What is Equidistribution modulo 1?

Imagine you're sharing candies with your friends, but not just any candies: you're taking a big pile and giving each friend a little piece from it one by one, over and over again.

That’s what equidistribution modulo 1 is like, but instead of candies, we’re talking about numbers!

What does "modulo 1" mean?

Think of it like this: when you divide a number by 1, the leftover part (the fraction) is all that matters. For example:

  • If you have 2.5, modulo 1 gives you 0.5
  • If you have 3.9, modulo 1 gives you 0.9

So we're just looking at those little fractions, like the part of a candy that's left after you’ve shared it with your friends.

What is "equidistribution"?

It means that as you keep giving out pieces (or numbers), the leftover parts spread out evenly across all possible values between 0 and 1, like sprinkles on cake, no clumps, no gaps! Imagine you're sharing candies with your friends, but not just any candies: you're taking a big pile and giving each friend a little piece from it one by one, over and over again.
