+# Dynamically Generating Atoms
+
+> Atoms are constants where their name is their own value.
+
+The use of atoms like `:ok` and `:error` show up all over the place in
+Elixir. These are atoms that tend to be statically defined. Atoms can also
+be dynamically defined using string interpolation.
+
+For example, I can generate a handful of atoms by mapping over a range of
+integers.
+
+```elixir
+> Enum.map(1..5, &(:"some_atom_#{&1}"))
+[:some_atom_1, :some_atom_2, :some_atom_3, :some_atom_4, :some_atom_5]
+```
