After five months of posting monthly, I cannot resist the temptation to slip in an extra one.  Mainly because I want to let you know about the Pint of Science Festival taking place next week.  In Liverpool we have organised a series of three evenings at the Philharmonic pub on Hope Street featuring talks by engineers from the School of Engineering and the Institute for Digital Engineering and Autonomous Systems (IDEAS) at the University of Liverpool.  I am planning to talk about digital twins – what they are, how we can use them, what they might become and whether we are already part of a digital world.  If you enjoyed reading my posts on ‘Digital twins that thrive in the real world’, ‘Dressing up your digital twin’, and ‘Are we in a simulation?’ then come and discuss digital twins with me in person.  My talk is part of a programme on Digital with Everything on May 15^th.  On May 13^th and 14^th we have programmes on Engineering in Nature and Science of Vision, Colliders and Crashes, respectively.  I hope you can come and join us in the real-world.
