚至于信仰宣传这一学说的人也被残酷的镇压和迫害,但是哥白尼的学说,取得了最终的胜利。哥白尼和他的《天体运行论》就像是黑暗夜空中闪烁的巨星,一直放射着璀璨的光芒。

Thomas Edison's Life 

Thomas Alva Edison was born in 1847 in Milan, Ohio. At that time, James Polk was President and Abraham Lincoln was just contemplating running for the legislature. When Edison died in 1931, at the age of 84, Herbert Hoover was President and we were in the middle of the Great Depression. During his lifetime Edison saw the United States engaged in two major wars: the Civil War when he was a teenager, and World War I when he was an adult and appointed to assist the Secretary of the Navy. His inventions had a significant effect upon his times and permanently altered the way in which we live today. Can you imagine life without the electric light? The phonograph and all of its improvements? The motion picture? 

At the age of 12, Edison began work as a "candy butcher" aboard the Grand Trunk Railroad's commuter line between Port Huron, Michigan, where we lived with his parents, and Detroit. He sold newspapers, fruit and candy to the passengers. The train left Port Huron about 7:00 in the morning and returned at 9:00 or 9:30 at night. The trip included a six hour layover in Detroit, during which time he claims to have read "the entire public library." He was an omnivorous reader and loved to experiment with chemicals and machinery. He constantly wanted to investigate how things worked and liked to see if he could make things better. On the train he was allowed a table in an empty baggage car on which to work. He even brought a broken printing press, repaired it and taught himself to print. He may have produced the first newspaper printed on a moving train. Edison began noticing a loss of hearing around this time, which increased throughout his life. 

At that time, telegraph lines often ran parallel to the railroad tracks, and many of the station masters were telegraph operators. Edison was struck by the importance of telegraphy in communication. At home he rigged a makeshift telegraph line between his house and that of a friend so that they could send messages back and forth. Later he and his father would "read" the paper over the telegraph line. Soon he decided to become a real telegraph operator, and with the help of one of the station masters, he learned this skill. He became a telegrapher at the age of 15 and began working for Western Union in such places as Indianapolis, Cincinnati and Memphis. In 1866, at the age of 19, Thomas Edison came to Louisville as an employee of Western Union whose office was then located at the Southwest corner of Main and Second Street. After a brief excursion to New Orleans in August 1866, he returned to work in Louisville. He then found lodging in a shotgun duplex on East Washington Street. 

Edison requested the night shift at work which allowed him plenty of time to spend at his two favorite pastimes -- reading and experimenting. However, it was the latter that eventually cost him his job. One night in 1867, he was working with a battery when he spilled sulphuric acid onto the floor. It ran between the floorboards and onto his boss' desk below. The next morning he was fired. 

While this event marked the end of Thomas Edison's stay in Louisville.

Hawking's key scientific works to date have included providing, with Roger Penrose, theorems regarding singularities in the framework of general relativity, and the theoretical prediction that black holes should emit radiation, which is today known as Hawking radiation (or sometimes as Bekenstein-Hawking radiation).[2] He is a world-renowned theoretical physicist whose scientific career spans over 40 years. His books and public appearances have made him an academic celebrity. He is an Honorary Fellow of the Royal Society of Arts,[3] and a lifetime member of the Pontifical Academy of Science.[4] On August 12, 2009, he was awarded the Presidential Medal of Freedom, the highest civilian award in the United States.[5]

Hawking is the Lucasian Professor of Mathematics at the University of Cambridge (but intends to retire from this post in 2009),[6] a Fellow of Gonville and Caius College, Cambridge and the distinguished research chair at Waterloo's Perimeter Institute for Theoretical Physics.[7]

Hawking has a neuro muscular dystrophy that is related to amyotrophic lateral sclerosis (ALS), a condition that has progressed over the years and has left him almost completely paralysed.
