A liberal engineering education

115-1547_IMGFredrik Sjoberg points out how the lives of Darwin and Linnaeus have become models for generations of natural scientists.  Youthful travels followed by years of patient, narrowly focussed research and finally the revolutionary ideas and great books.  Very many scientists have followed the first two steps but missed out on the last one, leaving them trapped in ‘the tunnel vision of specialised research’.  As our society and its accompanying technology has become more complex, more and more tunnels or silos of specialised knowledge and research have been created.  This has led specialists to focus on solving issues that they understand best and communicating little or not at all with others in related fields.  At the same time, our society and technologies are becoming more interconnected, making it more appropriate to cross the cultural divides between specialisms.

One of the pleasures of teaching my current MOOC is the diversity of learners in terms of gender, geography and educational background who are willing to cross the cultural divides.  We have people following the MOOC in places as diverse as Iceland, Mexico, Nigeria and Syria.  We have coffee bean growers, retired humanities academics, physical chemists and social historians.  In most of the western world, engineering is taught to male-dominated classes and this has remained a stubborn constant despite strenous efforts to bring about change.  So it is a pleasure to interact with such a diverse cohort of people seeking to liberate their minds from habit and convention.

The original meaning of the term ‘liberal studies’ was studies that liberated students’ minds from habit and convention.  Recently, Vinod Khosla has suggested that we should focus on teaching our students ‘liberal sciences’.     This seems to connect with the ’emotive traits’ that David Brooks has proposed will be required for success in the future, when machines can do most of what humans do now (see my post entitled ‘Smart Machines‘ on February 26th, 2014).  These emotive traits are a voracious lust of understanding, an enthusiasm for work, the ability to grasp the gist and an empathetic sensitivity for what will attract attention.   We don’t teach much of any of these in traditional engineering degrees which is perhaps why we can’t recruit a more diverse student population.  We need to incorporate them into our degree programmes, reduce much of the esoteric brain-twisting analysis and encourage our students to grapple with concepts and their broader implications.  This would become a liberal engineering education.

Converting wealth into knowledge and back to wealth

1 Reply

Some months ago I was invited to give the opening lecture at a workshop in China on connecting science and business in the field of experimental mechanics. ‘Connecting science and business’ was the sub-title of a book I wrote with Bob Handscombe some years ago and ‘experimental mechanics’ is a theme that runs deep through my research. So, I felt honored to be invited and confident that I had something relevant to say. However, probably the most succinct statement at the workshop was made by Professor Jian Lu from City University of Hong Kong quoting Geoffrey Nicholson, the inventor of Post-Its: ‘Research is the transformation of money into knowledge. Innovation is the transformation of knowledge back into money creating value.’

The central role that money plays in life is acknowledged in the saying ‘money makes the world go around’. However, the intertwining of money and knowledge is less widely recognised. Although we talk about a knowledge economy not many people understand what it means or how it functions. The diagram below is an attempt to show how research leads to the creation of private information which needs to be disseminated in order to become public information. Public information becomes public knowledge when it is incorporated into our structured, shared understanding through study and learning. Public knowledge is used in innovation processes to create new technology and wealth, which fuels further research, so that there is a feedback loop.  The diagram is modified from one by Max Tegmark‘s book ‘Our Mathematical Universe‘ and, of course is simplified, perhaps too much, but nevertheless illustrates the process of knowledge creation even if sometimes the whole process functions inside an organisation. In the later situation, the creation of knowledge and the benefits to society are likely to be impeded, at least temporarily.

From Russell to Schrodinger on thinking contradictions

3 Replies

galleyhead lighthouse‘People would rather die than think and most people do’ is a witticism attributed to Bertrand Russell. If this is true then the prospects are poor for the societal conversation on the morality of organizations that I suggested a few months ago, since it requires people to think for themselves. Socrates ran into trouble when he advocated such an approach; so, perhaps I should be careful about what I suggest and return to the silent majority. Now I have contradicted myself, but as Erwin Schrödinger wrote ‘If a man never contradicts himself, the reason must be that he virtually never says anything at all’. I am sure that I have contradicted myself many times in my posts over the last year but you continue to read this blog in increasing numbers [up by 50% compared to 2014]. Thank you for your support during 2015.

Happy New Year!

Connecting robotic touch and vision

Leave a reply

katherine kuchenbeckerSome months ago I wrote about soft robots that could delicately pick up fragile objects [see my post entitled ‘Robots with a delicate touch’ on June 3rd, 2015]. These robots, developed by George Whiteside’s research group, went some way towards mimicking the function of our hands.  However, these robots are numb because they have no sense of touch.  Think about how hard it would be to strike a match or pick up an egg without your sense of touch. Katherine Kuchenbecker from the University of Pennsylvania is working on robots with tactile sensors that detect pressure and vibrations.  This sensitivity transforms their ability to perform delicate tasks such as picking up an egg, or perhaps more significantly perform surgery.  I listened to Professor Kuchenberger speak at a meeting at the Royal Society on ‘Robotics and Autonomous Systems’ where she put us off our lunch with some gory videos on robot-assisted surgery. You can watch them at her website. Her vision is of robots that connect vision and touch, which is of course what we do effortlessly most of the time.
