Turillo Ristori Togna
Exercises in the Bath. The Togna System of Home Gymnastics to Promote Health, Prevent Diseases and Prolong Life
In 16 (cm 13,5 x 20), pp. XIII + (2) + 123 + (6) con 7 tavole fuori testo con riproduzioni fotografiche al recto e al verso per un totale di 54 immagini raffiguranti l'Autore che compie esercizi ginnici dentro la vasca da bagno, 1 tavola fuori testo con ritratto fotografico dell'Autore. Legatura editoriale in cartone con illustrazione in nero di una vasca da bagno al piatto anteriore. Alcune abrasioni al margine superiore del piatto anteriore e residui di inchiostro nero da pressione sulla copertina di fogli con testi a stampa. Conservate all'interno due schede editoriali - con testo differente - di promozione del volume. Curiosa e poco comune pubblicazione in cui l'A. si fa portavoce di un metodo di educazione fisica che consiste nel compiere esercizi immersi dal collo in giu' nell'acqua della vasca da bagno. Si promettono risultati favorevoli e benefici per l'organismo e per alcune problematiche come l'insonnia, le vene varicose, l'obesita', la costipazione, la pressione alta, gli attacchi di nervi. Non datato ma 1938.

The price clipped dust jacket has several edge tears nicks a couple of medium sized chips and some generalized rubbing to the paper. This book contains a number of papers by Herbert E. Ives who did not believe that Einstein's Theory of Relativity was correct - he proceeded to perform experiments which would prove his hypothesis -- and in the process actually proved though he believed otherwise that the "relativistic time dilation to the Doppler shift of light" Einstein theorized was indeed correct. this experiment is known as the "IvesStilwell experiment". This book includes letters to physicists his own notes experiments etc. from and to Ives regarding his somewhat obsessive idea that Einstein's Theories were incorrect. This book is somewhat scarce. .

La Matière & la Force. La force. Deux Conférences de M. Le Professeur John Tyndall. Traduites en francais et suivies d'une dissertation sur l'essence de la matière, la constitution des corps et la synthèse des phénomènes physique par l'Abbé Moigno.
Chez Gautir – Villars Imprimeur – Libraire, Paris, s. d. (ma 1875 circa). In 12esimo, pp. 74 (con la Table des Matières), bross. edit. in carta verde. John Tyndall (Leighlin Bridge, 1820 – Hindhead, 1893) è stato un fisico irlandese. Si laureò solo nel 1850, in quanto esercitò per alcuni anni la professione di geometra e ingegnere. Professore alla Royal Institution di Londra, divenne ben presto amico di Michel Faraday. Per le sue ricerche di ottica sull'azzurro del cielo, sul calore e sulla propagazione del suono fu nominato membro della Royal Society. Fu il primo scienziato a dimostrare sperimentalmente l'esistenza dell' effetto serra. Di grande interesse è il fenomeno che va sotto il nome di "effetto Tyndall": illuminando con un pennello di luce un mezzo torbido, il percorso del pennello può essere osservato da una posizione laterale; in modo analogo si verifica quando un sottile fascio di luce attraversa una stanza buia o in penombra, nella cui atmosfera sia sospeso del pulviscolo. Questo effetto è di grande importanza nello studio delle sostanze colloidali. Oltre che per le sue ricerche, Tyndall è noto anche per essere stato un grande maestro nella didattica dell'insegnamento della fisica: per rendere semplici e facilmente comprensibili gli argomenti scientifici ideò, fra l'altro, semplici esperimenti scolastici, alcuni dei quali sono tuttora impiegati nelle scuole. Vari suoi scritti costituiscono ancora oggi dei modelli per l'insegnamento e la divulgazione della fisica, conservando il rigore scientifico.Tyndall aveva anche una passione molto forte per la montagna, ed è stato uno dei grandi esploratori delle Alpi nella fase pionieristica di metà ottocento. Sua è la prima ascensione del Weisshorn (4506 m.), nel Vallese, e la via da lui trovata lungo la cresta est nel 1861 è ancora oggi considerata la via normale alla vetta di questo gigante alpino. Ex Libris Giovanni Castellana. Normali mancanze alla carta del dorso e minimi segni del tempo ma buona conservazione.
