What a difference a day makes

Schnirelmann density

At last... a tool to measure the density of a sequence. Shnirelmann density. Will it help? Maybe, maybe. What caused my fascination for mathematics, in the first place? It must have been Spirograph.

Quaternions...!

This book attempts to teach you what an average math student learns in three years ( or more ). I suppose the difference between the bookreader and the student is that the bookreader has a bag full of tricks applicable for game coding while the mathematician has a configurable toolbox applicable almost in any field. The average Linear Algebra course takes a year. In this book? A few chapters, I suppose. All in all an excellent introductory math book with focus. The Final Test...Is the code for these amazing grativity balls somewhere in that book? Yep!
