Slicing the cake equally or engineering justice

Decorative photograph of sliced chocolate cakeIn support of the research being performed by one of the PhD students that I am supervising, I have been reading about ‘energy justice’.  Energy justice involves the equitable sharing of the benefits and burdens of the production and consumption of energy, including the fair treatment of individuals and communities when making decisions about energy.  At the moment our research is focussed on the sharing of the burdens associated with energy production and ways in which digital technology might improve decision-making processes.  Justice incorporates the distribution of rights, liberties, power, opportunities, and money – sometimes known as ‘primary goods’.  The theory of justice proposed by the American philosopher, John Rawls in the 1970’s is a recurring theme: that these primary goods should be distributed in a manner a hypothetical person would choose, if, at the time, they were ignorant of their own status in society.  In my family, this is the principle we use to divide cakes and other goodies equally between us, i.e., the person slicing the cake is the last person to take a slice.  While many in society overlook the inequalities and injustices that sustain their privileged positions, I believe that engineers have a professional responsibility to work towards the equitable distribution of the benefits and burdens of engineering on the individuals and communities, i.e., ‘engineering justice’ [see ‘Where science meets society‘ on September 2nd, 2015].  This likely involves creating a more diverse engineering profession which is better equipped to generate engineering solutions that address the needs of the whole of our global society [see ‘Re-engineering engineering‘ on August 30th, 2017].  However, it also requires us to rethink our decision-making processes to achieve  ‘engineering justice’.  There is a clear and close link to ‘procedure justice’ and ‘fair process’ [see ‘Advice to abbots and other leaders‘ November 13th, 2019] which involves listening to people, making a decision, then explaining the decision to everyone concerned.  In our research, we are interested in how digital environments, including digital twins and industrial metaverses, might enable wider and more informed involvement in decision-making about major engineering infrastructure projects, with energy as our starting point.

When less is more from describing digital twins to protoplasm

Word cluster diagramI spent several days last week reading drafts of PhD theses from two of my students.  I have three PhD students who are scheduled to finish their studies before Easter when they plan to start jobs that they have already been offered.  So, there is some urgency to their writing besides the usual desire to finish after three years or more of work on the same topic and the end of their funding.  Their relatively undiluted study of their topic can make it difficult for PhD students to see the big picture and write accessible descriptions of their research.  I have also encountered this challenge in describing our recent work on integrating digital twins to form an engineering metaverse.  There are dozens of published definitions of digital twins whereas the reverse holds for metaverses – no one really knows what they are.  Mary Midgley wrote, in her book ‘Beast and Man’, that descriptions should not be an account of everything about an entity or event but just enough to bring to our minds the appropriate conceptual scheme or construct that will tell us everything we need to know.  Our challenge as communicators is identifying the conceptual scheme that is needed, in other words selecting what matters and nothing else.  I like her example of an inappropriate description: “a section of protoplasm, measuring 1.76 meters vertically, emerged at 2:06 P.M. from hole in building at point x on plan and moved northward, its extremities landing alternately on concrete substratum, finally entering hole in further building, at point y on plan, at 2:09 P.M.”  If you need a conceptual scheme to understand this sentence, then try ‘a person walked across the road’.

Dressing up your digital twin

My research includes work on developing digital twins [see ‘Digital twins that thrive in the real world‘ on June 9th, 2021] of aircraft, power stations and other engineering systems.  And I am aware of similar work in other disciplines [see ‘Digital twins could put at risk what it means to be human‘ on November 18th, 2020]; but I was surprised to learn about the demand for digital clothing.  Three-dimensional virtual spaces or metaverses exist in computer games, chat rooms and more recently virtual spaces designed for socialising and shopping that are populated by avatars that need to wear something.  So, some fashion brands are producing digital clothing and charging you for the privilege of attiring your avatar with their logo.  In other words, you can buy clothes that don’t exist for people who are not real.  However, DressX has gone a step further producing a ‘digital-only collection’ of clothing for your digital twin or, at the moment, two-dimensional images of real people.  So, now you can buy clothes that don’t exist, superimpose them on pictures of real people, and upload the results to social media.  Perhaps it’s not as crazy as it seems at first because it might alleviate the need for fast fashion to produce single-use real clothes at enormous cost to the environment.  However, dressing up your digital twin does not seem to offer the same level of anticipation and excitement as getting dressed up yourself.
