It was a real pleasure for me to get the opportunity to give a 2nd talk at UCL on April 17th on the subject of Turing's code breaking and computation by natural systems. The night was organised with the help of Cindy Regalado of UCL, of 'Science has no Borders'. Join her meetup if you want to come along to these and other events. I really appreciated the insightful comments and questions from the audience. You can view the talk on youtube directly here. Or just play below.
