Principia Mathematica

In 1687, Newton summarized his discoveries in terrestrial and celestial mechanics in his Philosophiae naturalis principia mathematica (Mathematical Principles of Natural Philosophy), one of the greatest milestones in the history of science. In this work he showed how his (45) principle of universal gravitation provided an explanation both of falling bodies on the earth and of the motions of planets, comets, and other bodies in the heavens. The first part of the Principia, devoted to dynamics, includes Newton s three laws of motion the second part to fluid motion and other topics and the third part to the system of the (50) world, in which, among other things, he provides an explanation of Kepler s laws of planetary motion.

Then, reading Bertrand Russel, I came to understand that this was not for me. I think I read just about everything that he wrote except for the Principia Mathematica., which I only dipped into. It s almost a life time s work to read those volumes.

One of the greatest members of the Royal Society was Isaac Newton. Newton was elected a Fellow of the Society in 1702 and became its president in 1703, a post he held until his death, in 1727. Newton had already established his power as a scientist with his work on physics and mathematics, demonstrated principally in his famous book Philosophiae naturalis principia mathematica, or, more commonly, the Principia. Like Boyle, Newton claimed to be following Baconian method and looked at the universe from a mechanical point of view. Unlike Boyle, Newton was much closer to Gassendi on the nature of matter. His analysis of physics was based in large part on the properties of matter, particularly the property of gravity, which he argued was inherent in anything that contained mass. For many years, Newton s ideas about physics were widely known, but Newton was also very interested in alchemy and believed in transmutation. In part because alchemy was discredited later, this part of Newton s scientific work was not often mentioned by historians, but it is now clear that his alchemical work influenced both his approach to science and his belief in certain properties of matter that were used in his physics.

Although some of the physical ideas of classical mechanics is older than written history, the basic mathematical concepts are based on Isaac Newton s axioms published in his book Philosophiae Naturalis Principia Mathematica or principia that appeared in 1687. Translating from the original Latin, the three axioms or the laws of motion can be approximately stated [7] (p. 13) ... 

Newton and the Spherical Earth. One of the first quantitative effective theories that I can think of is that associated with Newton and the invention of the integral calculus. In particular, the key question that had to be faced was whether or not it was possible to pretend as though the entire mass of the earth is concentrated at its center, rendering it for gravitational purposes, nothing more than a point mass. Newton s argument was schematized pictorially as in fig. 12.1 and asserted as Proposition LXXVI, Theorem XXXVI of the famed Principia Mathematica (Motte 1934).

Such was the case with Halley and Sir Isaac Newton. Halley apparently was still in his 20s when he first met Newton. The two became fast friends and encouraged each other s research. Halley seems to have been instrumental in encouraging Newton to complete his famous book, Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy). Better known simply as Principia, this book is one of the most important works of science ever written. In fact, Halley probably contributed financially to the cost of having the book published in 1687. In turn, Newton is thought to have been responsible for Halley s appointment as deputy controller of the Mint at Chester in 1696.

The subject of classical mechanics is the description of the motion of material bodies under the influence of given forces. All phenomena of classical nonrelativistic mechanics can be deduced from three basic axioms or laws of motion, which were first presented by Sir Isaac Newton in 1687 in his work Philosophiae Naturalis Principia Mathematica [39]. In modern language they can be formulated as ...

FIGURE 9.1 Sir Isaac Newton (1642-1727). In 1687, he published Principia Mathematica, in which his three laws of motion were first stated. They are still the most widespread way to describe the motion of objects. Knighted in 1705, Newton received this honor not for his scientific achievements, as is usually assumed, but for his political activities. 

His monograph Philosophice Naturalis Principia Mathematica (commonly known as Principia), published in 1687, laid the foundation for most of classical mechanics. In this work, Newton described the law of universal gravitation and the three laws of motion. The Principia is generally considered to be one of the most important scientific books ever written. 

Only a few years after Hooke expressed the concept that eventually led to the constitutive equation for the ideal elastic solid, Newton (Figure 2.1.1) wrote his famous Principia Mathematica. Here Newton expressed, among many other things, the basic idea for a viscous fluid. His resistance means local stress velocity by which the parts of the fluid are being separated means velocity...
