please use small words and the present tense

I subscribe to a game-development algorithms list, the messages of which typically bounce right off my minimal mathematical skills. An example, if you will permit:

A linear transformation T, from a vector-space to itself, need not have a non-zero null-space (ie, it is not injective), or it might not be onto (it, it is not surjective; the range of T does not equal the codomain itself).

Yes, exactly so. Sometimes there are discussions on topics other than computational geometry and the sorts of manipulations to which a gentleman does not subject a matrix, and when that happens I’m glad to contribute what little I can.

Anyway, this week a message floated by which drew my attention to a great page “about the perception of colour”:, and I thought I’d share it with you. I haven’t had time to read it all, but what I did get through I found to be fascinating. Perhaps you will also find it fascinating, which would be a sweet reward indeed for reading another handful of paragraphs of my questionable prose.

    This is another great document on perception of colour, etc.:
