Preparing for winter

I had been queueing slowly up the steps to board a plane thinking about nothing in particular when, as I stepped into the plane, one of cabin staff said to me ‘Are you getting ready for winter?’  I looked at her somewhat perplexed because it was only September, and she pointed to the book that I was holding ready to read on the flight home.  It was ‘Winter’ by Ali Smith.  It is a novel with much to say on many issues.

One of the central characters in the novel, Art writes a blog and someone challenges him to write about a real thing, something that he remembers happening and not a blog thing.  He describes a real childhood memory and when it is suggested that he should write about it, his response is he could never put something like that on-line because ‘it’s way to real’.  I have some empathy with Art, because it can be difficult writing about your thoughts and memories for anyone to read.  However, I have noticed that the readership of the blog goes up when I do write about such things [see for example ‘Thinking more clearly by writing weekly‘ on May 2nd, 2018 or ‘Depressed by exams‘ on January 31st, 2018].  So, if people are interested  perhaps I should do it more often.

Another passage that resonated with me was about age.  The narrator is her sixties, which I will be soon, and comments that ‘You never stop being yourself on the inside whatever age people think you are by looking at you from the outside.’  I think that this is true but perhaps difficult to reconcile with consciousness being an accumulation of sensory experiences [see ‘Is there a real ‘you’ or ‘I’‘ on March 6th, 2019]

Trees are amongst the slowest moving beings with which we share our world

Last month I mentioned that I started reading ‘Overstory’ by Richard Powers on my trip back from the US [see ‘When an upgrading is downgrading‘ on August 21st, 2019].  I only finished it about ten days ago because I have not had much time to read and it is a long book at 629 pages.  It is a well-written book including some quotable passages, but one that I particularly liked which seems relevant in this era of polarised perspectives: ‘The best arguments in the world won’t change a person’s mind.  The only thing that can is a good story.’  And, Richard Powers tells a good story about the destruction of the ecosystem, on which we are dependent, as a result of large-scale felling of ancient forests.  The emphasis should be on ‘ancient’ because time for trees appears to run at a different speed than for humans.  While we can observe the seasonal changes in an ancient woodland, we are barely conscious on the growth and movement of the woodland.  When we read Shakespeare’s lines in Macbeth about ‘Great Birnam wood to high Dunsinane Hill shall come’,  we think of it moving over the landscape at the speed of an army of people, whereas woods move so slowly that we do not live long enough to notice the change.  For instance, there is a spruce tree in Sweden that is 9,500 years old.  Our spatial understanding of a tree also leads to a misconception because we can only see the overstory, i.e. what is happening above ground; so, we think that each trunk is an individual tree, whereas for many types of tree many apparently individual trunks belong to the same organism with an extensive understory below ground which might be thousands of years old.  All trees are involved in a substantial understory communicating with each other in ways that we can barely imagine let alone comprehend.  Most of the ancient forests in Europe were cut down before science revealed the scale and complexity of life in them; yet, we still continue to fell forests as if there was an inexhaustible supply rather than one that could take as long to replicate as humans have been recording our history.

If you would like to arguments about trees then read ‘The Hidden Life of Trees’ by Paul Wohlleben, London: William Collins, 2017 (my title is a quote from this book).  If you are unconvinced then read the ‘Overstory’ by Richard Powers, London: Penguin (Vintage), 2019.

We inhabit time as fish live in water

A couple of weeks ago (‘Only the name of the airport changes’ on June 12th, 2019) I wrote about the stretching and compression of time while I waited for my much delayed flight to Reno. I mentioned Aristotle’s view of time as the measurement of change; however, Newton believed that time passes even when nothing changes. Einstein resolved the conundrum, represented by these different views, using the concept of a space-time domain forming a gravitational field containing waves. My title is a quote from Carlo Rovelli’s book, ‘The Order of Time‘. And, according to Rovelli, ‘mass slows down time around itself’, which I think will cause waves in the space-time domain .  Conservation of energy implies that the movement of an object will tend towards space where time passes more slowly, i.e. in the vicinity of large masses. Hence, things fall downwards because time runs more slowly close to the Earth. This implies that time passes more slowly at the airport than on the plane in flight; but, of course, the differences are too small for us to measure or perceive.

Relieving stress

I am relieving my ‘gadget stress‘ by ‘reading offline‘ and allowing some ‘mind wandering‘ to stimulate an increase in my intellectual productivity and creativity with the aid of some walks across green fields and cliff tops.  In other words, I have ‘gone walking‘ on a ‘deep vacation‘.  If you don’t have the opportunity for a vacation, then at least ‘Slow down, breathe your own air‘.
