The picture shows a little collection of pebbles and a shell that sits on the desk in my office. There are similar collections in various locations at home and some of my coats have a pebble permanently in one pocket – there’s even a shell on the dashboard of our car. They have all been picked up during walks on beaches [see my post entitled ‘Take a walk on the wild side‘ on 26th August 2015] and serve as reminders of the ‘slowness’ enjoyed on vacation [see my post ‘Slow down, breathe your own air‘ on December 23rd, 2015]. Barbara Hepworth owned a similar collection of stones that you can see in the Hepworth Wakefield. On the subject of this habit she wrote in 1961: ‘Many people select a stone or a pebble to carry for the day. The weight and form and texture felt in our hands relates us to the past and gives us a sense of a universal force. The beautifully shaped stone, washed up by the sea, is a symbol of continuity, a silent image of our desire for survival, peace and security.’ I could not express it better so I didn’t try.
The quote is from a contribution to the film Barbara Hepworth directed by John Read, BBC TV, 1961 and can be found in Barbara Hepworth: Writings and Conversations, edited by Sophie Bowness, London: Tate Publishing, 2015.
At the Airbus PhD workshop that I attended a couple of weeks ago [see my post entitled Making Engineering Work for Society on September 13th 2017], Axel Flaig, Head of Airbus Research and Technology, gave us an excellent opening presentation describing their vision for the future. Besides their vision for the next generation of passenger aircraft with reductions in CO2, NOx and noise emissions of 75%, 90% and 65% respectively against 2000 levels by 2050, they are also looking at urban air mobility. We have 55 megacities [cities with a population of more than 10 million] and it is expected that this will increase to 93 by 2035 [see my post entitled ‘Hurrying Feet in Crowded Camps’ on August 16th, 2017]. These megacities are characterized by congestion and time-wasted moving around them; so, Airbus is working on designs for intra-city transport that takes us off the roads and into the air. Perhaps the most exciting is the electric Pop.up concept that is being developed with Italdesign. But, Airbus are beyond concepts: they have a demonstrator single-seater, self-pilot vehicle, the Vahana that will fly in 2017 and a multi-passenger demonstrator scheduled to fly in 2018.
Soon, we will have to look left, right and up before we cross the road, or maybe nobody will walk anywhere – though that would be bad news for creative thinking [see my post on ‘Gone Walking’ on 19th April 2017], amongst other things!
Last week I attended a one-day workshop for PhD students sponsored by Airbus. Most of the students produced a poster describing their research; and a dozen brave ones gave a three-minute presentation on their PhD thesis. It’s a challenge to describe three years of research in three minutes to an audience that are not experts in your specialist field. However, the result was an exciting and stimulating morning covering subjects as diverse as multidisciplinary design optimization and cognitive sources of ethical behaviour in business. The latter was presented by Solenne Avet who was the only woman amongst the twelve three-minute thesis presenters. The gender diversity was better for the other, longer talks with two women out of six presenters. Interestingly, the female PhD students were the only ones tackling the interaction between engineering and human behaviour, including system-human communication, collective engineering work and innovation processes, which I have suggested is essential for viable engineering solutions to our global and societal challenges [see my post ‘Re-engineering engineering’ on August 30th, 2017]. This population sample is too small to make a reliable generalization; however, it suggests that a gender-balanced engineering profession would be more likely to succeed in making substantial contributions to our current challenges [see UN Global Issues Overview].
While we were sitting in the Red Deer in Sheffield enjoying a couple of pints of Iron & Steel Bitter from the Chantry Brewery in Rotherham, my long-time Swiss collaborator, and sometime correspondent on this blog, asked me: what’s the difference between an ale and a beer? And, I had to admit that I couldn’t provide a definitive answer to satisfy his curiosity. So, I am going to have another go, now. Beer is an alcoholic drink made from a cereal grain and, according to the Oxford English Dictionary, ale is any beer other than lager, stout, or porter!
However, ‘real ale is a beer brewed from traditional ingredients (malted barley, hops water and yeast), matured by secondary fermentation in the container from which it is dispensed, and served without the use of extraneous carbon dioxide‘ according to CAMRA, the Campaign for Real Ale. So the Iron & Steel Bitter that we enjoyed at the Red Deer was a real ale.
My digital detox during July [see my post entitled ‘In digital detox‘ on July 19th, 2017] included sampling bottled ales from local West Country breweries and the photograph shows my favorites ranked from left to right. Many were enjoyed while overseeing the BBQ in the picture below; however, the time in the Red Deer involved some rather more productive brain-storming for the MOTIVATE project [see my post entitled ‘Getting smarter‘ on June 21st, 2017].
