What has modified out traditional view of Galileo inrecent times？In his own lifetime Galileo was the centre of violent controversy； but the scientific dust has long since settled，and today we can see even his famous clash with theInquisition in something like its proper perspective. But，in contrast， it is only in modern times that Galileo has become a problem child for historians of science.The old view of Galileo was delightfully uncomplicated.He was， above all， a man who experimented： who despisedthe prejudices and book learning of the Aristotelians， whoput his questions to nature instead of to the ancients， and who drew his conclusions fearlessly. He had been the first to turn a telescope to the sky， and he had seen there evidence enough to overthrow Aristotle and Ptolemy together. He wasthe man who climbed the Leaning Tower of Pisa and dropped various weights from the top， who rolled balls down inclined planes， and then generalized the results of his many experiments into the famous law of free fall.But a closer study of the evidence， supported by adeeper sense of the period， and particularly by a new consciousness of the philosophical undercurrents in the scientific revolution， has profoundly modified this view ofGalileo. Today， although the old Galileo lives on in many popular writings， among historians of science a new and more sophisticated picture has emerged. At the same time our sympathy fro Galileo's opponents ahs grown somewhat. His telescopic observations are justly immortal； they aroused great interest at the time， they had important theoretical consequences， and they provided a striking demonstration of the potentialities hidden in instruments and apparatus. But can we blame those who looked and failed to see what Galileo saw， if we remember that to use a telescope at the limit of its powers calls for long experience and intimate familiarity with one's instrument？ Was the philosopher who refused to look through Galileo's telescope more culpable than those who alleged that the spiral nebulae observed with Lord Rosse's great telescope in the eighteen-forties were scratches left by the grinder？ We can perhaps forgive those who said the moons of Jupiter were produced by Galileo's spyglass if we recall that in his day， as for centuries before， curved glass was the popular contrivance for producing not truth but illusion， untruth； and if a single curved glass would distort nature， how much more would a pair of them？MICHAEL HOSKIN Galileo Reborn from The ListenerNew words and expressions 生词和短语controversy n. 争议，争论dust n. 纠纷，骚动clash n. 冲突Inquisition n. （罗马天主教的）宗教法庭perspective n. 观点，看法despise v. 蔑视generalize v. 归纳undercurrent n. 潜流theoretical adj. 理论上的potentiality n. 潜能intimate adj. 详尽的familiarity n. 熟悉的culpable adj. 应受遣责的Aristotelian n. 亚里士多德学派的人Aristotle n. 亚里士多德（公元前384-322，古希腊哲学家）Ptolemy n. 托勒密（公元90-168，古希腊天文学家）Leaning Tower of Pisa比萨斜塔spiral adj. 螺旋状的nebula n. 星云scratch n. 擦痕contrivance n. 器械distort v. 歪曲参考译文伽利略在世时是激烈论战的中心。

伽利略英语作文素材
伽利略英语作文素材Galileo Galilei was an Italian astronomer, physicist and engineer, sometimes described as a polymath. He has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science".Galileo's advancements in telescopic observational astronomy led to one of the most significant scientific revolutions in history. His improvements to the telescope and consequent astronomical observations resulted in his discovery of Jupiter's four largest moons in 1610. This was a significant event in the development of science, since a set of celestial bodies was discovered that did not appear to revolve around the Earth. The discovery of these moons is regarded by some as the first observation of a celestial motion uncentered on the Earth.Galileo is also credited with the formulation of inertia, the law of falling bodies, and parabolic trajectories. Moreover, he was the first to understand that the Moon did not shine with its own light but reflected the light of the Sun.In addition to his scientific discoveries, Galileo also made important contributions to the field of engineering. He improved the design of the compass and the balance, and developed a thermometer that used the expansion and contraction of air in a bulb to move water in a long thin tube.In conclusion, Galileo Galilei was an indomitable scientific figure who fearlessly pursued knowledge at a time when it was dangerous to do so. His discoveries and innovations in astronomy, physics, and engineering have had a lasting impact on the development of modern science andcontinue to inspire and influence scientists and researchers to this day.。

伽利略(GalileoGalilei,1564~1642)是伟大的意大利物理学
伽利略（Galileo Galilei，1564～1642）是伟大的意大利物理学家和天文学家，科学革命的先驱。
历史上他首先在科学实验的基础上融会贯通了数学、物理学和天文学三门知识，扩大、加深并改变了人类对物质运动和宇宙的认识。
为了证实和传播哥白尼的日心说，伽利略献出了毕生精力。
由此，他晚年受到教会迫害，并為终身监禁。
他以系统的实验和观察推翻了以亚里士多德为代表的、纯属思辨的传统的自然观，开创了以实验事实为根据并具有严密逻辑体系的近代科学。
因此，他被称为“近代科学之父”。
他的工作为牛顿的理论体系的建立奠定了基础。
伽利略1564年2月15日生于比萨，自幼受父亲的影响，对音乐、诗歌、绘画以及机械兴趣极浓，也像他父亲一样，不迷信权威。
17岁时遵从父命进比萨大学学医，可是对医学他感到枯燥无味，而在课外听世交、著名学者O·里奇讲欧几里得几何学和阿基米德静力学，感到浓厚兴趣。
1587年他带着关于固体重心计算法的论文到罗马大学求见著名数学家和历法家C·克拉维乌斯教授，大受称赞和鼓励。
克拉维乌斯回赠他罗马大学教授P·瓦拉的逻辑学讲义与自然哲学讲义，这对于他以后的工作大有帮助。
1588年他在佛罗伦萨研究院做了关于A·但丁《神曲》中炼狱图形构想的学术演讲，其文学与数学才华大受人们赞扬。
次年发表了关于几种固体重心计算法的论文，其中包括若干静力学新定理。
由于有这些成就，当年比萨大学便聘请他任教，讲授几何学与天文学。
第二年他发现了摆线。
1592年伽利略转到帕多瓦大学任教，他经常参加校内外各种学术文化活动，与具有各种思想观点的同事论辩。
此时他一面吸取前辈如N·F·塔尔塔利亚、G·B·贝内代蒂、F·科门迪诺等人的数学与力学研究成果，一面经常考察工厂、作坊、矿井和各项军用民用工程，广泛结交各行各业的技术员工，帮他们解决技术难题，从中吸取生产技术知识和各种新经验，并得到启发。

Then v t and d t 2. Therefore, d v2
But also, d h. So h v 2. Therefore, v h
Horizontal Component: continues with velocity v
Vertical Component: free fall from rest will take the same time t0 to reach the ground no matter what v is

R = v x t0 and therefore, R v Because v h , we finally get R
