原來伽利略的天文望遠鏡已經發明400年了...

南西找遍了幾個網站, 很多都只有概略敘述一下1609年使用望遠鏡的! 但是都沒指到哪一天... 找了好久, 終於在這裡找到...

Based only on uncertain descriptions of the first practical telescope, invented by Hans Lippershey in the Netherlands in 1608, Galileo, in the following year, made a telescope with about 3x magnification. He later made others with up to about 30x magnification. With this improved device he could see magnified, upright images on the earth – it was what is now known as a terrestrial telescope, or spyglass. He could also use it to observe the sky; for a time he was one of those who could construct telescopes good enough for that purpose. On 25 August 1609, he demonstrated his first telescope to Venetian lawmakers. His telescopes were a profitable sideline. He could sell them to merchants who found them useful both at sea and as items of trade. He published his initial telescopic astronomical observations in March 1610 in a brief treatise entitled Sidereus Nuncius (Starry Messenger).

還是要看英文的wiki資料才詳細啊! 南西看了中文版還找一堆網站, 都沒看到到底哪天使用望遠鏡, 終於在英文版被我看到啦!!

當然, 伽利略不只發明了這個歐, 他還發明了溫度計等等! 大家也可看看中文的wiki, 寫的也挺詳細的!

以上!
