  • The Sundial, Beyond the Form and Time
    ISAMA BRIDGES The International Society of the Mathematical Connections Arts, Mathematics, and Architecture in Art, Music, and Science The Sundial, Beyond the Form and Time ... Andrzej Zarzycki 227 Brighton Street Belmont, MA 02478 E-mail: [email protected] Abstract Architecture (iir" k 1-t].lk" ch ... r) n. 1. The art and science of designing and erecting buildings. Can a building inspire scientific thinking? Can an architectural structure reflect the complexity of the universe? Is there a relationship between the artistic and scientific? This paper discusses an approach to design, which uses an architectural structure as a research apparatus to pursue scientifically driven beauty. Architecture could be defined as the man-made universe - the universe whose primary function was to shelter us from elements, animals and other people. Broadly speaking, to protect us from the "outer Uni­ verse". It is not surprising that the evolution of architecture follows the same trajectories as the evolution of our thinking and perception ofthe surrounding world. However, somewhere along the lines of history, archi­ tecture acquired another purpose and began to playa new role in our self-awareness. In ancient, medieval and even modem times, we have viewed architecture as a medium to express, symbolize, and address the meaning of our existence. Ancient temples reveal an intimate knowledge of geometry and human perception by purposefully distorting their forms to balance visual illusions. Medieval cathedrals manifested greatness of God through art and structural achievements, while contemporary monu­ ments address the social and philosophical aspirations of a present-day society. As a result of this centuries long evolution~ we now associate architecture with its less utilitarian and more symbolic values.

    Basic principles of celestial navigation James A. Van Allena) Department of Physics and Astronomy, The University of Iowa, Iowa City, Iowa 52242 ͑Received 16 January 2004; accepted 10 June 2004͒ Celestial navigation is a technique for determining one’s geographic position by the observation of identified stars, identified planets, the Sun, and the Moon. This subject has a multitude of refinements which, although valuable to a professional navigator, tend to obscure the basic principles. I describe these principles, give an analytical solution of the classical two-star-sight problem without any dependence on prior knowledge of position, and include several examples.

  • What Time Is It?
    The Astronomical League A Federation of Astronomical Societies Astro Note E3 – What Time Is It? Introduction – There are many methods used to keep time, each having its own special use and advantage. Until recently, when atomic clocks became available, time was reckoned by the Earth's motions: one rotation on its axis was a "day" and one revolution about the Sun was a "year." An hour was one twenty-fourth of a day, and so on. It was convenient to use the position of the Sun in the sky to measure the various intervals. Apparent Time This is the time kept by a sundial. It is a direct measure of the Sun's position in the sky relative to the position of the observer. Since it is dependent on the observer's location, it is also a local time. Being measured according to the true solar position, it is subject to all the irregularities of the Earth's motion. The reference time is 12:00 noon when the true Sun is on the observer's meridian. Mean Time Many of the irregularities in the Earth's motion are due to its elliptical orbit. In order to add some consistency to the measure of time, we use the concept of mean time. Mean time uses the position of a fictitious "mean Sun" which moves smoothly and uniformly across the sky and is insensitive to the irregularities of the Earth’s motion. A mean solar day is 24 hours long. The "Equation of Time," tabulated in almanacs and represented on maps by the analemma, provides the correction between mean and apparent time to allow for the eccentricity of the Earth's orbit.

    316 DOWNES ON LONGITUDE IN LAXD SUIWETISG. [Selected (Paper No. 3027.) The Determination of Longitude in LandSurveying.” By ROBERTHENRY BURNSIDE DOWSES, Assoc. M. Inst. C.E. THISPaper is presented as a sequel tothe Author’s former communication on “Practical Astronomy as applied inLand Surveying.”’ It is not generally possible for a surveyor in the field to obtain accurate determinationsof longitude unless furnished with more powerful instruments than is usually the case, except in geodetic camps; still, by the methods here given, he may with care obtain results near the truth, the error being only instrumental. There are threesuch methods for obtaining longitudes. Method 1. By Telrgrcrph or by Chronometer.-In either case it is necessary to obtain the truemean time of the place with accuracy, by means of an observation of the sun or z star; then, if fitted with a field telegraph connected with some knownlongitude, the true mean time of that place is obtained by telegraph and carefully compared withthe observed true mean time atthe observer’s place, andthe difference between thesetimes is the difference of longitude required. With a reliable chronometer set totrue Greenwich mean time, or that of anyother known observatory, the difference between the times of the place and the time of the chronometer must be noted, when the difference of longitude is directly deduced. Thisis the simplest method where a camp is furnisl~ed with eitherof these appliances, which is comparatively rarely the case. Method 2. By Lunar Distances.-This observation is one requiring great care, accurately adjusted instruments, and some littleskill to obtain good results;and the calculations are somewhat laborious.

  • Dead Reckoning and Magnetic Declination: Unveiling the Mystery of Portolan Charts
    Joaquim Alves Gaspar * Dead reckoning and magnetic declination: unveiling the mystery of portolan charts Keywords : medieval charts; cartometric analysis; history of cartography; map projections of old charts; portolan charts Summary For more than two centuries much has been written about the origin and method of con- struction of the Mediterranean portolan charts; still these matters continue to be the object of some controversy as no one explanation was able to gather unanimous agreement among researchers. If some theory seems to prevail, that is certainly the one asserting the medieval origin of the portolan chart, which would have followed the introduction of the marine compass in the Mediterranean, when the pilots start to plot the magnetic directions and es- timated distances between ports observed at sea. In the research here presented a numerical model which simulates the construction of the old portolan charts is tested. This model was developed in the light of the navigational methods available at the time, taking into account the spatial distribution of the magnetic declination in the Mediterranean, as estimated by a geomagnetic model based on paleomagnetic data. The results are then compared with two extant charts using cartometric analysis techniques. It is concluded that this type of meth- odology might contribute to a better understanding of the geometry and methods of con- struction of the portolan charts. Also, the good agreement between the geometry of the ana- lysed charts and the model’s results clearly supports the a-priori assumptions on their meth- od of construction. Introduction The medieval portolan chart has been considered as a unique achievement in the history of maps and marine navigation, and its appearance one of the most representative turn- ing points in the development of nautical cartography.

