Thoreau’s Rainbow

Author(s):  
Stephen R. Wilk

In his famous book Walden, or Life in the Woods, Henry David Thoreau writes about the experience of walking through a rainbow. Since Thoreau is often praised for the accuracy of his observations of natural phenomena, what are we to make of this plainly unscientific description of a rainbow? A rainbow is a phenomenon that is always about 138 degrees (180 degrees – 42 degrees) away from the sun, and the impossibility of ever reaching it is enshrined in such stories as the Gold at the End of the Rainbow. Was he mistaken, or was he describing an emotional reaction to a natural wonder? And how critical should we be of him?

In view of the principle of actualism the early history of the earth must be explained on the basis of present-day natural phenomena and the basic Laws of Nature. The study of the solar system leads to the conclusion that the planets were formed as by-products when the sun developed from a rotating cloud of cosmic gas and dust. The protoplanets or planetesimals could have accreted as a result of mutual collisions, during which they could have become partly molten so that they could differentiate into a crust, a mantle and a core on the basis of differences in density.

On the basis of the annual pseudo motion of the Sun, there is a division of the seasons. In terms of seasons, there are several natural phenomena that can affect the seasons on earth, especially the natural phenomena of El Nino and La Nina. In Indonesia, El Nino can result in a longer dry season and La Nina can cause a longer rainy season. Thus, any research related to the influence of El Nino and La Nina is very important to do to determine whether these two natural phenomena affect the intensity of determining the direction of the Qibla. This research is included in the Library Research using qualitative research methods with a descriptive format. Data collection techniques used are documentation or literature and non-participant observation. Meanwhile, to analyze the data, the authors processed the field data obtained from the Class I Semarang Climatology Office to obtain the average climatological elements during the year of El Nino and La Nina, then the results were implemented in determining the direction of the Qibla. This study resulted in the finding that La Nina was sufficient to influence the implementation of determining the direction of the Qibla because at the time of La Nina the rain continued to occur throughout the year.

Galileo is an iconic founder of modern science, but his career and his contributions were far more complex than his reputation. He, too, championed a scientific method, but his thinking differed greatly from Bacon’s and Descartes’. Galileo’s method was based on Archimedes’ combination of experiment, mathematics, and deduction. This method allowed Galileo to claim certain knowledge of reality derived from mathematical accounts of natural phenomena. But he also claimed certain knowledge of reality derived directly from observation, as in his assertion that the Earth moved around the sun. While Galileo’s predictions were sometimes correct, he had no criterion for distinguishing between correct and incorrect inferences or for connecting his mathematical deductive reasoning about phenomena to the way they really were.

Åndens hermeneutik. En læsning af “I al sin Glands nu straaler Solen ”[The hermeneutics of the Spirit. A reading of “I al sin Glands nu straaler Solen ”]By Jakob Ulrik HansenThis article takes as its point of departure the question of how Grundtvig in his hymns seems to amalgamate the seasons, the biblical world, legendary material and historical events without reflecting on time. Through a reading of “I al sin Glands nu straaler Solen” (In all its Splendour now the Sun shines), the article discusses what enables this particular form of poetic hermeneutics.The blending of early-summer sun with divine light “Glands” (splendor or doxa) in the beginning of the hymn generates a vision of the world in two levels, which becomes constitutive of the entire hymn. In the following stanza, summer becomes an image of the recovered connection with Paradise through the Pentecostal spirit, e.g. in the breeze through the leaves and the rippling water in the creek. This divine affiliation of the natural phenomena is indicated by various allusions to their provenance in Paradise. The centre of the hymn, stanza 4, relates how the spirit descends and speaks in the world. The spirit, however, does not speak by itself, but as part of the Trinity. Stanza 5 narrates the awakening of the congregation and its assembly for worship, and in stanza 6 all languages merge into a united “Hallelujah”, a word generally reserved for angels. The hymn ends with the description of the glory of God's kingdom.The article concludes that Grundtvig’s amalgamation of events, times and opposites in this hymn presupposes a particular conceptualisation of the spirit, and it leaves as an open question that awaits further study whether this conceptualisation of the spirit and hermeneutics is a central feature in many of Grundtvig’s other hymns.

