Elements of Logic via Numbers and Sets by D. L. Johnson
English | PDF | 1998 | 179 Pages | ISBN : 3540761233 | 11.2 MB
In mathematics we are interested in why a particular formula is true. Intuition and statistical evidence are insufficient, so we need to construct a formal logical proof. The purpose of this book is to describe why such proofs are important, what they are made of, how to recognize valid ones, how to distinguish different kinds, and how to construct them. This book is written for 1st year students with no previous experience of formulating proofs.

Heinz Kurz, Jeremiah Riemer, "Economic Thought: A Brief History"
English | 2017 | pages: 220 | ISBN: 0231172591, 0231172583 | PDF | 2,5 mb
In this concise yet comprehensive history, Heinz D. Kurz traces the long arc of economic thought from its emergence in ancient Greece to its systematic presentation among the classical thinkers of the late eighteenth and early nineteenth centuries to the influential work of scholars such as Paul Samuelson and Kenneth J. Arrow. With a keen eye for how economic insights are acquired, lost, and reborn, Kurz focuses on the dynamic individuals who give old ideas new life and the historical events that provoke different approaches and theories.
