“The Hourglass”
Grand Lodge of Wisconsin – Masonic Study Series Volume 2, issue 5 November 2016 “The Hourglass” Lodge Presentation: The following short article is written with the intention to be read within an open Lodge, or in fellowship, to all the members in attendance. This article is appropriate to be presented to all Master Masons . Master Masons should be invited to attend the meeting where this is presented. Following this article is a list of discussion questions which should be presented following the presentation of the article. The Hourglass “Dost thou love life? Then squander not time, for that is the stuff that life is made of.” – Ben Franklin “The hourglass is an emblem of human life. Behold! How swiftly the sands run, and how rapidly our lives are drawing to a close.” The hourglass works on the same principle as the clepsydra, or “water clock”, which has been around since 1500 AD. There are the two vessels, and in the case of the clepsydra, there was a certain amount of water that flowed at a specific rate from the top to bottom. According to the Guiness book of records, the first hourglass, or sand clock, is said to have been invented by a French monk called Liutprand in the 8th century AD. Water clocks and pendulum clocks couldn’t be used on ships because they needed to be steady to work accurately. Sand clocks, or “hour glasses” could be suspended from a rope or string and would not be as affected by the moving ship. For this reason, “sand clocks” were in fairly high demand in the shipping industry back in the day. -
Daylight Saving Time (DST)
Daylight Saving Time (DST) Updated September 30, 2020 Congressional Research Service https://crsreports.congress.gov R45208 Daylight Saving Time (DST) Summary Daylight Saving Time (DST) is a period of the year between spring and fall when clocks in most parts of the United States are set one hour ahead of standard time. DST begins on the second Sunday in March and ends on the first Sunday in November. The beginning and ending dates are set in statute. Congressional interest in the potential benefits and costs of DST has resulted in changes to DST observance since it was first adopted in the United States in 1918. The United States established standard time zones and DST through the Calder Act, also known as the Standard Time Act of 1918. The issue of consistency in time observance was further clarified by the Uniform Time Act of 1966. These laws as amended allow a state to exempt itself—or parts of the state that lie within a different time zone—from DST observance. These laws as amended also authorize the Department of Transportation (DOT) to regulate standard time zone boundaries and DST. The time period for DST was changed most recently in the Energy Policy Act of 2005 (EPACT 2005; P.L. 109-58). Congress has required several agencies to study the effects of changes in DST observance. In 1974, DOT reported that the potential benefits to energy conservation, traffic safety, and reductions in violent crime were minimal. In 2008, the Department of Energy assessed the effects to national energy consumption of extending DST as changed in EPACT 2005 and found a reduction in total primary energy consumption of 0.02%. -
The International Date Line!
The International Date Line! The International Date Line (IDL) is a generally north-south imaginary line on the surface of the Earth, passing through the middle of the Pacific Ocean, that designates the place where each calendar day begins. It is roughly along 180° longitude, opposite the Prime Meridian, but it is drawn with diversions to pass around some territories and island groups. Crossing the IDL travelling east results in a day or 24 hours being subtracted, so that the traveller repeats the date to the west of the line. Crossing west results in a day being added, that is, the date is the eastern side date plus one calendar day. The line is necessary in order to have a fixed, albeit arbitrary, boundary on the globe where the calendar date advances. Geography For part of its length, the International Date Line follows the meridian of 180° longitude, roughly down the middle of the Pacific Ocean. To avoid crossing nations internally, however, the line deviates to pass around the far east of Russia and various island groups in the Pacific. In the north, the date line swings to the east of Wrangel island and the Chukchi Peninsula and through the Bering Strait passing between the Diomede Islands at a distance of 1.5 km (1 mi) from each island. It then goes southwest, passing west of St. Lawrence Island and St. Matthew Island, until it passes midway between the United States' Aleutian Islands and Russia's Commander Islands before returning southeast to 180°. This keeps Russia which is north and west of the Bering Sea and the United States' Alaska which is east and south of the Bering Sea, on opposite sides of the line in agreement with the date in the rest of those countries. -

