Nuclear physics is the branch of physics concerned with the nucleus of atoms. The science is one of Jade Harley's interests and both she and her Grandpa seem to dabble in it. An atom symbol is located in many places in their home and it's one of the most common shirt designs Jade wears.

The Skyship Base that the Wayward Vagabond uses also appears to run on nuclear power; both uranium and atom motifs are seen in it.

An atom is also featured in Skaianet's logo.
