<human>:  Where does the ‘Turing’ part come from in the name of Turing’s universal machine?
<bot>: The Turing machine is named after Alan Turing, who was the first to formalize the concept of a universal machine. A universal machine is a machine that can simulate any other machine. For example, a Turing machine can simulate a Turing machine, a Turing machine can simulate a Turing machine, and so on.
