2024 = 2³+3³+4³+5³+6³+7³+8³+9³
And for next year we'll have the entire sum of cubes from 1 to 9!

@mretka Trust but verify ...
julia> sum((1:9).^3)
2025
@mretka And, by a known equality, also
2025 = (1+2+3+4+5+6+7+8+9)²
(The equality can be stated as "the sum of the cubes of the integers in a range starting from 0 or 1 is the square of the sum of the same integers")
@mretka
Also, starting in 2025, pi will be exactly equal to 3 :blobupsidedown:
