My Engineering Day

Photograph of roof tops and chimneys in Liverpool.Today is ‘This is Engineering’ day organised by the Royal Academy of Engineering to showcase what engineers and engineering really look like, celebrate our impact on the world and shift public perception of engineering towards an appreciation that engineers are a varied and diverse group of people who are critical to solving societal challenges.  You can find out more at https://www.raeng.org.uk/events/online-events/this-is-engineering-day-2020.  I have decided to contribute to ‘This is Engineering’ day by describing what I do on a typical working day as an engineer. 

Last Wednesday was like many other working days during the pandemic.  I got up about 7am went downstairs for breakfast in our kitchen and then climbed back upstairs to my home-office in the attic of our house in Liverpool [see ‘Virtual ascent of Moel Famau’ on April 8th, 2020].  I am lucky in that my home-office is quite separate from the living space in our house and it has a great view over the rooftops.  I arrived there at about 7.45am, opened my laptop, deleted the junk email, and dealt with the emails that were urgent, interesting or could be replied to quickly.  At around 8am, I closed my email and settled down to write the first draft of a proposal for funding to support our research on digital twins [see ‘Tacit hurdle to digital twins’ on August 26th, 2020].  I had organised a meeting earlier in the week with a group of collaborators and now I had the task of converting the ideas from our discussion into a coherent programme of research.  Ninety caffeine-fuelled minutes later, I had to stop for a Google Meet call with a collaborator at Airbus in Toulouse during which we agreed the wording on a statement about the impact our recent research efforts.  At 10am I joined a Skype call for a progress review with a PhD student on our dual PhD programme with National Tsing Hua University in Taiwan, so we were joined by his supervisor in Taiwan where it was 6pm [see ‘Citizens of the World’ on November 27th, 2019].  The PhD student presented some very interesting results on evaluating the waviness of fibres in carbon-fibre composite materials using ultrasound measurements which he had performed in our laboratory in Liverpool.  Despite the local lockdown in Liverpool due to the pandemic, research laboratories on our campus are open and operating at reduced occupancy to allow social distancing.

After the PhD progress meeting, I had a catch-up session with my personal assistant to discuss my schedule for the next couple of weeks before joining a MS-Teams meeting with a couple of colleagues to discuss the implications of our current work on computational modelling and possible future directions.  The remaining hour up to my lunch break was occupied by a conference call with a university in India with whom we are exploring a potential partnership.  I participated in my capacity as Dean of the School of Engineering and joined about twenty colleagues from both institutions discussing possible areas of collaboration in both research and teaching.  Then it was back downstairs for a half-hour lunch break in the kitchen. 

Following lunch, I continued in my role as Dean with a half-hour meeting with Early Career Academics in the School of Engineering followed by internal interviews for the directorship of one of our postgraduate research programmes.  At 3.30pm, I was able to switch back to being a researcher and meet with a collaborator to discuss the prospects for extending our work on tracking synthetic nanoparticles into monitoring the motion of biological entities such as viruses and bacteria [see ‘Modelling from the cell through the individual to the host population’ on May 5th 2020].  Finally, as usual, I spent the last two to three hours of my working day replying to emails, following up on the day’s meetings and preparing for the following day.  One email was a request for help from one of my PhD students working in the laboratory who needed a piece of equipment that had been stored in my office for safekeeping.  So, I made the ten-minute walk to campus to get it for her which gave me the opportunity to talk face-to-face with one of the post-doctoral researchers in my group who is working on the DIMES project [see ‘Condition-monitoring using infra imaging‘ on June 17th, 2020].  After dinner, my wife and I walked down to the Albert Dock and along the river front to Princes Dock and back up to our house.

So that was my Engineering Day last Wednesday!

