I am still not sure I understand using 4x4 matrices to do transforms in three space. I can write the code though (slowly).
Because a 3 dimensional object can be translated by a linear operation in 4 dimensional space. Similar to how you are able to move (the projection) of a 2D shape by moving it along an arbitrary third axis pointing out of the shape's plane. This doesn't sound fundamentally very difficult for me. Now group theory on the other hand... I guess it depends on how your brain works. I have a lot less trouble with geometry than with more abstract maths.
I figure that if I feel a need to consult my old BioChem text to figure out just what that ingredient is, I shouldn't be eating it.
Though I think this is a wise attitude, you must be starving!? Or do you grow your own groceries or something?

There, fixed that for you.
then why not tax per volume traded?
It *is* taxed per volume. 0.03%, which it nothing for a normal transaction. But for someone who buys and sells the same stock a hundred times per day, just to profit from tiny fluctuations in the stock value, it's 3%. This will kill the ridiculous business of racing for fastest connection and smartest trading algo, which is *good* because it is a ridiculous and useless business.
