AI导读
核心看点
- 伽利略创立近代科学基石，涵盖力学与天文学。
- 以对话体呈现，融合几何论证与思想实验。
- 探讨无限集合、自由落体及抛体运动规律。
适合谁读
- 对科学史、物理学起源及经典文献感兴趣的读者。
- 具备一定数学基础，喜欢逻辑推演的理工科学生。
- 希望了解伽利略科学方法与思维方式的爱好者。
读前提醒
- 采用对话体，人物仅为辩论工具，无情节铺垫。
- 大量使用几何证明，阅读需耐心，建议结合导读。
- 内容深奥且冗长，建议重点阅读核心命题部分。
读者共识
- 科学史上的里程碑，伽利略最伟大的贡献所在。
- 论证新颖严谨，虽部分观点受时代局限仍具价值。
- 阅读门槛较高，适合静心研读，非通俗科普读物。

- ""The attributes of greater, lesser, and equal to do not suit infinite, of which it cannot be said that one is greater, or less than, or equal to, another." ..."only in bounded quantities"..."it may not even be said to be greater than another infinite, but it may not even be said that an infinite is "
- ""It must be said that square numbers are as numerous as all numbers,because they are as many as their roots, and all numbers are roots.""
- ""Whether the quantified parts of the continuum are finite, or infinitely many?"..."Neither finite nor infinite." "If any number may be called infinite, it is unity.""
- "The time in which a certain space is traveled by a moveable in uniformly accelerated movement from rest is equal to the time in which the same space would be traversed by the same moveable carried in uniform motion whose degree of speed is one-half the maximum and final degree of speed of the previo"
- ""If two moveable are carried in equable motion but at unequal speeds. the spaces run through by them in unequal times have the ratio compounded from the ratio of speeds and from the ratio of times.""
- "The line described by a heavy moveable, when it descends with a motion compounded from equable horizontal and natural falling motion, is a semi-parabola."
- "#274"It cannot be denied that the reasoning is novel, ingenious, and conclusive, being argued ex suppositione; that is, by assuming that the transverse motion is kept always equable, and that the natural downward motion likewise maintains its tenor of always accelerating according to the squared rat"
- "#65 "And the author of nature has been able to practice this divine and infinitely marvellous art, because each portion of matter is not only divisible to infinity, as the ancients have recognised, but is also actually subdivided without end, each part divided into parts having some motion of their "
用户评论
本书主要运用了几何方法，因此更适合数学爱好者。从科学的角度来说，《对谈》比《对话》更加重要。伽利略对落体运动、抛体运动、材料力学和声学的阐述都是革命性的，就算他既不知道重力的来源而坚持圆周运动的自然属性，也不认识悬链线。
老公给我买的，可惜无法读进去正文，只读了导读，感觉伽利略是一个心智比较正常，命运并无太大坎坷的难得的科学家…鱼洗好神奇哦。
科学用文学表达，运动开启牛顿和爱因斯坦

读起来有点古怪。引入了两个人物，以对话的方式展开，但又没有任何人物背景介绍和相关情节。人物仅仅是道具，通过质疑、辩论来阐述作者的思想。有点像是左右手打架，真正的高手都是孤独的。写的有点冗长，缺乏主题。但在那个时代，书中提到的几个方面几乎都是开创性的新思想或总结
伽利略对近代科学最伟大的贡献全部体现在这部书中！
