What’s in an image? Sometimes quite a lot, more than meets the eye.
I’m posting an image every day (or as often as I can). A photo, an image from the internet, a diagram or a map. Whatever takes my fancy.
There are few things as amazing as life. Perhaps there’s literally nothing as amazing as life in the entire universe! The photo shows the young, expanding leaves of a small-leaved lime tree (Tilia cordata).
Like all deciduous, temperate trees, leaf buds are formed the previous summer and over-winter after the old, mature leaves fall in late autumn. As temperatures increase in springtime, these buds swell and grow and the young leaves appear and expand. At first they’re a beautiful, pale green (lime green) but become a darker and duller shade as the days lengthen and they mature.
These processes all take place naturally in ways that are more complex than most of us might expect. Both plants and animal bodies are composed of countless tiny cells in much the same way that a large building might be made of bricks. Each cell is alive, contains a full copy of the organism’s DNA, and many of them have specialised roles to play. By cooperation and coordination they manage all the behaviours and activities that we see on the larger scale. So in some respects an expanding leaf is a lot like a growing community of people working together as a village or business. Having specialists makes it possible to do so much more, but cooperation becomes essential, not merely optional.
The rioting we’ve seen in some British cities in recent days has been disruptive and damaging to society as a whole. When the cells of an organism behave in uncoordinated and uncontrolled ways we call it a cancer. Rioting is a kind of cancer in a human society. We all know what happens when cancer becomes so widespread that the organism can no longer function. But organisms have ways of dealing with errant cells before they become overwhelming, and so do societies. Both police action and peaceful counter-demonstrations have been effective in controlling the UK riots in recent days.
