*Principia Mathematica*(Mathematical Principles) is considered to be among the finest scientific works ever published. His grand unifying idea of gravitation, with effects extending throughout the solar system, explains by one principle such diverse phenomena as the tides, the precession of the equinoxes, and the irregularities of the moon's motion.Newton ...more

There are a lot of mathematical proofs scattered throughout the volumes, which were mostly less interesting to me than parts I could read as simply l ...more

It is shown in the Scholium of Prop. 22, Book II, that at the height of 200 miles above the earth the air is more rare than it is at the surface of the earth in the ratio of 30 to 0.0000000000003998, or as 75,000,000,000,000 to 1, nearly.

Marking this book as “read” is as much an act of surrender as an accomplishment. Newton’s reputation for difficulty is well-deserved; this is not a reader-friendly book. Even those with a strong background in science and mathematics will, I suspect, need some ...more

I finally learned why Newton is a genius. Why the planets stay in orbit. Why reason finally and forever took the place of authority. I learned when science was once and for all declared the way to "know". I learned why calculus is necessary and why Newton invented it. I learned why math is the language of the universe. I learned why geometry is so important.

I am in awe of Newton. Everything and everyone who followed him was influenced by him. Not just in the scien ...more

I tried. But this is Newton using geometry to explain the calculus behind his theory of gravity. Every few pages, between the charts and equations, he writes a one or two sentence introduction to the proposition about to be proved. I understood those. Mostly. And I could see this is where Newton’s Laws of Motions come from. His proofs are beyond me though.

Interestingly, one of the few other things I could understand, beyond his Preface, was the General Scholium at the end. After describing the h ...more

First, A Clarification: The publication I have is the hardcover revision by Florian Cajori of Andrew Motte's 1729 English translation, copyrighted in 1934 by the Regents of the University of California, and published by UC Berkeley and UCLA Press.

I should also note that, although I have read Newton's Principia several times over several years and for various reasons, I doubt I have ever completed the whole book. To do so would be advisable only under limited circumstances.

One can imagine an e-edition of this book where, as one reads the description of the ratio of this or that, the relevant lines on the diagram were highlighted. Even better, when areas are described by line segments belonging to the same line, the e-edition could add a side diagram with links to the ...more

- an ingenious and energetic builder who's astonishingly brilliant at composing gorgeous monuments of the most intensely clever design. Sometimes these appear as great books like the Principia itself. Sometimes they appear in experiments. But we would be wrong to look for a single key which unlocks the whole mystery of Isaac Newton.

总评：

当初想到读这本经典的缘起是什么呢？

是因为我读广义相对论的时候，意识到爱因斯坦所破的是很多传统观念的冗余，于是我尝试去读类似于《费恩曼物理学讲义》，然而却没有感觉，并且意识到——这种冗余已经很沉重，需要追根溯源，同时我还思考为什么物理学没有进行公理化，很多地方是漫漶不清的。于是开始阅读《自然哲学的数学原理》，追根溯源进行研究，并且我坚持认为运动学的本质应该是变分法，因此计划读完之后去读朗道的力学。同时发现，牛顿当初已经进行了公理化尝试，然而并没有归结到本质性问题（数学工具的不足）。在阅读到一半时，为了追求更本源，去读了亚里士多德的《物理学》，大失所望，才明白牛顿的正经祖宗并不是亚里士多德，而是阿基米德。

牛顿的写书意识逻辑是非常优美清晰的，比伽利略的作品要好很多了。然而其很多观点是建立在伽利略的观点基础上（如惯性的观念等），是伽利略观点的体系化、规范化。虽然都伽利略的书会少趣味，但还是看一看伽利略的力学观点《关于两门新科学的谈话》吧，动力学概念的源头，还是要寻找到伽利略头上 ...more

This book is epic. I once spilled glucosamine on it and my soul was ripped from my body by a jealous god.

One of the densest books that I've ever read, but also the most elegant and structured.
