The full paper was not published until 1828. Stokes's analysis of the internal friction of fluids was published in 1845 and as he was not familiar with the French litterature of mathematical physics he derived independently his own equations which accounts for the double-name of the equations. "The Navier-Stokes equation is now regarded as the universal basis of fluid mechanics no matter how complex and unpredictable the behavior of its solutions may be. It is also known to be the only hydrodynamic equation that is compatible with the isotropy and linearity of the stress-strain relation." Olivier Darrigol."Navier studied the motion of solid and liquid bodies deriving the partial differential equations to which he applied Fourier's methods to find particular solutions. This theoretical research led him to formulate the well-known equation identified with his name and that of Stokes. Navier viewed bodies as made up of particles which are close to each other and which act on each other by means of two opposing forces - one of attraction and one of repulsion - which when in a state of equilibrium cancel each otherout. The repelling force resulted from the caloric that a body possessed. When equilibrium is disturbed in a solid a restoring force acts which is proportional to the change in distance between the particles."DSB X p. 4."The equations are useful because they describe the physics of many things of academic and economic interest. They may be used to model the weather ocean currents water flow in a pipe and air flow around a wing. The Navier-Stokes equations in their full and simplified forms help with the design of aircraft and cars the study of blood flow the design of power stations the analysis of pollution and many other things. Coupled with Maxwell's equations they can be used to model and study magnetohydrodynamics. "Wikipedia. </em> unknown

In-4°, (6 cc), 5-132, 2 tavole, 1 ritr., rilegatura in pelle seicentesca, con titolo al dorso in oro, completo delle due carte della tavola dei contenuti. Prima edizione. I Quesiti di Tartaglia contiene il suo più importante risultato matematico: la scoperta indipendente della regola per risolvere equazioni di terzo grado (cubiche), una regola inizialmente formulata ma non pubblicata da Scipione de Ferro nel primo o nel secondo decennio del XVI secolo. Tartaglia risolse nuovamente il problema nel 1535, ma mantenne i dettagli segreti per molti anni, usando le sue conoscenze per trarre vantaggio dalle frequenti controversie pubbliche tra gli studiosi della sua epoca. Alla fine rivelò la regola a Girolamo Cardano nel 1539 dopo che Cardano giurò di mantenerla segreta, ma sei anni dopo Cardano ruppe la sua promessa pubblicando la regola nella sua Ars magna ... Cardano attribuì sia a Tartaglia che a Ferro la scoperta della regola , ma Tartaglia fu infuriato per la violazione della promessa di Cardano e lo accusò duramente nel libro IX di Quesiti, in cui pubblicò anche la sua versione delle sue ricerche in equazioni di terzo grado. In-4°, (6 cc), 5-132, 2 plates, 1 portr., ,17th century leather binding, with title on the back in gold, complete with the contents table. First edition. Tartaglia's Questions contains his most important mathematical result: the independent discovery of the rule to solve third-degree (cubic) equations, a rule established but not published by Scipione de Ferro in the first or second decade of the sixteenth century. Tartaglia solved the problem again in 1535, but kept the details secret for many years, using his knowledge to take advantage of frequent public controversies between the studies of his time. Eventually he revealed the rule to Girolamo Cardano in 1539 after Cardano swore to keep it secret, but six years later Cardano broke his promise by publishing the rule in his Ars magna ... Cardano attributed both the discovery of the rule to Tartaglia and Ferro, but Tartaglia was infuriated by the violation of Cardano's promise and the accusation harshly in Book IX of Quesiti, in which he also published his version of his research in third-degree equations.
