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. The ancient method of using the earth’s rotation around the sun as a method of keeping time requires one to add leap seconds to the time determined by atomic clocks in order to keep it coordinated with celestial time. This is because the earth has been slowing down over the years due to friction between ocean tides and the shallow sea floors caused by the gravitational pull of the moon. This moon causes the earth’s spin to slow down as much as 1.4 milliseconds or longer. In addition to this, irregular rotations of the earth occur because the molten core and the solid mantle of earth rotate at different rates. These esoteric motions make timekeeping very unreliable and cause the Earth day to be longer than that measured by atomic clocks and the length of... ... middle of paper ... ...t on their operation. In some cases, the need to avoid disruptions has led to considerations of using non- traditional timekeeping systems, such as GPS Time or a time scale maintained by an individual government contractor. Instead, why don’t we just switch to using atomic time that is accurate, continuous and doesn’t vary for millions of years? The continuous use of a non-uniform time scale by including leap seconds, will definitely cause problems in many walks of life especially now that technology relies heavily on satellite communications that require precise timekeeping. Getting rid of leap seconds will imply moving forward and taking advantage of the new timekeeping methods. As much as we love our beloved earth, it is time to realize that celestial time is not every accurate in this new age of technological development and more precise methods of timekeeping.
A group called the Powers had their own thrones of doom and were the “most holy gods.” They held council which shows already that order and rule was important. The Powers chose to give names to different times of the day spanning morning, afternoon and night and so on. This structure allowed for a calendar-like count of the days and years so that people could keep track of time. If the sun was visible in one position it was a certain time and they’d know that next the sun would set and then the moon would begin to rise marking the end of a
For many Westerners, more specifically the driven citizens of the United States of America, time is viewed as a straight line. Our children realize this, consciously or not, early on. They make timelines in school, their classes switch on the hour, their intelligence is measured on a scale. We are born, we come of age during adolescence. We set a goal, we work to achieve success. Birth and death, childhood and adulthood are stages that occur only once. Life is black and white. Separate. The past is the past, the future is the future. Traveling on a straight line, we can only look forwards.
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.

Time is a difficult topic to handle in metaphysics; many problems arise. If you support A-series, which involves change, you are left to wonder the rate at which time passes. I cannot put my support behind static time; time appears to pass and in passing change occurs. The only aspect of time that appears to stay frozen are events in the past. However, events have to change from future to present and then to past before they can become static in the past. Even though there are clear objections to theories about time, I cannot support McTaggart’s bold claim that time is unreal. I can only look at time from my perspective. Ultimately there is so much change that occurs in me and around me as time passes that I cannot view time to be unreal and I am left to disregard McTaggart’s argument.
Just like all of Earth’s green, society too has found a simple way to use the sun to its fullest potential. Daylight Saving Time is a function that has allowed us to enjoy longer summer days simply by moving our clocks an hour ahead in the spring. This method had became something to consider since Ben Franklin idealized it. Of course it's not the same for everyone, depending on where you are may change when Daylight Saving Time occurs. Although some may say Daylight Saving Time is pointless, it is vital that DST has its benefits.
Daylight savings time has been something that individuals born post World War I have always had implemented in their lives. Many people never really consider the point of daylight savings time until it rolls around twice a year nor do they realize the original purpose. There are approximately 70 countries out of 196 that observe daylight savings time, at least in a portion of the country. Daylight savings time has had many changes throughout the history of it, but is it time to move on? Although there may be advantages such as more natural light, but disadvantages such as the disruptions with our circadian rhythms outweigh the advantages.
In 1952 W. F. Libby discovered a new method for calculating the age of organic material. Many people have been led to believe that carbon dating (and other radioactive dating methods) prove the Earth to be much older that 6000 years old (Biblical age).
The Tzolkin was also used as a means of divination and used as a guide for the performance of sacred rituals and ceremonies. Unlike other Maya calendar systems, such as the Long Count calender which is based on movements of the Sun, stars, and planets, the Tzolkin's 260 day cycle was derived solely from mathematics and wasn't based on any natural phenomenon at all. The Tzolkin calendar was made purely by mathematical calculations alone and merged with spiritual meaning for the performance of the Maya society's most sacred rituals, celebrations, and religious prophecies.
still didn’t have an extra quarter day for the earth to revolve around the sun. We have leap years every four years, adding a day to February, to do so. The Mayans wanted to create a calendar that would hold more time so they combined the Tzolk’in and the Haab calendars together to form the Calendar Round.

“Those who don’t know history are doomed to repeat it.” This famous quote from Edmund Burke is one that many of us are familiar with. In spite of this, many people disregard history, branding it as unimportant or irrelevant to modern-day situations. However, history is actually a quite important subject with a myriad of lessons to be learned for anybody to apply now and in the future. Additionally, history gives us much needed information about our past, keeping us from forgetting why our nations became the way they are. It allows us to draw parallels between modern events and past events to collect our best judgment and gives us the important knowledge of the origin of our modern world, giving extra credibility
History is a story told over time. It is a way of recreating the past so it can be studied in the present and re-interpreted for future generations. Since humans are the sole beneficiaries of history, it is important for us to know what the purpose of history is and how historians include their own perspective concerning historical events. The purpose and perspective of history is vital in order for individuals to realise how it would be almost impossible for us to live out our lives effectively if we had no knowledge of the past. Also, in order to gain a sound knowledge of the past, we have to understand the political, social and cultural aspects of the times we are studying.
First of all, to give you a better concept of time I will use a personal theory of mine. When you look up at the sky at night, at the stars, what are you seeing? Do you think that collage of stars actually exists? Most of them do not. When you look at the sky at night you are seeing the past because it takes an obscene amount of time for the light from those stars to reach earth, and in that time those stars may have disappeared.
For example, when looking into the next 30 years of artificial intelligence, the past 30 years are looked at as an indicator of what most likely will happen with future growth. It is thought linearly when in reality it should be exponentially. Trajectories will be far more accurate if taking current rate of progress and judging on that, however, it would still not be correct. In order to think correctly about the future, imagining things moving at a much faster rate than they are moving now should be taken into consideration (Tim
