We discuss combining physical experiments with machine computations and intro- duce a form of analogue-digital Turing machine. We examine in detail a case study where an experimental procedure based on Newtonian kinematics is combined with a class of Turing machines. Three forms of analogue-digital machine are studied, in which physical parameters can be set exactly and approximately. Using non-uniform com- plexity theory, and some probability, we prove theorems that show that these machines can compute more than classical Turing machines.
