If there is practice without theory, perhaps there is theory without practice. We have fairly fixed notions of practice without theory—action without reflection, hand-to-mouth existence, meeting problems as they arise, disdain of plans or strategy, and so on. Of theory without practice there seems but one common idea—theory that because of abstraction or irrelevance cannot be applied. Plato told us the story of Thales of Miletus who, gazing at the stars, fell into a well. A little maid laughed to see such sport. Her laughter still rings in our ears, reminding us to practice navigating the earth rather than contemplate the stars.Theory without practice, then, seems to be theory that cannot be applied. Applied to what? Applied to problems. Which problems? Problems that arise among men or in the community. Who there defines a problem? Not to get bogged down at the start, let us say merely that some men do or that some part of the community does.We can also conceive of a theory not being applied because it seems farfetched or too costly or immoral, or because the moment for its need is not yet at hand. These are not the main objections, even though they all have a bearing in one way or another on the ideas we are about to discuss. The main objections are usually the ones already mentioned—theory irrelevant or too abstract. Abstractness, for our purposes, can be dismissed. It means either that the theory cannot be understood—a matter of communication, we assume—or that steps are lacking to bring the theory down to the applied level. We are really back to the question of application. Either a theory has relevance but for one reason or another cannot be put into practice, or it has no relevance at all and that is the end of that.

The paper considers a method for simulating the flight of a multistage rocket in Matlab using Simulink software for control and guidance. The model takes into account the anisotropy of the gravity of the Earth, changes in the pressure and density of the atmosphere, piecewise continuous change of the center of mass and the moment of inertia of the rocket during the flight. Also, the proposed model allows you to work out various targeting options using both onboard and ground‑based information tools, to load information from the ground‑based radar, with imitation of «non‑ideality» of incoming target designations as a result of changes in the accuracy of determining coordinates and speeds, as well as signal fluctuations. It is stipulated that the design is variable not only by the number of steps, but also by their types. The calculations are implemented in a matrix form, which allows parallel operations in each step of processing a multidimensional state vector of the simulated object.

Photography can be used for pleasure and art but can also be used in many disciplines of science, because it captures the details of the moment and can serve as a proving tool due to the information it preserves. During the period of the Apollo program (1969 to 1972), the National Aeronautics and Space Administration (NASA) successfully landed humans on the Moon and showed hundreds of photos to the world presenting the travel and landings. This paper uses computer simulations and geometry to examine the authenticity of one such photo, namely Apollo 17 photo GPN-2000-00113. In addition, a novel approach is employed by creating an experimental scene to illustrate details and provide measurements. The crucial factors on which the geometrical analysis relies are locked in the photograph and are: (a) the apparent position of the Earth relative to the illustrated flag and (b) the point to which the shadow of the astronaut taking the photo reaches, in relation to the flagpole. The analysis and experimental data show geometrical and time mismatches, proving that the photo is a composite.

The notion that the Earth has entered a new epoch characterized by the ubiquity of anthropogenic change presents the social sciences with something of a paradox, namely, that the point at which we recognize our species to be a geologic force is also the moment where our assumed metaphysical privilege becomes untenable. Cultural geography continues to navigate this paradox in conceptually innovative ways through its engagements with materialist philosophies, more-than-human thinking and experimental modes of ontological enquiry. Drawing upon the philosophy of Gilbert Simondon, this article contributes to these timely debates by articulating the paradox of the Anthropocene in relation to technological processes. Simondon’s philosophy precedes the identification of the Anthropocene epoch by a number of decades, yet his insistence upon situating technology within an immanent field of material processes resonates with contemporary geographical concerns in a number of important ways. More specifically, Simondon’s conceptual vocabulary provides a means of framing our entanglements with technological processes without assuming a metaphysical distinction between human beings and the forces of nature. In this article, I show how Simondon’s concepts of individuation and transduction intersect with this technological problematic through his far-reaching critique of the ‘hylomorphic’ distinction between matter and form. Inspired by Simondon’s original account of the genesis of a clay brick, the article unfolds these conceptual challenges through two contrasting empirical encounters with 3D printing technologies. In doing so, my intention is to lend an affective consistency to Simondon’s problematic, and to do so in a way that captures the kinds of material mutations expressive of a particular technological moment.