In this chapter I discuss a series of site-specific sound art works which are designed to act on our sensory system prior to our intellect. These artworks are created from my fascination with natural phenomena and systems coupled with contemporary and historical scientific ideas and discoveries. The artworks are immersive in that the participant enters into the atmosphere and ‘other worldliness’ of the work. These phenomena include the firing patterns of artificial neurons, the multiverse and the ionosphere; the meeting place between the sun and the earth. In this chapter, I draw on Juhanni Pallasmaa’s writing on sensing and perception where evoking multimodal or cross modal cues are a strategy to create atmospheres where artworks are felt rather than thought.

The article describes the use of metaphorical terms of plants in the nature calendars designed for children and young people of school age: Głos przyrody [Voice of Nature] by M. Kownacka and M. Kowalewska (vol. 1–2, 1963) and Razem ze słonkiem [Together with the Sun] by M. Kowalewska (vol. 1–6, 1975–1978). The role of metaphores in three areas is presented: 1) using “child’s cognition”, that is explaining natural phenomena with means referring to children’s imagination, 2) applying elements of humour and fun, 3) using poetic metaphors whose task was to build atmosphere and sublimity in the description of flora. The described stylistic treatments were to make the popular science texts more attractive to young readers, and they were to become the incentive for them to observe nature in parallel with reading adapted to the perception and needs – not only cognitive, but also emotional.

Abstract The arcs of dawn and dusk are natural phenomena that define the boundary of the border between day and night. They are associated with the refraction of solar rays at high angles of incidence that converge to project an arc of light onto the back side of the earth's atmosphere. The rings of dawn and dusk, in turn, are associated with rays, also at large angles of incidence, which converge to project the image of the Sun. Arcs and rings become visible by scattering light by clouds or particles suspended in atmospheric air in the region in which they occur. Here we show a model that describes these natural phenomena and report the first-time record image produced in July of this year.

Greek antiquity, in the text, stretches from the contributions of Thales, in 600 BCE, to that of Eratosthenes in 225 BCE. In large part the Greek-speaking contributors were materialists who sought the principles or “roots” of all natural phenomena, for example, in the “elements” of earth, air, fire, and water. Aristotle (350 BCE), in particular, composed the contributions of his predecessors into a coherent whole or cosmos that answered the questions of his day. Aristarchus (280 BCE), Archimedes (250 BCE), and Eratosthenes (225 BCE) applied simple geometrical relations and ratios of magnitudes to, respectively, the distances of the sun and moon, the concept of static equilibrium, and the diameter of the Earth.

We can be certain that all cultures wondered about the Sun, Moon, planets, and stars, and that they found ways of incorporating what they observed into comprehension of themselves existing within their perceptible surroundings, both on earth and in the sky. Thanks to the gleanings of anthropologists in the late 1800s and early 1900s, we have a treasure trove revealing that the Native American Skidi Band of the Pawnee Nation possessed a unique creation tradition rich in astronomical symbolism. This includes the belief that the two bright planets encompassing within their orbits the orbit of planet Earth were considered by the Skidi to be the cosmic parents of the very first human child, a girl; the Sun and Moon were considered parents of the first male child. This story of human origin includes the legendary journey of the male Great Red Warrior from the east to court the Beautiful Bright White female star of the west, followed by the birth of their daughter transported to earth. This is a striking allegory of the apparent migrations of Mars and Venus, continually changing in brightness, undergoing retrograde motions and sometimes seeming to unite in close conjunctions. Watching these interrelations, repeated over and over with intriguing variations, likely led to and continually reinforced this tradition. Likewise, the apparent monthly relationships of Sun and Moon, with occasional eclipses, visually reinforced the account of the initial male human birth. Thus, the Skidi Pawnee tradition of human origins is an interesting, indeed beautiful, example of human interpretation of natural phenomena.

AbstractThe relationship between religion and science is a hotly debated issue, which has triggered new approaches and redefinitions of fundamental notions worldwide. This paper presents a preliminary sketch of the Manichaean attitude towards natural phenomena, thus exploring the question of the relation of religion to science—even if these notions are not necessarily applicable for early, non-European phenomena—in a historical context. In my survey, I use the Coptic Kephalaia, a fourth-century Manichaean text from Egypt, to highlight some instances (the Sun and the Moon, clouds, vegetation and animals, the salty sea, shadow, and earthquake) that characteristically reflect the unique, early Manichaean attitude to the physical world.
