AST 443 / PHY 517 Astronomical Observing Techniques Prof. F.M. Walter I. The Basics The 3 basic measurements: • WHERE something is • WHEN something happened • HOW BRIGHT something is Since this is science, let’s be quantitative! Where • Positions: – 2-dimensional projections on celestial sphere (q,f) • q,f are angular measures: radians, or degrees, minutes, arcsec – 3-dimensional position in space (x,y,z) or (q, f, r). • (x,y,z) are linear positions within a right-handed rectilinear coordinate system. • R is a distance (spherical coordinates) • Galactic positions are sometimes presented in cylindrical coordinates, of galactocentric radius, height above the galactic plane, and azimuth. Angles There are • 360 degrees (o) in a circle • 60 minutes of arc (‘) in a degree (arcmin) • 60 seconds of arc (“) in an arcmin There are • 24 hours (h) along the equator • 60 minutes of time (m) per hour • 60 seconds of time (s) per minute • 1 second of time = 15”/cos(latitude) Coordinate Systems "What good are Mercator's North Poles and Equators Tropics, Zones, and Meridian Lines?"

Geological Timeline
Geological Timeline In this pack you will find information and activities to help your class grasp the concept of geological time, just how old our planet is, and just how young we, as a species, are. Planet Earth is 4,600 million years old. We all know this is very old indeed, but big numbers like this are always difficult to get your head around. The activities in this pack will help your class to make visual representations of the age of the Earth to help them get to grips with the timescales involved. Important EvEnts In thE Earth’s hIstory 4600 mya (million years ago) – Planet Earth formed. Dust left over from the birth of the sun clumped together to form planet Earth. The other planets in our solar system were also formed in this way at about the same time. 4500 mya – Earth’s core and crust formed. Dense metals sank to the centre of the Earth and formed the core, while the outside layer cooled and solidified to form the Earth’s crust. 4400 mya – The Earth’s first oceans formed. Water vapour was released into the Earth’s atmosphere by volcanism. It then cooled, fell back down as rain, and formed the Earth’s first oceans. Some water may also have been brought to Earth by comets and asteroids. 3850 mya – The first life appeared on Earth. It was very simple single-celled organisms. Exactly how life first arose is a mystery. 1500 mya – Oxygen began to accumulate in the Earth’s atmosphere. Oxygen is made by cyanobacteria (blue-green algae) as a product of photosynthesis. -

Understanding of Reverse Perspective in Old Russian Iconography Examining Committee: Chair: Gary McCarron Associate Professor, Dept. of Communication Graduate Chair, Graduate Liberal Studies Program Jerry Zaslove Senior Supervisor Professor Emeritus Humanities and English Heesoon Bai Supervisor Professor Faculty of Education Paul Crowe External Examiner Associate Professor Humanities and Asia-Canada Program Date Defended/Approved: November 25, 2015 ii Abstract The first essay is a sustained reflection on and response to the question of why the notion of collectivism and collective coexistence has been so deeply entrenched in the Russian society and in the Russian psyche and is still pervasive in today's Russia, a quarter of a century after the fall of communism. It examines the development of ideas of collectivism and individualism in Russian society, focusing on the cultural aspects based on the examples of selected works from Russian literature. It also searches for the answers in the philosophical works of Vladimir Solovyov, Nicolas Berdyaev and Vladimir Lossky. -

Ovid, Fasti 1.63-294 (Translated By, and Adapted Notes From, A
Ovid, Fasti 1.63-294 (translated by, and adapted notes from, A. S. Kline) [Latin text; 8 CE] Book I: January 1: Kalends See how Janus1 appears first in my song To announce a happy year for you, Germanicus.2 Two-headed Janus, source of the silently gliding year, The only god who is able to see behind him, Be favourable to the leaders, whose labours win Peace for the fertile earth, peace for the seas: Be favourable to the senate and Roman people, And with a nod unbar the shining temples. A prosperous day dawns: favour our thoughts and speech! Let auspicious words be said on this auspicious day. Let our ears be free of lawsuits then, and banish Mad disputes now: you, malicious tongues, cease wagging! See how the air shines with fragrant fire, And Cilician3 grains crackle on lit hearths! The flame beats brightly on the temple’s gold, And spreads a flickering light on the shrine’s roof. Spotless garments make their way to Tarpeian Heights,4 And the crowd wear the colours of the festival: Now the new rods and axes lead, new purple glows, And the distinctive ivory chair feels fresh weight. Heifers that grazed the grass on Faliscan plains,5 Unbroken to the yoke, bow their necks to the axe. When Jupiter watches the whole world from his hill, Everything that he sees belongs to Rome. Hail, day of joy, and return forever, happier still, Worthy to be cherished by a race that rules the world. But two-formed Janus what god shall I say you are, Since Greece has no divinity to compare with you? Tell me the reason, too, why you alone of all the gods Look both at what’s behind you and what’s in front. -

It is used (often alongside the Gregorian calendar) to date events in many Muslim countries. It is also used by Muslims to determine the proper days of Islamic holidays and rituals, such as the annual period of fasting and the proper time for the pilgrimage to Mecca. The Islamic calendar employs the Hijri era whose epoch was Islamic Calendar stamp issued at King retrospectively established as the Islamic New Year of AD 622. During Khaled airport (10 Rajab 1428 / 24 July that year, Muhammad and his followers migrated from Mecca to 2007) Yathrib (now Medina) and established the first Muslim community (ummah), an event commemorated as the Hijra. In the West, dates in this era are usually denoted AH (Latin: Anno Hegirae, "in the year of the Hijra") in parallel with the Christian (AD) and Jewish eras (AM). In Muslim countries, it is also sometimes denoted as H[1] from its Arabic form ( [In English, years prior to the Hijra are reckoned as BH ("Before the Hijra").[2 .(ﻫـ abbreviated , َﺳﻨﺔ ﻫِ ْﺠﺮﻳّﺔ The current Islamic year is 1438 AH.

