We have no trouble recovery it, losing it, spending it, or killing it, but defining time is an additional one matter. Even though time is an integral part of our lives, we nothing else but don't know what it is. We portion it with clocks and calendars, but it remains an elusive abstract idea.
A psychologist may say time exists only in your head and keeps yesterday's events from bumping into today's. For a physicist, time is a fundamental property, along with mass and distance. And yet time has none of the physical characteristics of either. Our senses let us judge differences in distance or mass, but time offers nothing to see, feel, hear, taste, or smell.
It doesn't help the effort to pin down the meaning of time when we use the word in two definite ways. Time may refer to the interval measured in the middle of two points, such as how long it takes to run a foot race. Time is also used to define a definite moment, such as when the race started. The definite moment the race starts is a unique event and can only happen once. But time intervals are repeatable. So the time required to run the race may be equaled again in hereafter races.
Despite our inability to exactly understand what time is, we use it effectively in many ways, especially in quantifying intervals. From computers to satellites, our technology requires the potential to nothing else but count time periods. The clock on a laptop may be a poor timekeeper, but the central processing chip controlling the computer must be able to accurately portion millionths or billionths of a second.
Time intervals also let us look into the past. Radioactive dating is able to rule the age of geologic formations or the approximate date a living thing died. Radioactive isotopes found in rocks or living things are known to emit radiation at a predictable rate. By comparing the amount of radioactive material today with what was originally present, the time which has passed can be calculated.
Our mind can't portion radioactivity or count in millionths of a second, but it does have the potential to use time in a unique way. Only the human brain is able to use experiences and data from the past to make plans for the future. Animals don't share this recognition of the continuum of time and can't impart the past to the gift or future.
For instance, if you're training a pet, you need to repaymen it at the time it performs the desired action. Animals don't join together a repaymen to something they did even minutes before. But humans don't need instant gratification. We can work for years before receiving part of our repaymen in the form of a relinquishment pension.
However, this human characteristic takes time to develop. Until about six, a child's brain has an inability similar to animals to fully join together assorted events in time.
In the end, defining time may be like trying to define pornography. It's difficult to nothing else but say what it is, but you know when you see it.
