Hi, Dan Bach here, lifelong math nut. I'm a retired college math teacher, and current interactive book author / 3D math artist. In my spare moments I watch a lot of NBA basketball and go on long distance runs, but not at the same time. Students convinced me my calculus pictures could be called art. My work gets viewers to look, think, notice, and wonder. And hopefully say, 'That's cool! That's math?'more
