Newton's Principia for the Common Reader

Representing a decade's work from one of the world's most distinguished physicists, this major publication is, as far as is known, the first comprehensive analysis of Newton's Principia without recourse to secondary sources. Chandrasekhar analyses some 150 propositions which form a direct chain leading to Newton's formulation of his universal law of gravitation. In each case, Newton's proofs are arranged in a linear sequence of equations and arguments, avoiding the need to unravel the necessarily convoluted style of Newton's connected prose. In almost every case, a modern version of the proofs is given to bring into sharp focus the beauty, clarity, and breathtaking economy of Newton's methods. This book will stimulate great interest and debate among the scientific community, illuminating the brilliance of Newton's work under the steady gaze of Chandrasekhar's rare perception.



Summary: On Newton's Quiet Endorsement of Euclid's Brilliance: Chandra's Greatness!
Rating: 5

This work, although beyond my competence in mathematics, is designed for "the common reader." With just--a desideratum I lack--calculus and geometry, Chandra demonstrates certain fundamental scholia of Newton's treatise. But he does more than this. He shows us what Descartes suspected--that the classical geometers and Newton, in a way, new the same things. Descartes was the first to voice his "suspicion" that the classical mathematicians knew the methods of modern, calculus-based numerical analysis, but did not reveal such (Descartes' foundational act, his creation of "analytical geometry," is the point of "closest contact" ( Leo Strauss in a different comparison: Xenophon and Machiavelli) between ancient mathematical science and modern. By casting "Principia" in classical geometry, Newton--in a tradition profoundly indebted to Descartes and, therefore, Spinoza, shows his assent to Descartes' premise. If Newton's "Principia" can be elaborated by Euclid's methods, then, perhaps, Euclid is not so Parmenidean after all. In other words, there is a kinematicism (Parmenides) and a dynamism (Heraclitus)--i.e., Einstein and quantum theory--within classical mathematical science.
I find this in Euclid's ambiguous definition of "point" within his "elements" and within his non-theorem, but postulate, the famous "fifth"--which scholars have labored in vein to derive from his other four axioms.
They have now discovered that it cannot be done, which is why it is a "postulate," rather than an "axiom."
Newton, to say nothing of Euclid, chose all words carefully: Chandra brings this to light for us. This should not cause us to shrug our shoulders and say, "Well, then, it has all been done before, why do anything in science?" It should, rather, challenge us to say, "How can I prove that?"
Maybe you cannot, and I know I cannot: So it has the effect of conserving for us the greatness of our tradition, while asking us to go beyond it by not allowing us the, "We stand on the shoulders of the shoulders of giants, so we see farther than they" platitude. Therefore, above all, the mystery of Newton's cosmology is revealed to us. We have found our way out of the Labyrinth of millenial confusion only to recover the greatness of Our Tradition: Our gratitude to Chandra is infinite! So, perhaps, is the cosmos in which it emerged.

Summary: i'm ordering this book having looked through it
Rating: 5

perhaps the title "...for the common reader" is the issue here. "the common reader familiar with calculus", perhaps...

there's simply no way anyone without a very solid grounding in mathematics can read this book and understand it. we are talking about the laws of motion & gravity here, etc.

i compared this (a bit dogeared) copy of a book sided by side with a modern copy of principa in a bookshop, and for anyone wishing to tackle this monumentally important work, i cannot think of a better pairing. a modern copy of newton's principia and chandrasekhar's great work for those who wish to see a thorough explanation and working of the equations.

it's like a lot of things; be realistic with your expectations.
someone who is not very competent in mathematics is not going to be able to ever fully comprehend the contents of this book, misleading title notwithstanding.

perhaps the person that gave this book one star would like to let us know what scientific books he has awarded five stars to if he thinks so lowly of this one?

i say all this, because i'm currently self-studying algebra to be able to self-study calculus next year, just so i can try and understand some of this all-important book.

so don't knock the book, just keep putting the time in & struggling (and it's a struggle, alright) with the mathematics that unlock its secrets.

This book was written by the Indian-American Nobel Laureate who has a physical stellar size limit to his name. Chandra (the author of this book, who also has an orbiting X-ray telescope named after him..some guys have all the luck), who was amongst the most meticulous of theorists and who worked with bigwigs like Eddington, Russell, Dirac, Bethe, Fermi and Von Neumann amongst the most luminous, wrote this massive (and his last) work of Newton's Principia. This is Chandra's take on Newton's work. Don't think its a light read - It isn't.

You cannot take it with you to starbucks (its big and heavy) sip cappucino and browse the work. You'll need to be at a table with a straight-back chair and concentrate intensely. If you know Chandra's work, then you will know that chandra always said just about what was required and said it in great English (possibly influenced by Eddington's writing) and his work is un-apologetically mathematical. So essentially this is a 20th century giant interpreting the work of THE giant of all time. It is NOT a verbatim reproduction in English of the original latin publication of the Principia. It is expensive for a reason. Its beautifully written and bound very beautifully in a red jacket with Newton's bust and handwriting on the jacket. If you bought it, the red cover is attractive enough to make it stand out of your living room book shelf. Most importantly, Chandra tackles each aspect of Newton's principia in a his own manner. GET IT if you can afford it and if you can't, try a used book place. But get it anyway.
