OpticksA treatise of the reflections, refractions, inflections and colours of light. E-book. Formato EPUB Sir Isaac Newton - Balungi Francis, 2024 -
Part of the ensuing Discourse about Light was written at the Desire of some Gentlemen of the Royal-Society, in the Year 1675, and then sent to their Secretary, and read at their Meetings, and the rest was added about twelve Years after to complete the Theory; except the third Book, and the last Proposition of the Second, which were since put together out of scatter'd Papers. To avoid being engaged in Disputes about these Matters, I have hitherto delayed the printing, and should still have delayed it, had not the Importunity of Friends prevailed upon me. If any other Papers writ on this Subject are got out of my Hands they are imperfect, and were perhaps written before I had tried all the Experiments here set down, and fully satisfied my self about the Laws of Refractions and Composition of Colours. I have here publish'd what I think proper to come abroad, wishing that it may not be translated into another Language without my Consent.The Crowns of Colours, which sometimes appear about the Sun and Moon, I have endeavoured to give an Account of; but for want of sufficient Observations leave that Matter to be farther examined. The Subject of the Third Book I have also left imperfect, not having tried all the Experiments which I intended when I was about these Matters, nor repeated some of those which I did try, until I had satisfied my self about all their Circumstances. To communicate what I have tried, and leave the rest to others for farther Enquiry, is all my Design in publishing these Papers.In a Letter written to Mr. Leibnitz in the year 1679, and published by Dr. Wallis, I mention'd a Method by which I had found some general Theorems about squaring Curvilinear Figures, or comparing them with the Conic Sections, or other the simplest Figures with which they may be compared. And some Years ago I lent out a Manuscript containing such Theorems, and having since met with some Things copied out of it, I have on this Occasion made it publick, prefixing to it an Introduction, and subjoining a Scholium concerning that Method. And I have joined with it another small Tract concerning the Curvilinear Figures of the Second Kind, which was also written many Years ago, and made known to some Friends, who have solicited the making it publick.In this Second Edition of these Opticks I have omitted the Mathematical Tracts publish'd at the End of the former Edition, as not belonging to the Subject. And at the End of the Third Book I have added some Questions. And to shew that I do not take Gravity for an essential Property of Bodies, I have added one Question concerning its Cause, chusing to propose it by way of a Question, because I am not yet satisfied about it for want of Experiments.This new Edition of Sir Isaac Newton's Opticks is carefully printed from the Third Edition, as it was corrected by the Author's own Hand, and left before his Death with the Bookseller. Since Sir Isaac's Lectiones Opticæ, which he publickly read in the University of Cambridge in the Years 1669, 1670, and 1671, are lately printed, it has been thought proper to make at the bottom of the Pages several Citations from thence, where may be found the Demonstrations, which the Author omitted in these Opticks.
Observations upon the Prophecies of Daniel and the Apocalypse of St John ( Annotated and Translated Edition)Occult studies and religious tracts dealing with the literal interpretation of the Bible. E-book. Formato EPUB Sir Isaac Newton - Balungi Francis, 2021 -
Sir Isaac Newton (1643-1727) was, of course, an English physicist, mathematician, whose Principia (published in 1687) founded classical mechanics, and described universal gravitation and the three laws of motion; his other major work is the Opticks . He was also, however, a fervent believer in God, and devoted considerable time in his later years to studying the Bible and biblical prophecy.Isaac Newton was considered an insightful and erudite theologian by his contemporaries. He wrote many works that would now be classified as occult studies and religious tracts dealing with the literal interpretation of the Bible.Newton's conception of the physical world provided a stable model of the natural world that would reinforce stability and harmony in the civic world. Newton saw a monotheistic God as the masterful creator whose existence could not be denied in the face of the grandeur of all creation. Although born into an Anglican family, by his thirties Newton held a Christian faith that, had it been made public, would not have been considered orthodox by mainstream Christians; Scholars now consider him an Arian. John Rogers in 2019 stated, "Heretics both, John Milton and Isaac Newton were, as most scholars now agree, Arians."Anyone who's interested in Biblical prophecy should want to know Newton's thoughts on the subject.
Newton's PrincipiaThe Mathematical Principles of Natural Philosophy by Sir Isaac Newton. E-book. Formato EPUB Sir Isaac Newton - Balungi Francis, 2020 -
It was Isaac Newton's Principia that founded the law of universal gravitation on 5th July 1687. It is the same principia that inspired Albert Einstein into formulating the Einstein field equations (the general relativity theory). It is still the same principia, I believe, will lead us to the quantum theory of gravity (Quantum gravity)According to Newton’s Principia, the force of gravity governs the movement of bodies in the solar system. It is this simple mathematical law which determines the motion of bodies. The force of gravity accurately predicts the planetary orbits, it was used to put the first man on the moon, it predicts the return of comets, the rotation of galaxies, the solar eclipses, artificial satellites, satellite communications and television, the GPS and interplanetary probes. I almost forgot, it is why NASA was established in the first place.The book has an active table of contents for readers to access each chapter,LIFE OF SIR ISAAC NEWTONxivBOOK I.1THE MATHEMATICAL PRINCIPLES OF NATURAL PHILOSOPHY.1AXIOMS, OR LAWS OF MOTION.20OF THE MOTION OF BODIES.43SECTION II.65Of the Invention of Centripetal Forces.65SECTION III.91Of the motion of bodies in eccentric conic sections.91SECTION IV.110Of the finding of elliptic, parabolic, and hyperbolic orbits, from the focus given.110SECTION V.123How the orbits are to be found when neither focus is given.123SECTION VI.171How the motions are to be found in given orbits.171SECTION VII.183Concerning the rectilinear ascent and descent of bodies.183SECTION VIII.202Of the invention of orbits wherein bodies will revolve, being acted upon by any sort of centripetal force.202SECTION IX.212Of the motion of bodies in moveable orbits; and of the motion of the apsides.212SECTION X.230Of the motion of bodies in given superficies, and of the reciprocal motion of funependulous bodies.230SECTION XI.255Of the motions of bodies tending to each other with centripetal forces.255SECTION XII.300Of the attractive forces of sphærical bodies.300SECTION XIII.333Of the attractive forces of bodies which are not of a sphærical figure.333SECTION XIV.353Of the motion of very small bodies when agitated by centripetal forces tending to the several parts of any very great body.353BOOK II.365OF THE MOTION OF BODIES.365SECTION I.365Of the motion of bodies that are resisted in the ratio of the velocity.365SECTION II.381Of the motion of bodies that are resisted in the duplicate ratio of their velocities.381SECTION III.421Of the motions of bodies which are resisted partly in the ratio of the velocities, and partly in the duplicate of the same ratio.421SECTION IV.436Of the circular motion of bodies in resisting mediums.436SECTION V.449Of the density and compression of fluids; and of hydrostatics.449SECTION VI.469Of the motion and resistance of funependulous bodies.469SECTION VII.507Of the motion of fluids, and the resistance made to projected bodies.507SECTION VIII.571Of motion propagated through fluids.571SECTION IX.600Of the circular motion of fluids.600BOOK III.619RULES OF REASONING IN PHILOSOPHY.621PHÆNOMENA OR APPEARANCES.625PROPOSITIONS634OF THE MOTION OF THE MOON'S NODES.724END OF THE MATHEMATICAL PRINCIPLES.863THE SYSTEM OF THE WORLD.865
