Time is a really big four-letter word. We talk about it, write about it, measure it, but really no one quite knows what it is. Consider by analogy the fish living in water. Does it know or recognize the water. For the fish, water is almost unrecognized and surely unknown. Like time is for us. It is not known whether time has a direction. This means we don’t know if time is reversible. Most think time does have the proverbial arrow – no reversal. Physicists are especially interested in time, and what it means. Railroads live by it. Airlines mostly ignore it. Doctors never heard of it. Sometimes what a thing means is reflected in how we use it or modify it, as with an adjective. For time, there is a long list of at least fifty modifiers. Here are some of them. They betray both our confusion and our understanding of time. Look at all our needs for this basic quantity/concept in our lives. ample first long olden short
