這是一部有關(guān)現(xiàn)代科學(xué)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(fēng)趣的筆法,將宇宙大爆炸到人類文明發(fā)展進(jìn)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(luò)。
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(xué)著模仿哦~~~??!
因?yàn)樵鵀槊绹怂鶎?單詞采用美式拼法,不抄全文,然后聽寫句子。請(qǐng)邊聽寫邊理解文意,根據(jù)上下文注意各句標(biāo)號(hào),這樣有助于提高正確率。
Hint:
Martin Rees
[---1---] each with different attributes, in different combinations, and that we simply live in one that combines things in the way that allows us to exist. He makes an analogy with a very large clothing store: “If there is a large stock of clothing, you're not surprised to find a suit that fits. [---2---] We are in that one.”
[---3---] For example, for the universe to exist as it does requires that hydrogen be converted to helium in a precise but comparatively stately manner—specifically, in a way that converts seven one-thousandths of its mass to energy. Lower that value very slightly—from 0.007 percent to 0.006 percent, say—and no transformation could take place: the universe would consist of hydrogen and nothing else. Raise the value very slightly—to 0.008 percent—and bonding would be so wildly prolific that the hydrogen would long since have been exhausted. [---4---]
Martin Rees, Britain's astronomer royal, believes that there are many universes, possibly an infinite number,
If there are many universes, each governed by a different set of numbers, there will be one where there is a particular set of numbers suitable to life.
Rees maintains that six numbers in particular govern our universe, and that if any of these values were changed even very slightly things could not be as they are.
In either case, with the slightest tweaking of the numbers the universe as we know and need it would not be here.
英國皇家天文學(xué)家馬丁?里斯認(rèn)為,有許多個(gè)宇宙,很可能是無數(shù)個(gè),每個(gè)都有不同的特性,不同的組合,我們只是生活在一個(gè)其組合的方式恰好適于我們存在的宇宙里。他以一家大服裝店作為例子來進(jìn)行類比:"要是服裝品種很多,你就不難挑到一件合身的衣服。要是有許多宇宙,而每個(gè)宇宙都由一套不同的數(shù)據(jù)控制,那么就會(huì)有一個(gè)宇宙,它的一套特定的數(shù)據(jù)適合于生命。我們恰好在這樣的一個(gè)宇宙里。"
里斯認(rèn)為,我們的宇宙受到6個(gè)數(shù)據(jù)的支配,要是哪個(gè)值發(fā)生哪怕是非常細(xì)微的變化,事物就不可能是現(xiàn)在的這個(gè)模樣。比如,現(xiàn)在的宇宙若要存在,就要求氫以準(zhǔn)確而較為穩(wěn)定的方式--說得具體一點(diǎn),要以將千分之七的質(zhì)量轉(zhuǎn)化為能量的方式--轉(zhuǎn)化為氦。要是那個(gè)值稍稍低一點(diǎn)--比如從千分之七降至千分之六--那么就不可能發(fā)生轉(zhuǎn)化:宇宙只會(huì)由氫組成。要是那個(gè)值稍稍高一點(diǎn)--高到千分之八--結(jié)合就會(huì)不間斷地發(fā)生,氫早已消耗殆盡。無論是哪種情況,只要這個(gè)數(shù)據(jù)稍有變動(dòng),我們所知的而又需要的宇宙就不會(huì)存在。
