Only by obeying nature can we master nature. Bacon (UK)

The sea of truth, let all undiscovered things lie before my eyes, let me explore. -Newton (UK)

6. The benefits of fallacy are temporary, while the benefits of truth are permanent; When truth has shortcomings, these shortcomings will soon be eliminated, and fallacies always go hand in hand with fallacies. -Diderot (France)

7. Anyone who takes a rash attitude towards the truth in small matters is also untrustworthy in big matters. -Einstein (USA)

8. Man's bounden duty is to be brave in exploring the truth. -Copernicus (Poland)

10. Scientific inspiration is by no means waiting. If there is any accidental opportunity for scientific discovery, then this "accidental opportunity" can only be given to educated people, people who are good at independent thinking, people who have perseverance, and not to lazy people. -Hua (China)

Examples of life

When Zhang Haidi was 5 years old, he suffered from spinal hemangioma and paraplegia. Therefore, she has never been to school. From an early age, she began to teach herself knowledge with tenacious perseverance. She taught herself specialized courses in primary schools, middle schools and universities. When Zhang Haidi/KLOC-was 0/5 years old, he was sent to a poor mountain village in Shen County, Liaocheng with his parents. But she is not afraid of hard life, but dedicated her youth with optimism. There, she taught the children in the village primary school, overcame all kinds of difficulties to learn medical knowledge, and enthusiastically treated the villagers with acupuncture. During her stay in Shenxian County, she treated more than 10,000 people for free and was warmly praised by people.

From 65438 to 0983, Heidi embarked on the road of literary creation.

Translation works: seaside clinic, Rebecca in the new school, Little Miller's Journey, modoc-the true story of an elephant, etc. Her works have aroused strong repercussions among social teenagers, and the novel Dream in a Wheelchair has been published in Japan and South Korea.

Stephen Hawking (1942-) is one of the great men with international reputation in this century. He is 63 years old and was born on the anniversary of Galileo's death. He is a professor of applied mathematics and theoretical physics at Cambridge University, and also the most important general relativity and cosmologist in contemporary times. In 1970s, together with Penrose, he proved the famous singularity theorem, for which they jointly won the Wolff Prize in Physics of 1988. He is therefore known as the most famous scientific thinker and the most outstanding theoretical physicist in the world after Einstein. "He also proved the area theorem of black holes. Hawking's life is very legendary, and he is one of the most outstanding scientists in history in scientific achievements. His position is the highest professorship in the history of Cambridge University, that is, Lucasson Professor of Mathematics once held by Newton and Dirac. He holds several honorary degrees and is a member of the Royal Society. He suffers from Luger's disease (amyotrophic lateral sclerosis) and has been in a wheelchair for 20 years. However, he was physically and mentally disabled and turned it into an advantage, overcoming his disability and becoming a supernova in the international physics community. He can't write or even read clearly, but he transcends relativity, quantum mechanics and the Big Bang theory and enters the "geometric dance" to create the universe. Although he was so helpless in a wheelchair, his thoughts traveled brilliantly in the vast space and time, and solved the mystery of the universe.

Professor Hawking is a modern popular science novelist. His masterpiece is A Brief History of Time written in 1988, which is an excellent astronomical popular science novel. The author's imagination is rich, his ideas are wonderful, his language is beautiful and his words are meticulous, which is even more surprising. The outside world, the future changes are so magical and wonderful. This book has a cumulative circulation of 25 million copies and has been translated into nearly 40 languages. 1992 The film of the same name cost 3.5 million pounds. Hawking firmly believes that the basic ideas about the universe and the origin of life can be expressed without mathematics, and the world should be able to understand his profound theory through the audio-visual media such as movies. This book is a popular reading about exploring the nature of time and the frontier of the universe. It is the most important classic work about the scientific thought of the universe, which has changed the concept of the universe. As soon as this book was published, it caused great repercussions all over the world. A Brief History of Time is a landmark book for readers who prefer words to equations. She is good at being a contributor to human thoughts. This is a book that pursues knowledge infinitely and explores the essence of time and space.

Mystery of golden crown

King Hennon asked the goldsmith to make a pure gold crown for him. After it was done, the king suspected that the craftsman had mixed silver into the crown, but the crown was as heavy as the pure gold given to the goldsmith at the beginning. Did the craftsman play tricks? The problem of trying to test the authenticity without destroying the crown not only stumped the king, but also made the ministers look at each other. Later, the king gave it to Archimedes. Archimedes thought hard about many methods, but all failed. One day, he went to the bathhouse to take a bath. Sitting in the bathtub, he saw the water overflowing and felt his body being gently pulled up. He suddenly realized that he jumped out of the bathtub and went straight to the palace without clothes on. He shouted "Eureka" and "Frica" all the way. It turns out that if the crown is put into water, the amount of water discharged is not equal to the same weight of gold, and it must be mixed with other metals. This is the famous law of buoyancy, that is, an object immersed in a liquid is subjected to upward buoyancy, and its size is equal to the weight of the liquid discharged by the object. Later, this law was named Archimedes principle.

Patriot Archimedes

In his later years, the Roman army invaded Syracuse, and Archimedes instructed his compatriots to make many weapons for attack and defense. When Marcelle Sai, the leader of the invading army, led a group of people to attack the city, he designed a trebuchet to beat the enemy out of the water. His crane with iron claws can lift the enemy ship, turn it upside down and throw it into the depths of the sea. Legend has it that he also led the people of Syracuse to make a huge concave mirror, which focused the sunlight on the approaching enemy ship and made it burn. Roman soldiers have been frightened by such frequent blows. They are afraid of everything. As soon as they saw the rope or wood thrown from the city, they exclaimed "Archimedes is coming" and then ran around. Roman troops were kept out of the city for three years. Finally, in 2 12 BC, the Romans took advantage of the slight relaxation of the ancient city of Syracuse to attack on a large scale and break into the city. At this time, Archimedes was studying a profound math problem. A Roman soldier broke into the house and trampled on his drawing with his foot. Archimedes argued with him angrily. The cruel soldier didn't listen, but with a flick of his knife, a talented science superstar fell.

Jian Zhen became a monk at the age of 18 and studied Buddhism diligently. In 742, Japan sent Rong He and Pu Zhao to China to invite monk Jian Zhen to preach in Japan.
