The Harwell Dekatron, a seemingly simple computer, played a pivotal role in one of science’s most groundbreaking discoveries: the structure of DNA. Developed in the UK during World War II, this electromechanical marvel possessed a unique system of rotating drums to store and process information. While considered primitive by today’s standards, the Harwell Dekatron’s ability to rapidly perform complex calculations proved invaluable to James Watson and Francis Crick. They utilized the Dekatron’s processing power to analyze vast amounts of data from X-ray diffraction images of DNA, ultimately leading to their revolutionary double helix model in 1953. The Harwell Dekatron’s contribution highlights the power of even early computers in driving scientific progress. Their calculations unlocked the secrets of life’s blueprint, forever changing our understanding of biology.

Prompt:
