Keeping Myth Memory Alive: The Usual and the Unusual in Sudha Murty’s Unusual Tales Series

If myth is vital to a community, its memory must be kept alive. But how, is the question? Is it always prudent to remain faithful to the ‘original’ version of the received myth, or is it desirable to tamper with, or destabilize, the source myth? In India, mainstream versions of the Ramayana and the Mahabharata have long been disrupted by folk, feminist, and queer adaptations. Reversions of these oral, transhistorical master narratives of Hinduism have made a resurgence in a post-independence India that is precariously perched between tradition and modernity, and hence more acutely desirous that its children veer closer to their roots, or so the flourishing market for myth retellings for children suggests. Amongst this incandescent body of literature is Sudha Murty’s series of five books that revisits popular stories about the gods and goddesses of the Hindu pantheon — The Serpent’s Revenge: Unusual Tales from the Mahabharata (2016), The Man from the Egg: Unusual Tales about the Trinity (2017), The Upside Down King: Unusual Tales about Rama and Krishna (2018), The Daughter from a Wishing Tree: Unusual Tales about Women in Mythology (2019), and The Sage with Two Horns: Unusual Tales from Mythology (2021). This paper explores how these tales of antiquity, refracted and reconstructed through the author’s own personal memory, intersect with the more public and collective myth memory of the community. In reviewing Murty’s retrieval of myths by reimagining and re-situating the ‘evidentiary traces’ of myth in the here and now for the children of today, it interrogates how, if at all, the retold myths counter the metanarratives of gender, religion, culture and perhaps, history too. Finally, it argues that the genre of myth retelling must go beyond simply reviving myth memory to destabilizing myth by ‘fiddling ‘with the sacred, especially when adapted for children.

CRITICISM OF THE “THEORY OF INCANDESCENT SURFACE IGNITION” BY Ya.B. ZELDOVICH. SELF-IGNITION OF INFINITE FUEL BY INCANDESCENT BODIES

The basic principles of thermal explosion were studied and outlined by 1980. It seemed that fundamental research had been completed, but in 1984 A.A. Filippov discovered that the “ignition” condition obtained by Ya.B. Zeldovich did not correlate with the data of the experiment on ignition of a gas mixture by incandescent cylinders. Since Zeldovich’s “Theory of Incandescent surface ignition” has long been the basis of the ignition theory, its analysis was carried out and an error was found. It is proved that the above-mentioned work is not related to ignition, but to the self-ignition of infinite fuel. It is shown that a thermal explosion of fuel from an incandescent body can develop not only as ignition, but also as self-ignition. The conditions of self-ignition of infinite fuel by a flat surface and a cylinder are given, as well as the probable condition of ignition of fuel between parallel walls of different temperatures.

The Progress of Black Holes: Principles & Physical Detection Technology

Humans have been trying to explain black holes since the 19th century, using theoretical understanding and observations of the universe. Incandescent body thermal radiation has been the focus of extensive theoretical and experimental research for over a century. This paper will discuss the concept of a black hole and use information retrieval to generate a panoramic image of it. The content illustrates black holes from three different perspectives: description of black holes using mathematical methods and data, models, and detection. A black hole is a controversial object, and no one knows for sure what it is. Indeed, multiple numerical simulations have been carried out to investigate the critical behaviors of black holes with various geometrical configurations in arbitrary dimensions. We will sum up the black hole knowledge so far and discuss the recent progress in terms of black hole exploration, i.e., shed light for future black holes model construction and detection.