Este texto pretende discorrer sobre o pensamento de Alberto Torres, um dos mais importantes precursores do pensamento sociológico brasileiro, que viveu o momento da implantação da República (1889), dedicando-se a pensar temas relacionados a educação. Por conta da sua biografia política e intelectual, esteve preocupado com problemas que até então a intelectualidade brasileira não se importava em discutir. Tais problemas giravam em torno da defesa do meio ambiente e da necessidade em demonstrar a importância em se educar o homem do campo, para que ele pudesse proteger e resguardar os recursos naturais provenientes da terra. Procuramos demonstrar também que as ideias de Alberto Torres contribuíram de forma significativa para a origem do Ruralismo Pedagógico.Palavras-chave: Alberto Torres. Ruralidade.

Abstract The Hebrew calendar is a lunisolar calendar. Its months are based on the revolution of the moon about the Earth, as it is said: This is the burnt offering of every new moon throughout the months of the year1 (Num. 28:14) At the present time the moment of the true new moon is approximated mathematically. However during the Second Temple period, the beginning of the new lunar month had to be observed and certified by witnesses. Then the Sanhedrin Court was to make a public proclamation on the first day of the lunar month (ראש חודש). In Mishnah, Tractate Rosh Hashana, Chapter 2 describes the process of communicating the information about the beginning of new month through the chain of beacon fires: “From the Mount of Olives to Sartaba, and from Sartaba to Grofina, and from Grofina to Hauran, and from Hauran to Bet Biltin. From Bet Biltin they did not move, but rather waved back and forth and up and down until he saw the whole of the diaspora before him lit up like one bonfire.”2 Questioning of reliability of the quoted above description, its completeness and exclusiveness of the delineated in the Mishnah route is beyond the scope of the presented research. In this article we’ll apply methods of the geographic information systems (GIS) analysis in order to examine the existed theories regarding localization of Sartaba - the second mentioned station in the chain of beacon fires, reveal their discrepancies and propose an innovative, albeit rather technical, solution for long-known problem.

Acrumpled and broken strand of asphalt rises at the northern edge of Ulan-Ude, wanders through the dark woods of the Khamar-Daban Mountains, and finally settles into a band of fertile bottom land in a narrow stretch of coastal plain approaching the eastern shore of Lake Baikal. A rattly old Toyota van skitters along the road, passing lonely farms and tiny villages that gather up out of nowhere and disappear just as quickly, domed churches that seem miles from any worshipers, and an occasional solitary babushka by the side of the road selling whatever she’s been able to squeeze from the earth or gather in the woods. There are seven of us riding this highway on this raw morning in October of 2000, crammed into the van and bobbing like buoys to its irregular rhythms—James and me from Boston, our guide Andrei Suknev, his colleague Igor and our driver Kim, all from the city of Ulan-Ude, and two young women who have also signed on with Andrei for a few days—Elisa, from France, and Chanda, from Canada. We’re all eating pine nuts that we bought from one of those women at a wide spot in the road—they’re called orekhi here—and washing them down with lemon soda from a huge plastic bottle. Andrei is showing us how to crack open the nuts’ hard shells with our front teeth and excavate their soft and pungent meat with our tongues. At an austere restaurant in a tiny village that Andrei tells us is called “Noisy Place,” we eat a lunch of rice and some sort of meat, dry bread, and a peculiar variation on borshch, and we pee in an outhouse across the road. We get back in the van and rumble on. We’re heading for a remote national park on Baikal’s eastern shore, but at the moment I’m not quite sure where we’re going. I’d asked Andrei to take us hiking and camping on the lakeshore, to introduce us to local residents, communities, and culture. He’s promised to do that, but he hasn’t provided much beyond the barest details, and none of us has been asking for more.

This paper describes two methods by which lines of position may be obtained by observation of stars (in pairs) without the use of instrumental scale readings either for altitude or for azimuth. These lines of position represent arcs of great circles of the Earth. An instantaneous observation is proposed.Great circles determined by star positions form, on the celestial sphere, a lattice which is not deformed by precession. Whether or not he be at rest relative to the rotating Earth, the observer's zenith traverses this lattice, which thus may serve in celestial navigation precisely as does a well-marked terrain in contact flying over land, or as do ranges and markers in coastal and harbour navigation. Observation of the zenith-transit of an element of this lattice is akin to the process of noting the moment when an aircraft crosses a coastal line or other visible terrestrial mark or to the recognition of when a vessel near shore is on a certain range. Observation of this type is as rapid as the navigator may be able to make it since it is the observation of the occurrence of an instantaneous situation.

