Principia: Vol. II: The System of the World

by Isaac Newton

I consider philosophy rather than arts and write not concerning manual but natural powers, and consider chiefly those things which relate to gravity, levity, elastic force, the resistance of fluids, and the like forces, whether attractive or impulsive; and therefore I offer this work as the mathematical principles of philosophy.In the third book I give an example of this in the explication of the System of the World. I derive from celestial phenomena the forces of gravity with which bodies tend to the sun and other planets.

About the author

Sir Isaac Newton, FRS , was an English physicist, mathematician, astronomer, natural philosopher, and alchemist. His Philosophiæ Naturalis Principia Mathematica, published in 1687, is considered to be the most influential book in the history of science. In this work, Newton described universal gravitation and the three laws of motion, laying the groundwork for classical mechanics, which dominated the scientific view of the physical universe for the next three centuries and is the basis for modern engineering. Newton showed that the motions of objects on Earth and of celestial bodies are governed by the same set of natural laws by demonstrating the consistency between Kepler's laws of planetary motion and his theory of gravitation, thus removing the last doubts about heliocentrism and advancing the scientific revolution.

In mechanics, Newton enunciated the principles of conservation of momentum and angular momentum. In optics, he invented the reflecting telescope and developed a theory of colour based on the observation that a prism decomposes white light into a visible spectrum. He also formulated an empirical law of cooling and studied the speed of sound.

In mathematics, Newton shares the credit with Gottfried Leibniz for the development of the differential and integral calculus. He also demonstrated the generalised binomial theorem, developed the so-called "Newton's method" for approximating the zeroes of a function, and contributed to the study of power series.

Newton was also highly religious (though unorthodox), producing more work on Biblical hermeneutics than the natural science he is remembered for today.

In a 2005 poll of the Royal Society asking who had the greater effect on the history of science, Newton was deemed much more influential than Albert Einstein.

Eu não vou dar avaliação.
Existe um motivo para isso: como posso dar avaliação de um livro que eu não sei avaliar?
Eu sou apreciadora de astronomia e astrofísica, mas infelizmente não passo de uma amadora: falta-me o saber científico.
Neil deGrasse Tyson recomendou este como um dos livros indispensáveis a quem se interessa por astronomia, mas eu nunca fui boa aluna a matemática e nunca tive a oportunidade de estudar física, então para mim isto era uma linguagem ininteligível e confusa.
Eu percebi algumas coisas, como o fato de ele calcular não só as órbitas dos planetas e satélites como as órbitas de outros corpos celestes (meteoritos e meteoros). No entanto, é tudo demasiado técnico e eu não tenho essa experiência.
De qualquer forma, reconheço que foi um livro imprescindível a outros cientistas depois de Newton, que ajudou no desenvolvimento do telescópio, entre outros cálculos que ajudaram à descoberta das ondas fora do espectro vísivel e, consequentemente, a invenção de satélites espaciais, entre outras invenções.

I read this for Neil deGrasse Tyson's list of eight books every intelligent person should read. I don't feel like I can give it a rating because I didn't follow any of the math, but I did enjoy Newton's arrogance. It was amazing how much people could learn in the 1600s with the limited technology and religious influences that surrounded scientists.

e book review: A challenging science book but a rewarding reading experience to appreciate the powers of observation and mathematics. A discussion of the scientific proofs on the motion of the planets by Newton.

Mind blown. Almost accurate description of the solar system dynamics - almost 300 years ago! - plus the beginning of modern calculus. A bit too many OCR errors for the Kindle edition, but nothing that you can't figure out from the context.

Fascinating and humbling.

It's great to see how some human-beings can transmit thoughts firstly seen as too hard with such an ease.

