Ohhhhhhhhhhh! I just found out about these things! They are so cool! Anyone else know what a quaternion is, before you go and look it up on the internet? Apart from fractals, can anyone think of a use for them? Here is a link to a page with a description of them if you are two lazy too look. It is primarily for Acadeca students but it is a good definition. Here.

Does no one delight in the beatiful simplicity of the quaternion? What is this world coming to?

I seem to recall quaternions being useful in robotics, particularly in planning how to move jointed robotic arms.

I remember using these a lot in Calc III. Back then we just used them for calculating angles and vectors for problems.

They came up again in real application in my fluid dynamics class. We would get a description of the flow of a Newtonian fluid in that type of format.

i think i am frightened... the day he posted this, i happened to be helping my former high school's acadec team with math... guess what we came across...

I just enjoyed being shown an example of non-comutative vectorial space. And i also enjoyed the complexification and decomplexification of vectorial spaces.

Anyway, my point is that for someone who loves math, there is no need for the "what's it good for" question to be asked...
