Se è chiaro che rifiuta la concezione aristotelica dei corpi e adotta alcuni aspetti dell’atomismo, diversi testi, in diversi tempi, suggeriscono diversi punti di vista. Ripercorrendo i primi scritti di Galileo e arrivando quindi a delineare il suo ultimo pensiero, l’autore ci dimostra l’unità del pensiero galileiano: una visione della materia che congiunge prospettive fisiche e matematiche insieme. / A long tradition of studies has generally accepted that, after an initial explicit adhesion to Democritus’ physical atomism, Galileo’s concept of matter developed into the mathematical theory of the continuum illustrated in his Discorsi of 1638. The analysis carried out in this volume suggests that these two different interpretative models of the structure of matter were not considered by Galileo as alternative, but co-existed from the very beginning of his intellectual activity and were regarded by him as perfectly equivalent.

Howell Book House 1995, cm.15x23, pp.XVIII,362, paperback. The C Level is an intermediate level of horsemanship. This C Level manual builds on material covered in The United States Pony Club Manual of Horsemanship: Basics for Beginners/D Level. Whether you are a Pony Clubber who has passed the D Level tests or simply a rider who has mastered the same basics, this manual will enable you to increase your skills and teach you what you must know in order to ride independently and correctly with good position, balance, and use of the aids on the flat, over fences, and in the open. At the intermediate level you are expected to take more responsibility for the care and management of your pony, and you will learn how to do this as well. In addition, you will learn the skills needed for conditioning and preparing your pony and yourself for competitions and special events. From the C Level, you may go on to higher Pony Club ratings such as B, H A, or A Ratings, or specialize in such disciplines as dressage, show jumping, eventing, and showing. Or you may just want to have the pleasure of caring for your horse or pony and participating in your favorite riding activities. Either way, The United States Pony Club Manual of Horsemanship: Intermediate Horsemanship/C Level will give you an excellent basis in horsemanship for the lifelong enjoyment of horses and horse sports.
