Francisco de Quevedo (1580–1645), one of the greatest poets of the Spanish Golden Age, was the master of the baroque style known as “conceptismo,” a complex form of expression fueled by elaborate conceits and constant wordplay as well as ethical and philosophical concerns. Although scattered translations of his works have appeared in English, there is currently no comprehensive collection available that samples each of the genres in which Quevedo excelled—metaphysical and moral poetry, grave elegies and moving epitaphs, amorous sonnets and melancholic psalms, playful romances and profane burlesques.In this book, Christopher Johnson gathers together a generous selection of forty-six poems—in bilingual Spanish-English format on facing pages—that highlights the range of Quevedo’s technical expertise and themes.
Johnson’s ingenious solutions to rendering the difficult seventeenth-century Spanish into poetic English will be invaluable to students and scholars of European history, literature, and translation, as well as poetry lovers wishing to reacquaint themselves with an old master.
Torres Quevedo's 1920 electromechanical arithmometer, fully functional but never commercialized, which used a typewriter to send commands and print its results.It has been commonly assumed (see Metropolis and Worlton 1980) that Charles Babbage’s work on a mechanical digital program-controlled computer, which he started in 1835 and pursued off and on until his death in 1871, had been completely forgotten and was only belatedly recognized as a forerunner to the modern digital computer. Ludgate, Torres y Quevedo, and Bush give the lie to this belief, and all made fascinating contributions that deserve to be better known.Torres Quevedo demonstrated twice, in 1914 and in 1920, that all of the cogwheel functions of a calculating machine like that of Babbage could be implemented using electromechanical parts. His 1914 analytical machine used a small memory built with electromagnets; his 1920 machine, built to celebrate the 100th anniversary of the invention of the, used a typewriter to receive its commands and print its results.Torres 1913 paper, 'Essays on Automatics,' also introduced the idea of floating point arithmetic, which historian Randell says was described 'almost casually,' apparently without recognizing the significance of the discovery.Aerostatics. Cable car in Ulia (1916)In 1890 he presented his cableway in, a country very interested in that transport owing to its geography and which was already coming to use cable cars for bulk transport, but Torres's project was dismissed, allowing certain ironic commentary from the Swiss press. In 1907, Torres constructed the first cableway suitable for the public transportation of people, in the in. The problem of safety was solved by means of an ingenious system of multiple support cables.
The resulting design was very strong and perfectly resisted the rupture of one of the support cables. The execution of the project was the responsibility of the Society of Engineering Studies and Works of Bilbao, which successfully constructed other cableways in, and elsewhere.But it is doubtless the in in which has gained the greatest fame in this area of activity, although from a scientific point of view it was not the most important. The cableway of 580 meters in length is an aerial cable car that spans the in the on the Canadian side, constructed between 1914 and 1916, a Spanish project from beginning to end: devised by a Spaniard, constructed by a Spanish company with Spanish capital (The Niagara Spanish Aerocar Co. Limited); a bronze plaque, located on a monolith at the entrance of the access station recalls this fact: Spanish aerial ferry of the Niagara. Leonardo Quevedo Torres (1852–1936).
It was inaugurated in tests on 15 February 1916 and was officially inaugurated on 8 August 1916, opening to the public the following day; the cableway, with small modifications, continues to run to this day, with no accidents worthy of mention, constituting a popular tourist and cinematic attraction. Radio control: the Telekino In 1903, Torres presented the Telekino at the Paris Academy of Science, accompanied by a brief, and making an experimental demonstration. In the same year, he obtained a patent in France, Spain, Great Britain, and the United States.The Telekino consisted of a that executed commands transmitted by electromagnetic waves. It constituted the world's second publicly demonstrated apparatus for radio control, after Nikola Tesla's Patented 'Teleautomaton', and was a pioneer in the field of. In 1906, in the presence of the king and before a great crowd, Torres successfully demonstrated the invention in the, guiding a boat from the shore.
Later, he would try to apply the Telekino to projectiles and torpedoes but had to abandon the project for lack of financing. In 2007, the prestigious (IEEE) dedicated a Milestone in Electrical Engineering and Computing to the Telekino, based on the research work developed at by Prof., who was the driving force behind the Milestone nomination.Analogue calculating machines. The Torres Quevedo building at the Superior Polytechnical Center of the.Analogue calculating machines seek solutions to equations by translating them into physical phenomena. Numbers are represented by physical magnitudes such as may be done with certain rotational axes, potentials, electrical or electromagnetic states, and so on. A mathematical process is thereby transformed by these machines into an operative process of certain physical magnitudes which leads to a physical result corresponding with the sought mathematical solution.
The mathematical problem therefore is solved by a physical model of itself. From the mid 19th century, various such mechanical devices were known, including integrators, multipliers, and so on; it is against this background that Torres's work is defined. He began with a presentation in 1893 at the Academy of Exact, Physical and Natural Sciences of the Memory on algebraic machines. In his time, this was considered an extraordinary success for Spanish scientific production. In 1895 the machines were presented at a congress in Bordeaux.

Later on, in 1900, la Memoria would present the calculating machines at the Paris. These machines examined mathematical and physical analogies that underlay analogue calculation or continuous quantities, and how to establish mechanically the relationships between them, expressed in mathematical formulae. The study included and used the. From a practical standpoint, it showed that mechanisms such as turning disks could be used endlessly with precision, so that variables' variations were limited in both directions.On the practical side, Torres built a whole series of analogue calculating machines, all mechanical. These machines used certain elements known as arithmophores which consisted of a moving part and an index that made it possible to read the quantity according to the position shown thereon.
The aforesaid moving part was a graduated disk or a drum turning on an axis. The angular movements were proportional to the logarithms of the magnitudes to be represented. Using a number of such elements, Torres developed a machine that could solve algebraic equations, even one with eight terms, finding the roots, including the complex ones, with a precision down to thousandths. One part of this machine, called an 'endless spindle' ('fusee sans fin') and consisting of great mechanical complexity, allowed the mechanical expression of the relation y=log(10^x+1), with the aim of extracting the logarithm of a sum as a sum of logarithms, the same technique which is the basis of the modern electronic. Since an analogical machine was being used, the variable could be of any value (not only discrete prefixed values). With a polynomial equation, the wheels representing the unknown spin round, and the result gives the values of the sum of the variables.
When this sum coincides with the value of the second member, the wheel of the unknown shows a root.With the intention of demonstrating them, Torres also built a machine for solving a second-order equation with complex coefficients, and an integrator. Nowadays, the Torres machine is kept in the museum at the of the (UPM).See also.References.