Neil says to read this book: "to learn of our kinship with all other life on earth"

Título póstumo del gran físico inglés, realizado con sus cuadernos, anotaciones, cartas y demás apuntes. El libro resulta un poco desordenado y de una lectura a veces tediosa, o eso me ha parecido. Cita en numerosas ocasiones teoremas de los Principia, sus leyes fundamentales de la física o la ley de la Gravitación Universal, así como conversaciones con otros gandes de la época como Kepler y Tycho Brahe. Me llama la atención como con tan pocos medios eran capaces de conocer con tanta precisión las órbitas de los planetas y demás cuerpos del sistema solar, aunque el auténtico mérito se encuentra en que precisamente eran físicos teóricos y estaban dando los pasos en la dirección correcta.

This is difficult read that reminds me of the days of plowing my way through Calculus. Although painful, it's a humbling experience to realize my limited intelligence and desire to be this focused on a subject. I accept the moon is out there at a given distance and travel at an arc around the earth. In addition, I appreciate the brilliance of the people that made these discovers. But, I do not want to read the details.

In addition, I do not want to read the never ending detail about water tides. I did however have an ah ha moment when water rises in one place it must recede someplace else. Dah ....

Well, bottom line, it's not an exciting book.

5 stars to Newton's obvious contribution to science but tbh I didn't understand 99% of what I read.

[Trounin · Rating 3 out of 5]

Чтобы понять, почему предположения Ньютона следует считать истинными, нужно ознакомиться с приводимыми им правилами для умозаключений в физике. Исходить приходится из понимания достижений науки на определённый момент времени. Более имеющегося Ньютон брать не предлагает. Нельзя уходить в измышлениях в доселе скрытые материи. Всё требуется объяснять посредством проведённых опытов. Ньютон провёл оные, о чём написаны первая и вторая книги, подготовив доказательства для обоснования собственной системы мира.

Before reading this, take a look at my review of "Dark Horse", a good story by Diener or Powers of the Earth (a bad story) and its comments. If you couldn't be bothered, please don't bother with my reviews.

GLORY TO UKRAINE !!!!

I was curious about the book and it was reasonably priced and It's Isaac Newton. I was more curious about what the language would be like. Knowing the basics of gravitational attraction and the impact of speed of an object and size of the attractor on an orbital path is everyday knowledge thanks to him.

To see orbital mechanics explained using only logic, geometry and millennia of observation was kind of mind blowing. He writes it so matter of factly and in the late 17th century. It only took materials science, engineering and propulsion advancement about 250 years to catch up.

It's a short piece and it probably only matters if you're in the mood to nerd out. If so, you might like reading this.

Curiosity Stream/Nebula gives me a good selection of educational video and at $15 USD for a year's subscription, it's worth a look.

For a real community of readers, I suggest YouTube. I found channels on my other interests as well. Some favorites are.

Si Dios hubiese puesto al principio un cierto grado de movimiento en las cosas y después este movimiento solo se distribuyese por choque parece que iría decreciendo continuamente en su movimiento por el efecto de los choques contrarios sin ser capaz de recuperarlo nunca y que el universo caería muy pronto en tal estado de reposo que ello supondría la muerte del todo. La fuerza de Atracción que siempre subsiste y no se ve debilitada por su ejercicio es una fuente perpetua de acción y de vida. Puede suceder igualmente que los efectos de esta fuerza

A short but incredibly difficult book to read. I have an interest in space, astronomy and science but this book delves quite deep into the working of the solar system. My difficulties came from the language used (obviously I am aware it was written sometime ago). Not recommended for anyone but the most dedicated science historians for you can get all this information in much clearer (and up to date) way for any number of current books

This will be short and sweet, because I really don’t have much to say about this book. I picked it up from historical curiosity more than anything else. Honestly thought it was going to be a lot more math heavy and I was pretty intimidated. While there are a few bits and pieces that were technical, I mostly found his writing to be straightforward. It’s a pretty quick read, so certainly worth it for anyone who is curious.

The first bit was interesting where he describes his famous laws of motion. After that it is a challenging series of proofs.

Can anyone please give some review? I really really interested in science and this book, but is it worth my money?

I may have understood more going in with a basic understanding of calculus, but still interesting reading about the forces working upon the planets, moons, tides, etc.
