Time and the Clocks Essay Introduction It is well known that technology is very important aspect in human life and Critical Engagement with Technology class held lot of concepts and theories with regard to how to look at and understand technology that helped in changing some of the previous understandings. The class helped in developing the skills to be able to evaluate different approaches and ways of thinking in regards to understanding technology. Also to know the issues that impact the management of technology and how the technology influenced managers’ abilities to provide better management of both resources and people. The class also examined the drivers and factors that impacted technology implementation such as social, political, economic, among others. The new way of thinking about the technology and how it is driven was presented in class through several topics that was introduced such as: â€Å"Nothing New Under the Sun†, Historical Perspective on Technology The Industrial Revolution Technology as the Context for and Product of Human Endeavour Technological Determinism Social Shaping of Technology Management, Power and Technology The course further gave us the opportunity to pick a technology and ably what we learned in the class. Our case study that we picked talked about the clocks and how the society shaped the way of measuring time throughout history. The clock nowadays are technology that has been taken for granted. The focus of this case study is to show the importance of time measurement and how our life nowadays revolves around it. By going through history all the way from using the sun and stars to the development of clocks that neither lose nor gain one second in 200 million years to show how humanity searches for more accuracy by developing the tools to measure the time. Literature Review As mentioned earlier, the course provided us with lot of concepts and theories with regards to technology that in turns helped in understanding and facilitating of our case study. Concepts such as Technological Determinism and Social Shaping of Technology helped in carrying out our research and that is why it is important to define them. The idea of that technology development affect and shape the society is called Technological Determinism and it implies that the technology changes by following its own logic and come from outside society. Hard technological determinism which lays on simple cause-and-effect and not considering other factors such as economic, political, cultural, among others is considered as an oversimplified theory for the technological change. This was the common way of thinking that encourage the passive attitude toward technology change. It is worth mentioning that new technology are developed from an existing technology or a combinations of several existing technologies through a gradual change. Therefore, the social shaping of technology theory critique the technological determinism theory and suggests that society has more active attitude toward technology development in the since that society decides what and how to use it. Also the social shaping of technology theory consider other factors mentioned previously that affect the technology wheel of development (Mackenzie and Wajcman, 1999). Having said that, the distinguish between the two theories among the other topics learned in this course open our minds as well as provided us with better understanding of technology development. The Beginnings of the Clocks The movement of earth and its moon gave the indications for the year, month, and day. Human invented the hours, minutes and seconds as smaller units for the time. Middle East ancient civilization divided the day into 24 hours with 60 minutes an hour and 60 seconds a minutes. At the beginning there were the sundials and the water clocks that didn’t give exact time but rather represent the flow of time (Franz, 1978) (Dale, 1992). Before the mechanical clocks, people had many attempts to find a tool to measure time more accurately. The candle clock which was basically a candle with the hours marked on it was one device. Another device was the hourglass or sandglass that was used at sea and it required someone to stay next to it to flip it because each flip was counted as half an hour or an hour. Although both devices were used at night and that helped in solving the problem of the sundial that depends on the sun, another problem came to realization which was that these devices didn’t give the time of the day rather they only measured periods of time (Dale, 1992). People of ancient China, Babylon, and Egypt discovered the link between timekeeping and the positions of stars due to the fact that stars changes position in a regular pattern. This link motivated people to find new ways to measure time more accurately especially at sea (Dale, 1992). Pope Sylvester II invented the first mechanical clock in year 1000 and they spread among European cathedrals by 1300. They were used to inform people about the time they should go to church and that was the early use for them. Some of these clocks gave astronomical information and others had bells to call people (Sherman, 2005). It is interesting that an old mechanical clock that was built in 1386 is still working in England in Salisbury Cathedral. The small clocks didn’t come along until after the invention of mainspring and those clocks were built for wealthy people where they were considered as valuable possessions that they show off with. Marine Navigation When the magnetic compass were invented, it was used by sailors to steer the ships in an accurate direction, but compasses weren’t steady enough in rough weather and hence deciding the direction based on them was difficult. The Sextant was the next invention and it was the instrument used to measure the heights of the sun in order to calculate the ship’s latitude (May, 1973) (Cotter, 1977). All these instruments solve part of the problem because there were no means to measure the longitude and the position of the ships on the latitude was purely based on the sailors’ guess (Cotter, 1977). The speed of ships is measured by knots and it is based on an old method called the ‘Dead Reckoning’. After plotting the course using the compass, a rope with several knots on it