Dwelling in the present

Photograph of St Michael's Church, Stoke Gifford

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”.

Time travel and rewriting history

2 Replies

decorative paintingI have written in the past about consciousness being an accumulation of sensory experiences [see ‘Is there are real ‘you’ or ‘I’? on March 6th, 2019].  Our memory consists of fragments of images, sounds, smells and feelings from the past that we can re-assemble into a complete experience often triggered by something in the present that resembles a fragment of a past experience.  We can time travel in our minds by thinking about the past.  It is so ubiquitous that we barely stop to think about it. Yet, we are fascinated by the possibility of time travel into the future.  However, our subconscious minds are constantly time traveling into the future [see ‘Predicting the future through holistic awareness’ on January 6th, 2021].  They are constantly making predictions about what will happen next, whether anticipating the path taken by a ball so that your hand can be positioned to catch it or picking up an umbrella as you leave the house so that you do not get soaked when it rains later in the day.  The further we attempt travel into the future the less dependable our predictions become and I suspect the same is true for travel backwards in time.  The reliability of our recollection of past experiences become less as time and entropy erode the connections between the fragments in our mind so that we struggle to reassemble all of the fragments in the correct order and our personal history is unintentional rewritten.

Reflecting on the lack of women in engineering

2 Replies

It was International Women’s Day last week which caused me to reflect on parlous state of the engineering profession.  Despite many initiatives and substantial expenditure of resources, the percentage of women in engineering in many Western countries has remained around 20% for most of my career.  For instance, in the UK, women made up 14.5% of all engineers in 2021 according to the Women in Engineering Society and 21.8% of women work in the engineering sector; while in the USA women secured 22% of all Bachelor’s degrees in engineering in 2018 (wwwstemwomen.com).  So, why have the many apparently well-supported initiatives made so little progress towards creating a gender-balanced profession?  Perhaps, they are not as well-supported within the engineering profession as they appear to be; or they are the wrong solutions for the problem because we do not understand the problem.  I suspect that both of these reasons for failure are relevant.  The lack of progress would suggest that most men in engineering are not worried that their profession is unrepresentative of the society it claims to serve and if they are concerned then they do not understand the issues sufficiently well to be able see a viable solution.  We can start to gain a better understanding by listening to women in science and engineering.  This can be done in everyday conversations, by attending events such as those organised on International Women’s Day, or by reading about women’s experiences such as in ‘Invisible Women: exposing data bias in a world designed by men’ by Caroline Criado Perez or in ‘A Fly Girl’s Guide to University: being a woman of colour at Cambridge and other institutions of power and elitism’ by Lola Olufemi, Odelia Younge, Waithera Sebatindira and Suhaiymah Manzoor-Khan.

Separating yourself from existence

Leave a reply

The French novelist Michel Houellebecq has written of the power of literature to separate yourself from your existence. It is something that I experience when reading an absorbing novel or occasionally when reading an outstanding scientific paper on a subject that interests me. However, it happens more often when I am writing and perhaps is a reason why I write regularly and frequently. Houellebecq has also written that ‘only literature can give you the sensation of contact with another human mind’ [in Submission, 2015]. Is it only literature that can produce this sensation? Or, does it occur when you listen to an in-depth interview or even when you read posts regularly from a blogger? Perhaps after 500 posts [see ‘500th post‘ on February 2nd, 2022] you have a sensation of contact with some part of my mind.