  • Sidereal Time Distribution in Large-Scale of Orbits by Usingastronomical Algorithm Method
    International Journal of Science and Research (IJSR) ISSN (Online): 2319-7064 Index Copernicus Value (2013): 6.14 | Impact Factor (2013): 4.438 Sidereal Time Distribution in Large-Scale of Orbits by usingAstronomical Algorithm Method Kutaiba Sabah Nimma 1UniversitiTenagaNasional,Electrical Engineering Department, Selangor, Malaysia Abstract: Sidereal Time literally means star time. The time we are used to using in our everyday lives is Solar Time.Astronomy, time based upon the rotation of the earth with respect to the distant stars, the sidereal day being the unit of measurement.Traditionally, the sidereal day is described as the time it takes for the Earth to complete one rotation relative to the stars, and help astronomers to keep them telescops directions on a given star in a night sky. In other words, earth’s rate of rotation determine according to fixed stars which is controlling the time scale of sidereal time. Many reserachers are concerned about how long the earth takes to spin based on fixed stars since the earth does not actually spin around 360 degrees in one solar day.Furthermore, the computations of the sidereal time needs to take a long time to calculate the number of the Julian centuries. This paper shows a new method of calculating the Sidereal Time, which is very important to determine the stars location at any given time. In addition, this method provdes high accuracy results with short time of calculation. Keywords: Sidereal time; Orbit allocation;Geostationary Orbit;SolarDays;Sidereal Day 1.

It is the angle formed between true north and the projection of the magnetic field vector on the horizontal plane. By convention, declination is measured positive east and negative west (i.e. D -6 means 6 degrees west of north). For surveying practices, magnetic declination is the angle through which a magnetic compass bearing must be rotated in order to point to the true bearing as opposed to the magnetic bearing. Here the true bearing is taken as the angle measured from true North. Declination is reported in units of degrees. One degree is made up of 60 minutes. To convert from decimal degrees to degrees and minutes, multiply the decimal part by 60. For example, 6.5 degrees is equal to 6 degrees and 30 minutes (0.5 x 60 = 30). If west declinations are assumed to be negative while east declination are considered positive then True bearing = Magnetic bearing + Magnetic declination An example: The magnetic bearing of a property line has an azimuth of 72 degrees East.

  • Celestial Coordinate Systems
    Celestial Coordinate Systems Craig Lage Department of Physics, New York University, [email protected] January 6, 2014 1 Introduction This document reviews briefly some of the key ideas that you will need to understand in order to identify and locate objects in the sky. It is intended to serve as a reference document. 2 Angular Basics When we view objects in the sky, distance is difficult to determine, and generally we can only indicate their direction. For this reason, angles are critical in astronomy, and we use angular measures to locate objects and define the distance between objects. Angles are measured in a number of different ways in astronomy, and you need to become familiar with the different notations and comfortable converting between them. A basic angle is shown in Figure 1. θ Figure 1: A basic angle, θ. We review some angle basics. We normally use two primary measures of angles, degrees and radians. In astronomy, we also sometimes use time as a measure of angles, as we will discuss later. A radian is a dimensionless measure equal to the length of the circular arc enclosed by the angle divided by the radius of the circle. A full circle is thus equal to 2π radians. A degree is an arbitrary measure, where a full circle is defined to be equal to 360◦. When using degrees, we also have two different conventions, to divide one degree into decimal degrees, or alternatively to divide it into 60 minutes, each of which is divided into 60 seconds. These are also referred to as minutes of arc or seconds of arc so as not to confuse them with minutes of time and seconds of time.

  • Positional Astronomy Coordinate Systems
    Positional Astronomy Observational Astronomy 2019 Part 2 Prof. S.C. Trager Coordinate systems We need to know where the astronomical objects we want to study are located in order to study them! We need a system (well, many systems!) to describe the positions of astronomical objects. The Celestial Sphere First we need the concept of the celestial sphere. It would be nice if we knew the distance to every object we’re interested in — but we don’t. And it’s actually unnecessary in order to observe them! The Celestial Sphere Instead, we assume that all astronomical sources are infinitely far away and live on the surface of a sphere at infinite distance. This is the celestial sphere. If we define a coordinate system on this sphere, we know where to point! Furthermore, stars (and galaxies) move with respect to each other. The motion normal to the line of sight — i.e., on the celestial sphere — is called proper motion (which we’ll return to shortly) Astronomical coordinate systems A bit of terminology: great circle: a circle on the surface of a sphere intercepting a plane that intersects the origin of the sphere i.e., any circle on the surface of a sphere that divides that sphere into two equal hemispheres Horizon coordinates A natural coordinate system for an Earth- bound observer is the “horizon” or “Alt-Az” coordinate system The great circle of the horizon projected on the celestial sphere is the equator of this system. Horizon coordinates Altitude (or elevation) is the angle from the horizon up to our object — the zenith, the point directly above the observer, is at +90º Horizon coordinates We need another coordinate: define a great circle perpendicular to the equator (horizon) passing through the zenith and, for convenience, due north This line of constant longitude is called a meridian Horizon coordinates The azimuth is the angle measured along the horizon from north towards east to the great circle that intercepts our object (star) and the zenith.
