A Brownian Turing machine includes a multiplicity of alphabet elements, multiple state transition elements and a single enzymatic unit. The alphabet elements define a plurality of different types of information. The state transition elements define how the machine can change state. The enzymatic unit receives dimers one at a time, wherein each dimer is comprised of one state transition element combined to one alphabet element. The enzymatic unit determines if a dimer is an allowable next dimer and, if it is, connects the state transition element of the allowed dimer to a history tape of the history of at least one change of state. The enzymatic unit also modifies an alphabet tape, comprising at least two alphabet elements connected together, with the alphabet element of the allowed dimer in accordance with the state transition defined by the state transition element of the allowed dimer. The alphabet elements, state transition elements and enzymatic unit can be mechanical, chemical or biological elements.
