Leavitt completed her research on period/luminosity by 1912 and astronomers such as Hubble, and Shapley have since used her work. “The period/luminosity law became the yardstick by which distances of stars could be measured by astronomers” (Nix, 1998). Without Leavitt’s work, which went unpraised and mostly unrecognised throughout her life, many of the early advances in astronomy would not have happened. References: Mitchell, Helen Buss. 1976.
It may have been used as an astronomer’s tool or to judge the movement in the heaves. The first builders may have been farmers needing to know when the seasons were about to change. In the middle of the 20th century, a new theory was born – one that suggests that Stonehenge was used as an astronomical calendar. Stonehenge is thought of as a “primitive astronomical computer”. Fred Hoyle believed it was possible to determine eclipses by moving 3 markers around the Aubrey holes in such a way that when all 3 arrived at the same hole an eclipse was about to occur.
* Since Dr. Ride was also well known for her study of Physics she founded her own company called Sally Ride Science. * Serving as president and CEO Dr. Ride founded the company to inspire girls and young women to pursue their interests in science and math. * Dr. Ride was also became the first American woman in space aboard the space shuttle Challenger, her job was to help deploy satellites in space. * After working for NASA, Sally Ride became the director of the California Space Institute in the University of California. * She also was a professor of physics at the school in 1989.
The Maya Civilization and Astronomy The Maya civilization is characterized of being one of the biggest and wisest civilizations of history, who were known of having the only known fully developed written language of pre-Columbian America, and the most advanced Mathematicians and Astronomers. They were mostly characterized for being extraordinary good astronomers who were experts on making observations and recording the motion of the Sun, the Moon, and the stars. Maya’s primary interests were Zenial Passages, when the Sun crossed over Maya latitudes. They were based on an annual basis where the sun travels to its summer solstice at latitude of 23-1/3 degrees north. Since most of the Maya cities were located south, they were able to observe the sun directly overhead while the sun was passing over their latitude.
III. Most importantly, I will discuss: A. The history of Astrology B. The influence of each planet on your personality C. How to interpret each planet in relation to your signs D. How to do an astrological birth chart Body I. According to The History of Astrology from Gryphon Astrology.com, The oldest undisputed evidence of the use of astrology as system of knowledge was recorded in the first dynasty of Mesopotamia (1950-1651 BC), giving astrology a 4,000 year history as a body of organized logic used in civilization.
The Mayan Haab Calendar. Done by Selma Chavaria The Mayan Haab Calendar The Maya were among the most innovative astronomers of their time. They used monuments, buildings and wooden implements to observe celestial bodies. Evidence confirmed that they have found ways to capture the passage of the sun, moon, and Venus. They observed and predicted lunar eclipses and created the length of a tropical year as 365.2420 days.
Also, she argues that Most of the light is X-rays, but a tail of emission extends to longer, ultraviolet and optical wavelengths. Other example provided by the author is the Galaxy Evolution Explorer known as GALEX. This is a telescope launched in 2003, observes ultraviolet radiation, but according with Gezari the use of the GALEX to search among galaxies and find tidal disruption was a good idea because the astronomers found the three luminous ultraviolet flares coming from normal-looking galaxies. The author proves that the three flares came from gas glowing at
to make possible records of trade and property. Writing also had a religious function of granting scribes power over the natural world. Around 2000 B.C.E., the Sumerians recorded the oldest literary epic, the story of Gilgamesh. Sumerian sculpture and painting were used to decorate religious precincts. The Sumerians were particularly advanced mathematicians who used their calculations to help understand the movement of the sun and stars.
Today, we know that stars are born from interstellar gas clouds, shine by nuclear fusion and then die, sometimes in dramatic ways. This paper will discuss the life cycle of stars, but to have a better understanding of the life cycle of stars we first need to understand their birth. Since we were children, we have been curious about those little lights in the night sky that seem to twinkle in the darkness. We even sang about them growing up, “Twinkle, twinkle, little star, how I wonder what you are? As a child, we could not understand the magnificent miracle that takes place for a star to be born.
The goal of education in ancient Greece was to produce citizens trained in the arts of both peace and war (http://www.crystalinks.com). The scientific and mathematical discoveries of Ancient Greece altered the way that we will view the world forever. Astronomers at the time made sense of the sky, and our status in the universe (http://members.tripod.com). Astronomy is the study of the stars, planets, and other objects that make up our universe, and in Ancient Greece the information that was discovered was highly developed and researched. Greek astronomers knew a lot of the geometrical relationships of heavenly bodies, or stars.
