by Ivor Grattan-Guinness One of the distortions in most kinds of history is an imbalance between the study devoted to major figures and to lesser ones, concerning both achievements and influence: the Great Ones may be studied to death while the others are overly ignored and thereby remain underrated. In my own work in the history of mathematics I have noted at least a score of outstanding candidates for neglect, of whom Mario Pieri (1860–1913) is one. A most able contributor to geometry, arithmetic and mathematical analysis, and mat- matical logic during his rather short life, his work and its legacy are not well known. The main reason is that Pieri worked “in the shadow of giants,” to quote one of the authors 1 of this volume. Born into a scholarly family in Lucca, Pieri was educated briefly at the University of Bologna and principally at the prestigious Scuola Normale Superiore, in Pisa; under the influence of Luigi Bianchi (1856–1928) he wrote there his doctoral dissertations on al- braic and differential geometry. During his twenties came appointments in Turin, first at the military academy and then also at the university, where he fell under the sway of Corrado Segre (1863–1924) in algebraic geometry, and Giuseppe Peano (1858–1932) in the foundations of arithmetic, mathematical analysis, and mathematical logic. From 1900 to 1908 he held a chair at the University of Catania before moving to Parma, where he died from cancer.
Even the most hands-on of classic bike enthusiasts will often shy away from working on their bike's electrical system, believing they have neither the skill nor the knowledge for such work. Dr James Smith explains in Classic Motorcycle Electrics Manual that this need not be the case. Starting with basic electrical theory, the book demonstrates a wealth of electrical tips and techniques, providing a progressive and detailed guide to tasks ranging from simple repairs and upgrades, through to completely rewiring a classic motorcycle. Illustrated profusely with full-colour photographs and easy-to-follow wiring diagrams, this book will be an invaluable resource for all classic bike owners and restorers. The book covers: basic electrical theory; correct usage of a multimeter; comprehensive fault-finding techniques; making good electrical connections; fuses and circuit protection; dynamo and alternator charging systems; correct battery selection and maintenance; improving lighting and installing LEDs; selecting the right spark plug, and much more. Fully illustrated with 420 colour photographs and 167 CAD easy-to-follow wiring diagrams, this is an essential reference work for all classic bike owners.
