A page from \u201cA Million Random Digits \u2026<\/em>\u201d, showing the five-digit sequential line number at left, followed by ten columns of five random digits each<\/figcaption><\/figure>\n\n\n\n

In 1955, military-industrial complex stalwarts RAND Corporation<\/a> published a huge book of just pages and pages of \u2026 digits. The digits were deliberately as random as possible, and were intended to help the fledgling practice of data science carry out truly random simulations. The book was called \u201cA Million Random Digits with 100,000 Normal Deviates<\/a>\u201d. It was also made available on punched cards<\/a>, with 50 digits to a card adding up to ten boxes of 2000 cards. A single box of punched cards was about 370 \u00d7 200 \u00d7 95 mm and weighed roughly 5 kg, so these digits had heft.<\/p>\n\n\n\n

I thought it might be fun (or perhaps fun?<\/sup><\/em>: pronounced with a rising, questioning tone to stress the might<\/em>-ness of any enjoyment arising) to dig into how RAND carried out this work, create some electronics to produce a similar random stream, and see how my random digits compare for randomness with RAND’s. For a final trick, I might even typeset the whole giant table into a book that no-one wants.<\/p>\n\n\n\n

As I research and progress with this project, I’ll add in links here<\/p>\n\n\n\n

I must stress: there is no reason for me to do this<\/strong>. A $5 micro-controller board<\/a> can generate tens to hundreds of thousands of truly random digits per second. Any results I produce will have no use beyond my own amusement.<\/p>\n\n\n\n
