Wolfang Nolting

This textbook offers a clear and comprehensive introduction to analytical mechanics, one of the core components of undergraduate physics courses. The book starts with a thorough introduction into Lagrangian mechanics, detailing the d’Alembert principle, Hamilton’s principle and conservation laws. It continues with an in-depth explanation of Hamiltonian mechanics, illustrated by canonical and Legendre transformation, the generalization to quantum mechanics through Poisson brackets and all relevant variational principles. Finally, the Hamilton-Jacobi theory and the transition to wave mechanics are presented in detail.

Il libro che avete in mano è nato un giorno aprendo i cassetti di un carrello delle emergenze , da lì mi sono spinto più in là, a cercare la storia degli oggetti in esso contenuti, di come essi siano arrivati fino a noi e dei pionieri che li hanno scoperti. Ne è nata una straordinaria e poetica avventura nella Storia della Medicina, fatta strizzando un po’ l’occhio alla Medicina d’Emergenza, una branca medica che mi ha sempre appassionato.

Among the Spanish sources from the first third of the seventeenth century, the Cancionero de la Sablonara holds a very special place. It was prepared between 1625 and 1626 for a German noble, Wolfang Wilhelm, who held, among other titles of nobility, those of count palatine and duke of Neoburg and who had visited the court in Madrid between October 1624 and May 1625. This aristocratic music lover showed enthusiasm for the secular vocal music he heard at the court and, at the end of his trip, requested an anthology for his personal pleasure; it was compiled and copied with great care and beautiful calligraphy by Claudio de la Sablonara, main scriptor—copyist—of the Royal Chapel. The collection contains seventy-five pieces, including “the best songs that are sung in this court,” according to the compiler. This important source, preserved at Munich’s Bayerische Staatsbibliothek, features poems in Spanish and Italian metric forms. There are fewer examples of the latter: merely eight compositions written in liras [six-verse stanzas] and one sonnet.
