Spending time in perspective

It might be useful to consider how I spend time. A considerable amount is used looking for my glasses. And I use more moving from one room to another and trying to remember why. Many 60+ people have those problems.

Time can be felt passing slowly or quickly. Scientists deal with it in chunks with nanoseconds at the short end and the big bang (13.8 billion years) at the long end.

But, for everyday purposes, we go from tenths of a second (think of athletics) through minutes, hours, days, years and sometimes decades. And we reckon 70 years to be a good innings for a human!  That means 3640 weeks or 25,480 days which includes a third for sleeping.

When people first evolved, their dealings with time would have been linked to nature

•    Sunrise (dawn) daytime Sunset (dusk) nightime
•    Summer, Autumn, Winter, Spring
•    The equinoxes – the longest and shortest days
•    Past present future

As science progressed clocks chopped time into smaller and more synchronised chunks and this linked to dividing the past into geological periods on planet earth and to happenings in the cosmos.
SO units of time at the extremes are hard to understand and few of us ever try. We rest content with the more hum drum middle ground and its tools e g diaries, calendars, and to-do-lists.

When the Good Lord created time he made plenty of it – but gave only the tiniest of chunks to me.

SO am I using it well in writing this note for my blog?

Notes -

• A nanosecond is an SI unit of time equal to one thousand-millionth of a second, that is, /1,000,000,000 of a second, or 10⁻⁹ seconds.
• Equinox -- the time or date (twice each year) at which the sun crosses the celestial equator, when day and night are of equal length (about 22 September and 20 March)
• A geologic period is one of several subdivisions of geologic time enabling cross-referencing of rocks and geologic events from place to place. These periods form elements of a hierarchy of divisions into which geologists have split the Earth's history.
