這是一部有關現(xiàn)代科學發(fā)展史的既通俗易懂又引人入勝的書,作者用清晰明了、幽默風趣的筆法,將宇宙大爆炸到人類文明發(fā)展進程中所發(fā)生的繁多妙趣橫生的故事一一收入筆下。驚奇和感嘆組成了本書,歷歷在目的天下萬物組成了本書,益于人們了解大千世界的無窮奧妙,掌握萬事萬物的發(fā)展脈絡。
收獲英語 收獲一本好書~!
書本的朗讀語音很charming的磁性英音~~~大家可以好好學著模仿哦~~~??!
因為原著為美國人所寫,單詞采用美式拼法,不抄全文,然后聽寫句子。請邊聽寫邊理解文意,根據(jù)上下文注意各句標號,這樣有助于提高正確率。
[---1---] Not long after, mind you. By doing a lot of math and watching carefully what goes on in particle accelerators, scientists believe they can look back to 10^-43 seconds after the moment of creation, when the universe was still so small that you would have needed a microscope to find it. [---2---] Thus 10^-43 is 0.0000000000000000000000000000000000000000001, or one 10 million trillion trillion trillionths of a second.
Most of what we know, or believe we know, about the early moments of the universe is thanks to an idea called inflation theory first propounded in 1979 by a junior particle physicist, then at Stanford, now at MIT, named Alan Guth. [---3---] He would probably never have had his great theory except that he happened to attend a lecture on the Big Bang given by none other than Robert Dicke. [---4---]
The Big Bang theory isn't about the bang itself but about what happened after the bang.
We mustn't swoon over every extraordinary number that comes before us, but it is perhaps worth latching on to one from time to time just to be reminded of their ungraspable and amazing breadth.
He was 32 years old and, by his own admission, had never done anything much before.
The lecture inspired Guth to take an interest in cosmology, and in particular in the birth of the universe.
大爆炸理論并不是關于爆炸本身,而是關于爆炸以后發(fā)生的事。注意,是爆炸以后不久。科學家們做了大量計算,仔細觀察粒子加速器里的情況,然后認為,他們可以回顧爆炸發(fā)生10^-43秒之后的情況,當時宇宙仍然很小,要用顯微鏡才看得見。對于每個出現(xiàn)在我們面前的非同尋常的數(shù)字,我們無須把自己搞得頭昏腦漲,但有時候也許不妨理解一個,只是為了不忘其難以掌握、令人驚奇的程度。于是,10^-43秒就是0.000 000 000 000 000 000 000 000 000 000 000 000 000 000 1秒,或者是一千億億億億分之一秒。
我們知道的或認為知道的有關宇宙初期的大部分情況,都要歸功于一位年輕的粒子物理學家于1979年首先提出的膨脹理論。他的名字叫艾倫?古思,他當時在斯坦福大學工作,現(xiàn)在任職于麻省理工學院。他當時32歲,自己承認以前從沒有作出過很大的成績。要是他沒有恰好去聽那個關于大爆炸的講座的話,很可能永遠也提不出那個偉大的理論。開那個講座的不是別人,正是羅伯特?迪克。講座使古思對宇宙學,尤其是對宇宙的形成產生了興趣。