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%. -

Encyclopedic Entry prime meridian For the complete encyclopedic entry with media resources, visit: http://education.nationalgeographic.com/encyclopedia/prime-meridian/ The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. Any line of longitude (a meridian) can serve as the 0 longitude line. However, there is an international agreement that the meridian that runs through Greenwich, England, is considered the official prime meridian. Governments did not always agree that the Greenwich meridian was the prime meridian, making navigation over long distances very difficult. Different countries published maps and charts with longitude based on the meridian passing through their capital city. France would publish maps with 0 longitude running through Paris. Cartographers in China would publish maps with 0 longitude running through Beijing. Even different parts of the same country published materials based on local meridians. Finally, at an international convention called by U.S. President Chester Arthur in 1884, representatives from 25 countries agreed to pick a single, standard meridian. They chose the meridian passing through the Royal Observatory in Greenwich, England. The Greenwich Meridian became the international standard for the prime meridian. UTC The prime meridian also sets Coordinated Universal Time (UTC). UTC never changes for daylight savings or anything else. Just as the prime meridian is the standard for longitude, UTC is the standard for time. -
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. Introduction (the upper meridian) in the sky[6]. Solar time is what the time we all use where a day is defined as 24 hours, which is The word "sidereal" comes from the Latin word sider, the average time that it takes for the sun to return to its meaning star. -
Sidereal Time 1 Sidereal Time
Sidereal time 1 Sidereal time Sidereal time (pronounced /saɪˈdɪəri.əl/) is a time-keeping system astronomers use to keep track of the direction to point their telescopes to view a given star in the night sky. Just as the Sun and Moon appear to rise in the east and set in the west, so do the stars. A sidereal day is approximately 23 hours, 56 minutes, 4.091 seconds (23.93447 hours or 0.99726957 SI days), corresponding to the time it takes for the Earth to complete one rotation relative to the vernal equinox. The vernal equinox itself precesses very slowly in a westward direction relative to the fixed stars, completing one revolution every 26,000 years approximately. As a consequence, the misnamed sidereal day, as "sidereal" is derived from the Latin sidus meaning "star", is some 0.008 seconds shorter than the earth's period of rotation relative to the fixed stars. The longer true sidereal period is called a stellar day by the International Earth Rotation and Reference Systems Service (IERS). It is also referred to as the sidereal period of rotation. The direction from the Earth to the Sun is constantly changing (because the Earth revolves around the Sun over the course of a year), but the directions from the Earth to the distant stars do not change nearly as much. Therefore the cycle of the apparent motion of the stars around the Earth has a period that is not quite the same as the 24-hour average length of the solar day. Maps of the stars in the night sky usually make use of declination and right ascension as coordinates. -

The Quantum Hourglass
The Quantum Hourglass Approaching time measurement with Quantum Information Theory Paul Erker Master Thesis, ETH Z¨urich September 30, 2014 Abstract In this thesis a general non-relativistic operational model for quan- tum clocks called quantum hourglass is devised. Taking results from the field of Quantum Information Theory the limitations of such time measurement devices are explored in different physical and information- theoretic scenarios. It will be shown for certain cases that the time resolution of the quantum hourglass is limited by its power consump- tion.

Akimasa Miyake [1] Time enters Quantum Theory in manifold ways. Since the early days of quantum theory this led to heated discussions about its nature. In a letter Heisenberg wrote to Pauli in November 1925, he commented: Your problem of the time sequence plays, of course, a fundamen- tal role, and I had figured out for my own private use (Hausge- brauch) something about it. -

Latitude Lines and Longitude Lines Longitude Lines • Longitude Lines run from the North to the South pole and are equal in length. They tell you where you are East and West of the Prime Meridian (runs through Greenwich, England). 0o longitude 30o East longitude 30o West longitude Longitude Lines • Looking at the Earth from above the North Pole, you can see the Prime Meridian and the International Date Line. 0o Prime Meridian 90o East 90o West 180o International Date Line International Date Line • The International Date Line sits on the 180º line of longitude in the middle of the Pacific Ocean. It is the imaginary line that separates two consecutive calendar days. - It is not a perfectly straight line and has been moved slightly over the years to accommodate needs of varied countries in the Pacific Ocean. International Date Line • Immediately to the left of the International Date Line (the date) is always one day ahead of the date (or day) immediately to the right of the International Date Line in the Western Hemisphere. So, travelling east across the International Date Line results in a day, or 24 hours being subtracted. Travelling west across the International Date Line results in a day being added. International Date Line and the Prime Meridian Not a Straight Line! Latitude Lines • Latitude lines run from East to West and tell you where you are North and South of the Equator.
