You can only go there in your head

“Inner space and outer space are similar, aren’t they really?  You’re never going to get to the edge of the universe in a spaceship.  You might as well try going on a bus.  You can only go there in your head.”  This is a quote from David Hockney in ‘Spring Cannot Be Cancelled‘  by David Hockney and Martin Gayford.  It’s a beautiful book.  Full of thought-provoking insights and recent artwork by Hockney painted in Normandy mainly during the pandemic.  I read it last month while in the Yorkshire Dales [see ‘Walking the hills‘ on April 13th 2022].  Hockney writes about his need to paint.  He finds it utterly absorbing and endlessly sustaining.  Gayford compares this need and experience to the work of American psychologist, Mihaly Csiksczentmihalyi [see ‘Slow-motion multi-tasking leads to productive research‘ on September 19, 2018] who wrote about concentration so intense that there is no spare capacity to think about anything else, your self-consciousness disappears and you lose your sense of time leading to a deep sense of happiness and well-being.  I cannot paint but I can achieve something approaching a similiar state when I am writing.

Existential connection between capitalism and entropy

global average temperature with timeAccording to Raj Patel and Jason W Moore, in his treatise ‘Das Kapital’ Karl Marx defined capitalism as combining labour power, machines and raw materials to produce commodities that are sold for profit which is re-invested in yet more labour power, machines and raw materials.  In other words, capitalism involves processes that produce profit from an economic perspective, and from a thermodynamic perspective produce entropy because the second law of thermodynamics demands that all real processes produce entropy.  Thermodynamically, entropy usually takes the form of heat dissipated into the environment which raises the temperature of the environment; however, it can also be interpreted as an increase in the disorder of a system [see ‘Will it all be over soon?’ on November 2nd, 2016].  The ever-expanding cycle of profit being turned into capital implies that the processes of producing commodities must also become ever larger.  The ever-expanding processes of production implies that the rate of generation of entropy also increases with time.  If no profit were reinvested in economic processes then the processes would still increase the entropy in the universe but when profit is re-invested and expands the economic processes then the rate of entropy production increases and the entropy in the universe increases exponentially – that’s why the graphs of atmospheric temperature curve upwards at an increasing rate since the industrial revolution.  As if that is not bad enough, the French social economist, Thomas Piketty has proposed that the rate of return on capital, “r” is always greater than the rate of growth of the economy, “g” in his famous formula “r>g”.  Hence, even with zero economic growth, the rate of return will be above zero and the level of entropy will rise exponentially.  Piketty identified inequality as a principal effect of his formula and suggested that only cataclysmic events, such as world wars or revolutions, can reduce inequality.  The pessimistic thermodynamicist in me would conclude that an existential cataclysmic event might be the only way that this story ends.

Intelligent openness

As an engineer and an academic, my opinion as an expert is sought often informally but less frequently formally, perhaps because I am reluctant to offer the certainty and precision that is so often expected of experts and instead I tend to highlight the options and uncertainties [see ‘Forecasts and chimpanzees throwing darts’ on September 2nd 2020].  These options and uncertainties will likely change as more information and knowledge becomes available.  An expert, who changes their mind and cannot offer certainty and precision, tends not to be welcomed by society, and in particular the media, who want simple statements and explanations.  One problem with offering certainty and precision as an expert is that it might appear you are part of a technocratic subset seeking to impose their values on the rest of society, as Mary O’Brien has argued.  The philosopher Douglas Walton has suggested that it is improper for experts to proffer their opinion when there is a naked assertion that the expert’s identity warrants acceptance of their opinion or argument.  Both O’Brien and Walton have argued that expert authority is legitimate only when it can be challenged, which is akin to Popper’s approach to the falsification of scientific theories – if it is not refutable then it is not science.  An expert’s authority should be acceptable only when it can be challenged and Onora O’Neill has argued that trustworthiness requires intelligent openness.  Intelligent openness means that the information being used by the expert is accessible and useable; the expert’s decision or argument is understandable (clearly explained in plain language) and assessable by someone with the time, expertise and access to the detail so that they can attempt to refute the expert’s statements.  In other words, experts need to be  transparent and science needs to be an open enterprise.

Dwelling in the present

St Michael’s Church, Stoke Gifford

I have been visiting the Airbus site at Filton near Bristol since the mid-1990s. It is where the wings for new designs of aircraft are developed and tested. My involvement has been in the developing of techniques for measuring strain in aircraft structures during static and fatigue tests. At the moment, we are working on methods to integrate fields of measurements with computational predictions of stress and strain [see ‘Jigsaw puzzling without a picture‘ on October 27th, 2021]. I frequently travel by train to Bristol Parkway Station and walk past the church in the photograph without even noticing it despite it being next to the station. To be fair, the view of it from the station entrance is obscured by a billboard. However, last week as I walked back to the station with a half-hour to spare, I noticed a gate leading into a churchyard. I slipped through the gate thinking that perhaps there might be an interesting old church to explore but it was locked and I had to be satisfied with a stroll around the churchyard. I was slightly shocked to realise the church, and the village green beyond it, had been hidden in full view for more than thirty years of walking within a few tens of metres of it perhaps once a month. I had always been too focussed on the research that I was heading to Airbus to discuss, or too tired at the end of a day, to notice the things around me. Our senses flood our brains with information most of which is ignored by our conscious minds that are busy time traveling through past memories or looking into the future [see ‘Time travel and writing history‘ on March 23rd, 2022].  However, there is pleasure to be gained by dwelling in the present and exploring the sensory experience flooding into our brains.  As Amy Liptrot commented in her book ‘The Outrun‘, “the more I take the time to look at things, the more rewards and complexity I find”.