AbstractCharles de Foucauld (1858-1916) certainly never envisioned himself as a missionary at the moment of his conversion. He was a contemplative who wanted to live for God alone in imitation of the hidden life of Jesus at Nazareth. But this same concept of Nazareth that became the lens through which he saw his relationship with God and his place in the world became a dynamic force that evolved over the course of the years. Charles' evolving understanding of this took him from Trappist monk, to hermit, to what he called a "missionary monk." He came to believe that a contemplative life lived in close proximity with others could be a living sign of the love of God. His past life experiences played no small part in the way he saw presence and goodness as a means of "shouting the Gospel by one's life" and in his eventual mission among the Muslim people of the Sahara. Charles clearly set out to convert them according to the model of evangelization in his day. But his own ongoing conversion and growing friendships, as well as his extensive study of the language of the Tuareg, among whom he lived, developed into a model of mission based on friendship and respect, where the "other" becomes "brother and sister" and where evangelization is about communion and solidarity as a sign of the Reign of God.


A cyclic process of refining models of the mechanical structure of the Earth and models of the mechanism of one or more earthquakes is developed. The theory of the elastic-gravitational free oscillations of the Earth is used to derive procedures for resolving nearly degenerate multiplets of normal modes. We show that a global network of seismographs (W.W.S.S.N.) permits resolution for angular orders l ≤ 76 and for frequencies a) w ≤ 0.090 s -1 . The peak or centre frequency of each nearly degenerate multiplet is interpreted to be a gross Earth datum. Together, the data are used to refine models of the mechanical structure of the Earth. The theory of free oscillations is used further to derive procedures for retrieving the mechanism, or moment tensor, of an earthquake point source. We show that a globa network of seismographs permits retrieval for frequencies 0.0125 s-1 ≤ w ≤ 0.0825 s-1 . We show that refined models of structure and mechanism lead to improved resolution and retrieval, and that an array of sources further complements the resolution of multiplets. We present a ‘standardized dataset’ of 1064 distinct, observed eigenfrequencies ol the elastic-gravitational free oscillations of the Earth. These gross-Earth data are compiled from 1461 modes reported in five studies: 2 modes reported by Derr (1969), 159 modes observed by Brune & Gilbert (1974), 240 modes observed by Mendiguren ( 1973), 248 modes observed by Dziewonski & Gilbert (1972,1973) and 812 modes reported here. It is our opinion that the establishment of a standardized dataset should precede the establishment of a standardized model of the Earth. Two new Earth models are presented that are compatible with the modal data. One is derived from model 508 (Gilbert & Dziewonski 1973) and the other from model B1 (Jordan & Anderson 1974). In the outer core and in the lower mantle, below a depth of about 950 km, the differences between the two models are negligibly small. In the inner core there are minor differences and in the upper mantle there are major differences in detail. The two models and the modal data are compatible with traditional ray data, provided that appropriate baseline corrections are made to the latter. The source mechanisms, or moment tensors, of two deep earthquakes, Colombia (1970 July 31) and Peru-Bolivia (1963 August 15), have been retrieved from the seismic spectra. In both cases the moment tensor possesses a compressive (implosive) isotropic part. There is good evidence that isotropic stress release begins gradually, over 80s before the origin time derived from the onset of short-period P and S waves. During the process of stress release the principal axes of the moment rate tensor migrate. The axis of compression is relatively stable, the compressive stress rate is dominant, and the other two axes rotate about the axis of compression. We speculate that earthquakes, occurring deep within descending lithospheric plates, are not sudden shearing movements alone but do exhibit compressive changes in volume such as would be associated with a phase change. We further speculate that compressive changes in volume may occur without sudden shearing movements, that there may be ' silent earthquakes’.

Zircons in zonal dunite-clinopyroxenite massifs represent a bank of isotopic data on the brightest moments in the life of his generations in the range up to 3 billion years. The chronological coincidence of the set of such dating forms distinct “family” clusters with reference homologous series of “named” impact events in strict galactic periodicity leads us to the unequivocal conclusion that these coincidences are a natural manifestation of galactic periodicity (with a period of 215 Ma) of all endogenous and impact events in the history of the Earth since the origin of the Earth-Moon system 4.515 billion years ago [20, 9]. The zonal dunite-clinopyroxenite massifs turn out to be the richest archives of isotopic information about the age and transformations of the Earth’s substance almost from the moment of its birth in the Hadean in bowels of the Earth.
