A Numb Derivation

Hi ho hey ho! A NUMB DERIVATION is a graphical novel about Venir Stroka, a peculiar youth obsessed with arthropods & leaves, seawater & railroads, skeletons & blood. It is comprised of 18 short letters, each one being based off of a distant friend, love interest, or ex I no longer talk to, written as a strange attempt to convey some of my most terrible and loathsome fears.

This textbook introduces formal languages and automata theory for upper-level undergraduate or beginning graduate students. While it contains the traditional mathematical development usually employed in computational theory courses, it is also quite different from many of them. Machines, grammars, and algorithms developed as part of a constructive proof are intended to be rendered as programs. The book is divided into four parts that build on each other. Part I reviews fundamental concepts. It introduces programming in FSM and reviews program design. In addition, it reviews essential mathematical background on sets, relations, and reasoning about infinite sets. Part II starts the study of formal languages and automata theory in earnest with regular languages. It first introduces regular expressions and shows how they are used to write programs that generate words in a regular language. Given that regular expressions generate words, it is only natural to ask how a machine can recognize words in a regular language. This leads to the study of deterministic and nondeterministic finite-state machines. Part III starts the exploration of languages that are not regular with context-free languages. It begins with context-free grammars and pushdown automata to generate and recognize context-free languages, and it ends with a discussion of deterministic pushdown automata and illustrates why these automatons are fundamentally different from nondeterministic pushdown automata. Part IV eventually explores languages that are not context-free, known as context-sensitive languages. It starts by discussing the most powerful automaton known to mankind: the Turing machine. It then moves to grammars for context-sensitive languages, and their equivalence with Turing machines is explored. The book ends with a brief chapter introducing complexity theory and explores the question of determining if a solution to a problem is practical.

Deriving is a feminist exploration of the creation of life, of family, and of words themselves. Delisle asks: How does past infertility colour the experience of new motherhood? How do historical voices echo in the present? How does language impact our ways of being in the world? These poems embrace the rich material of mothering with unapologetic honesty, confronting the experiences that some would keep hidden. Fear, anger, envy mix with joy and ultimately hope, as Delisle considers the challenges of conceiving and raising children in both familial and global contexts. Deriving is a poignant, lyrical meditation on longing, place, and embodiment. I watched it freeze up, rafts of white snagging beneath the bridge, frazil ice, pans linked along the shoreline. Inside me my son was building white fat on bone. - from “North Saskatchewan”
