Computational Equivalence and Turing Completeness

Given unlimited time and memory, any computing device—from supercomputers to smartphones—can execute the same set of tasks, differing only in speed and resources, because a system that can simulate a Turing machine is Turing‑equivalent, making all Turing‑complete languages capable of solving any computable problem, with only efficiency or code length varying.

What Are Cellular Automata? History, Types, and Their Computational Power

Cellular automata are discrete computational models used across physics, biology, and computer science, featuring grids of cells with simple rules that can produce complex behavior, classified into four Wolfram classes, with a rich history from Ulam and von Neumann to modern research.
