Ever since the time of Newton, his explanation of the general phenomena of the tides by means of the action of the moon and the sun has been assented to by all philosophers who have given their attention to the subject. But even up to the present day this general explanation has not been pursued into its results in detail, so as to show its bearing on the special phenomena of particular places,—to connect the actual tides of all the different parts of the world,—and to account for their varieties and seeming anomalies. With regard to this alone, of all the consequences of the law of universal gravitation, the task of bringing the developed theory into comparison with multiplied and extensive observations is still incomplete; we might almost say, is still to be begun. Daniel Bernoulli, in his Prize Dissertation of 1740, deduced from the Newtonian theory certain methods for the construction of tide tables, which agree with the methods still commonly used. More recently Laplace turned his attention to this subject; and by treating the tides as a problem of the oscillations rather than of the equilibrium of fluids, undoubtedly introduced the correct view of the real operation of the forces; but it does not appear that in this way he has obtained any consequences to which Newton’s mode of considering the subject did not lead with equal certainty and greater simplicity; moreover by confounding, in the course of his calculations, the quantities which he designates by λ and λ', the epochs of the solar and lunar tide (Méc. Cél. vol. ii. p. 232. 291.), he has thrown an obscurity on the most important differences of the tides of different places, as Mr. Lubbock has pointed out.

The day of the month is noted according to the nautical account, which therefore in all observations noted P. M. is one day forwarder than the civil account. The latitude in is deduced from the last preceding meridian altitude of the Sun; and the longitude in is corrected by the last observations of the distances of the moon from the Sun and stars.

Abstract The phoenix (ʿanqā) appears in the philosophy of Avicenna (d.1037) as his example of a “vain intelligible,” a fictional being that exists in the soul, but not in the world. This remarkable bird is notable (along with the Earth, the moon, the sun, and God) for being a species of one. In this essay, I read the poetry Bedil of Delhi (d.1720) in conversation with the philosophical system of Avicenna, arguing that the phoenix in Bedil’s own philosophical system functions as a key figuration that allows him simultaneously to articulate rigorous impersonal systematic ideas and to document his individual first-personal experiences of those ideas. The phoenix also plays a metaliterary role, allowing Bedil to reflect on this way of doing philosophy in the first person—a method founded on the lyric enrichment of Avicennan rationalism. Paying attention to the adjacencies between poetry and philosophy in Bedil, this essay traces the phoenix’s transformations from a famous philosophical example into one of Bedil’s most striking figurations in his arguments about imagination, mind, and self.

When Edward Johnson needed to express his deepest hopes about history, he found in the Bible an encoded emblem for the destiny of America. In the proclamation from Christ's herald that begins The Wonder-Working Providence of Sions Saviour in New England, he concludes with an urgent appeal to all believers:Pray, pray, pray, pray continually with the valiant worthy Joshua that the Sun may stand still in Gibeon, and the Moone in the vally of Aijalon, for assuredly although some small battailes may be fought against the enemies of Christ, yet the great day of their finall overthrow shall not come till the bright Sonne of that one cleare truth of Christ, stands still in the Gentile Churches, that those who fight the Lords Battells may plainly discerne his enemies in all places, where they finde them, as also such as will continue fighting must have the World kept low in their eyes, as the Moon in the valley of Aijalon.

If the actions of the Sun and the Moon upon the different parts of the earth were equal; of if the earth itself were perfectly spherical, and of an uniform density from the center to the surface; in either case the attractions of those remote bodies would have no effect on the position of the terrestrial equator, and the equinoctial points would constantly be the same in the heavens.

On the morning of Saturday, January 24th, 1925, there occurred a spectacle in the Heavens which few men are fortunate enough to experience even once in a lifetime. I was one of the elect on this occasion. The world awoke that morning a stage perfectly set for the wonderful sight nature had arranged. The atmosphere was absolutely clear, no trace of a cloud was visible anywhere and the sun seemed to he unusually bright—flushed with excitement over the performance it and the moon were to enact that day.

The creator, the Creator, the creator, by whatever name, calls the ultimate power that colors the sky blue, the earth green, the sun gold and the moon silver. The colors of Pushpavali in the forest division are countless and the colors of water creatures in the ocean are amazing. Colorless water is also the miracle of the same and the white, black and red color of Ganga, Yamuna and Saraswati is also an expression of the same. Some also create 'Kavirmanishi Paribhu Swayambhu', the poet of the world of life, nature's colors with full sensibility Does. In poetry, there are mainly three basic colors - white, black, white, black and red. सृष्टा, रचेता, विधाता जिस भी नाम से पुकारें उस परम शक्ति को जो आकाश को नीला, धरती को हरा, सूरज को स्वर्ण और चाँद को रजत रंग में रंग देता है। वन प्रान्तर में पुष्पावलि के रंग अनगिनत है और सागर में जल-जीवों के रंग अद्भुत। रंगहीन जल भी उसी का चमत्कार है और गंगा, यमुना और सरस्वती का श्वेत, श्याम और लाल रंग भी उसी की अभिव्यक्ति है।कवि भी रचेता है ‘कविर्मनीषी परिभू स्वयंभू’ जीवन के जगत के, प्रकृति के रंगो को कवि पूरी संवेदन शीलता से संयोजित करता है। काव्य में मुख्य रूप से तीन रंग आधारभूत रंग है- श्वेत, श्याम, रतनान-सफेद, काला और लाल।

Abstract This article explores a probable motivation for the insertion of the Pericope Adulterae (John 7:53–8:11) in the Gospel of John in consideration of the motive of ‘living/life’ used by the gospel writer. Using John 8:12 as the starting point of this investigation, the article focuses on the warning to the Israelites against idolatry with specific attention to the warning against worshiping the sun, the moon, and the stars (Deuteronomy 4:15–20). It also deals with the Feast of Tabernacles, which is the direct context in which Jesus declared that he is the light of the world. The water ceremony also plays a central role in understanding the bigger picture that unfolds, as well as the Early Church’s struggle against heretical Christological teachings of who Jesus was with regard to his human nature and his divine nature.

Seasons (Ritus) are the inherent global earth clock and the rhythm of the world. As per Ayurveda year is divided into six seasons, in which three season Shishira, Vasanta and Greeshma are known as Aadanakala . Other three seasons Varsha, Sharad and Hemanta are said to be Visargakala. In Visarga kala, as the Sun is located in southwards position, its heat reduces or slows down due to the effect of time and its position with respect to the Earth, wind, cloud and rain. The power of the Moon is predominant. Rainwater decreases the heating effect of nature. All of these lead to the predominance of non- dryunctuous, amla (sour), lavana (salty), and madhura (sweet) rasa respectively and step by step rise of body strength in human beings during these three seasons. Out of all the Ritus, Hemanta Ritu is a unique Ritu in terms of having uttam bala. Falling in Dakshinayana, moon is very powerful than sun, Madhur rasa is predominant in this Ritu, so the strength (Bala) of person enhances during this period. This article focuses to disclose thorough review of literature of Hemant ritucharya and its implication towards maintenance and enhancement of Uttam Bala. In Ayurveda oja, veerya, prana, kapha etc terms are considered as synonyms of Bala. Besides prakruti(genetic), sara(physiological) and aahar(diet), kala (season) is one of the prime factors to govern the Bala of the person. Bala stands for the strength of the body in terms of physical, mental, immunological and resistance to the body, the word Bala is being used in different contexts to denote various aspects accordingly. Keywords: Visarga kala, Hemant ritu, Bala
