The Turing Machine
Captions available
The idea
A Turing machine is an abstract model of computation in three parts: a memory bank for data, an instruction table of basic operations, and a program counter tracking the current one.
In practice
A paper construction from another century still describes the machines running today.
Where people slip
Abstract is the point — the model outlives machines.
