European Science in the Age of Galileo 伽利略時代的歐洲科學 撰文及考題設計 British Council 英協教育中心 Brian Welter 中譯 陳怡君 （中央社編譯）
1
Italian scientist Galileo Galilei (1564-1642) was as famous for his struggles with the authorities of his day as for his scientific discoveries, which included the nature of the physical universe. An able inventor, he also significantly improved the telescope and used it to prove his theories about astronomy. He faced controversy in part because science was undergoing profound upheaval. 義大利科學家伽利略（1564-1642）與當代政府 的對抗，和他的科學發現─包括對於物理宇宙本 質的研究同樣聞名。伽利略是個了不起的發明家， 他大幅加強望遠鏡的功能，並用此證明他的天文 學理論。然而伽利略受到廣泛質疑的部分原因在 於，當年的科學正處於深刻動盪的狀態。

Thus when Galileo saw through one of his telescopes that the moon’s surface was not shiny and smooth as Aristotle said it was, but rocky and full of peaks and valleys just like on Earth, many people disbelieved him. His supporters in Rome or Florence would hold gatherings with him as the guest of honour so that he could show the skeptics the moon through his telescope. Both he and his telescope were the wonders of the time. Because night conditions were not always favourable to viewing the moon’s surface, many people still continued to follow the old ways, unconvinced of the fresh insights
