自然发生学说
伊金
编者按
好辩的化学家詹姆斯·阿尔弗雷德·万克林曾在《自然》上发表文章提出,鉴于空气中含氮物质的含量很低,是否真的可能存在那么多被认为足以导致疾病的看不见的细菌?而他更倾向于自然发生说,即生命体可以从纯无机物中生成。一位读者读了万克林的快报文章后提出,万克林的计算实际上是对疾病的细菌学说的支持而不是反对。在这篇文章中查尔斯·伊金表示对还有人在争论以上两种理论感到吃惊,因为路易·巴斯德早在近十年前就已经提出了这些观点。尽管有越来越多的证据支持了疾病的细菌学说,但有些... | 400套付费套装书 |

金星从日面划过而发生的凌日现象比其他任何天文现象都更能引起人们的关注,天文界投入了巨大的精力去研究这一现象。在上个世纪,研究凌日现象是精确获得日地距离的唯一方法,凌日现象的这种重要性使得人们对它的出现相当期待。尽管现在也有其他的方法能以同样的精度确定日地距离,但金星凌日这种天象的罕见性使它受到了比其他观测更多的关注。和观测金星凌日一样,对火星的某些特殊观测同样需要天文学家们的集体协作,而确保这次协作的能力为观测金星凌日提供了在火星的观测中不曾拥有的优势。 英文

在法国南部,丝绸的生产作为工业体系的一个重要分支已经有几个世纪了。1853年,法国该产业的年产量已经达到了占据整个世界该产业年产量的1/10的程度,这代表着117,000,000法郎的货币价值,或者说将近500万英镑的货币价值。所有产业中与生丝的生产相关的行业创造的货币价值的总额,我想比我能够估计出来的还要多得多。可以这么说,里昂是靠法国的蚕丝建立起来的,就像内战前的曼彻斯特是靠美国的棉花建立起来的一样。 英文

流星自西向东运动的事实是非常重要的。如果坠落到太阳上的流星是持续不断而且坠落密度差不多是均匀的话,那么几乎不用怀疑:流星肯定会像整个太阳系一样围绕着太阳自西向东运动,从空间上来说它们应该是非常扁圆的球体,而且其赤道面应该几乎和太阳的赤道面相重合。 英文
如果事实的确如此,那么大量的流星就会坠落到太阳的赤道附近而不是两极,从而使太阳的赤道比两极更热。实际上,事实正是如此。在没有任何理论支撑的情况下,塞奇已经通过实验确认了太阳的赤道明显比两极热。实验中使用了电热倍增器,该仪器显示的结果是来自太阳赤道和两极这两个热源的热量差值,而不是其比率。 英文
