I graduated in Physics in Complutense University of Madrid and I have been teaching mathematics in secondary schools for more than thirty years. I received my Ph.D. in June 2004 at the University of the Basque Country, UPV-EHU. My studies have been on mathematics and physics studied by military men during 17th and 18t century Spain. I have also worked on teaching of arithmetic, geometry, especially of Euclid's Elements, and the geometrical instruments used during those centuries.
