  • Earth-Moon-Sun-System EQUINOX Presentation V2.Pdf
    The Sun http://c.tadst.com/gfx/750x500/sunrise.jpg?1 The sun dominates activity on Earth: living and non­living. It'd be hard to imagine a day without it. The daily pattern of the sun rising in the East and setting in the West is how we measure time...marking off the days of our lives. 6 The Sun http://c.tadst.com/gfx/750x500/sunrise.jpg?1 Virtually all life on Earth is aware of, and responds to, the sun's movements. Well before there was written history, humankind had studied those patterns. 7 Daily Patterns of the Sun • The sun rises in the east and sets in the west. • The time between sunrises is always the same: that amount of time is called a "day," which we divide into 24 hours. Note: The term "day" can be confusing since it is used in two ways: • The time between sunrises (always 24 hours). • To contrast "day" to "night," in which case day means the time during which there is daylight (varies in length). For instance, when we refer to the summer solstice as being the longest day of the year, we mean that it has the most daylight hours of any day. 8 Explaining the Sun What would be the simplest explanation of these two patterns? • The sun rises in the east and sets in the west. • The time between sunrises is always the same: that amount of time is called a "day." We now divide the day into 24 hours. Discuss some ideas to explain these patterns.

  • The Application of Precision Measurement in Historic Building
    The Application of Precision Measurement in Historic Building Conservation: Taking Guanxing Tai, a historic Chinese Observatory, as an Example Xiao Jinliang 1 1Beijing Tsinghua Urban Planning & Design Institute, Department of Architecture & Urban Heritage Beijing, P. R. China [email protected] Keywords : Guanxing Tai, Precision Measurement, Total Station, Historic Building Conservation Abstract: Guanxing Tai, the ancient Observatory in central China, built in the 13th century as a national facility for astronomical observations, served the dual purposes of an astronomical building and an astronomical instrument as well. For a long time, many historians and astronomers attribute the Observatory’s somewhat peculiar design to special astronomical numeric values like the solar elevation angle. Besides, the askew brick joints in this old brick-made building make heritage conservation experts doubt the stability of its foundations. By means of total station survey system, close-range photogrammetry and geophysical survey, we have collected precise information about its exterior and inner structure, and gradually unraveled the mysteries about the ancient building through GIS analysis and computer simulation. Our tests rule out the connection between its design and astronomical numeric values, enable us to propose a new view, i.e. the peculiar architectural style may be the result of ancient craftsmen’s unconscious brick-laying acts in two directions, and invalidate the conclusion of the seemingly unstable foundations. Our new findings also provide us with more clues as to the brick processing techniques in ancient China. 1. Overview, History and Value The Guanxing Tai Observatory is the earliest one of its kind so far extant in China, and is also one of the earliest buildings for astronomical observation in the world.

  • PRIME MERIDIAN a Place Is
    Lines of Latitude and Longitude help us to answer a key geographical question: “Where am I?” What are Lines of Latitude and Longitude? Lines of Latitude and Longitude refer to the grid system of imaginary lines you will find on a map or globe. PARALLELS of Latitude and MERIDIANS of Longitude form an invisible grid over the earth’s surface and assist in pinpointing any location on Earth with great accuracy; everywhere has its own unique grid location, and this is expressed in terms of LATITUDE and LONGITUDE COORDINATES. Lines of LATITUDE are the ‘horizontal’ lines. They tell us whether a place is located in the NORTHERN or the SOUTHERN HEMISPHERE as well as how far North or South from the EQUATOR it is. Lines of LONGITUDE are the ‘vertical’ lines. They indicate how far East or West of the PRIME MERIDIAN a place is. • The EQUATOR is the 0° LATITUDE LINE. o North of the EQUATOR is the NORTHERN HEMISPHERE. o South of the EQUATOR is the SOUTHERN HEMISPHERE. • Lines of Latitude cross the PRIME MERIDIAN (longitude line) at right angles (90°). • Lines of Latitude circle the globe/world in an east- west direction. • Lines of Latitude are also known as PARALLELS. o As they are parallel to the Equator and apart always at the same distance. • Lines of Latitude measure distance north or south from the equator i.e. how far north or south a point lies from the Equator. • The distance between degree lines is about 69 miles (or about 110km). o A DEGREE (°) equals 60 minutes - 60’.

