Time is an integral part of almost everything that we experience in our lives today. Almost everything that we do takes into consideration the time factor, whether it be the time taken to accomplish the task, or the time at which the task is expected to begin, or where it should end. The modern world also has an insatiable need to be as efficient as possible with regards to how time is spent. We always seem to be in a hurry.
Perhaps it is useful to understand/recognize that the pervasiveness of the “time-factor” in human experience is something that has changed over history, and that time was not this important in times past. (Some of you may already know the interesting story of the role played by the railroads in establishing time zones.) These days the concept of time has been taken to its limits, with even fractions of seconds becoming significant in our experiences. Athletic events are judged and winners determined by time differences that lie in the order of 100ths of seconds. The timing of signals in the electronics that we all use today is at the nanosecond level.
I cannot help feeling that the human entanglement with the concept of time is at an unhealthy extreme today, and that this is perhaps the result of the advancement of technology and also what we call progress. The way we interact with time today forms the basis of our continued existence as a civilization. There is no escaping it. (As an aside, it is interesting to note that physicists today are not even sure whether time exists at the most fundamental level of physical reality.)
But if we step back and and look at time from a more philosophical perspective, we can go in so many different directions with the theme! Time may sometimes be defined by a state of mind.
Finally, time is topic covered in a lot of music. Here is an oldie that I still enjoy listening to.