Application of Cassini ovals for the formation of the 24-hour light attention of the runway

The object of research is the process of ensuring 24-hour compliance with the technical specifications of the aerodynamic runway illumination. Under these conditions, the existence of a diffuse structure of the process of heat transfer of the working fluid and light radiation is explained.One of the most problematic places is the complexity of manufacturing and the sufficiently large material intensity of the tungsten incandescent body and the subsequent control of compliance of the incandescent body with the requirements of Cassini ovals.In the course of the study, mathematical analysis of eight-shaped fourth-order algebraic curves is done. Cassini oval and represent a generalization of a separate case, was made by the Bernoulli lemniscate «Bernoulli flower». «Eight-shaped» Cassini ovals form a geometric location of points whose product of distance, to two fixed points, focuses, remains unchanged. Conformity analysis was conducted to check the required diffuse structure of the heat transfer of the working fluid and the light scale generated by it, which does not take place in the known designs of incandescent lamps.The feasibility of using the landing zone on the runways of the incandescent tungsten body in the form of a conductive «Cassini oval» is analyzed in the signal lights. Attention is drawn to the possibility of forming a diffuse structure of heat flux and light radiation. The prospects for increasing the reliability and durability of illuminating the runway signal lights are explained. The principles of choice of mass-dimensional characteristics of the working body of incandescent signal lights are substantiated.Two further forms of Cassini ovals were obtained with the initially unchanged product being performed, in particular, the Cassini output oval deformed inside, as well as the case of the Cassini output oval falling into two autonomous ovals around the focuses.The heated tungsten conductive «Cassini oval» emits diffuse thermal and light fluxes in all directions of the surrounding space. Due to this, the light triangles in the «Cassini oval» plane, in their totality, will outline the mosaic of radiating elements of equal brightness, and thus create a continuous radiating bright light in the form of an oval plate.

Reading The Road with Paul Ricoeur and Julia Kristeva: The Human Body as a Sacred Connection

Cormac McCarthy’s novel The Road confronts readers with a question: what is there to live towards after apocalypse? McCarthy locates his protagonists in the aftermath of the world’s fiery destruction, dramatizing a relationship between a father and a son, who are, as McCarthy puts it, “carrying the fire.” This essay asserts that the body carrying the fire is a sacred, incandescent body that connects to and with the world and the other, unifying the human and the divine. This essay will consider the body as a sacred connection in The Road. Paul Ricoeur’s hermeneutics and Julia Kristeva’s psychoanalytic approach will help to explore what is sacred. In addition, their works elucidate the body as a present site of human connection and sacredness while calling attention to what is glaringly absent yet hauntingly present in McCarthy’s text: the mother. In the aftermath of destruction, primitive, sacred connections become available through the sensual body, highlighting what is at stake in the novel: the connection of body and spirit. The essay will attempt to show that McCarthy’s rejection of a redemptive framework, or hope in an otherworldly reality, shrouds spirit in physicality symbolized by the fire carried by the body. This spirit offers another kind of hope, one based on the body’s potential to feel and connect to the other. The thought and works of Ricoeur and Kristeva will broaden a reading of McCarthy’s novel, especially as a statement about the unification of body and spirit, contributing a multidimensional view of a contemporary problem regarding what sustains life after a cataclysmic event.

Heat and mass transfer processes in incandescent lamps and development of gas mixtures for their filling

A model of a working gas medium for incandescent lamps (ILs) is described. Within the framework of the molecular-kinetic theory, with the help of Langmuir's concept of a stagnant layer about the incandescent tungsten filament, the mathematical model of heat and mass transfer processes for quasistationary operating conditions of the IL was formulated. In this case, the thermodiffusion contribution to tungsten mass transfer and temperature-dependent transfer coefficients of a working mixture were taken into account. With the solution of the transfer equations, the design formulas for the integral heat flux (loss) from the incandescent body and the integral mass flow of tungsten atoms through a filling gas in the IL containing a cylindrical (spherical) incandescent body were obtained. Based on the calculated heat losses from the incandescent body and mass transfer speed of the tungsten atoms in different gas media, effective compositions of multicomponent filling mixtures (N 2 -Ar-Kr and N 2 -Ar-Kr-Xe) are developed for commonly used bispiral krypton general-purpose ILs. Their applications allow the reduction of the cost of the lamps, while the luminous efficacy and the operating life of the lamps are the same as (or better than) those of lamps with the standard filling mixtures, N 2 -Kr.

The Infra-red Suppression in the Incandescent Light from a Surface with Submicron Holes.

