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~~~?。?

In a single blinding pulse, a moment of glory much too swift and expansive for any form of words, the singularity assumes heavenly dimensions, space beyond conception. In the first lively second (a second that many cosmologists will devote careers to shaving into ever-finer wafers) is produced gravity and the other forces that govern physics. [---1---] There is a lot of heat now, 10 billion degrees of it, enough to begin the nuclear reactions that create the lighter elements—principally hydrogen and helium, with a dash (about one atom in a hundred million) of lithium. [---2---] We have a universe. It is a place of the most wondrous and gratifying possibility, and beautiful, too. [---3---]
When this moment happened is a matter of some debate. [---4---] The consensus seems to be heading for a figure of about 13.7 billion years, but these things are notoriously difficult to measure, as we shall see further on. All that can really be said is that at some indeterminate point in the very distant past, for reasons unknown, there came the moment known to science as t = 0. We were on our way.
In less than a minute the universe is a million billion miles across and growing fast.
In three minutes, 98% of all the matter there is or will ever be has been produced.
And it was all done in about the time it takes to make a sandwich.
Cosmologists have long argued over whether the moment of creation was 10 billion years ago or twice that or something in between.
剎那間,一個(gè)光輝的時(shí)刻來到了,其速度之快,范圍之廣,無法用言語來形容,奇點(diǎn)有了天地之大,有了無法想像的空間。這充滿活力的第一秒鐘(許多宇宙學(xué)家將花費(fèi)畢生的精力來將其分割成越來越小部分的1秒鐘)產(chǎn)生了引力和支配物理學(xué)的其他力。不到1分鐘,宇宙的直徑已經(jīng)有1600萬億公里,而且還在迅速擴(kuò)大。這時(shí)候產(chǎn)生了大量熱量,溫度高達(dá)1000萬攝氏度,足以引發(fā)核反應(yīng),其結(jié)果是創(chuàng)造出較輕的元素--主要是氫和氦,還有少量鋰(大約是1000萬個(gè)原子中有1個(gè)鋰原子)。3分鐘以后,98%的目前存在的或?qū)?huì)存在的物質(zhì)都產(chǎn)生了。我們有了一個(gè)宇宙。這是個(gè)美妙無比的地方,而且還很漂亮。這一切都是在大約做完一塊三明治的時(shí)間里形成的。
這個(gè)重大時(shí)刻的發(fā)生時(shí)間還是個(gè)有點(diǎn)爭(zhēng)議的問題。宇宙到底是在100億年以前形成的,還是在200億年以前形成的,還是在100億年到200億年之間形成的,這個(gè)問題宇宙學(xué)家已經(jīng)爭(zhēng)論很長時(shí)間。大家似乎越來越贊成大約137億年這個(gè)數(shù)字。但是,我們?cè)诤竺鎸?huì)進(jìn)一步看到,這種事情是極難計(jì)算的。其實(shí),我們只能說,在那十分遙遠(yuǎn)的過去,在某個(gè)無法確定的時(shí)刻,由于不知道的原因,科學(xué)上稱之為t=0的時(shí)刻來到了。我們于是踏上了旅程。
