Hardly, though you may have the impression.
Proof: You cannot understand that the function f(10n) = n from D = {10n
| n ∈ ℕ} to ℕ = {1, 2, 3, ...} is not a bijection because for every
initial segment {1, 2, 3, ..., n} of ℕ there are too few numbers of the
form 10n that can be paired with numbers n.
Wow. For every segment there are numbers {10, 20, …, 10n}.
But for every segments more are needed: {1, 2, 3, ..., 10n}
