The limits of computation were defined before computers even existed

In short: In 1936, Alan Turing theorized the fundamental boundaries of what any computer can achieve. This archival clip explores how those century-old principles still govern today's most sophisticated supercomputers.

Computer scientist Benedict Nixon demonstrates that modern technology remains bound by Turing’s theoretical framework. Using a custom-built variation of simple Turing Machines, Nixon illustrates how these concepts translate from abstract math into physical reality.

The video highlights the Atlas computer at London University as a prime example of a sophisticated machine operating under Turing's guiding principles. It serves as a bridge between 1930s mathematical theory and the practical evolution of computing.
