Hello have a great new year

[David Bowe]

Yeah I know quaternions are used quite a bit in game programming but I’m not sure what they mean

[SantiagoCortz]

Quaternion is a mathematic concept, that extend complex numbers. It can be used for a lot of things, but its properties are interesting to represent rotation in 3D space. You can express any rotation with a quaternion, and it's less costly to compute than with 4D matrices. 
Check Wikipedia's page, it gives a lot of information about that

They are a representation of 3d rotation that avoids issues relating to gimbal lock and have a bunch of nice properties
