改變世界的發明

What will our lives look like without telephones, computers and airplanes? 

So many inventions have changed the world. It will be much more difficult to spread ideas without the skill of printing. Before telegraph is invented, some people built up moving arms at the top of top building as a way of signaling. Do you know that Pythagoras probably learnt about right-angled triangles from the Babylonians?

“Inventions that changed the world” (F MAU) tells stories of different inventions. It is on the S.4 booklist of another Tuen Mun school. You can borrow it after the Lunar New Year holiday.

沒有了電話、電腦、飛機，我們的生活會是怎樣的？

很多發明改變了世界的面貌。沒有印刷術，傳播訊息將會難度加倍；電報發明前，有人在高樓上建造可轉動的木臂來傳達訊號；你知道畢達哥拉斯可能是從巴比侖人學會直角三角形知識嗎？

“Inventions that changed the world” (F MAU) 述說不同發明的故事，本書是屯門友校中四指定reader，農曆新年過後你可在圖書館借閱。
