On the trustworthiness of multi-physics models

I stayed in Sheffield city centre a few weeks ago and walked past the standard measures in the photograph on my way to speak at a workshop.  In the past, when the cutlery and tool-making industry in Sheffield was focussed around small workshops, or little mesters, as they were known, these standards would have been used to check the tools being manufactured.  A few hundred years later, the range of standards in existence has extended far beyond the weights and measures where it started, and now includes standards for processes and artefacts as well as for measurements.  The process of validating computational models of engineering infrastructure is moving slowly towards establishing an internationally recognised standard [see two of my earliest posts: ‘Model validation‘ on September 18th, 2012 and ‘Setting standards‘ on January 29th, 2014].  We have guidelines that recommend approaches for different parts of the validation process [see ‘Setting standards‘ on January 29th, 2014]; however, many types of computational model present significant challenges when establishing their reliability [see ‘Spatial-temporal models of protein structures‘ on March 27th, 2019].  Under the auspices of the MOTIVATE project, we are gathering experts in Zurich on November 5th, 2019 to discuss the challenges of validating multi-physics models, establishing credibility and the future use of data from experiments.  It is the fourth in a series of workshops held previously in Shanghai, London and Munich.  For more information and to register follow this link. Come and join our discussions in one of my favourite cities where we will be following ‘In Einstein’s footprints‘ [posted on February 27th, 2019].

Engineering as the very spirit and soul of your existence

I wrote some weeks ago about art challenging the way we think and artists being spokespeople for society [see ‘Spokesperson for society’ on August 28th, 2019] and also about ‘Taking a sketch instead of snapping a photo’ [on September 3rd, 2019].  My photo of the sketch taken by Rennie Mackintosh was snapped at an exhibition in Walker Art Gallery in Liverpool; and, on the wall of the gallery was a quote from Rennie Mackintosh: ‘All artists know that pleasure derivable from their work is their life’s pleasure – the very spirit and soul of their existence’.  I feel the same way about my work as an engineer and I think that many of my colleagues would agree with me.  In my welcome talk to new engineering undergraduate students last week, I used this quote and tried to convey the extent to which science and engineering is a part of my existence and how I hoped it would become a part of their life.  I am not sure that I convinced very many of them.

Taking a sketch instead of snapping a photo

We are lucky to live in a house with a great view of Liverpool cathedral [see picture in ‘Two for one‘ on January 2nd, 2019].  Hundreds of tourists visit every day and take pictures of the cathedral with their smart phones.  A few even turn around and take a picture of our house!  It is a modern disease: capturing pictures of a spectacle without actually looking at it and then probably never looking at the photograph.  There is some small level of fulfilment in having taken the photograph; however, 120 years ago there were fewer tourists and they had no cameras.  Instead, when Charles Rennie MackIntosh visited Naples on April 8th, 1891, he admired the tower of the Church of Santa Maria del Carmine and ‘took a sketch’.  It must have taken him some time and concentrated effort.  The level of pleasure and fulfilment from taking a sketch must have been much greater than from our modern experience of snapping a photo.

Of course, there was no Liverpool Cathedral in 1891 and ten years later, Rennie Mackintosh was disappointed that his proposals for it were not selected from the 103 submitted.

Spokesperson for society

There is an excellent exhibition of Keith Haring’s work at the Tate Liverpool until November 2019.  Keith Haring and I were born a couple of years apart but that’s where the similarity ends.  He was an American artist who collaborated with the likes of Andy Warhol and Jean-Michel Basquiat and was influenced by Pablo Picasso, Walt Disney and Dr Seuss.  He was part of the New York street culture of the 1980s and many of his early works were forms of graffiti painted in subways and on the sides of buildings.  Some people think that art should challenge the way you think about the things; however, “Haring felt that the artist is ‘spokesman for a society at any given point in history’ whose visual vocabulary is determined by their perception of the world”.  His work about racism, the excesses of capitalism and the misuse of religion for oppressive purposes seem as relevant today as thirty years ago.
