After the Cold War period, with the restructuring of the world, globalization, the revolution in information technology and the reconstruction of capitalism have created a new type of society, the "network society". The dependence of countries on information technologies, especially the internet, has increased day by day, and it has…

The standard model of particle physics is the most successful theory describing the behavior of matter and energy in the subatomic realm. However, success doesn't mean it is perfect, and a recent measurement of the mass of a particle called the W boson is puzzling, as it disagrees with theoretical predictions and earlier precise measurements. If…

It has been over thirty years since the nuclear reactor meltdown at the Chernobyl nuclear power plant, but why there is still an officially designated exclusion zone? The Chernobyl Disaster Task combines the learning of exponential functions with properties of radioactive substances to help students understand the ongoing effects of the meltdown.…

The principles of process-oriented guided inquiry learning (POGIL) are applied to the analysis of the emission spectrum of atomic hydrogen. Over the course of three learning cycles, students construct the hydrogen atom's energy level diagram and assign quantum numbers using their measurements of the Balmer series plus additional information on the…

Pulsed field gradient nuclear magnetic resonance (NMR) is used to estimate the size of quantum dots (QDs) produced in a simple, fast, small-scale synthesis. This upper-division laboratory experiment teaches the basics of QD synthesis and pulsed field gradient NMR, a powerful technique for measuring diffusion coefficients in solution. The diffusion…

From climate disaster to the specter of nuclear annihilation to the rise of fascism and destruction of democracy to the advent of AI and other potentially destructive technologies, a number of material threats are matched by symbolic threats that undermine the capacities of people to respond. The war on public and critical education and the public…

This paper presents a cooperative learning activity on a nuclear power plant to develop students' reasoning skills on socioscientific issues. To this end, the steps in the implementation of the activity have been given in detail. The activity was implemented in an undergraduate course with senior preservice science teachers, whose reflections were…

Nanotechnology has been recognized as an important driver of the future economy, and so nanoscience is increasingly being incorporated into the undergraduate chemistry curriculum. This experiment includes the chemical synthesis, optical and chemical testing, and microscopic imaging of gold nanoparticles. Since nanoparticles are too small to…

This project uses critical place inquiry (Tuck & McKenzie, 2015) to examine the Hanford Site to demonstrate the potential in wild pedagogies to engage not just immaculate and inspiring wildness places but also sites of ruin. Attending to places of ruin can illuminate the ways that the social, historical, and political are intimately…

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.

Recent research emphasizes the need for a more sustained interaction of schools with universities and research institutions. For example, informal after-school programs integrated into the school curriculum can provide opportunities for meaningful interaction with researchers in active learning settings. At the physics department of University of…

This article aims to introduce the actinides and some aspects of nuclear chemistry to teachers and their students. The actinides are a group of f-block elements with atomic numbers from 90 to 103. (The term 'actinoids' encompasses both the actinides and actinium itself). All of the actinides are radioactive but they also have a rich inorganic…

For several years, I taught a general education course on the Manhattan Project for students majoring in the arts and humanities who needed a physical science credit as a condition of their graduation requirements. As might be imagined, the challenge in teaching this course was to find a balance between quantitative and qualitative content. A…

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…

This article considers best practices for writing articles in science, technology, and policy, focusing on writing for international scholarly journals in nuclear security. Its two main audiences are technical communication educators/researchers and internationals wishing to publish their work in English-medium scholarly journals. I discuss…
