Any object away from its fixed position will come back to its original position.Falling body doesn't depend on its mass.Descartes' mechanical methodology 笛卡尔的机械主义方法论French philosopher, physicist, mathematicianFather of modern philosophy: DescartesFather of modern science: GalileoHis main achievements rest with his philosophy. To him, man or universe is a machine. The influence of his mechanical philosophy is profound, which later became the basic thinking mode of scientists after him. Lecture 8 Newton's era★His virtue of modesty:If I see farther than others, it is because I stand on the shoulders of giants.★Newton's laws of motion:1.Every object is in a state of rest or in a uniform linear motion ,unlessexerted by an external force.2.The acceleration and the external force of the object are in the rightproportion, the direction of the accelerating velocity and that of the external force are the same.3.There is always an equal counteraction opposite in direction, for everyaction, Newton lays claims to the third law as his discovery. Conclusions about optics: sunlight and the ordinary white light are made up of lights of its own color. These colors are inherent in nature, not caused by prism.★Newton's contributions:1.H has established mechanics as an independent discipline by laying thefoundation for the axioms of the mechanics themselves.通过奠定力学的公理基础把力学确立为一门独立学科。

Some history
Charge was discovered by the Ancient Greeks (about 600BC) who found that rubbing fur on various substances, such as amber, would build up an electric charge imbalance. The Greeks noted that the charged amber buttons could attract light objects such as hair. The Greeks also noted that if they rubbed the amber for long enough, they could even get a spark to jump. The word electricity derives from ηλεκτρον, the Greek word for amber.

Translation in China
During Zhou Dynasty, there was one word for translator in each direction.“东方曰寄,南方曰象 ,西方曰狄,北方曰譯”。 譯 became the only word for "translator" because in the Han Dynasty, most translation was done with the north. Translation developed through translations of Buddhist scriptures, especially during Sui Dynasty and Tang Dynasty.
Key figures in the field of translation
• 鸠摩罗什(Kumarajiva 344~413): 佛经翻译 意译派代表人物,译经思想影响深远,开 创了我国古代佛经翻译的新时期。
• 真谛(拘那羅陀, Paramartha,499-569): 印度佛教学者,译有49部经论,其中尤以 《摄大乘论》的翻译出名,对中国佛教思 想有较大的影响。
