穿越銀河。傅湘雯譯。
這種圖多字少的「科學類童書」頗適合我。真可謂有志不在年高。哈哈!
這套啟思文化翻譯引進的《最新天文科學全集》共有七本,分別是:《穿越銀河》、《捕捉流星》、《登陸月球》、《星星真相》、《觀測星座》、《神秘彗星》、《行星之旅》。特色是卡通插圖與太空照片合成,蠻不錯。雖然每本書只有短短四十頁,但貪多嚼不爛,篇幅少正適合反覆翻看,少勝於多。而且有時最基礎的,正是成年人最缺乏的。
本書有兩個地方最有價值。一是刊出幾種不同形狀星系的照片:如漩渦星系、橢圓星系、棒旋星系、寬帽星系、「戒環星系」(此為本人命名)、不規則星系等。銀河系屬於漩渦星系。
二是用風車來形容銀河系。太陽系在某一個風車葉片上,距銀河中心有三萬光年遠。銀河系直徑則是十萬光年。
就算只有四十頁,也有很多問題可以思考。例如:如果太陽系正隨著漩渦葉片一起轉動,為什麼我們不會覺得暈頭轉向呢?作者回答是因為太陽系和銀河太大又太遠之故。大概是吧!不過他又叫我們假設自己是一隻困在汽車裡的蒼蠅,當這輛車子已經開出幾十公里後,蒼蠅可能還不知道自己一直在移動。但這個蒼蠅的例子應該是表示「慣性定律」,不是嗎?還是兩者都有呢?
