has reminded us in the press today engineer Juan de la Cierva and Sickles,-nephew of the inventor of the autogyro : Juan de la Cierva y Codorniu . (Although the great Leonardo had also this idea) -.
Juan de la Cierva does not consider himself an inventor but " a man who knows math."
"My uncle said he was not the inventor, said he was a mathematician. Anyone who can translate the math problems and dump the results back into reality can be invented, no more mystery. "
in Spain do not have the privilege of having many inventors: the mathematician and engineer Leonardo Torres Quevedo built in 1912 the first chess automaton (including calculating machines analog), which consider the precursor of Robotics.
calculating machines whose first idea is to solve mathematical questions whose solutions are obtained transferring them to physical phenomena.
numbers are represented by physical quantities that can be tions of certain rotational axis, potential, electrical or electromagnetic states, etcetera. A mathematical process is transformed into these machines in an operational process of certain physical quantities leads to a corresponding physical result with the mathematical solution sought. The mathematical problem is solved using a physical model for it.
By the middle of the nineteenth century Charles Babbage had built his Analytical Engine.
their machines Babbage considered not only as aids to make calculations, their inventions also considered a light on the path that shows the existence of an infinite intellect, or Creator.
Babbage came to describe the Creator, as a infinitely skilled programmer.

In 1893, Leonardo Torres Quevedo presented in the Academy of Exact, Physical and Natural of the report on algebraic machines .
The mathematical basis of their machines tuned the transcribing of Wikipedia :
... "In these machines there are certain items, called aritmoforo, which consist of a mobile and an index that allows you to read, the quantity for each position of the same. The phone is a disk or scale drum that revolves around its axis. The angular displacements are proportional to the logarithms of the magnitudes to represent. Using a variety of items like this, put up a machine to solve algebraic equations: solving an equation of eight terms, getting its roots, including complex, with an accuracy of thousandths. A component of that machine was called "endless screw" high mechanical complexity, allowing mechanically express the relationship y = log (10 ^ x +1) , in order to obtain the logarithm of a sum as a sum of logarithms. Since this was an analog machine, the variable can go any value (not only discrete values \u200b\u200bprefixed). To a polynomial equation, turning all the wheels representing the unknown, the end result is giving the values \u200b\u200bof the sum terms of variables, when this sum equals the value of the second member, the wheel of the unknown makes a root. Demonstration purposes, Torres Quevedo also built a machine to solve a quadratic equation with complex coefficients, and an integrator ."...
