An elementary-level physics approach is used to calculate a number of interesting and useful quantities related to nuclear explosions. The set of eight exercises deals with nuclear fission fragments, the variation of fissile nucleus density in a fissioning nuclear device core with time, and the fireball.

In this paper it is demonstrated how the free, and easily downloadable, software package called SMath Studio can be used to set up a model of alpha-particle scattering. The basic physics of the motion of an alpha-particle in the nuclear coulomb field is used to produce a simple stepwise computer algorithm which, in conjunction with a novel set of…

We propose discussions and hands-on activities for GCSE and A-level students, covering a fundamental aspect of nuclear physics: the concept of bonds and the energy released (absorbed) when a bond is created (broken). This is the first of the series of papers named "A teaching guide of nuclear physics", whose main goal is to provide…

Nuclear energy produces low carbon, safe and reliable electricity so is it now time for the UK to invest in this proven technology or are the misplaced perceptions regarding its safety, cost and the quantities of radioactive waste produced causing us to overlook nuclear as a major component of our electricity mix? This paper discusses these issues…

Although infinite potential 'particle in a box' models are widely used to introduce quantised energy levels their predictions cannot be quantitatively compared with atomic emission spectra. Here, this problem is overcome by describing how both infinite and finite potential well models can be used to calculate the confined energy levels of…

We present a new teaching and outreach activity based around the construction of a three-dimensional chart of isotopes using LEGO® bricks. The activity, "binding blocks", demonstrates nuclear and astrophysical processes through a seven-meter chart of all nuclear isotopes, built from over 26000 LEGO® bricks. It integrates A-Level and GCSE…

This article presents a web-based educational project focused on the potential value of Information and Communication Technology to enhance communication and education on nuclear science throughout Brazil. The project is designed to provide trustworthy information about the beneficial uses of nuclear technology, educating children and teenagers,…

Radiation, radiation detection and radiation protection are topics in physics and its applications which generate a wide interest in the public. This interest is either generated through medical procedures, applications of nuclear energy or nuclear accidents. The technical nature of these topics usually means that they are not well covered in the…

The Billotron is a device designed and built by the LPC Caen to illustrate the methods with which physicists are able to study the basic structure of matter, in particular the nucleus of the atom.

The paper describes a teaching model of the atomic force microscope (AFM), which proved to be successful in the role of an introduction to nanoscience in high school. The model can demonstrate the two modes of operation of the AFM (contact mode and oscillating mode) as well as some basic principles that limit the resolution of the method. It can…

Discusses principle themes/issues of risk assessment, using examples from the "nuclear debate." Indicates that while an objective scientific core to decisions on risks exists, this is conditioned in its interpretation by inexactness, uncertainty, and value-commitments. Considers risk assessment elements, risk quantification in real…

Energy policies are under review everywhere, as the world tries to meet targets for reducing climate change despite continuing population growth. A major change in energy patterns is needed, with the critical period for transition predictably happening when young people currently at school are in their middle years of their lives. This article…

Investigates Italian high school and college students' awareness of the risks connected with both the civilian and military uses of nuclear energy. Summarizes some findings of this analysis and concludes that the education regarding nuclear issues does not meet current needs. Provides a questionnaire on nuclear issues. (YP)

Describes some research studies, contents of a videotape, students' discussion of nuclear power and other educational aspects of the topic. Ten references are listed. (YP)

Discussed are some areas of overlap between physics and astronomy. Topics include solar power, fusion reactions, atmospheric refraction, solar spectrum, Doppler effects, Hubble constant, quasars, redshift and the expanding universe, sunspots, sundial construction, solar spectroscopes, the moon, optics, wave theory, the history of science,…
