Reading is a way for us to realize our dreams. Reading a good book can make us clear as water, broaden our horizons, enrich our experience and benefit our whole life. A person's life is a road, and the footprint of trudging on this road has become the trajectory of each of us. It is impossible to walk this road twice, but the scenery we see on the road of life is limited. The book is a telescope, and the book is a bright lamp, which makes us see farther and clearer.
Zhang Heng, a famous scientist and writer in the Eastern Han Dynasty. His birthplace is now Shiqiao, Nanyang County, Henan Province. His grandfather Zhang Kan was a satrap and an upright official. His father died young, and Zhang Heng's family was poor. Rolling has been diligent and studious since childhood, and has long been famous in the village. According to historical records, when he was 10 years old, he was already "proficient in the Five Classics and Six Arts" and could read from memory. He has a wide range of interests, often dabbles in natural science books, and writes well.
One day, Zhang Heng read four poems from a collection of poems, describing the changes of the Big Dipper in the evening of each season: "bucket handle refers to the east, and the world is spring; Guide to barrel handle, it's summer in the world; Bucket handle refers to the west, and the world is autumn; Bucket handle refers to the north, and it is winter in the world. " He thought it was too interesting.
The stars twinkle in the sky, some like dustpans, some like buckets, some like dogs, and some like bears. What are their operating rules? This is simply wonderful. So Zhang Heng drew a sky map according to the content of the poem and referring to other books. Every night, as long as there are no clouds, he silently observes the night sky in front of the star map. How many mysteries are there in the vast starry sky? He observes, records and thinks. His mind is full of all kinds of questions and colorful fantasies. Later, he finally confirmed that the descriptions in those four poems were not accurate enough. In fact, the barrel handle refers to the northeast in early spring and the southeast in late spring.
Galileo was a great Italian physicist and astronomer. His contribution to mechanics is to establish the law of falling body, discover the law of inertia of objects, the law of isochronous vibration and parabolic motion of pendulum, and determine Galileo principle. When studying at the University of Pisa, he was very curious and often asked some questions, such as "Why don't the planets go in a straight line?" Some teachers think he has too many questions, but he never cares and asks questions. Once, Galileo learned that the mathematician Leach had traveled to Pisa, and he prepared many questions to ask Leach. This time, it's great. The teacher took pains to teach, and the students asked endlessly. Galileo quickly learned the knowledge of plane geometry, solid geometry and so on, and profoundly mastered Archimedes' theory on lever and specific gravity of floating body.
Increasing knowledge depends on learning, and enhancing connotation depends on reading.
Riding a horse in Shushan can climb the academic peak; Swim in the sea of books to solve the thirst for knowledge; Stroll in the forest of books and enjoy reading quietly.
