ARE THERE TWO EXACT DICES?

I Love dice! Why?

Dice are beautiful as an example of good design. My bet is that an alien intelligence would understand their concept faster than many other artifacts they could find if they would land in our beloved and endangered planet. And they would love them as I do! Their form and functionality match so well, that we don’t need too much explanation to use them, and to understand the complex, interesting and metaphysical question they are addressing: is “randomness” real? Or it’s just a word to disguise our incapability to fully explain events from a logical and rational point of view.

Dice are designed to be rolled, so once they land on a surface and stop moving, we can look at their upper surface and get a message. A message that can be in the form of one dot, two dots, three dots, four dots, five dots or six dots. The idea is that we will only know the message, once the die is cast. In theory, this is impossible to know for certain, but this is questionable. According to the general idea of probability, you could get close to make a prediction, based on enough collected data, obtained from rolling the same dice in a similar way of rolling it. But there’s also a concept of each dice roll being a discrete event, meaning that it won't be determined by a previous roll or result. Even if there is a tendency in the die, each roll of the ide is an independent event. There are a lot of subtleties around this problem, that I’m excited to explore. I don’t want to believe blindly in the authority of probability, science or religion. I want to let the dice speak for themselves! And to create a dialogue with the concepts around it that come from probability, religion, physics, metaphysics, mathematics, speculation, and philosophy, among other possible ways of thinking.

How “random” dice are? How random can they be? How can I test them and observe how they are creating what we call “random” results? Can we understand enough to be able to predict the next roll? Can a computer learn how to do this? If so, how accurate can it be? Would it beat us on a gambling session? These are practical questions we can address using technology like electronics, computers and off course, dice! (Which could arguably or poetically be understood as an analog, electricity-less computer or machine).

People, including me, take the word “randomness” for granted. When I roll a die I do it assuming it will give me an unpredictable or “random” outcome. This also happens with the use of computers. And when we use our phone or music player in the Shuffle mode. We want to believe the randomness they produce is “perfect”. But according to Donald Knuth:

“Many random number generators in use today are not very good. There is a tendency for people to avoid learning anything about such subroutines; quite often we find that some old method that is comparatively unsatisfactory has blindly been passed down from one programmer to another, and today’s users have no understanding of its limitations.”

This series of drawings are the starting point of Slow numbers. A project about the nature of randomness, using different methods of “random generation”.

As today, those methods are physical dice, computer algorithms that simulate random outcomes(digital dices), and human simulated dices (people pretending to be dice).

The idea is to also explore alternative new ways to generate what we call random outcomes.

How many drawings will I have to do to make two exact ones?
