In return, I have some tips for you. If you are curious about the funny looking designs at the upper-left corner, all the designs follow a common motif. The lush, calligraphic flourishes of theory are set against the rational, geometric forms of praxis, and their combination is expressed in the bra-ket notation of quantum mechanics. A linear functional〈f| (bra) acts on a complex vector |v〉(ket) to create〈f|v〉(bra-ket) Like theory and praxis, the spaces of bra’s and ket’s are dual spaces—both entangled with and separate from each other—destined to recombine in profound ways.


Main | The duality of two single quotes—left and right— a rounded ink dot in the vague shape of an epsilon, and a sans-serif shape suggestive of a p for praxis.
