Comets are distinguished from the planets not only by the peculiarities that immediately strike the eye, but likewise by the circumstances attending their motion in the heavens. All the planets move round the sun in orbits nearly circular; they never deviate far from the ecliptic on either side; and they move in a manner not extremely irregular, and in one direction, according to the order of the signs in the zodiac. Comets, on the contrary, when they first come into view, assume gradually greater degrees of brightness, which they again lose by like gradations, and then disappear; thus seeming to visit the neighbourhood of the sun for a short time only, after which they retire into the immensity of space: they are seen in all quarters of the heavens: and their motion is exceedingly various and irregular; confined to no direction; sometimes greatly curved, and often hardly distinguishable from a rectilineal course. If, to phenomena so dissimilar, we add the prejudice which almost universally prevailed, that comets have only a temporary existence, and are produced by occasional causes, we shall not perhaps have much reason to be surprised that the true account of those bodies, which represents them as forming a part of the same system with the planets, eluded the sagacity of Kepler, to whom we are indebted for the first accurate knowledge of the laws of the planetary motions. This step in our knowledge of the universe was reserved for Sir Isaac Newton. The principal and leading discovery of that great philosopher consisted in generalizing the laws of Kepler; in proving that they are necessary consequences of a more general fact, namely, that all the planets are continually deflected from a rectilineal motion towards the sun in the inverse proportion of the squares of their distances from that body. He demonstrated that the motions of such a system of bodies must be performed in the conic sections, having the sun in the focus, the species of the curve depending upon the proportion of the rectilineal velocity to the quantity of the deflection towards the common centre. This theory comprehends an infinite variety of motions, all flowing from one common principle; and the ellipse alone, by the changes of form which it undergoes according to the degrees of its eccentricity, seems, at one extreme, when it is greatly elongated, as well adapted to account for the phenomena of the comets, as it is, at the other extreme, when it differs little from a circle, to represent the motions of the planets.

Color is the soul of the picture, human attachment to colors has been there since time immemorial. The prevalence of colors is very old in Indian civilization and culture. Colors indicate our happiness in life, our companions. Their sixth is scattered around on social festivals. Rangoli is made at the entrance on the occasion of auspicious work or guest arrival. Colors fill our life with happiness and energy. Indian spirituality is also drenched with different colors. Many colors are present in the universe. The basis of Indian color psychology is nature. In nature, we see many colors in the sky, some of which appear to be anti-nature. Human attraction to colors has never diminished, from primitive cavities to modern humans took the support of colors (varnas) in the development of beauty. The human mind has always been eager to know the secret of colors. In 1670, a scientist named 'Sir Isaac Newton' first removed the mystery of the origin of colors. He believes that the color (color) originates from light. 1 All the colors that appear in nature are different parts of light. Realization comes from sunlight, that is, sunlight is considered to be the origin of colors. It is well known that there are seven colors in sunlight, but these seven colors are not visible to us because the earth revolves around the sun. And because of this rotation, these seven colors are not visible, all these colors are grouped in seven colors, which are not visible, but appear in the form of light (sunshine), seven colors of the rainbow in the sky in the rainy days. can be seen. The color scheme continues to develop along with the development of culture. Man seems to be absorbed in the color scheme from time immemorial. He enjoys developing his colors with culture, civilization. From the early twentieth century, artists began to use colors in a more developed form. रंग चित्र की आत्मा है, रंगों के प्रति मनुष्य आसक्ति आदिम समय से ही रहा है। भारतीय सभ्यता एवं संस्कृति में रंगों का प्रचलन बहुत पुराना है रंग हमारे जीवन के साथी, ये हमारे सुखों को इंगित करते हैं। सामाजिक उत्सवांे-पर्वों पर इनकी छठा चारों ओर बिखरी होती है। शुभ कार्य हो या अतिथि आगमन पर प्रवेश द्वार पर रंगोली बनाई जाती है रंग हमारे जीवन में खुशी एवं ऊर्जा भर देते हैं भारतीय आध्यात्म भी विभिन्न रंगों से सराबोर है। सृष्टि में अनेक रंग मौजूद हैं भारतीय रंग मनोविज्ञान का आधार प्रकृति है प्रकृति में अनेक रंगों को आकाश में देखते हैं जिनमें से कुछ विरोधी प्रकृति के दिखते हैं। रंगों के प्रति मानव का आकर्षण कभी कम नहीं हुआ, आदिम गुहावासियों से लेकर आधुनिक मानव ने सौन्दर्य के विकास में रंगों (वर्णों) का सहारा लिया। रंगों के प्रति रहस्य जानने के लिए मनुष्य का मन सदैव उत्सुक रहा है। सन् 1670 में ‘सर आइजक न्यूटन’ नामक वैज्ञानिक ने सर्वप्रथम रंगों के उत्पत्ति का रहस्य हटाया उनका मानना है कि वर्ण (कलर) की उत्पत्ति प्रकाश से होती है।1 प्रकृति में जितने भी रंग दिखाई देते हैं वे प्रकाश के विभिन्न अंग हैं प्रकाश की प्राप्ति सूर्य की रोशनी से होती है अर्थात् सूर्य की रोशनी ही रंगों का उद्गम माना गया है यह सर्वविदित है कि सूर्य की रोशनी में सात रंग होते हैं, किन्तु यह सात रंग इसलिए हमें नहीं दिखाई देते हैं कि पृथ्वी सूर्य के चारों ओर चक्कर लगाती है और इसी घूमने के कारण यह सातों रंग दिखाई नहीं पड़ते हैं इन सब रंगों का समूह सात रंग की पट्टीयाॅ होती हैं जो दिखाई नहीं पड़ते हैं, बल्कि प्रकाश (धूप) के रूप में दिखाई देते हैं इन्द्रधनुष के सात रंग वर्षा के दिनों में आकाश में दिखाई देते हैं। संस्कृति के विकास के साथ-साथ रंग योजना भी विकसित होती रहती है। मनुष्य अनादि काल से रंग योजना में लीन दिखाई देता है। उसे अपने रंगों को संस्कृति, सभ्यता के साथ विकास देने में आनन्द आता है। बीसवीं शताब्दी के आरंभ से ही कलाकारों ने रंगों का उपयोग अधिक विकसित रूप में करना शुरू किया।