with a log at the end of that rope were thrown overboard. Then a sandglass was used to measure the period. When it was time the rope was pulled and the knots were counted. Using this method sailors were able to calculate the distance they sailed (May, 1973) (Gould and Dyson, 1976). The compass, astrolabe and the dead reckoning were the only methods used by the great explorers like Ferdinand Magellan and Christopher Columbus and what is more interesting is that they didn’t have a particular destination when they discovered the new lands. These discoveries provided the opportunity of trading but another problem of navigation came up. No one was able to know how long the trip going to take or how much food they should take with them to feed the crew of the ship. Fresh food rotted before they reach their destination along with other problems caused by the poor navigation at that time. Knowing the longitude and better timekeeping was the answer. Cotter (1977) stated that the difference between the time readings in two different places will help in calculating the longitude. For this calculation to be possible a standard time was needed. Since Britain was the leading seafaring nation in the 17th century it decided to take the Royal Observatory at Greenwich as the standard time and the longitude passing through Greenwich became 0 degrees. At that time other countries took different places as mark 0 degrees. When the radio were used as the mean of communication between ships, Greenwich system was used internationally in 1884. Mechanical clocks provided more accurate measurement of time than candles or sandglasses, but still they were not accurate enough because the swinging of the pendulum was upset by the motion of the ships. The early mechanical clocks needed to be checked against other clocks or against the sun on a frequent bases. Sailors knew that they needed a clock that keep the accurate standard time even under that challenging conditions of the sea. According to Gould and Dyson (1976) the British government was alarmed by the fact that lots of ships both merchant and naval were lost due to the hazardous conditions of the Atlantic Ocean. And that is why the government announced a competition in 1714 with a prize of ? 20,000 for a chronometer with specific criteria. The British government wanted an accurate chronometer that gives the correct longitude reading within 55 kilometres after six weeks of sailing. In order to be that precise, the new chronometer must not loss nor gain more than three seconds per day also it should be able to cope with the conditions of the sea such as the salty sea air and the temperature and humidity changes. At that time no clock was able to achieve that accuracy and it was a big technical challenge. In 1759, John Harrison, who was a clockmaker, succeeded after three previous attempts in inventing the perfect chronometer. The chronometer was tested by Harrison’s son William when he sailed to Jamaica two years after the invention came to light. Harrison’s chronometer passed the test. It only lost an average of 2. 7 second a day and it was able to give an accurate longitude reading within 30 kilometres. It is worth mentioning that chronometers were not used generally until 1800 and this is because it was very expensive to build one. Navigation problems were solved by using the clocks and the seas became busy highways at that time (Gould and Dyson, 1976). Railways Time The industrial revolution was powered by the steam power as well as the revolution in transport where the railways spread quickly at that time. The main purpose of the railways was to transport coal although it was used to transport passengers too. By making the transport easier people’s lives has changed. In the early days of railways public clocks weren’t synchronized and there wasn’t a single standard time. The trains were separated and spread along the tracks using time intervals system and that caused problems for travellers as well as posed a safety hazard. With the introduction of railways time that used Greenwich Mean Time the public timekeeping has changed and that solved the problems of railways. Moreover, the demand for more accuracy in daily tasks were influenced by railway time. It is worth mentioning that it took the government 40 years since the introduction of railways time to legislate the standard time for Great Britain and that was in 1880 (Schivelbusch, 1986). The Industrial Revolution Commodities and industries were made in a different way in Europe after 1780 and that is why historians gave the name the industrial revolution. In this revolution, cheaper and faster machines replaced the costly and slow manual crafts. For example, cotton industry changed a lot, at first cotton was woven manually and it was considered as luxury but with the industrial revolution and the introduction of the new cotton mills, the production become faster and that caused the price to drop drastically for the product. Moreover, this movement puts lot of people out of work and the only thing that they could do at that time is to work in the mills. This movement also introduced many people to the important of time. Factories’ machines were kept running for long time during the day for the investors to gain the best return and it was important that workers arrive on time. Workers who came late were usually punished with a fine deducted from their weekly payments. At that time only few people had clocks to tell them the time other used the ‘knocker-up’ who was someone walking around and waking people to go to work (Cardwell and Cardwell, 2001). The method of workers payments changed due to this movement too. Before works used to earn fixed payments for a day of work but when the factories started to use the shift system workers started to be paid using hourly rate. This was possible with the invention of a machine that kept record of how many hours the worker actually worked. The worker had to stamp a card using that machine that showed the time of start and end. That process was called ‘clocking on-clocking off’ (Cardwell and Cardwell, 2001). Time Control Reeves and Duncan et al. (2001), Webster and Davies et al. (2011), and Borst (1993) agreed upon that ‘Time and motion study’ which was developed by