Discovering light. Introducing interference and diffraction

Light plays a fundamental role in our lives and optics and photonics have a huge and ever increasing importance in a wide range of industries and impact in our modern societies. It is therefore essential that a solid knowledge on this subject is acquired as early as possible, right from primary school or even at kindergarten, in a process of active and participated discovery by the pupils themselves who naturally have an empathy, interest and special curiosity for this Light and Optics subject as it directly relates to vison, one of our major sense

Eddington & Uncertainty

Sir Arthur Eddington is considered one of the greatest astrophysicist of the twentieth century and yet he gained a stigma when, in the 1930s, he embarked on a quest to develop a unified theory of gravity and quantum mechanics. His attempts ultimately proved fruitless and he was unfortunately partially shunned by some physicists in the latter portion of his career. In addition some historians have been less than kind to him regarding this portion of his work. However, detailed analysis of how this work got started shows that Eddington's theories were not as outlandish as they are often purported to be. His entire theory rested on the use of quantum mechanical methods of uncertainty in the reference frames of relativity. Though the work was ultimately not fruitful, in hindsight it did foreshadow several later results in physics and his methods were definitely rigorous. In addition, his philosophy regarding determinism and uncertainty was actually fairly orthodox for his time. This work begins by looking at Eddington's life and philosophy and uses this as a basis to explore his work with uncertainty.Comment: new version to appear in Physics in Perspective (either Sept. or Dec. issue

Aprender colaborando. La enseñanza-aprendizaje de la lengua extranjera inglés mediante trabajos cooperativos

En este Trabajo de Fin de Grado se pone de manifiesto una alternativa para la enseñanza de una asignatura impartida en lengua extranjera, poniendo en práctica y analizando el trabajo cooperativo en el aula. Se persigue renovar la metodología de la enseñanza de la lengua extranjera en las aulas, empleando un método más activo y motivador que involucre a los estudiantes en su propio aprendizaje y que les permita resolver ciertas situaciones. El trabajo por cooperativo proporciona una variedad de opciones de aprendizaje en el aula, ya que, les permite explorar sus áreas de interés dentro del marco del currículum, se fomenta la motivación y el interés por aprender de los alumnos a la par que se desarrollan las destrezas comunicativas.Grado en Educación Primari

Experimental validation of opto-thermo-elastic modeling in OOFELIE Multiphysics

The objective of this work is to demonstrate the correlation between a simple laboratory test bench case and the predictions of the Oofelie MultiPhysics software in order to deduce modelling guidelines and improvements. For that purpose two optical systems have been analysed. The first one is a spherical lens fixed in an aluminium barrel, which is the simplest structure found in an optomechanical system. In this study, material characteristics are assumed to be well known: BK7 and aluminium have been retained. Temperature variations between 0 and +60°C from ambient have been applied to the samples. The second system is a YAG laser bar heated by means of a dedicated oven. For the two test benches thermo-elastic distortions have been measured using a Fizeau interferometer. This sensor measures wavefront error in the range of 20 nm to 1 μm without physical contact with the optomechanical system. For the YAG bar birefringence and polarization measurements have also been performed using a polarimetric bench. The tests results have been compared to the predictions obtained by Oofelie MultiPhysics which is a multiphysics toolkit treating coupled problems of optics, mechanics, thermal physics, electricity, electromagnetism, acoustics and hydrodynamics. From this comparison modelling guidelines have been issued with the aim of improving the accuracy of computed thermo-elastic distortions and their impact on the optical performances

Old anatomical models as makeshifts of measurements in medicine

In 18th century obstetrics became a special branch of medicine, with a corpus of physiological and practical knowledge sufficient to improve the outcome of childbearing. The same period also saw the emergence of new techniques and the development of instruments that would later come into widespread use, such as the forceps, as well as the first production of teaching models to provide surgery students and midwives with three-dimensional illustrations of the anatomy of the pregnant woman, the physiology of childbearing, and potential complications. Some obstetrical wax models, that can be considered makeshifts of measurements in medicine, are illustrated. They are exposed, in number of twenty-one, in the Galileo Museum of Florence and were commissioned, around 1770, by Felice Fontana, who was working on the installation of the Museum of Physics and Natural History of Florence, from the sculptor Giuseppe Ferrini and his assistant Clemente Susini. The anatomical models contributed, in a context in which the measurement was not easy to be taken in situ, to formalize medical knowledge, strictly tied, in the past, to the various communities, that had different ideas about the causes of and cures for suffering, illness and disease. As a matter of facts, instead of being based on objective parameters, medical knowledge was based often on spiritual beliefs as well as practical therapies and techniques

Profile and competences of Spanish industrial engineers in the European Higher Education Area (EHEA)

The aim of this document is to develop a clear definition of the role of the industrial engineer. This is important in the Spanish context, where the engineer curricula are evolved in a different way than in other countries, due to the role developed by the Professional Associations of Engineers and Technical Engineers. To this end we identify here the professional profiles to be expected of those graduating from such courses, the sectors where they are most likely to be recruited, and the context within which industrial engineers are employed. We deal with meanings and proposals for Industrial Engineers within a European context, drawing information from the academic debate which has been launched in a number of scientific publications. The text summarizes our personal reflections, which are integrated within a proposal for action intended as an additional contribution to the critical debate as to the situation, rather than a final responsePeer Reviewe
