Smolder: “Maths and Stuff”

Yona: What Dragon mean?

Smolder: *points* Her book. “Maths and Stuff”. Sounds like a very generalised book to have such an…. advanced topic inside.

Gallus: Yeah, Kinda like having a book about colouring with a section on light refraction through prisms…

Ocellus: Light refraction? Since when were you studying physics?

Gallus: Since I realised that there are an awful lot of objects in Equestria which enjoy landing on me.

Sandbar: Not to mention, defying the laws of physics

Silverstream: Discord?

Sandbar: *nods sagely* Discord