It is demonstrated by Sir Isaac Newton in the Principia , that it is not the Earth's center, but the common center of gravity of the Earth and Moon, that describes the ecliptic; and that the Earth and Moon revolve in similar ellipses, about their common center of gravity.

This paper is based on the precise inverse cone of Pythagoras 1:3. As in section 1 of this paper, all mathematics presented in this paper is by precise  mathematics equations and the author has maintained by proof that the base numbers constant from which all physics constants can be derived are -1 to 19 ( the value 6 is  as per this paper is the constant for expansion of  all bounded space and 19 is the patent “end value” of the base constant numbers as shown in section 1 and  referenced in this section11). Numbers as created and as placed at the cone of Pythagoras 1:3 are precise manifestation of the numbers of linear composite. However, this paper shows that the invention of designated angles (Trigonometry) is an approximate arbitrary arrangement invented by man, based on the created fixed angle of 90 degrees and is certainly flawed as shown here in this paper. Likewise, any attempts to measure curvature by linear numbers is fraught with much error. The author maintains that “If the atomic density and structure of  meteorites from far space have the same configuration as those found on this earth, then by all created logic , these numbers configuration presented in  these two papers and the book (The God of Papa Einstein and Sir Isaac Newton) are a constant unified theorem of  all the space and mass (  Quantum mechanics) in the universe”. Einstein’s Theory of relativity and all other interstellar phenomena are not addressed in the context of this paper because all this is observed science phenomena and not a physical science, and this paper deals with precise numbers configuration as in the section 1 of the paper. Einstein’s relativity is a real observed natural phenomenon, not science by itself, it is a natural aberration of the fact that observed relativity is due to inherent curvature and linear relationship between any two points in the universe and because of the spiral progression of curved space. Neither does light bend it appears to bend, nor does time really dilate in real terms even though it is a real observed phenomenon, neither numbers or distances dilate by any continuum, unfortunately, that is why Einstein’s misconception about time dilation is a Theory and will always be Theory.

Spectrum analysis may perhaps be said to date from the year 1666 when Sir Isaac Newton discovered that rays of light of different colors are of different refrangibility. Later he discovered that a beam of white light coming from a small round opening and passed through a prism would be spread out into a band of color. Fraunhoffer in 1823 substituted for the round hole a narrow slit, and found that in the case of the sun the band of color was crossed by many fine dark lines. He also turned the instrument on some of the brighter stars, and found their spectra in general different from that of the sun. For example some showed bright lines. But the true explanation of the bright and dark lines remained a mystery until the announcement in 1859 of Kirchoff's famous law.