Lacking creativity

detail tl from abstract painting by Zahrah RI feel that I am moving to the next level of experience with online meetings but I am unsure that it will address the slow down in productivity and a loss of creativity being reported by most leaders of research groups to whom I have spoken recently.  About a month ago, we organised an ‘Away Day’ for all staff in the School of Engineering with plenary presentations, breakout groups and a Q&A session.  Of course, the restrictions induced by the pandemic meant that we were only ‘away’ in the sense of putting aside our usual work routine and it only lasted for half a day because we felt a whole day in an online conference would be counter productive; nevertheless, the feedback was positive from the slightly more than one hundred staff who participated.  On a smaller scale, we have experimented with randomly allocating members of my research team to breakout sessions during research group meetings in an attempt to give everyone a chance to contribute and to stimulate those serendipitous conversations that lead to breakthroughs, or least alternative solutions to explore.  We have also invited external speakers to join our group meetings – last month we had a talk from a researcher in Canada.  We are trying to recreate the environment in which new ideas bubble to the surface during casual conversations at conferences or visits to laboratories; however, I doubt we are succeeding.  The importance of those conversations to creativity and innovation in science is highlighted by the story of how Emmanuelle Charpentier and Jennifer Doudna met for the first time at a conference in Puerto Rico.   While wandering around San Juan on a warm Caribbean evening in 2011 discussing the way bacteria protect themselves against viruses by chopping up the DNA of the virus, they realised that it could be turned into molecular scissors for cutting and editing the genes of any living creature.  They went home after the conference to their labs in Umea University, Sweden and UC Berkeley respectively and collaborated round the clock to implement their idea for which they won this year’s Nobel Prize for Chemistry.  Maybe the story is apocryphal; however, based on my own experience of conversations on the fringes of scientific meetings, they are more productive than the meeting itself and their loss is a significant casualty of the COVID-19 pandemic.  There are people who point to the reduction in the carbon footprint of science research caused by the cancellation of conferences and who argue that, in order to contribute to UN Goals for Sustainable Development, we should not return to gatherings of researchers in locations around the world.  I agree that we should consider our carbon footprint more carefully when once again we can travel to scientific meetings; however, I think the innovations required to achieve the UN Goals will emerge very slowly, or perhaps not all, if researchers are limited to meeting online only.

Slow progress replacing 150 year old infrastructure

Photograph of salvaged section of original gas mainThe Liverpool Gas Light Company was formed in 1816, just as the amount of carbon dioxide in the atmosphere started to rise above the pre-industrial revolution level of 278 ppm. A rival Oil Gas Company was formed in 1823 and became the Liverpool New Gas and Coke Company in 1834. The two rival companies merged in 1848. Last year a piece of cast iron gas main from around this period was salvaged while replacing a gas main on the Dock Road in Liverpool. It was date-stamped 1853. For the last month, works have been underway to replace the original gas main in our street which appears to be of a similar age. The concept of gas-fired central heating using pressurised hot water was developed in the 1830s by Angier March Perkins [1838 US patent], amongst others; but did not become fashionable until the 1850s which coincides approximately with laying of the original gas main in the road outside our house. There is a cavernous coal hole under the pavement (sidewalk) in front of our house which would have been used to store coal that was burned in fireplaces in every room. So, we can deduce that the house, which was built in the early 1830s, did not initially have gas-fired central heating but that it could have been installed sometime in the second half of the 19th century, just as the level of carbon dioxide in the atmosphere started its exponential increase towards today’s level of 412 ppm [monthly average at Mauna Loa Global Monitoring Laboratory for August 2020].  Carbon dioxide represents about 80% of greenhouse gas emissions, according to the US EPA, and heating of commercial and residential properties accounts for 12% of these emissions in the US and for 32% in the UK.  Hence, before our house is two hundred years old, it is likely that we will have converted it to electrical heating in order to reduce its carbon footprint.  We have made a start on the process but it is pointless until our power supply is carbon neutral and progress towards carbon neutrality for electricity generation is painfully slow in the UK and elsewhere [see ‘Inconvenient facts‘ on December 18th, 2019].

Shaping the mind during COVID-19

Books on a window sillIf you looked closely at our holiday bookshelf in my post on August 12th 2020, you might have spotted ‘The Living Mountain‘ by Nan Shepherd [1893-1981] which a review in the Guardian newspaper described as ‘The finest book ever written on nature and landscape in Britain’.  It is an account of the author’s journeys in the Cairngorm mountains of Scotland.  Although it is  short, only 108 pages, I have to admit that it did not resonate with me and I did not finish it.  However, I did enjoy the Introduction by Robert MacFarlane and the Afterword by Jeanette Winterson, which together make up about a third of the book. MacFarlane draws parallels between Shepherd’s writing and one of her contemporaries, the French philosopher,  Maurice Merleau-Ponty [1908-1961] who was a leading proponent of existentialism and phenomenology.  Existentialists believe that the nature of our existence is based on our experiences, not just what we think but what we do and feel; while phenomenology is about the connections between experience and consciousness.  Echoing Shepherd and in the spirit of Merleau-Ponty, MacFarlane wrote in 2011 in his introduction that ‘we have come increasingly to forget that our minds are shaped by the bodily experience of being in the world’.  It made me think that as the COVID-19 pandemic pushes most university teaching on-line we need to remember that sitting at a computer screen day after day in the same room will shape the mind rather differently to the diverse experiences of the university education of previous generations.  I find it hard to imagine how we can develop the minds of the next generation of engineers and scientists without providing them with real, as opposed to virtual, experiences in the field, design studio, workshop and laboratory.
