Una propuesta sobre enseñanza de la relatividad en el bachillerato como motivación para el aprendizaje de la física
2007
Relativity is a very important part of modern physics. In this paper we analyze the teaching and learning of the theory of relativity in secondary education and we show some reasoned arguments against traditional methods to teach it. Finally, a didactic proposal for the teaching of relativity is presented; it comes as a conclusion that it is possible a suitable teaching of the principles of relative which should bring into the students a change in attitude, concepts and methodology.
Journeys from quantum optics to quantum technology
2017
Sir Peter Knight is a pioneer in quantum optics which has now grown to an important branch of modern physics to study the foundations and applications of quantum physics. He is leading an effort to develop new technologies from quantum mechanics. In this collection of essays, we recall the time we were working with him as a postdoc or a PhD student and look at how the time with him has influenced our research.
The introduction of modern physics: overcoming a deformed vision of science
1993
In this paper, we try to show initially that modern physics is usually introduced in high school curricula without reference to the difficulties of classical physics, simply juxtaposing the two paradigms or even mixing them up. As a result, serious misconceptions arise. We then present another way of introducing modern physics, based on a constructivist view of science learning, and give some results obtained with the new materials.
An inquiry-based learning path to introduce modern physics in high-school
2018
Although Modern Physics (MP) is a scientific field of increasingly interest, due to its mathematical and conceptual difficulty, it was not generally taught in Italian high-schools. Recently, in order to reduce the gap between school curricula and modern technology, the Ministry of Education promoted the inclusion of MP in Italian secondary schools. MP hot topics produce interest and enthusiasm in learners at all ages, but to address this topic in high school in an effective way it is necessary to translate complex theories and highly-advanced experiments into an understandable language appreciated by students. In this contribution, we discuss an inquiry-driven learning sequence suitable to …
Implicaciones de la evolución histórica de algunos conceptos en la enseñanza de la Relatividad
2006
La relatividad es una parte importante de la fisica moderna. En este articulo se analiza el debate en torno a la utilizacion de la historia de la ciencia para orientar la didactica de la relatividad en la ensenanza secundaria. Se repasa la evolucion historica de algunos conceptos clave de la relatividad especial y se muestra su implicacion en la ensenanza-aprendizaje.Palabras clave: ensenanza-aprendizaje; relatividad; historia de la ciencia.Implications of the historical evolution of some concepts in the teaching of relativityThe relativity is an important part the modern physics. In this article we analyze the discussion around the use of the history of science to guide the didactics of th…
Quantum Mechanics as a Semantic Problem
2018
Physics, like all science, is grown out of a desire to understand the world. However, modern physics with its mathematical form has become increasingly removed from the world of everyday experience and visual imagination. In quantum mechanics it is impossible to visualize the reality represented by the theory. All we have is a consistent mathematical structure. Although the theory works perfectly well instrumentally, the question remains, how can the mathematics of the theory impart understanding? If we look at mathematics as a language, we are faced with the semantic problem: how does the language of mathematics acquire meaning? In an attempt to answer this question, I study Derrida’s earl…
Focus on modern frontiers of matter wave optics and interferometry
2012
The level of experimental control and the detailed theoretical understanding of matter wave physics have led to a renaissance of experiments testing the very foundations of quantum mechanics and general relativity, as well as to applications in metrology. A variety of interferometric quantum sensors surpasses, or will surpass, the limits of their classical counterparts, for instance in the measurement of frequency and time or forces such as accelerations due to rotation and gravity with applications in basic science, navigation and the search for natural resources. The collection of original articles published in this focus issue of New Journal of Physics is intended as a snapshot of the cu…
From led light signboards to the Planck’s constant
2018
Recent studies have highlighted an alarming decline in young people’s interest towards the study of scientific subjects, often considered interesting but not easily understood and appreciated by students. In particular, the introduction of Modern Physics (MP) key-topics at secondary school level is a difficult and complex task because MP involves abstract ideas and requires a strong mathematical background. In this communication we present and discuss the results of an inquiry-based teaching/learning path aimed at surmounting the difficulties of an exclusively theoretical approach to the introduction of MP topics. In particular, we planned and realized an inquiry-driven learning environment…

Quantum technologies and the elephants
2021
Extraordinary progress in quantum sensors and technologies opens new avenues for exploring the Universe and testing the assumptions forming the basis of modern physics. This QST focus issue: focus on quantum sensors for new-physics discoveries is a next-decade roadmap on developing a wide range of quantum sensors and new technologies towards discoveries of new physics. It covers the next generation of various technologies, including atomic and nuclear clocks, atomic and diamond-based magnetometers, atom and laser interferometers, control of trapped atoms, ions, and molecules, optomechanical systems, and many others. In this editorial, we outline major problems of fundamental physics we aim …