Frederick Taylor in 1880 helped in studying different factories operations to speed them up by identifying what is really needed and that in return helped manufacturers to use their workers and machinery more efficiently. The concept of saving the time became an important one when the awareness of time increased. That concept pushed lot of technologies to be invented especially after the invention of electricity to replace the boring and routine tasks such as cleaning, washing clothes, among others. Another form of time control was the use of time switches which were basically a clock combined with a switch that enabled automatic turning on and off for the devices. More accurate clocks Wagner (2008) said that the work of most specialists such as engineers, physicists, among others depends heavily on precise time measurements. Nowadays, 300 atomic clocks at different laboratories are used to calculate global time. But researchers are pursuing more accuracy in time measurement and the results will replace the process of averaging the data from the atomic clocks. Researchers developed optical clocks that capture and measure the frequencies of strontium atoms (a chemical element with atomic number 38) by using the lasers. With the ability of the new clocks to measure the oscillation at higher frequency ranges, the results are clocks that measure time more accurately. Also these new clocks are expected to measure time in intervals much smaller than what the atomic clock that will help in giving the clock that ability to neither lose nor gain one second in a period of 200 million years (Wagner, 2008). Methodology Before us as a group decided on the topic in hand we had lot of discussions with lot of topics to talk about. After we reached an agreement we distributed the work and each of the members had to research a specific period in time to find out more about time and clocks. It was an interesting task that expanded my knowledge about the subject. After each member focused on the topic assigned our group met to share the findings. Comments were exchanged to further address the subject from different angles. The researches were done using books, online articles, and journals. The group met for the second time with the new findings and slides for the presentation. The presentation was put together and rehearsed. We didn’t have to meet as much because we used methods such as blogs and dropbox to share our work and discuss further. I was assigned with the topic regarding the marine navigation and the early problems and I found out that different resources agreed and have the same facts about the subject. Also I was able to dig deeper and find interesting facts with regards to other topics in this document that in turn helped me gain immense knowledge about the theories proposed as well as provided me with the comprehensive understanding I was seeking. Findings and Discussion I was able to carry out this case study and research with most open mind and with referring to the theories and topics learned in class. I found out that the clocks is considered as one of the oldest inventions in history and also how humanity is continuously seeking for more accuracy in regards to time measurement even nowadays. Also I found out how the concept of time measurement affect and pushed other technologies to emerge and how it was used in the industrial revolution era. It is clear that throughout history human had the same idea which was the important of measuring time. What differs was the development of the devices that measure the time in a more accurate manner. It is also observed that the development of the device depends on the same concepts of the previous ones but with better ways of doing it. Early sailors used land marks and stayed close to the land in order to find their way and to know their position. Then sailors become more adventurist over time and started to find new ways to help them navigate in the open sea. Methods such as astronomy observation helped in calculating the ships’ locations to work out the directions and set the course of the ship by using an instrument called the astrolabe. The astrolabe was the tool used by the ancient Greeks, but the biggest default was it needed a clear sky and it was only used at night. With the invention of the chronometer that solved the marine problems I felt that it was one of the breakthroughs in the world of clocks that help in measuring the time more precisely. It showed that the need of the accuracy in the time measurement was a social need to solve the problems rather than resulting from technological determinism. It is hard nowadays to find someone who doesn’t care about time. This is showed by the fact that everything in the modern life had something to do with time and clocks. For example, the personal computers where the clock is installed as a ship in the heart of the device to regulate the electrical signals (Borst, 1993), the use of the timer in the microwave, setting the alarm to go to work or school, transportation timetable, among other examples. Clocks is everywhere but as mentioned before, it is a technology taken for granted. Conclusion. The clocks development throughout history showed a true evident of the society shaping the technology changes with the need of finding ways to measure time more accurately. Also the history showed that the clocks came a long way and the development and researches for more accurate clocks is still going on. The clocks began with using the sun and the stars. Then they were used to count periods using water clocks, candle clocks, and sandglass clocks. After that mechanical clocks came to light with the use of gears and motion. And with the need for a clock to per the sea conditions and to give accurate longitude readings, the chronometer came about. Finally, reaching to the atomic clocks that we use nowadays to measure time and for the future the use of optical clocks that measure time with smaller intervals than ever. With the development of the clocks we can observe how people lives changed. Not forgetting about the disadvantages where some people suffer from something called ‘time stress’ and this is because we want to do lots of things and the clashes among them caused by the time constrains lead to stress.
