Join two ufology researchers as they stare into the cold, black eyes of alien visitors—those little Gray bastards who are omnipresent in our daily lives. Watch the skies! Grays secretly reveal their outrageous spacecraft to selected, awestruck witnesses. Watch your bedrooms! Grays materialize silently beside beds to abduct paralyzed victims. Every aspect of human life is impacted by their incessant presence, from genes of the individual to the fate of humanity.

Discover specific aspects of the alien menace, including abductions; communications through artists; interconnections between Grays, ghosts, and other paranormal phenomena; and a history of alien attacks on humans. What emerges is a strange, often terrifying, glimpse into the machinations of the Gray aliens as they lurk at the fringes of human consciousness. Read with caution!

The Logical Reasoning with Diagrams and Sentences courseware package teaches the principles of analytical reasoning and proof construction using a carefully crafted combination of textbook, desktop, and online materials. This package is sure to be an essential resource in a range of courses incorporating logical reasoning, including formal linguistics, philosophy, mathematics, and computer science. Unlike traditional formal treatments of reasoning, this package uses both graphical and sentential representations to reflect common situations in everyday reasoning where information is expressed in many forms, such as finding your way to a location using a map and an address. It also teaches students how to construct and check the logical validity of a variety of proofs of consequence and non-consequence, consistency and inconsistency, and independence using an intuitive proof system which extends standard proof treatments with sentential, graphical, and heterogeneous inference rules, allowing students to focus on proof content rather than syntactic structure. Building upon the widely used Tarski's World and Language, Proof and Logic courseware packages, Logical Reasoning with Diagrams and Sentences contains more than three hundred exercises, most of which can be assessed by the Grade Grinder online assessment service; is supported by an extensive website through which students and instructors can access online video lectures by the authors; and allows instructors to create their own exercises and assess their students' work.Logical Reasoning with Diagrams and Sentences is an expanded revision of the Hyperproof courseware package.
