A note on Turing's 1936

Abstract: To a close reading of the original Turing article of 1936, we can learn it is based on the claim to have defined a number which is not computable, arguing that there can be no machine computing the diagonal on the enumeration of the computable sequences. This article carefully analyses the original 1936 argument, displaying how it cannot be considered a demonstration, and that there is indeed no evidence of such a defined number that is not computable.
