Which seems to have come off sciences, but it is not thus, she is in the primitive essence pertaining to all scientific knowledge. One of the greatest humanists talks about to the mathematical one of a precious way. Juan Luis You live and its great work the disciplines, illustrates something to us wonderful about the same. Then these were not affected by the plagiadores and commentators, who wishing to reach glory, handled works of the old ones. It says: " those arts that turned about the cuantidad llamronlas the Greek mathematics.
that is equivalent to say disciplined! To the double cuantidad hicieronla, of volume and I number, unique is the discipline that deals with the cuantidad of the volume. To that the Earth measurement llamronla geometry. Unique it is also the discipline that deals with the cuantidad of I number, that is to say: the Arithmetic whose etimologa gives to understand the matter. The geometry transferred to the celestial sphere made astronomy. I number applied to the harmony made music. The sizes, in relation to the force and the visibility, reported that one of the mathematics that are called perspective and the one to us that called optics the Greeks. To if all these hijuelas of the mathematics, two are simple or universal arts and three compound ones or space. Like derived from the majority.
They were not discovered but, or because they did not apply intention to but diligent investigations or because in spite of its efforts. They could not obtain the auditory one, as they secured the perspective. Of that one, of the auditory one, I say, some to I avoid, like that show with the finger, made some hints about how the sound extends by the air, as the echo takes place, of the sounds which they are heard close and far, of the resonance, the cavities and some others fenmenos".
