Throughout human existence, one of the most prominent inventions ever has to be the act of recording time, or timekeeping. Ever since the most primitive eras of civilization mankind has found ways to measure the passage of time from studying celestial bodies, the sun, moon, planets, and stars. Beginning with timepieces that run on daylight, such as the sundial, developing into digital clocks we use today, it can even be argued that timekeeping is even a basic necessity in today’s society.
As long ago as 20,000 years ago ice-age hunters from Europe would take sticks and bones and scratch lines and mark holes in them, supposedly counting the days between phased of the moon. 5,000 years ago, the Sumerians that had occupied present-day Iraq divided the year into 30-day months, the also divided the day into 12 periods (equivalent to 2 of our hours), and divided those into 30 parts (equivalent to 4 of our minutes).
Although, the first Egyptian calendar was based in moon cycles, they noticed that every 365 days the “Dog Star” in Canis Major, now referred to as Sirius rose next to the su...
Ancient Pueblo Indians had a great understanding of astronomy. All of the pueblos in the canyon were aligned to match the movements of the sun and moon. Also, they marked their complexes with daggers and spirals to keep up with the moon cycles and sun movements. The film explains that the moon moves north for nearly ten years and then south for about ten years. To fully understand this cycle of the moon, Pueblo people had to study it for years in order to build their Pueblos in relations to it. The sun however, was different because it set and rose in the same position. The concept of building structures in an astronomical pattern this complex cannot be found anywhere else.
This book focuses on different types of calendars from a number of different places all around the world. This specific chapter, even more specifically this section, focuses on the Mayan calendar. These calendars were written by honored members of their aristocracy and were held to be of great value. The Spanish invaders believed them to be instruments of the devil and burnt great quantities of them. E. G. Richards explains that only four Mayan books are survive in the libraries of Europe, and one of those—The Dresden codex—suffered severe damage in another fire, one which was inflicted on that city in the Second World War. Richards says that the earliest record of a calendar survives from about 500 BC in Monte Alban near Oaxaca. This calendar employs a 260-day cycle, which was commonly used by several societies and is still in use among the present-day inhabitants of the region. The Maya used the calendar partly to anticipate propitious days to embark on wars and other activities. It was also used to record on stone pillars, or stelae, important events in the lives of their kings and to relate these to more mythical events of the past. The Mayan calendar system involved two major methods of specifying a specific date—the calendar round and the long count. The calendar round was used to specify a date within a period of about 52 years, while the long count served to relate such dates within a longer period named a great cycle. The calendar round involved three interlocking cycles of 13, 20, and 365 days respectively. The 365-day cycle was called a haab and was similar to the Egyptian wandering year. Each haab was divided into 18 periods called uinals; each uinal had 20 days and a name. The 18 uinal were followed by five epagomen...
Throughout the day we are constantly checking the time, preparing for the upcoming months, and keeping track of the year. Clocks tell us the time we use as a measurement. It’s how we keep track of those important months and events, such as holidays and birthdays. Although there are many investigations and research being done on the nature of time, many unresolved issues remain.
...eir records by building structures that would observe the sun. the Bighorn Medicine Wheel in Wyoming dates to AD 1400 to 1700. Lines drawn between major markings on the wheel point to the location of solstice sunrises and sunsets and also toward the rising point of the three brightest stars that rise before the sun in the summer. About fifty medicine wheels have been discovered, several are thousands of years. Many of them have the same alignment as the Bighorn Medicine Wheel. In Chaco Canyon, New Mexico two spirals carved into the rock by the prehistoric Anasazi can be used as a calendar. A dagger of light penetrates the shadow of adjacent rocks. The dagger moves with the sun to different locations on the spiral.the full pattern also reflects the 18.6 year cycle of the moon as well as the yearly cycle of the sun. The ancient Native Americans were not sophisticated astronomers in the sense of coherent theory behind the movements of heavenly objects, their level of understanding of the time cycles of the sun, moon and planets was great. The methods for recording and keeping track of the seasonal movements was clever and displays a cultural richness that varies from tribe to tribe.
John McTaggart in his essay “Time” presents a radical argument that claims time is unreal. While the argument is interesting and has attracted much attention for his arguments, I remain unconvinced of the argument he makes. This paper will lay out McTaggart’s argument that time in unreal, critically analyze why I believe McTaggart’s argument fails and present an alternative idea about time, utilizing aspects of McTaggart’s argument.
Fractions have been a around long enough for me to understand that I do not like them, but they play a significant part in simplifying, for some, division of goods or time. There is no one person who can be credited with the invention of fractions, but their use has been traced back as early as 1000 BC, in Egypt--using the formula to trade tangibles, currency, and build pyramids.