The Professor observes, that Sir Isaac Newton was the first mathematician who endeavoured to estimate the quantity of the precession from the attractive influence of the sun and moon on the spheroidal figure of the earth. His investigations relating to this subject evince the same transcendent abilities that are displayed in other parts of his Principia; but it is admitted, that, from a mistake in his process, his conclusion is erroneous. The investigations of other mathematicians in attempting the solu­tion of the same problem are arranged by the author under three general heads. The first arrive at wrong conclusions, in consequence of mistake in some part of their proceedings; the second obtain just conclusions, but rendered so by balance of opposite errors; the third approach as near the truth as the nature of the subject will admit, but, in the author’s estimation, are liable to the charge of obscurity and perplexity.

In 1614 the Jesuit astronomer Christoph Scheiner and his student, Johann Georg Locher, proposed a physical mechanism to explain how the Earth could orbit the sun. An orbit, they said, is a perpetual fall. They proposed this despite the fact that they rejected the Copernican system, citing problems with falling bodies and the sizes of stars under that system. In 1651 and again in 1680, Jesuit writers Giovanni Battista Riccioli and Athanasius Kircher, respectively, considered and rejected outright this idea of an orbit as a perpetual fall. Thus this important concept of an orbit was proposed, considered, and rejected well before Isaac Newton would use an entirely different physics to make the idea that an orbit is a perpetual fall the common way of envisioning and explaining orbits.

Dear Sir, The discovery of the polarisation of light by reflexion, con­stitutes a memorable epoch in the history of optics; and the name of Malus, who first made known this remarkable pro­perty of bodies, will be for ever associated with a branch of science which he had the sole merit of creating. By a few brilliant and comprehensive experiments he established the general fact, that light acquired the same property as one of the pencils formed by double refraction, when it was reflected at a particular angle from the surfaces of all transparent bodies: he found that the angle of incidence at which this property was communicated, was greater in bodies of a high refractive power, and he measured, with considerable accuracy, the polarising angles for glass and water. In order to discover the law which regulated the phenomena, he com­pared these angles with the refractive and dispersive powers of glass and water, and finding that there was no relation be­tween these properties of transparent bodies, he draws the following general conclusion. “The polarising angle neither“ follows the order of the refractive powers, nor that of the “dispersive forces. It is a property of bodies independent“ of the other modes of action which they exercise upon “light.“ This premature generalisation of a few imperfectly ascer­tained facts, is perhaps equalled only by the mistake of Sir Isaac Newton, who pronounced the construction of an achromatic telescope to be incompatible with the known principles of optics. Like Newton, too, Malus himself aban­doned the enquiry; and even his learned associates in the Institute, to whom he bequeathed the prosecution of his views, have sought for fame in the investigation of other properties of polarised light.

If the attraction of gravity be exerted, as Sir Isaac Newton supposes, not only between the large bodies of the universe, but between the minutest particles of which these bodies are composed, or into which the mind can imagine them to be divided, acting universally according to that law, by which the force which carries on the celestial motions is regulated; namely, that the accelerative force of each particle of matter towards every other particle decreases as the squares of the distances increase, it will necessarily follow, that every hill must, by its attraction, alter the direction of gravitation in heavy bodies in its neighbourhood from what it would have been from the attraction of the earth alone, considered as bounded by a smooth and even surface. For, as the tendency of heavy bodies downwards perpendicular to the earth's surface is owning to the combined attraction of all the parts of the earth upon it, so a neighbouring mountain ought, though in a far less degree, to attract the heavy body towards its centre of attraction, which cannot be placed far from the middle of the mountain.

In his Principia (1687), Sir Isaac Newton laid out his discovery of the laws of motions and the law of universal gravitation. His historic journey involved a critical moment when, aided by discussions with Robert Hooke, he conquered the challenge of circular motion, e.g. one body circling another, by introducing the concept of force. The Principia was a tour-de-force demonstration of the intelligibility of the universe and ultimately broke physics away from philosophy. This work led directly to the concept of energy.

Accidents and occupational diseases; It causes loss of physical and mental health for employees and high amounts of income loss for employers and countries. In order to prevent all these losses from happening, technical and engineering measures are not enough and an internalized safety culture perception is required in management and employees. The common principle in order to protect it from accidents and diseases is to ensure that the employees act with safety awareness at every moment of the work, with the understanding of safety culture, which is defined as the set of values and rules, under the leadership of the management. Behavior and attitude patterns that do not change in a short time are shown as the main causes of accidents in business life. It is essential to create a culture that embraces safe behavior patterns and, as a result, a safe work environment created to prevent these accidents. In the implementation of this culture, the employees should be included in the process at every stage. In the study, a literature review on safety culture as a preventive factor in occupational accidents was carried out. As a result of the research, it was determined that the most appropriate method in the long-term in the prevention and reduction of accidents is the safety culture.