  • Summer Solstice Summer Solstice June 20, 2021 9:32 PM
    Weather Forecast Office Summer Solstice Albuquerque, NM 2021 Updated: June 16, 2021 10:43 PM MDT Summer Solstice June 20, 2021 9:32 PM MDT The Northern Hemisphere summer solstice will occur at 9:32 pm MDT on June 20, 2021. This date marks the official beginning of summer in the Northern Hemisphere, occurring when Earth arrives at the point in its orbit where the North Pole is at its maximum tilt (about 23.5 degrees) toward the Sun, resulting in the longest day and shortest night of the calendar year. (By longest “day,” we mean the longest period of sunlight hours.) On the day of the June solstice, the Northern Hemisphere receives sunlight at the most direct angle of the year (see the images below). nasa.gov NWS Albuquerque weather.gov/abq Weather Forecast Office Summer Solstice Albuquerque, NM The Seasons Updated: June 16, 2021 10:43 PM MDT We all know that the Earth makes a complete revolution nasa.gov around the sun once every 365 days, following an orbit that is elliptical in shape. This means that the distance between the Earth and Sun, which is 93 million miles on average, varies throughout the year. The top figure on the right illustrates that during the first week in January, the Earth is about 1.6 million miles closer to the sun. This is referred to as the perihelion. The aphelion, or the point at which the Earth is about 1.6 million miles farther away from the sun, occurs during the first week in July. This fact may sound counter to what we know about seasons in the Northern Hemisphere, but actually the difference is not significant in terms of climate and is NOT the reason why we have seasons.

At the slab revealed two interrelated groups of wells, one of which - in the form of a circle, is proposed to interpret how analemmatic sundial, and second group, consisting of disparate wells, as auxiliary astronomical markers of rising luminaries directions, to correct the position of the gnomon. Simultaneous location of both groups of wells on the same slab is a possible indication of one of the stages of development of the design features analemmatic sundial - setting movable gnomon and technology of measuring time with it. It may point to local origin, as the very idea of analemmatic sundial as well technology measurement of time with them. The article also describes the model analemmatic sundial, hour marks which in many cases coincide with the wells arranged in a circle, particularly in a working range from 6 to 18 hours. In the study proposed a method which can identify moments of solstices and equinoxes in ancient times with the help of the gnomon of analemmatic sundial and mobile gnomons, installed in wells belonging to the second group.

  • “The Story of the Seasons”
    “The Story of the Seasons” The Earth takes 365 and 1/4 days to complete one revolution around the sun and this amount of time is called a “year.” Every four years, 1/4 of a day will add up to 24- hour day, and we add an extra day (February 29th) to the calendar. This is why we have a “leap year” with one extra day every four years. The Earth’s orbit is nearly circular (or slightly elliptical) and Earth is actually closer to the sun during the northern hemisphere’s winter months. Summer On the first day of summer, June 20 or 21st, the Earth’s Northern Hemisphere is tilted 23.5° toward the sun. The day is known as the summer solstice. On this day the sun is at its highest point in the Northern Hemisphere sky at noon and directly over the Tropic of Cancer (the 23.5°N parallel of latitude). Solstice means “sun stop” in Latin. When the Northern Hemisphere is tilted toward the sun, that part of the Earth receives more direct rays of sunlight during the daytime than the Southern Hemisphere does. The Southern Hemisphere is tilted away from the sun and therefore, receives the sun’s rays at an angle. As a result, it is summer in the Northern Hemisphere and winter in the Southern Hemisphere. Conversely, during our winter months when the Northern Hemisphere is tilted away from the sun, it is summer in the Southern Hemisphere. During the summer, the land, oceans, and atmosphere in the Northern Hemisphere receive more direct rays of sunlight.
