at King’s College, Cambridge and was made a Fellow at only 22. In 1936 Turing, aged 24, published On Computable Numbers and their Application to the Entscheidungsproblem, not a snappy title, but one of the most influential mathematical works of the 20" century. The paper described the new the science of computing and

’s Chinese Room, this is the same process the man in the room followed: get a symbol, look it up in a book, and reply with the corresponding symbol. Universal Turing Machine We have missed one important step from our explanation of the modern computer: the ability to run programs. Nowadays, we take for granted you can do

e. Turing contributed a fundamental model of computation—now known as a Turing Machine—in his paper “On Computable Numbers with an Application to the Entscheidungsproblem,” written and revised in 1936 and published in 1937. In these machines, a linear tape of symbols from a finite alphabet encodes the input for a compu

ifferent machine was required for each separate computational problem; later work by others would show that in one particular machine, now known as a Universal Turing Machine, an arbitrary set of computing instructions could be encoded on that same tape. In the 1940s, von Neumann developed an abstract self-reproducing mac