Time is life. It is irreversible and irreplaceable. To waste one’s time is to waste one’s life, but mastery of time usage is mastery of life and making the most of it. Einstein once said, “There is no absolute relation in time between two events, but there is an absolute relation between space and time” (Sharp 1). Time is a mystery. It cannot be tied down by definition or confined inside a formula. Like gravity, it is a phenomenon that we can experience but cannot understand. We are aware of the ageing of our bodies, of the effects of the movements of our planet, and of the ticking of the clock. We learn a little about what we call the past and we know that change is built into our lives. But neither philosophers nor scientists have been able to analyze and explain all of the meaning of time. Not only have they failed to provide easy explanations, but their efforts sometimes seem to have made mystery more mysterious and to have shown us that our lack of understanding was even greater than we supposed.
People check the time throughout the day, every day, making time essential to lives. The intrinsic importance of time is twofold: biologically people have an internal clock to regulate the most basic behaviors like breathing, sleeping, and blinking, and socially, time regulates daily lives like communication, farming, and business keeping. In fact, Eviatar Zerubavel, a professor of sociology at Rutgers University, argues that standard time is one of the “most essential” elements of the “social world”; social life is made possible with the ability to relate time (Zerubavel 2). Therefore, any change in the perception of time marks modification in thinking or an alteration to the social fabric. Throughout history perceived time has changed: sundials
The focal point will be on the textual sources, for the most part the Cairo Calendar, since it reveals portions of the mythology linked to the epagomenal days; as well as supernatural Ancient Egyptian texts, such as The Book of the Last Day of the Year, which will help with supporting the examination of the fear ascribed to these final days of the year, along with determining whether the Egyptians were truly terrified by the epagomenal days themselves, or if they were fearful of the disease and plague that commonly persisted during that time of the year. This paper will present that the Ancient Egyptians, having been driven by their need for order, Ma’at, to succeed over chaos, Isfet, used myths of mystical causation for the purpose of providing themselves a rational and sound reason of the chaos and hostility that occurs during the last five days of the year to insert into their perspective; and instead of being apprehensive of the epagomenal days alone, the Egyptian were terrified of the recurring threat of plague and disease that was common during that time of the
Many inventors have left their mark on society. One inventor, in particular, is commonly found at the top of the list of the greatest inventors in world history. He has influenced and impacted many facets of our lives. His inventions laid the foundation of many industries and products which still exist today.

Due to archeological evidence we know that the African people were the first people in the world to use counting to keep track of their things, or time. Around 35,000 BC, in South Africa the earliest known tally stick was made, and was left in Lebombo Cave. 29 notches were cut into the stick. We don't know exactly what they were counting. Some people think they were counting the days from one moon phase to the next, but it could have been something else. Just as well. Now, what we do see is that by 35,000 BC people in South Africa had the idea of keeping records by making marks. “The Lebombo bone is a baboon fibula with a set of 29 notches carved in it. Archeologists believe these marks are evidence of a primitive calendar, measuring either the lunar or the menstrual calendar. This artifact is incredibly important for unders...
One cultural group was especially important for their discoveries in astronomy, the Egyptians. They were especially important because they were one of the first groups of people to create an accurate calendar. This calendar was different than others because it was based off of the Sun and stars rather than the moon. The calendars purpose was to make correct estimates of when to plan...
Astronomy is a natural science focusing on the study of celestial objects such as moons, stars, planets, nebulae and galaxies. Astronomy is considered to be one of the oldest natural sciences; early civilizations throughout history such as the Babylonians, Egyptians and Greeks performed methodical observations of the sky. The Babylonians had different astronomical records regarding the position of the moon, sun and stars, on the other hand the Egyptians used astronomy to know the time and afterwards they developed a calendar based on the solar year. The following paper will focus on the ancient Greek astronomy, interestingly the origin of the word astronomy is Greek it comes from two words; astron meaning "star" and nemien refers to "to name". This paper will explain and highlight the methods used, famous figures and the achievements attained during the ancient Greek astronomy era.
Timekeeping has been an integral part of life ever since humans stepped foot on the earth. Once humans realized the difference between night and day, moon phases were used to determine months, changing seasons and record years. Soon humans realized the connection of time with the sun’s position and started using shadows to keep time thus creating the sundial, used foremost by the Egyptians and Greeks. As life become more complex, so did the need to keep time accurately. Initially, the mechanical clock was invented in 1000 AD. We then graduated to using celestial time and finally the atomic clocks were invented in 1967. These atomic clocks are so efficient that they make other methods of timekeeping seem redundant. Thus we have come a long way in timekeeping and I strongly believe that continuing to use the earth’s rotation around the sun as a method of timekeeping would mean ignoring the advances made in timekeeping over the course of history and moving further back into the past.
