- Reading I like reading very much.When I was a pupil,I interested in historical books,such as Five Thousand Years Of Chinese and Five Thousand Years Down The World.It seemed to travel in remote time and space to look their life and culture.Then in the middle school,I started read chinese classical novels such as the four famous chinese classics.Their beauty languages attracted me to love literature and wanted to become a writer.Up to now,I don't give up writing.And from high school,I read materials on foreign literature,Jane Eyre,Pride and Prejudice,Wuthering Heights and so on.Above all,my favorite book is Gone With The Wind,which was read in my university days.Because I appreciate the courage of Scarlett and Reiter's infatuation for love.Especially"Tomorrow,tomorrow is another day."I still remember it,which encourage me yet.So books are my best friends!May 7, 201020
我信仰科技 II
虽然我们无法计算出宇宙中恒星的正确数量,据估计约有1,000,000,000,000,000,000个或10亿亿个。接下来我们假定每个恒星有5个行星在环绕。据我们所知,宇宙当中唯一有智能生命的行星就是我们地球,因此,创造生命的概率是1/5,000,000,000,000,000,000。
现在让我们看看地球上的生命:<strike>。</strike><strike>现在,</strike>大约有140万不同的物种,还不包括那些已经灭绝或我们尚未<strike>还没有</strike>发现的。我认为这个数字可以提高到200万(虽然我个人认为1千400万会更加接近事实),因此人类能够在地球上被创造出来的概率是1 /2,000,000。
现在需要看我们在地球上进化到这个阶段的概率。这个有着一定的难度。因为有很多因素影响我们多年的演变,因此我认为要计算出来是几<strike>近</strike>乎不可能的。为了这篇文章,我将会假定1/10亿 (我其实跟上面一样想写在1 / 1,000,000,000,000,000,000左右)。但我故意将其低估。
现在我们进入更深入的说明-我们要算历史上所有的随机事件,从战争到饥荒、自然灾害的影响到政府,从你的母亲遇到你父亲到你周围的朋友和你老师这些历史上所有的随机事件,导致你现在阅读这篇我写的文章。我能在这里的概率跟你一样。但是我们能够在世界上数以亿计的人当中互动的可能性…这也许是最难去估算的概率。
让我们将它们结合在一起来算一下:
宇宙被创造时拥有了精确的物理常数 + 一个能够维持生命的行星 + 人类创造 + 人类进化+ 你和我的存在 + 我有这些想法并写这篇文章 + 你在线看这篇文章 + …
加上无数个零!
我要是说答案是1×10 ^ 1千(小数点后1000零) 我认为这是很保守的数字。
这些信息该怎么理解呢?一位嬉皮会告诉你是说明你能够在这里生活很不容易,很幸运,因此你要好好享受!但作为一名科学家,我会说:
这意味着任何在我们宇宙当中发生的概率大于1 / 1×10 ^ 1000不能被视为不重要而忽视。我们如此的渺小,寿命如此的<strike>这么</strike>短,而我们对宇宙的了解如此<strike>这么</strike>有限,说不定,我们认为很罕见的事件,对宇宙来说却已<strike>经</strike>成为了普遍现象。
爱你的家人,善待并尊重他人,尽可能地多去学习并且保持心胸开阔。最后一点,别怕有遗憾-再次轮回重获机会的概率远比你现在拥有的少得多 - 把握当下!0 votedMay 7, 20100- Tension I started new job three days.Because the lady before me didn't hand over work, I could do nothing.Every day I look over her notes.I find she is a strict and conscientious girl.In fact, I think I'm proud of my professional competence.However,yesterday I found her work report in English,I felt a tension around me.How can I do better than her? I can't give up!I will continue to learn and make great efforts.May 6, 201020
