This guide focuses on dealing with information on metals, non-metals, metal processing and material testing. All of this information is relevant in the mechanical engineering field. This title is learner-centred and the information is presented in a practical, clear and logical way. There are numerous illustrations to explain concepts.

Engineering graphics and design applies itself to a wide field of engineering technologies. This guide deals with drawing, isometric drawing, assembly drawing, detail drawing as well as the use of CAD. The text is learner-friendly and uses simple language. It is logically set out and the text is supported by illustrated clear, accurate diagrams.

The calculus of relations has been an important component of the development of logic and algebra since the middle of the nineteenth century, when Augustus De Morgan observed that since a horse is an animal we should be able to infer that the head of a horse is the head of an animal. For this, Aristotelian syllogistic does not suffice: We require relational reasoning. George Boole, in his Mathematical Analysis of Logic of 1847, initiated the treatment of logic as part of mathematics, specifically as part of algebra. Quite the opposite conviction was put forward early this century by Bertrand Russell and Alfred North Whitehead in their Principia Mathematica (1910 - 1913): that mathematics was essentially grounded in logic. Logic thus developed in two streams. On the one hand algebraic logic, in which the calculus of relations played a particularly prominent part, was taken up from Boole by Charles Sanders Peirce, who wished to do for the "calculus of relatives" what Boole had done for the calculus of sets. Peirce's work was in turn taken up by Schroder in his Algebra und Logik der Relative of 1895 (the third part of a massive work on the algebra of logic). Schroder's work, however, lay dormant for more than 40 years, until revived by Alfred Tarski in his seminal paper "On the calculus of binary relations" of 1941 (actually his presidential address to the Association for Symbolic Logic).

What is the role of a university in society? In this innovative book, Chris Brink offers the timely reminder that it should have social purpose, as well as achieve academic excellence. He book shows how universities can - and should - respond to societal challenges and promote positive social change.

Over the past few years, issues relating to the future of Afrikaans as a tertiary teaching language, and in particular the language policy at Stellenbosch University, have drawn considerable attention and even stirred up controversy. There are many different viewpoints on what role Stellenbosch University is playing and should be playing in the future of Afrikaans. In No Lesser Place gives an overview of and commentary on the main arguments of the taaldebat. The author does so against the background of the historical and current position of Afrikaans at Stellenbosch and also outlines his own position in this regard.