The surface structure of the incandescent body effects on the emissivity of the infra-red light. If an adequate surface structure can suppress the infra-red emission, the efficacy of the incandescent lamp could increase. The main purpose of the present work is to measure the change of the infra-red emission due to the surface structure. Tungsten films with submicron-sized deep holes (the diameter of 2-4 hundreds nanometer and the depth of 2-4 micrometers) were prepared and heating them. The spectra of incandescent light were measured at high temperature up to 1400K. We found that the amount of the infra-red emitted from the surface with submicron holes is almost a half of that from a surface with macroscopic holes.

Part II: Assets and Deficiencies of Available Sources of Radiant Energy for Medical Uses: Practical Suggestions Regarding Sources of Radiant Energy for Medical Uses

The primary natural source of ultraviolet radiation is the sun. Approximately five per cent of this incandescent body's radiation is ultraviolet. The ultraviolet intensity at the earth's surface depends on a number of factors including time of day, time of year, latitude, elevation above sea level, atmospheric turbidity and thickness of the ozone layer.

Tyndall and Stefan's Radiation Law

IN the published account of the 1865 Rede Lecture, On Radiation (Fragments of Science, 1871), John Tyndall describes an experiment showing that a rise in temperature of an incandescent body augments the invisible radiation along with the visible. He tabulates the energy of the obscure radiation for increasing temperatures of his source, a spiral of platinum wire, and describes the appearance of the spiral, though the actual temperatures were not measured.

Observational Clue to the Size of Meteors

CONSIDERABLE difference of opinion prevails concerning the size and mass of meteors. While one school of investigators, attacking the problem from theoretical considerations based on certain relations between amount of light emitted by an incandescent body and its extent of surface and mass, is prepared to give thenucleus of average naked–eye meteors a volume scarcely greater than a few cubic millimetres, another school, consisting mainly of experienced observers, but by no means indifferent to theoretical calculations, argues in favour of much larger dimensions for them—at least several cubic inches. As there is no possibility of observing meteors at close quarters, much less handling them, while on their aerial path, the question has remained undecided.

Volcanologic investigations at Kilauea

The lava column at Halemaumau consists of a main semisolid incandescent body (bench magma), perforated by small shafts leading to a saucer on its summit, which contains a shallow lake of liquid lava. The bench magma grades by decreasing viscosity upward into the lava lake and downward into a more fluid part of the magma column. The top of the bench magma is constantly being added to by overflows from the lava lake and accumulation of foundered crusts. Loading of part of its surface by overflow results in isostatic sinking of that part and a compensating rise of some other part, the latter often producing islands of bench magma in the lava lake. During subsidence, the lake magma sinks more rapidly than the bench magma, leaving the islands of bench magma standing higher than before subsidence took place. The process of island formation is well-illustrated by photo sequences. Jaggar reviews the earlier contributions of Brun, Daly, Perret, Day and Shepherd, and Green on the nature of magmatic gases and describes the flames produced by burning gases.

On the Colours of Double Stars

IF any light whatever has its intensity increased the effect on the eye is to add to the sensation a certain yellow element which I have accurately defined by experiment (Am. Jour. Sci., April, 1877, vol. xiii. p. 247). A red light brightened becomes yellower, a green light yellower, a yellowish white less white, a blue or violet light whiter. The phenomena are described at length in Prof. Rood's “Modern Chromatics.” The fact that an incandescent body becomes less red and more yellow when it is heated is probably due to this physiological principle. That the incandescent body ultimately becomes white is probably owing to some not understood modification of the principle for excessively bright lights.

3. On the Constitution of Flame

In this communication the author discusses the theory of the constitution of flame advanced by Professor Draper of New York, in his paper “On the Production of Light by Chemical Action,” which appeared in the Philosophical Magazine for 1848.Professor Draper refers to experiments which prove that the higher the temperature of an incandescent body, the more refrangible are the rays of light emitted by it. He assumes that the temperature of the outer portions of a flame is greater than that of the interior regions; for outside there is a better supply of oxygen, and hence a more intense combustion is maintained.
