It was exactly 38 minutes ago that the time on my watch read 8:38 PM. I'm curious as to what time it is now.
Introduction: What is time, how do we measure it, and what does that mean for us?
For most of us, time is a critical aspect of our lives. We use it to plan and organize our days, weeks, and months. We use it to track the progress of our careers, relationships, and hobbies. Time can be a defining factor in whether or not we achieve our goals. But what is time really? And how do we measure it? These are some of the questions that researchers have been investigating for years.
What is time really?
Most people believe that time is a dimension that exists in space as well as in reality. This idea comes from the theory of relativity, which states that the laws of physics are the same for all observers moving relative to one another. According to this theory, there is no absolute frame of reference; each observer sees the Universe from his or her own perspective.
The Pre-industrial Age: Time as a measurement tool was nonexistent. Customs and rituals dictated when to act, eat, sleep, etc.
The pre-industrial age was a time when customs and rituals dictated when to act, eat, sleep, etc.. Time as a measurement tool was nonexistent. For example, in the ancient Greek world it was considered unlucky to count time aloud or divide it into hours. Instead, people relied on landmarks and the position of the sun to determine day and night. This method of timekeeping persisted in many parts of the world for centuries afterwards.
Because time was not a central focus in this era, measuring it often proved difficult. The Egyptians were one group who developed an accurate system of dating based on hieroglyphs. But even they could only estimate the passing of years by comparing drawings of animals and plants from different periods.
As civilizations grew more complex, their need for accurate timekeeping increased.
The Industrial Age: The first clock was created in the late Middle Ages. But it wasn't until the 1700s with the development of accurate timekeeping devices like pendulum clocks and pocket watches that people started to grasp the concept of time as a continuous thread throughout our lives.
Atomic Time: In 1927, scientists at the University of Chicago developed the atomic clock, which uses nuclear reactions to keep time accurately. Today, atomic clocks are used in many devices including GPS
Today, atomic clocks are the most accurate timepiece in use. These clocks use nuclear reactions to keep time accurately, and they are still in use today. The first atomic clock was invented by scientists at the University of Chicago in 1927.
