This Catalyst article takes a look at Mount Etna on the Italian island of Sicily, the biggest and tallest active volcano in Europe and one of the most active in the world. The article explores the geology of the volcano, its history and the local habitat surrounding it including how the volcanic conditions create...

This Catalyst article looks at metals and alloys which play an important role in construction at the Olympic site, both in sports equipment and in medals. Designers must consider the properties of the materials used to make both sports equipment and buildings. These include strength, density, toughness, ductility...

This Catalyst article looks at how computer games make increasingly sophisticated use of the laws of physics to produce convincing on-screen effects. From calculating the angle that a ball bounces off a wall to modelling the frictional forces on a rally car, physics has always played a part in the development of...

Palaeontology strives to discover evidence so that we might learn more about the fossil remains of life and understand how they lived, functioned and even died. Scientists at The University of Manchester have been using state-of-the art imaging, chemical analyses and computer modelling techniques to study the...

Heating accounts for over half of the energy used in homes in the UK. This Catalyst article looks at buildings designed to cut heating demand almost to zero. There are over 70,000 passive houses in Europe – just a few of them in the UK. To be described as ‘passive’, a house must meet strict criteria for energy use...

This Catalyst article explores how cyclists can use physics to explain certain limitations to their performance. Variables which may affect a cyclist's speed such as force, energy and power are considered along with formulas for calculating the correct amount of each in order to optimise performance.

The...

A Catalyst article about the International Year of Physics, in 2005, also known as Einstein Year. In the century since Einstein’s “annus mirabilis”, when he developed his theory of relativity there has been a revolution in the study of physics. This article explores the links between some of the architects of this...

A Catalyst article about the video or computer games industry which is now the biggest entertainment-based industry on the planet. Often it is physicists developing new concepts, hardware and games. To beat the competition they need to make physical aspects of the game be more realistic or at least appear to be...

A Catalyst article about the use of remote telescopes and detecting cosmic rays. Giant telescopes that can be operated remotely are located in Hawaii and Australia and are known as the Faulkes telescopes.

These are available to students in the UK to do original research with, and enable the following...

The seven posters can be used in class when children are engaged in a space topic. Each file contains an image and a description associated with the image, in large font type. The posters are: constellation; galaxies; nebula; planets; solar system; sunspots; and the sun. The remaining files are articles from The...

This Catalyst article looks at 3D printing, a new technology which is rapidly finding applications. Although probably too slow for mass production it is useful for producing prototypes and tailor-made items. In a 3D printer, layers of polymer beads are printed one on top of the other. Heat melts the polymer beads...

This School Science Review article looks at a selection of resources currently available for use in the teaching of astronomy in UK schools. It is by no means an exhaustive list but it highlights a variety of free resources that can be used in the classroom to help engage students of all ages with astronomy and...

Published by the Nuffield Foundation, this background reader was compiled to support Unit G 'Energy sources' in the Revised Nuffield Advanced Physics course. This book contained a collection of articles related to energy options. The articles were not written specially for the course but were selected from a range...

Published by the Nuffield Foundation, the articles in this Revised Nuffield Advanced Physics reader are extended concepts covered in the course and examined developments in physics taking place in the 1980s.

A Catalyst article comparing mobile phones and UV sunbeds. Mobile phones emit radiofrequency (RF) radiation. Tanning beds emit ultraviolet (UV) radiation. These are both types of non-ionising radiation. In recent years both have received considerable media coverage and they are emotive topics for the general public...
