behavior, which has been considered as a signature of Anderson localization of light in random systems. We show that in dilute clouds, the center of the energy distribution is described by Wigners semicircle law in the scalar and vectorial cases. For dense gases, this law is replaced in the vectorial case by the Laplace distribution. Finally, we show that in the scalar case the degree of resonance overlap increases as a power law of the system size for dilute gases, but decays exponentially with the system size for dense clouds.

We show that in atomic gases cooperative effects like superradiance and subradiance lead to a potential between two atoms that decays like 1/r. In the case of superradiance, this potential is attractive for close enough atoms and can be interpreted as a coherent mesoscopic effect. The contribution of superradiant pairs to multiple scattering properties of a dilute gas, such as photon elastic mean free path and group velocity, is significantly different from that of independent atoms. We discuss the conditions under which these effects may be observed and compare our results to recent experiments on photon transport in cold atomic gases.

ABSTRACT A course entitled ‘Science and Engineering Education: Interdisciplinary Aspects’ was designed to expose undergraduate students of science and engineering education to the attributes of interdisciplinary education which integrates science and engineering. The core of the course is an interdisciplinary lesson, which each student is supposed to teach his/her peers. Sixteen students at advanced stages of their studies attended the course. The research presented here used qualitative instruments to characterise students’ attitudes towards interdisciplinary learning and teaching of science and engineering. According to the findings, despite the significant challenge which characterises interdisciplinary teaching, a notable improvement was evident throughout the course in the percentage of students who expressed willingness to teach interdisciplinary classes in future.

In the Department of Electrical Engineering at the Technion—Israel Institute of Technology—a unique course is being held—“Introductory Project in Electrical Engineering”. The course is intended to expose second-year students of electrical and computer engineering to the occupational areas of electrical and computer engineers, to strengthen their sense of relatedness to the Department and increase their intrinsic motivation towards their studies. The core of the course is a team project for planning a window-cleaning robot. Using quantitative and qualitative tools, the study described in this paper has followed students who participated in the course, examining changes in the motivational factors driving them to study electrical and computer engineering. Findings point out a significant improvement in students’ intrinsic motivation and identified regulation—an improvement explained in light of the self-determination theory.