The 100 Years Anglo-Chinese Calendar, 1St Jan. 1776 to 25Th Jan
: THE 100 YEARS ANGLO-CHINESE CALENDAR, 1st JAN., 1776 to 25th JAN., 187G, CORRESPONDING WITH THE 11th DAY of the 11th MOON of the 40th YEAR of the EEIGN KIEN-LUNG, To the END of the 14th YEAR of the REIGN TUNG-CHI; TOGETIIER WITH AN APPENDIX, CONTAINING SEVERAL INTERESTING TABLES AND EXTRACTS. BY IP. LOUE;EIE,0. SHANGHAI rRINTED AT THE " NORTH-CHINA HERALD " OFFICE, 1872. -A c^ V lo ; ; PREFACE. In presenting the 100 Years Anglo-Chinese Calendar to the public, the compiler claims no originality for his work, inasmuch as, since the year 1832,* Calendars in somewhat similar form have been yearly issued from the press in China ; but, as it is doubtful if a complete series of these exists, and as, in the transaction of business, whether official, legal or commercial, between Foreigners and Chinese, and in the study of Chinese History which is now so intimately connected with foreign nations, a knowledge of the corresponding dates is quite necessary, it is hoped that this compilation will be found useful, and especially so in referring to the date of past events, and in deciding the precise day, according to the Chinese and Chris- tian Calendars, on which they occurred. Commencing with the last quarter of the past century (1st January, 1776), the Calendar embraces the peiiod when the first British Embassy (Lord Macartney's in 1793) arrived in China. For convenience sake the Calendar has been divided into 10 parts, each embracing a period of ten years of the Christian era and ends with the close of the 14th year of the present reign Tung-chi, —the 25th January, 1876. -

TABLE OF CONTENTS OODROW WILSON at Princeton, John Calhoun at Yale, Jefferson Davis at the University of Texas at Austin: Students, campus officials, and historians are all asking the question, What’sW in a name? And what is a university’s responsibil- ity when the name on a statue, building, or program on campus is a painful reminder of harm to a specific racial group? Universities have been grappling anew with those questions, and trying different approaches to resolve them.

Calculating Percentages for Time Spent During Day, Week, Month
Calculating Percentages of Time Spent on Job Responsibilities Instructions for calculating time spent during day, week, month and year This is designed to help you calculate percentages of time that you perform various duties/tasks. The figures in the following tables are based on a standard 40 hour work week, 174 hour work month, and 2088 hour work year. If a recurring duty is performed weekly and takes the same amount of time each week, the percentage of the job that this duty represents may be calculated by dividing the number of hours spent on the duty by 40. For example, a two-hour daily duty represents the following percentage of the job: 2 hours x 5 days/week = 10 total weekly hours 10 hours / 40 hours in the week = .25 = 25% of the job. If a duty is not performed every week, it might be more accurate to estimate the percentage by considering the amount of time spent on the duty each month. For example, a monthly report that takes 4 hours to complete represents the following percentage of the job: 4/174 = .023 = 2.3%. Some duties are performed only certain times of the year. For example, budget planning for the coming fiscal year may take a week and a half (60 hours) and is a major task, but this work is performed one time a year. To calculate the percentage for this type of duty, estimate the total number of hours spent during the year and divide by 2088. This budget planning represents the following percentage of the job: 60/2088 = .0287 = 2.87%. -

How Long Is a Year.Pdf
How Long Is A Year? Dr. Bryan Mendez Space Sciences Laboratory UC Berkeley Keeping Time The basic unit of time is a Day. Different starting points: • Sunrise, • Noon, • Sunset, • Midnight tied to the Sun’s motion. Universal Time uses midnight as the starting point of a day. Length: sunrise to sunrise, sunset to sunset? Day Noon to noon – The seasonal motion of the Sun changes its rise and set times, so sunrise to sunrise would be a variable measure. Noon to noon is far more constant. Noon: time of the Sun’s transit of the meridian Stellarium View and measure a day Day Aday is caused by Earth’s motion: spinning on an axis and orbiting around the Sun. Earth’s spin is very regular (daily variations on the order of a few milliseconds, due to internal rearrangement of Earth’s mass and external gravitational forces primarily from the Moon and Sun). Synodic Day Noon to noon = synodic or solar day (point 1 to 3). This is not the time for one complete spin of Earth (1 to 2). Because Earth also orbits at the same time as it is spinning, it takes a little extra time for the Sun to come back to noon after one complete spin. Because the orbit is elliptical, when Earth is closest to the Sun it is moving faster, and it takes longer to bring the Sun back around to noon. When Earth is farther it moves slower and it takes less time to rotate the Sun back to noon. Mean Solar Day is an average of the amount time it takes to go from noon to noon throughout an orbit = 24 Hours Real solar day varies by up to 30 seconds depending on the time of year.
